Scythes are a solution to Delhi air pollution



Screenshot from NDTV Prime Time program, November 9, 2017


"Delhi has earned the unenviable distinction of becoming the most polluted city on Earth this month, as air quality has reached epically bad proportions... merely breathing the air was, at its worst, like smoking 50 cigarettes in a day..."
-- Vox, November 23, 2017


"Why this spike in pollution?...Farmers in the neighboring states are burning straw from their last rice crop to clear fields for planting the wheat crop... The state of Punjab alone produces about 20 million tons of paddy straw. Roughly 85 to 90 percent of that is burnt in the field."
-- The Washington Post, November 11, 2017


"Stubble burning is the ‘main villain’ behind the severe pollution in Delhi and neighbouring areas, the Delhi High Court said on Tuesday."
-- The Hindu, New Delhi, November 7, 2017


The NDTV news program "Prime Time" looked at how the air pollution is linked to the use of combine harvesters. As seen in the following video (an unofficial translated version), host Ravish Kumar suggests that instead of scapegoating the farmers, we try to understand their plight. He describes how scythes could be part of the solution to India's air pollution problem:

Scythes go viral in India


Screenshot from recent video with 1.3 million views.

Scythes got a lot of attention this past month during the wheat harvest in northern India, thanks to Alexander Vido and Sy Schotz, who travelled there to demonstrate the cradle scythe at numerous villages. This short video was posted on April 1, and got over 1.3 million views in less than a month!

Scythe Initiative in India




Alexander Vido (of Scythe Works) was contacted by a number of enthusiastic people from various parts of India in response to his Scythe Project in Nepal, so he arranged a trip to "lend a hand" where he could. While there, he found that a cradle scythe could successfully harvest paddy rice, as long as it wasn't too ripe. He plans to return in the Spring for the wheat harvest in northern India, where he was invited to assist with the local adoption of scythes (instead of sickles) for the task.

A slideshow of his recent trip can be found at his Scythes in the Developing World site. Here are some samples:

English Scythe "Secrets"






An article titled "Secrets of the Scythe" was published in the July 1938 issue of The Countryman magazine. Perhaps some forgotten aspects of the English scythe can be "rediscovered". Here are some excerpts:

On setting the tang of a new blade:

When a new scythe-blade is bought the tang is flat in the same plane
as the blade. If it were attached to the snath without any adjustment
it would be at a sharp angle to the ground, and the first essential is
that the sole should lie flat on the ground when the mower takes up
his stance. We must therefore take our new scythe to be hung by a
blacksmith...

The instructions regarding the swing (keep the blade level, without raising it at either end of the stroke) and the stance (shift weight from right foot to the left foot as the swing progresses) sound remarkably similar to how present-day "continental" scythes are typically used, although here the swing is limited to about 90 degrees:

Now about stance and swing. The mower stands with his feet about 
2 ft. 6ins. apart and facing slightly to the right of the line of the swathe
he is about to cut. He should balance on his toes, bending slightly
forward. 
The scythe should remain at the same height from the ground,
with the blade level throughout the cut. Swing the scythe to the right
until the point is in line with the shoulders, and take the cut by
swinging to the left, smoothly without slashing. 

As the weight of the body is transferred on to the left foot at the end of the swing,
advance the right foot about 5 ins. The left foot is advanced the same
distance on the return swing. This is what the countryman means when
he says, 'Keep the left foot back so as not to cut your leg'...

Both arms should be used equally during the swing. The
feeling to the mower should be that the left arm is drawing the blade
through the crop, while the right arm, supporting most of the weight,
holds the scythe balanced.

The full text of the article appears at this site and a PDF file can be downloaded there.

I obtained a physical copy of this issue of The Countryman, and the only information that doesn't appear in the PDF are three figures (redrawn below):


Figure 1 represents "the normal way of cutting a straightaway swathe", with the straight line being the edge of the standing crop (grass, etc.) Alternately, Figure 1 shows a way of cutting along a hedge, with the cut starting at the hedge and the swathe "laid against the uncut edge of the crop" (the straight line). Note that the resulting cut from each swing is effectively limited to 90 degrees.

Figure 2 shows a hypothetical semicircular swing, but this is not possible without "a change of stance, and therefore two cuts to each semi-circle."

Figure 3 shows the recommended way of cutting along a hedge into an uncut field, with two swaths.  At first, the cut is made along the hedge and the swathe deposited against the uncut edge of the crop (the straight line). Then, the mower "turn[s] and cut[s] the standing crop in the opposite direction, laying the second swathe on top of the first."

[Note: In the above descriptions, "swathe" is sometimes synonymous with "windrow"]


During the same year that this article was published in The Countryman (1938), a documentary film titled English Harvest was produced. Early in the film, an English scythe is used to open the field for harvesting by a horse-drawn reaper-binder.
 




Shown below is a book from 1899 containing an essay titled "The Decline of Harvest" which looks with disdain upon this type of self-binding reaping machine (as seen in the video), and recalls scythes with nostalgia:



...there can be nothing more saddening than the change which has come over the harvest field during the last 30 years. In the 'sixties it was no uncommon thing -- in spite of the gradual inroads which the mechanic and his machines had then made into rural industries -- to find a typical old English harvest scene in the corn-yielding districts. As you went about the land what time the air was fragrant with the scent of ripened barley, you came across some broad-acred field where the standing corn was being cut in the primitive fashion with scythe and sickle, and where the scene which almost every English landscape painter has striven to depict on canvas was apparent in its natural truth. You heard the swish of the scythe...

How different it all is nowadays! ...There is not at first sight a sign of life in the field. Then you are aware of a curious, whirring, rattling, peace-destroying sound on the other side of the still standing corn, and you see across its waving expanse the heads of horses, the heads of a couple of labourers, and with them a fanlike Thing which goes round and round and round, striking into the crop with mechanical regularity. You wait half-fascinated until the Thing approaches you, and as it draws nearer its roar and rattle becomes harsher and more terrifying.


...the advent of the "self-binder" has changed everything and to a certain extent the glory of the harvest time is over...  there are times when one experiences a feeling of vague, restless regret that the old things have passed away, and that the English harvest-field scenes of our grandfathers' days are not to be seen in ours.

Addendum -- February 2, 2014:

The Phoenix Works (T. & J. Hutton & Co. Ltd.) was the last remaining scythe and sickle works operating in Britain until its closure in 1988. This company published an instructional booklet that appears at the Ridgeway History Website, and some photos from that site (from Frank Fisher's collection) are linked below:

Russian variations





When it comes to scythes, the Russians evidently do some things differently (compared with the typical Western European ways).  Some of these Russian methods are presented below. Seeing different approaches to familiar problems can benefit one's understanding, creativity, and improvisation potentials.

The drawings appearing below are linked images from the Russian site Pandia.ru and originated from a magazine article titled кoси, кoса by Н. Н. Рoдиoнoв, appearing in the journal Сделай Сам (Знание) 1992-02 [journal name translated as DIY (Knowledge)].

Here is a Russian scythe with a moveable grip. The advantages of such a grip include having a wide range of adjustments possible for different conditions or different users.



The grip is made from a freshly-cut branch that is bent around the snath and secured with a piece of twine.  Willow or wild cherry is suggested, with a diameter of 25-30 mm and a length of 350-400 mm.  The size of the cutout portion in the middle depends on the diameter of the snath, but is typically around 80 mm, with a depth that's less than half of the branch diameter. A groove is made within the cutout portion, removing the pith and the center of the branch to accommodate bending without breakage.  Grooves are carved around each end of the branch to hold the twine in place, once the handle is bent around the snath.  A thin piece of rubber (like a scrap from an inner tube) between the grip and the snath will make the connection more secure during use.



Although one-grip snaths seem to be the norm in Russia, this unusual style of two-grip snath was shown as an example from Lithuania: 




The blade attachment method (shown in the first drawing above) uses one or two non-adjustable rings in combination with a substantial wooden wedge. This type of wooden wedge is used with a snath having an acutely tapered end. The snath taper is evident in the drawing below which illustrates an alternative grip arrangement:




Having the snath end taper like this, instead of being squared off, will effectively make the blade perform like it has a steeper tang, which can be good for low tangs and/or tall folks. Here's a photo from Peter Vido that shows a blade attached to a tapered snath using a wedge and simple ring (with no set screws):


From ScytheConnection.com: A snath with a very acutely tapered end. For this arrangement the common set-screw type rings do not work well. However, the simple ring in the picture, held in place by a thick wedge, is a very common way of attaching a blade; many East European and other mowers prefer this method. It is in this manner that most Russian-made blades (the tangs of which are approximately 23-24 degrees) have been used on the straight one-grip snath in Slovakia by tall mowers. For this ring/wedge to hold better, the upper side of the snath’s end remains square, i.e. flat on top, instead of rounded as it would be in order to take the set-screw ring. http://scytheconnection.com/snath-and-blade-fitting/



Another method of blade attachment is this clamp, which has a lever arm and a cam:





Peening the blade is done while on the snath or off, with anvils and hammers similar to those used throughout Europe:





The Russian-style peening jig, however, is different. Instead of having a hammered cap that fits over and around a central post, the Russian jig has a hammered post that fits within a round guide:





While the design of this jig is more complex, one apparent advantage is that without a fixed central post, the part of the blade being peened is not butted against anything during the deformation, and therefore would not be dulled by the hammering. This jig has two set screws, one to hold the bottom anvil piece in place, and the other to align the hammer post and keep the up and down movements within limits.




Along with a whetstone, some Russian mowers will carry a smooth, hard steel rod into the field with them to use like a butcher's steel (labeled 2, below).




The function of the steel is to realign the edge and recover some sharpness without having to wear down the edge with the stone. During normal use of the scythe, some of the microserrations in the edge become folded over, dulling the blade. Using the steel can reposition portions of the bent edge back into the original position, restoring the sharpness to a certain extent. Some of the regular honings in the field can be replaced by steeling the edge, effectively prolonging the life of the edge. Another Russian site suggests making this scythe sharpening steel from an old triangular taper file that has been smoothed to remove the file teeth.



Below is a Russian design for grain cradles, made from durable, dry wood, with 3-5 "teeth" (depending on the height of the grain):



1 = Teeth, fitting into 12x12 mm holes in Base

2 = Rawhide straps
3 = Base, 20x20 mm wood, length 350-600 mm
4 = Ring
5 = Twine

The wooden base is firmly attached to the snath with a steel bracket, with one end of the bracket attached to the base using two screws, and the other end of the bracket clamped between the snath ring(s) and the blade tang. The lowest tooth is slightly shorter than the blade, and each upper tooth is 50-70 mm shorter than the tooth below. The teeth are sanded smooth to avoid burrs. Dry rawhide straps are twisted to connect and separate the teeth. Wet rawhide straps are used to help firmly secure the teeth to the base, tightening as they dry. The ring is attached to the snath about 15 cm below the grip, and strong twine is stretched between the teeth and the ring, for additional stability and adjustment potential. All of the teeth should be arranged parallel to the cutting edge of the scythe blade. Fabric or netting can be added,if desired, using a U-shaped frame attached to the snath (not shown).

Take-apart Travel Snath




Alexander Vido (of ScytheWorks) designed this compact snath for his recent travels to Nepal.


The two halves of the one-grip snath are coupled by a piece of 1-1/4" copper pipe, with a bolt holding each half in place.  Attached to the removeable grip is a hanger bolt which passes through both halves of the snath (note the diagonal joint) and secures the grip to the pipe. 


                                                                           

The grip can be attached to any of the three holes, making the snath adjustable to the user's height; and the orientation of the grip can be changed to make it suitable for right-handed and left-handed users (with the appropriate blade, of course).





In the photo below, Alexander demonstrates the use of this scythe to cut wheat, using a grain cradle that he also designed.  (More about this cradle in a future post.) 






Additional information about the Scythe Project in Nepal (SPIN) can be found here.  
An excellent video showing this scythe being demonstrated in Nepal can be found here.  


Kudos to Alexander for imagining, planning, and implementing this worthwhile project!

Reaping Rye, Wheat, Barley, Oats...




Here, stretched in ranks, the swelled swarths are found.
Sheaves heaped on sheaves here thicken up the ground. 
With sweeping stroke the mowers strew the lands— 
The gatherers follow and collect in bands; 
The rustic monarch of the field descries, 
With silent glee, the heaps around him rise." 
-- from Homer's "Iliad", A. Pope translation


All material quoted from:
The book of the farm: detailing the labors of the farmer, steward, plowman, hedger, cattle-man, shepherd, field-worker, and dairy maid, Volume 2,  by Henry Stephens, 1852,
Chapter 34 (page 373 onward)


In mowing, it is the duty of the mower to lay the cut corn [meaning "grain"] or swath at right angles to his own line of motion, and the straws parallel to each other...To maintain this essential requisite in corn [grain]-mowing, he should not swing his arms too far to the right in entering the sweep of his cut, for he will not be able to turn far enough round toward the left, and will necessarily lay the swath short of the right angle; nor should he bring his arms too far round to the left, as he will lay the swath beyond the right angle; and, in either case, the straws will lie in the swath partly above each other, and with uneven ends, to put which even in the sheaf is waste of time. He should proceed straight forward, with a steady motion of arms and limbs, bearing the greatest part of the weight of the body on the right leg, which is kept slightly in advance...The sweep of the scythe will measure about 7 feet in length, and 14 or 15 inches in breadth. 


The woman-gatherers follow by making a band from the swath, and laying as much of the swath in it as will make a suitable sheaf...The gatherer is required to be an active person, as she will have as much to do as she can overtake. The bandster follows her, and binds the sheaves in the manner already described, and any 2 of the 3 bandsters set the stooks  together, so that a stook is easily made up among them; and in setting them, while crossing the ridges, they should be placed on the same ridge, to give the people who remove them with the cart the least trouble. 


Last of all comes the raker, who clears the ground between the stooks with his large rake of all loose straws, and brings them to a bandster, who binds them together by themselves, and sets them in bundles beside the stooks. This is better than putting the rakings into the heart of a sheaf, where they will not thresh clean with the rest of the corn; and, moreover, as they may contain earth and small stones, and also inferior grain, from straws which may have fallen down before the mowing, it is better to thresh bundles of takings by themselves.


The figure [above] exhibits the 3 kinds of scythes in operation [along with the other workers doing the described tasks].


A scythesman will cut fully more than 1 imperial acre of wheat in a day. Many farmers affect to believe that the scythe is an unsuitable instrument for cutting wheat; but I can assure them, from experience, that it is as suitable as the sickle, and that mown sheaves may be made to look as well as reaped. No doubt mowing wheat is severe work, but so is reaping it. Of oats, 1 scythesman will mow fully 2 acres with ease. The oat crop is remarkably pleasant to handle in every way; its crisp straw is easily cut by the scythe, and being hard and free, and generally not too long, is easily bound in sheaf and set in stook. Nearly 2 acres may be mown of barley; but the gummy matter in the straw, which gives it a malty smell, causes the stone to be frequently used in mowing barley, and the straw being always free, the bands are apt to break when rashly handled in binding the sheaves.


One mode of setting up corn [grain] to dry quickly is in gaits, that is, the band of the sheaf is tied loosely round the straw, just under the corn, and the loose sheaf is made to stand upon the lower end of its straw being spread out in a circular form, and they are set upon every ridge. The wind whistles through the open sheaf, and even the rain passes through, and does not hang upon it. 


The expedient of gaiting, however, is only practiced in wet weather, and even then only should the crop, if allowed to stand, be endangered by a shaking wind. It is confined also to a particular kind of crop, namely, oats—wheat and barley never being gaited, because when wheat gets dry, after being cut in a wet state, it is apt to shake out in binding the gaits; and when barley is subjected to the rough usage of binding, after being won, the heads are apt to snap off altogether, and, besides, exposure in gaits would injure its color, and render it unfit for the maltster. Oats are protected by a thick husk, and the grain is not very apt to shake out in handling, excepting potato-oats, which are seldom gaited, the common kinds only being so treated. But, for my part, I would not hesitate to gait any sort of oats when wet with dew in the morning, or even when wetted with rain, rather than lose a few hours' work of reaping every morning, or at nightfall. 


Gaits, it is true, are very apt to be upset by a high wind; but after having got a set, it is surprising what a breeze they will withstand. After being blown down, however, they are not easily made to stand again, and then 3 at least are required to be set against each other; but whatever trouble the re-setting them should create, they should not be allowed to lie on the ground, and it will be found that a windy day dries them very quickly, and secures their winning.


Rye may be reaped or mown in the same manner as the other cereal crops. Its straw, being very tough, may be made into neat slim bands. It usually ripens a good deal earlier than the other grains; and its straw being clean and hard, does not require long exposure in the field, and on that account the stooks need not be hooded.


Beans in drills are reaped only with the sickle, by moving backward, taking the stalks under the left arm, and cutting every stalk through with the point of the sickle. When beans are sown by themselves straw ropes are required for bands; but when mixed with pease, the pea-straw answers the purpose. 


Beans are always the latest crop in being reaped, sometimes not for weeks after the others have been reaped and carried. In stooking, bean-sheaves are set up in pairs against one another, and the stook may consist of 4 or more sheaves, as is thought most expedient in the circumstances for the winning of the crop, the desire being to have them won as soon as possible, to get the land sown with wheat. 


Pease are also reaped with the point of the hook, gathered with the left hand, while moving backward, and laid in bundles, not bound in sheaves, until ready to be carried, and are never stooked at all.


-- Henry Stephens, 1852

Grain cradle design from Slovakia








These photos show the classic type of grain cradle used in Central Slovakia.














































.










This simple design requires only a short length of chain, a suitable tree branch (or sapling), some cord, and a screw at the end of the one-grip snath.

The loop of chain is used to loosely attach the branch to the snath, as shown in this photo.
















Moving the branch into position will then tighten the chain and hold the branch firmly against the snath.
















When the branch is perpendicular, the chain is tight and the branch starts to bend.















The snath grip acts as a brace to hold the branch in place while the scythe is being used.















The cord is tied to the branch and looped around a screw at the end of the snath.
















After making easy adjustments to the length of the cord and the position of the chain, the grain cradle is ready for use.














Peter Vido has this to say about grain harvesting and this cradle design:


"This rather quickly written piece on a very pertinent subject is meant as a provisional response to the growing interest in the grain harvesting scythe, often referred to as a “cradle scythe”. 



To begin with, I’d like to present some “facts” (call them opinions if you wish), which I intend to substantiate here at a later date.

  1. For harvesting relatively small (family bread supply- size, for instance) plots of grain, the sickle (rather than the scythe) may well be the tool of choice.
  1. For larger acreages of grain than you may feel like tackling with a sickle, the grain-harvesting outfit traditionally used in Central Slovakia is a relatively simple and efficient alternative.
The body of the cradle consists of a green (and thereby flexible) hardwood branch or thin sapling and a piece of string. (The wooden piece used in these pictures is a branch of a wild plum – hence all the knots.) The string is tied to the end of the branch as well as a small nail/screw/staple at the lower end of the snath. By lengthening or shortening the string, the branch is pulled into a position most suitable, depending on the height of the grain, to hold the cut stalks. The weight of this cradle is a fraction of the more complicated contraptions – and, most importantly – is easily owner-made!

  1. None of the snaths mounted with a cradle that I have seen in museums in several countries (as well as pictured in books) had the lower grip facing backwards (meaning toward the person operating them). This was the case even in regions where the general purpose (“grass”) scythes had their grips pointing backwards – the way the now popular version of Austrian/European snaths have them.
The logic of the upward (and at the same time slightly forward) pointing grips will be apparent to anyone who actually tries out the two options, side by side…
In any case, I think that the folks in the UK (using the Swiss made snath version sold by the Scythe Shop along with the cradle made by Steve Tomlin), as well as all those buying their “grain scythes” from Scythe Supply and Botan Anderson (mystic prairie) will end up working a lot harder for their bread than is necessary…"
