10. Study of Chaff Cutter with 3D model and Drawings.

Chaff Cutter 3D Model
Chaff is hay cut into small pieces for feeding to livestock (Mohan D and Kumar A, 2004); it is a good
fodder, and at its best is cleanly and evenly cut, free of dust, of good colour and with a fresh aroma. Chaff
can be purchased from commercial chaff cutting mills.
Cutting chaff can be done by manually operated machine and electric operated one, As far as cutting by
manually operated machine is concerned. Traditionally for the operator it is done manually which is
physically demanding through it energy and postural requirements and is commonly regarded as source
of drudgery, many farmers associated with this task reported back, shoulder and wrist discomfort. It may
also cause clinical or anatomical disorders and may affect worker's health.

24. THE CHAFF CUTTER

The chaff box or cutter was a simple but ingenious device for cutting straw chaff, hay, and oats into
small pieces - before being mixed together with other forage and fed to horses and cattle. Apart from
being more economical than previous methods of feeding, this aided the animal's digestion and
prevented animals from rejecting any part of their food. Since the chaff box was made largely of wood
(usually ash) with only a small amount of ironwork, it cost relatively little to make and, as a result, few
farms, town or country stables were without one by the end of the eighteenth century.

There were two sizes, one of heavy construction which normally resided in the darkened corners of
barns or stables and another smaller model made of pine or similar wood which was portable.

The barn version typically comprised of an open-ended, three-sided wooden trough between 3 foot 6
inches and 4 feet (1067-1220 mm) in length, 9 to 12 inches (229-305 mm) wide and 9 to 12 inches deep,
mounted on either three or four legs approximately 22 inches (560 mm) high - giving an overall height of
about 34 inches (863 mm). The rear leg or legs were sometimes taller than the front to tilt the trough
forward to facilitate cutting. Both front legs of an early three-legged form were distinctly bow-shaped, a
characteristic of boxes from Kent and Sussex, while those with four legs were splayed.



Three-legged form in collection

25. To advance the bundle of hay or straw along the trough on all but the earliest models, a short-handled
dwarf or chaff fork with between four and six tines was provided, attached by chains to the front of the
box. These forks varied in width between 230-250 mm, depending on the inside dimensions of the
trough. The tines were about 120 mm long.

The front end was framed by a metal plate which looped over the top to provide a useful lifting handle.
Below this a large knife was hinged diagonally to a single or double sided arm which extended pivotally
from the base of one front leg and passed through the hollowed centre of the opposite leg. This allowed
the knife to be moved up and down in an oblique cutting action, rather like a modern office guillotine.
The plate stiffened the straw at the cutting edge as the sharpened blade passed close by.

The early chaff knives had a scimitar like shape with a curved blade broadening towards a cranked
wooden handle. Most ended their days with undulating edges. Scythe blades were often modified and
used. From the 1860's most factory produced replacement knives were made with straight cutting edges
varying in length between 20 and 34 inches with cranked or crosshead handles. At least nine large edge
tool manufacturers produced them in numbers including Isaac Nash & Sons - who continued to
advertise their best 'Crown' chaff knives in the 1930's. The cutting position on some could be adjusted
by moving the pivotal or hinge bolts into alternative holes drilled along the appropriate end of the knife
arm. When not in use the knife rested in an open-ended bracket or stop situated half way down the
opposite front leg. Knives were removed for thorough sharpening. Left-handed boxes were uncommon.

Beneath the box a treadle, hinged to the knife arm or the adjacent leg, operated a wood block clamp
situated inside the trough just behind the cutting edge. Its purpose was to compress the straw before
cutting. The clamp was held by a narrow length of iron bar which extended through vertical slits cut in
both sides. In pre-1800 form, this bar had looped ends from which ropes drew the clamp down on to the
straw. But, in order to move the straw forward after each cut, the clamp had to be continually pulled up
by hand using a piece of cord tied between the side and an iron staple located on top of the clamp. In a
later development the clamp was perforated by a spindle and held between an inverted bracket joined
to the treadle by a single hook or chain. By 1815 this type of linkage had been sprung by a length of
spring steel or wood bolted under the feed end which automatically returned the clamp to its upper pre-
compression position whenever the treadle was released. Some boxes, however, were equipped with a
less widespread form of recoil springing, the principle of which probably originated in Europe. It
comprised of two springy wooden poles fastened to the rear sides of the box, the overhanging ends of
which were tied to the ends of the clamp bar. Another more durable method of springing was provided
by a pair of side-mounted steel rods attached directly to the clamp spindle. These rods, under tension,
were slightly curved and fastened by brackets towards the feed end of the box.

26. Caspar Netscher, "The Chaff Cutter, Woman and Child", c1659, Philadelphia Museum of Art.


Working with a sprung clamp the trough was filled with straw and with the operator’s left hand holding
the curved handle of the dwarf fork, the tines embedded in the bundle, the operator pushed it forward
under the raised clamp to an inch or so past the cutting edge. Then with his left foot on the treadle, his
right hand holding the knife, he pressed the treadle down compacting the straw, raised the knife to a
high position and brought it down and across the face of the cutting edge slicing the protruding straw
into half inch (13 mm) long pieces. The foot was taken off the treadle, releasing the straw and the fork
used to push the bundle forward again to repeat the process. The operator sometimes stood with his
right foot on a small stool to apply more downward pressure on the treadle with his left foot. For two
man working, often a man and a boy, some boxes were equipped with a additional but smaller chaff fork
with only three tines situated and secured at the feed end. The assistant loaded the straw and moved it
along with this fork to the operator who continued as before. A stable riddle or baiting sieve was usually
placed below the cutting end to catch the cut chaff.

It required considerable dexterity to master the feed, treadle and cutting actions. In the hands of a
skilled person, however, it was said that between fifteen and twenty cuts could be made every minute
and that a man could produce forty bushels of chaff per day. But the implement could be unforgiving in
the hands of an inexperienced worker and there is little doubt that during its history its misuse caused
some personal injury. This was especially true of the earliest models which, like the portable version,
had no forks or clamps and were hand fed to the cutting edge. This is probably why farmhands in Kent
nicknamed it the 'Monkey Box' or 'Monkey Jumper'. In some places it was better known as a 'Chaff
Horse' or 'Cutter'. Originally, however, it was referred to as a 'Cutting Box' or a 'Chaff Engine' after the
earlier custom of naming anything remotely mechanical an 'Engine'.

In the early days some enterprising labourers and part-time thatchers learnt to use small portable chaff
boxes which they carried on their backs visiting town and country stables offering a chaff cutting service
for an agreed rate. The practice spread and it was not long before men were being paid comparatively
good wages, inviting Arthur Young in 1804 to comment that they "usually made much greater earnings
than the common pay per diem". In mid-18th century Hertfordshire the fee was said to be "one penny
per double bushel" but later reports put the amount at one penny per bushel cut. For an
"extraordinarily fine cut", Midland men received only three farthings for a heaped bushel (William
Marshall 1790). Being portable, the boxes were lightly constructed, about half the normal size and for
the most part were equipped only with a swivel knife of appropriate length. Consequently, they lacked
the safety features and other refinements found on later barn models. Some time afterwards an
improved version was introduced. As the demand for cut chaff increased, farmers found it more

27. beneficial to acquire the larger capacity boxes themselves and with slightly increased incentives (and
presumably some training), prevailed upon their ploughmen or stable lads to use them instead. The days
of the travelling 'Chaff Cutters' as they were once known became numbered and according to a census
of 1851 not more than 335 remained in employment. Excepting a few areas, the business came to an
end in England in the early 1900's.

Most of the chaff box's features had been established around the turn of the eighteenth century. By
then, however, it was beginning to compete with the new but relatively untried rotary chaff cutter
which had first appeared in small numbers in the 1770's.

Perhaps noting the early development of these rotary machines, attempts were made to improve the
box still further. One apparently successful model used in the Midlands incorporated a semi-automatic
feed arrangement where a sliding fork pulled by ropes wound around a small windlass pushed the straw
forward in the trough every time the treadle was released for the next cut. The windlass, located over
the front end, was fitted with a ratchet wheel and levers which controlled the forward movements.
When the trough required refilling the ratchet was disengaged, the fork slid backwards along a ledge to
be removed at the end of the box and then replaced on to new straw. As both hands were freed for
cutting a double-sided knife handle was provided. Probably referring to this box in 1790 William
Marshall thought it was "somewhat complex and fitter for a man who makes business of straw cutting
than for a farmer's servant". Another innovation from Norfolk employed a fluted feed roller through
which straw was compressed before cutting. There were also other less well-disseminated variations.

Despite, these developments, which peaked around the 1830's, the chaff boxes became increasingly
displaced by the faster and then more efficient rotary cutters with their automated feed systems. Even
so, they remained in use, especially on smaller farms and stables in England and Wales until the 1930's,
becoming, in some instances, a stand-by for mechanical failures. The Welsh found them convenient for
chopping up gorse for fodder and several were brought out of retirement during World War II. A few
were also retained by thatchers for cutting reeds to size. Their longevity was probably due to their cheap
and simplistic construction, readily undertaken by any competent craftsman especially when viewed
against the expense of the new machines costing at least four to five times as much. Distribution was
principally confined to the Southern Counties, parts of the Midlands and Wales. Apart from stagecoach
stations there is little evidence of chaff box use in Northern England or in Scotland before the
widespread adoption of the rotary chaff cutter.

The business of chaff cutting began on the Continent long before it occurred in England. As far back as
the late 15th or early 16th century, chaff cutters were plying their trade in central Europe where the box

28. may have originated. A model shown in the Augsburg drawing of 1524 gradually evolved as its use
spread through Germany, and, in particular, Holland and Belgium from where an early example is
thought to have been introduced into England during the 17th century, quite possibly by Flemish
immigrants to Kent.

Earliest known depiction of a chaff-cutter: woodcut from Augsburg, 1524


Despite being aware for 200 years of the European method of feeding horses with finely chopped straw
"cut fit by an instrument of purpose" (Blundeville 1565) no public interest was shown in the subject until
the mid-18th century. An early indication of its presence here came with John Lewis's book, "The History
and Antiquities, Ecclesiastical and Civil, of the Isle of Tenet in Kent" of 1723. He described how "oats,
beans and peas in the sheaths unthreshed" were "cut in a box with a cutter made for that purpose
which was pretty hard work". In a second edition published 13 years later he included a drawing of a
three-legged "Cutting Box to cut horse meat in" – meat in this case meaning fodder. The free-standing
model shown comprised of nothing more than a swivelling knife attached to a wooden trough on legs,
but like the Augsburg example its significance lay in its unique cutting action. In 1745 William Ellis's book
"Agriculture Improved" appeared. The author, given to some salesmanship, referred to a 'famous' and
'profitable engine' which he claimed "may be so worked as to cut sixty single or thirty double bushels of
chaff in one day by one man". He also states the engine "serves to employ servants in rainy days within
doors when they cannot work without". Indeed, according to Ellis, the engine was "kept by most great
farmers in Southern England" and he offered to supply the implement to readers at a cost of one guinea
plus carriage charges. Unfortunately, Ellis did not provide a drawing, but before his death in 1758 he
wrote of the chaff cutter's way of placing a large handful of oat straw and cavings of wheat "at the
bottom of a long cutting box which being pulled all together forward to the knife, by a forked
instrument", the latter an early reference to the use of a dwarf fork which later became widespread.

A letter from an anonymous correspondent in Canterbury published in the journal "Museum Rusticum
et Commerciale" of 1764 recommended the use of a 'cutting box' for preparing feed and accompanied it
with a drawing and description which though a right-handed version was virtually identical to Lewis's
illustration 28 years earlier. Two respondents, Thomas Comber and James Crockett, suggested
improvements but most were either impractical or unworkable. By this time, however, the Continentals
had already introduced a number of modifications some pre-dating the early English boxes by 100 years
or more. Almost certainly some of these developments crossed the English Channel during this period
and were used or adapted to suit local requirements.

29. The chaff box was the forerunner of all straw cutting machines and undoubtedly one of the most
creative inventions in pre-mechanical agriculture. Although comparatively short-lived in Britain, the
basic design had lasted for over four hundred years in Europe. Being mainly of wood only a small
number have survived the ravages of time intact. Some examples, however, may still be seen at various
rural life museums including Avebury, Cobtree, Colchester, Gressenhall, Oakham and Reading (see links
page). Most of these would have been constructed during the nineteenth century.


Peter Charles Dorrington collected and restored over 750 antique farm tools between 1985 and 2001. Most of these
tools were agricultural hand implements and fenland tools that were used in England, Wales and Scotland, dating
from about 1600 to 1940, for example: "chaff cutters", "flails", scythes", "dibbers" and "breast ploughs". Photographs
of roughly half of the tools that are still in the collection are included here. Information and notes on some of the tools
are also included.
In pre-industrial societies, throughout the world, most people worked as agricultural labourers. Indeed many of the
types of hand farm tools on this website might have been used by your own ancestors...
