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.
Types of chaff cutter:
1. Chute-Fed Chaff Cutter - A chaff cutter in which the feeding of the fodder crop is done through a chute.
2. Conveyor Fed Chaff Cutter - A chaff cutter in which the feeding of the fodder crop is done through a
conveyor.
3. Let-Fall Type - A chaff cutter in which the cut fodder is dropped down to the bottom of the chaff cutter.
4. Throw Away Type - A chaff cutter in which the cut fodder is thrown away to the front ward of the chaff
cutter.
5. Blow-Up Type - A chaff cutter in which the cut fodder is blown up through the blow-up pipe.
6. Fly Wheel Type - A chaff cutter havi.ng rotating fly wheel with blades.
7. Cylinder Type - A chaff cutter the cutting mechanism which consists of a rotating cutting cylinder.
Types on the basis of cutting mechanism:
a) Fly wheel type, and b) CyIinder type.
On the basis of cut-chaff dropping position, the chaff cutter shall be of following types:
a) Let-fall type, b) Throw-away type, and c) Blow-up type.

Components of Chaff Cutter:
1. Flywheel
The flywheel is made of cast iron or Steel For mounting blades and storing energy for cutting the chaff
during operation. The flywheel should be heavy and balanced for cutting of chaff with efficiency. A
flywheel of 900 mm to 1350 mm diameter shall be provided. The flywheel shall have two arms. Each arm
shall be provided with one square hole for fixing the handle; three holes for fixing the blade and six
tapped holes for fixing the bolts for blade setting adjustment. At the centre of the flywheel, a circular hole
shall be provided for connecting it to the main shaft. A hole of 10 mm diameter shall be made in the rim of
the flywheel parallel to the direction of the hub hole. The weight of the flywheel shall not be less than 24
kg.
Chaff cutter shall be provided with a linchpin with the chain to lock the chaff cutter flywheel when it is not
required to be operated. This shall be fixed on the flywheel main gear shaft at the end so as to restrict the
movement of the system. This is especially needed to lock the movement of the chaff cutter blades in
order to avoid injuries due to accidental rotation when chaff cutter is not in use. The linchpin shall be
fastett%dto the body of chaff cutter with the help of the chain. A bolt shall also be fitted in both the holes
(hole of leg and hole of flywheel rim) and tightened with a nut.
2. Feed Roller: Feed rollers are provided for dragging crop inside the cutting housing for preventing
hazards to the human being. A guard should be provided on the rollers and cutting housing for avoiding
accidents during feeding the crop.

24. THE CHAFF CUTTER
The chaff box or cutterwas a simple butingeniousdevice forcuttingstraw chaff,hay,and oatsinto
small pieces - before beingmixedtogetherwithotherforage andfedtohorsesandcattle.Apart from
beingmore economical thanpreviousmethodsof feeding,thisaidedthe animal'sdigestionand
preventedanimalsfromrejectinganypartof theirfood.Since the chaff box wasmade largelyof wood
(usuallyash) withonlyasmall amountof ironwork,itcostrelativelylittle tomake and,as a result,few
farms,townor country stableswere withoutone bythe endof the eighteenthcentury.
There were twosizes,one of heavyconstructionwhichnormallyresidedinthe darkenedcornersof

The barn versiontypicallycomprisedof anopen-ended,three-sidedwoodentroughbetween3foot6

dwarf or chaff forkwithbetweenfourandsix tineswasprovided,attachedbychainstothe frontof the

In the earlydayssome enterprisinglabourersandpart-timethatcherslearnttouse small portable chaff

of 1851 notmore than 335 remainedinemployment.Exceptingafew areas,the businesscame toan
endinEnglandin the early1900's.
Most of the chaff box'sfeatureshadbeenestablishedaroundthe turnof the eighteenthcentury.By
then,however,itwasbeginningtocompete withthe new butrelativelyuntriedrotarychaff cutter
whichhad firstappearedinsmall numbersinthe 1770's.
Perhapsnotingthe earlydevelopmentof these rotarymachines,attemptsweremade toimprove the
box still further.One apparentlysuccessful model usedinthe Midlandsincorporatedasemi-automatic

Despite,these developments,whichpeakedaroundthe 1830's, the chaff boxesbecame increasingly

The businessof chaff cuttingbeganonthe Continentlongbefore itoccurredinEngland.Asfar back as
the late 15th or early16th century,chaff cutterswere plyingtheirtrade incentral Europe where the box

spreadthroughGermany,and,in particular,HollandandBelgiumfromwhere anearlyexample is
thoughtto have beenintroducedintoEnglandduringthe 17thcentury,quite possiblybyFlemish
immigrantstoKent.
Earliestknowndepictionof achaff-cutter:woodcutfromAugsburg,1524
Despite beingaware for200 yearsof the Europeanmethodof feedinghorseswithfinely choppedstraw
"cut fitby an instrumentof purpose"(Blundeville 1565) no publicinterestwasshowninthe subjectuntil
the mid-18thcentury.Anearlyindicationof itspresence here came withJohnLewis'sbook,"The History
and Antiquities,Ecclesiastical andCivil,of the Isle of TenetinKent"of 1723. He describedhow "oats,
beansand peasinthe sheathsunthreshed"were"cutina box witha cutter made for that purpose
whichwasprettyhard work".In a secondeditionpublished13yearslaterhe includedadrawingof a
three-legged"CuttingBox tocut horse meatin" – meatinthis case meaningfodder.The free-standing
model showncomprisedof nothingmore thana swivellingknifeattachedtoa woodentroughonlegs,
but like the Augsburgexample itssignificance layinitsunique cuttingaction.In1745 WilliamEllis'sbook
"Agriculture Improved"appeared.The author,giventosome salesmanship,referredtoa'famous'and
'profitable engine'whichhe claimed"maybe soworkedasto cut sixtysingle orthirtydouble bushelsof
chaff in one dayby one man".He alsostatesthe engine "servestoemployservantsinrainydayswithin
doorswhentheycannotwork without".Indeed,accordingtoEllis,the engine was"keptbymostgreat
farmersinSouthernEngland" andhe offeredtosupplythe implementtoreadersat a cost of one guinea
pluscarriage charges.Unfortunately,Ellisdidnotprovideadrawing,butbefore hisdeathin1758 he
wrote of the chaff cutter'sway of placinga large handful of oat straw andcavingsof wheat"at the
bottomof a longcuttingbox whichbeingpulledall togetherforwardtothe knife,byaforked
instrument",the latteranearlyreference tothe use of a dwarf forkwhichlaterbecame widespread.
A letterfromananonymouscorrespondentinCanterburypublishedinthe journal "MuseumRusticum
et Commerciale"of 1764 recommendedthe use of a'cuttingbox' forpreparingfeedandaccompaniedit
witha drawingand descriptionwhichthougharight-handedversionwasvirtuallyidentical to Lewis's
illustration28yearsearlier.Tworespondents,ThomasComberandJamesCrockett,suggested
improvementsbutmostwere eitherimpractical orunworkable.Bythistime,however,the Continentals
had alreadyintroducedanumberof modificationssome pre-datingthe earlyEnglishboxesby100 years
or more.Almostcertainlysome of these developmentscrossedthe EnglishChannel duringthisperiod
and were usedoradaptedto suitlocal requirements.

29. The chaff box wasthe forerunnerof all straw cutting machinesandundoubtedlyone of the most
creative inventionsinpre-mechanical agriculture.Althoughcomparativelyshort-livedinBritain,the
basicdesignhadlastedforoverfour hundredyearsinEurope.Beingmainlyof woodonlyasmall
numberhave survivedthe ravagesof time intact.Some examples,however,maystill be seenatvarious
rural life museumsincludingAvebury,Cobtree,Colchester,Gressenhall,OakhamandReading(seelinks
page).Most of these wouldhave beenconstructedduringthe nineteenthcentury.
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 thatwere used in England,Wales and Scotland,dating
from about 1600 to 1940,for example:"chaff cutters","flails", scythes","dibbers"and "breastploughs".Photographs
of roughly half of the tools that are still in the collection are included here.Information and notes on some ofthe tools
are also included.
In pre-industrial societies,throughoutthe world,mostpeople worked as agricultural labourers.Indeed manyof the
types of hand farm tools on this website mighthave been used by your own ancestors...
