Fortilling,thedepth stakemustbeloweredandthe
wheelmustbe raised,Figure4-4.
By increasingthedepthof thedepth stake,theforward
speedof the machineis reducedandthe workingdepth
is increased.Whenthe depthstakeis raised,the working
depthof the machineis reducedandthe forwardspeed
is increased.The workingdepthof the machinemay
bepredeterminedby settingthedepthstakeso thatthe
wheelsareaboutfourinchesfromthe groundwhenthe
tinesanddepthstakearerestingonthe ground.This
settingwill permitaworkingdepthof about fourinches.
Whenpresettingthe workingdepth,the handlesshould

Thetiller will belowerwhenthe tinesand depthstake

Handle Pressure
Furthercontrolof tillingdepthandtravelspeedcan be
obtainedby variationof pressureonthe handles.
A downwardpressureon the handleswill reducethe
workingdepthandincreasethe forwardspeed.An
upwardpressureon the handleswill increasethe
workingdepthandreducethe forwardspeed.
Thetypeof soilandworkingconditionswill determinethe
actualsettingof the depthstakeandthe handlepressure
required.
Cultivating
Forcultivating,a twoto threeinchdepth isdesirable.The
throttleshouldbe setto controlforwardmovementto a
slowwalkingspeed.Withthe outertinesinstalled,the
workingwidthof the machineis22 or24inches.
Forcultivation,thismaybereducedto 13inchesby
removingthe outertines,referto the AdjustmentSection.
Whenlayingout plant rows,be sureto allowenough
