Harvest ground speed
Tractor correct moving speed is one of the factors that directly influences the machine production and
thetrituratedfodderquality.
Thespeedwillvaryduringaworkday,becauseitdependsofthesizeoftheculture,thetractor’spower
andlandconditions.So,theoperatormustdecidethebestspeedoftheharvester.
The machine must have the best productivity, in order to diminish the surplus of the material, without
compromisingitsfunctioning.
EnginespeedmustbesuchthatthePTOspeediscorrect:540rpm.
Check if your tractor has a decal, showing a table or a graphic scale that informs the speed for any
rotationineachgear.Ifyoudon’tfindit,checkyourtractor’smanual.
As an example see the decal below, for the tractor outputs at 540 rpm in the PTO with the engine at
1800rpm.
After you have defined the motor rotation, select the gear that provides proper speed to the harvest,
followingthisrule:
1-Forbulkycrops,tallerand/orforthintrituratedfodder,youshoulduselowspeeds.
2-Fornon-bulkycrops,shorterand/orforgrosstrituratedfodder,higherspeedsmaybeused.
