manualformoreinformation.
PTORotation
5.2 - Harvest ground speed
Tractor correct moving speed is one of the factors that directly influences the machine
productionandthetrituratedfodderquality.
The speed will vary during a work day, because it depends of the size of the culture, the
tractor’s power and the land conditions, so, the operator must decide the best speed of the
harvester.
The machine must have the best productivity, in order to diminish the surplus of the material,
