If the tines clog, it is strictly forbidden to attempt to clean the machine whilst it is operating. First disengage the PTO, stop
the tractor and engage the parking brake. Wait until all moving parts have come to a complete standstill, then proceed with
the cleaning operations with the utmost care.

4.9 GEARBOX

The tine rotors can spin at various speeds, depending on the gear pairs mounted in the gearbox. It also allows the soil to be broken
up to various degrees depending on its nature, the amount of moisture it contains, the ground speed, etc.
Only use the pairs indicated in the table:
GEARBOXES - PTO 1000 rpm
A (PTO)
B
Trottle (rpm)
*optional
The faster the rotors spin, the more the soil is crumbled, but tractor power draw and blade wear will also be greater. You are advised
to use the lowest rotation speed able to work the soil in the required way. Carry out these simple operations in both gearboxes to
vary the speed of the rotors:
▪
▪
Remove the gears from the shafts
▪
Fit the required pairs of gears on to the shafts
▪
Fit back the cover and re-tighten the screws
