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 540 rpm
"Comer "
®
A (PTO)
B
Trottle (rpm)
GEARBOXES - PTO 1000 rpm
"Comer "
®
A (PTO)
B
Trottle (rpm)
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 screws that fix the rear cover of the gearbox (
▪
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
Make sure you use the right gears as gears of different pairs cannot be mounted.

4.10 REAR BAR

To level and crumble the soil to a greater degree, the harrow has a levelling bar positioned behind the tines. It can be adjusted in
height by means of crank screws (6 Fig. 1). It is advisable to start work with the bar in the upper position and to then adjust it to
the required setting. Make the adjustments by keeping the bar at the same distance from the soil as far as possible. Avoid using
the bar at depth as it could be damaged. Whenever the position of the rear roller must be changed, adjust again in order to skim
over the ground.
