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. 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.
4.11 REAR ROLLERS
The machine can be equipped with various types of roller. The main ones are: Packer roller, Cage roller, Spiked roller.
Packer roller
▪
This is used to crumble the soil worked by the tines to a further degree and to guarantee a compact surface, optimum for
seeding. It has a bearing effect if the seed drill is mounted in a combined configuration. It is excellent for dry and hard soil.
Cage roller
▪
This is used for soil of medium consistency and when the degree of humidity is low. It prepares the soil for seeding but does
not compact the surface.
Spiked roller
▪
This is used for damp, clayey soils and in difficult situations. It does not compact the soil but levels it at the rear of the ma-
chine.

▪
Brake the tractor
▪
Lower the bearing stands
▪
Completely lower the machine to the ground
▪
Stop the tractor and engage the parking brake
▪
With the tractor stopped, its engine off and the components at a complete standstill, operate the levers of the hydraulic
circuit so as to relieve the pressure from inside the pipes. This will allow you to re-connect the quick couplings with greater
ease
▪
Disconnect the quick couplings
