ROLLERS
According to the user’s choice, the rotary power harrows can be equipped with :
- either 2 maxicrumbler rollers (with welded tubes) (only for HR 6002 DR / 6002 DR - S),
- either 2 packer rollers (rows of continuous studs welded on a cylinder),
- or 2 maxipacker rollers (rows of discontinuous studs welded on a large diameter cylinder).
.
The roller is an essential element of the harrow and has four main functions :
- to set and control the working depth of the machine,
- to pack the tilth evenly behind the rotors to create an optimum seedbed,
- to increase seedbed crumbling and clod break-up,
The roller is also used as a protection device at the rear of the machine. It must never be
removed.
To raise the roller completely out of work to reduce for example the transport width when the machine is folded, lift
the roller, then place pin (T) in hole (O) (photo 9).
- to improve seedbed levelling.
The roller can be adjusted horizontally in 2 different
positions (E) and (E’) (photo 9). Position (E’) must be
used when a levelling bar is fitted to the rear of the
trough (see page 27, photo 25).
The roller height is adjusted at (P) (photo 9). To adjust,
proceed as follows :
- Lift the machine behind the tractor,
- Place pin (T) in the hole corresponding to the
required height (photo 9). Make sure that the same
hole is used on each side of the half-machines.
