EQUIPMENT
1) ROLLERS
The operator may choose to equip the
EL 142
with :
- either a packer roller (studs welded onto a cylinder),
- either a packer roller PK2 (studs welded onto a cylinder) (only for EL 142 - 3,00 m),
- either a maxipacker roller (rows of discontinuous studs welded on a large diameter cylinder),
- either a crumbler roller (welded tubes and removable bars)
- or a maxicrumbler roller (welded tubes).
The roller :
- adjusts and controls rotor working depth
- packs the ground behind the rotor to create an ideal seedbed
- increases crumbling efficiency by breaking down the clods
- improves ground levelling.
Adjusting the roller

Adjustment in direction of travel :
The roller can be placed in six different horizontal
positions so that the overhang is reduced to a mini-
mum in relation to the hood. This shift is carried out
with the 3 screws (C) on the multi-hole arms (A) and
plates (B) (photo 23).
Height adjustment :
The roller height is adjusted at (P) (photo 23).
To adjust, proceed as follows:
- Lift the machine behind the tractor,
- Place pin (T) in the hole corresponding to the required height (photo 23). Make sure that the same hole is used
on each side of the machine.
To limit the roller downward movement when manoeuvring on field end, a 2
nd
pin (T) may be ordered under part
number 517 070 00 (2 x) and be inserted in holes (O) of the adjustment plate (P) (photo 23). Do not restrain the
roller movement if the machine is equipped with a Venta seed drill resting on the roller arms.
To raise the roller completely out of work, lift the roller, then place the original pins (T) in holes (O).
Fitting of the adjustment sectors and roller arm mounting brackets
(photo 23)
Fit the adjustment sectors (P) on the side plates using 8 cup square bolts (I) (M12 x35) and 8 self-locking nuts (M
12) (screw heads positioned on the inner side of the side plates).
Fit the roller arm mounting brackets (K) on the side plates using 4 hexagonal screws (M) (M 12x35) and 4 self-
locking nuts (M 12).
