Using the cage roller
The cage roller is intended to crumble clods and even out the ridges left by the s-tines of the harrow.
The weighing of the cage roller is adjusted with a crank. Turning the crank clockwise increases the
weighing of the roller and turning the crank counter-clockwise decreases it ( point 1). Normally there
should be at least 50 mm of visible thread of the adjustment crank below the nut. Weighing can be
increased on hard soils to achieve more effective tillage and leveling.

Front support wheel ( T1000 – T1500 only)
Support wheel stabilize the movements of the side wings. The weighing is adjusted so that the wheel
rests lightly on the ground when tillage is performed to working depth. The requirement is that the
wheel can be turned manually.
Excessive weighing raises the front end of the harrow and stresses the support wheel. If the weighing is
not strong enough, the wheel does not touch the ground and thus it does not support the moving of
the harrow.
