On each belt unit, two tracking rollers are located very close to the point of tine engagement so the pick-up is guided perfectly over bumps in the ground. They track the ground over almost the full working width. This ensures smooth operation even on uneven and soft ground.
Compared to skids, the rollers are wear-resistant. In addition, there is no risk of damaging the sward on damp ground.
Additional skid protection
Skids are also attached to the outside of each belt unit. These are positioned slightly higher than the tracking rollers. They only come into contact with the ground in exceptional situations to prevent forage contamination and damage to the pick-up on the edge of embankments.
The working height is set by the position of the tracking rollers. A hand crank for adjusting the working height is fitted on the back of each of the two belt units.
To minimise forage contamination, the tines should ideally pass at least 3 cm above the ground.
