LELY POLYMAT 300W - Mounting Behind the Tractor

- Adjust the chain lenght. If the chains are shortened or the
adjustment strips A (fig. 9) are secured higher up, the
POLYMAT will follow the LELYTERRA sooner when the
combination is lifted. The tractor’s hydraulic lift can then
be adjusted lower.
Throughout the operation, the chains are not allowed to be
tightened. Make sure that their free movement is sufficient.
