3. HITCHING UP
HITCHING TRACTOR UP TO UNI-PRESS
NOTE:- When the Uni-press is parked, it SHOULD ideally be left in the unfolded, i.e. work,
position for stability, safety and ease of access for maintenance
1. Couple the six hydraulic hoses to the tractor ensuring that the two wing hoses are
together, the two drawbar cylinder hoses are together and the two levelling board hoses
are together.
2. Connect the tractor to the drawbar using the hydraulics to raise or lower the height of the
shackle.
3. Carefully operate the hydraulics to lower the drawbar and tilt the Uni-press onto the road
transport wheels. Fully extend the drawbar cylinders.
4. This allows the levelling boards to be fully raised so that when the Uni-press is folded the
levelling boards do not protrude beyond the 3m transport width. Fully raise the levelling
boards.
5. Ensure that the wing strap is fitted to tie the two wing sections together.
6. Ensure that parking stands are locked up into the gangs.
HITCHING A DISC HARROW UP TO THE UNI-PRESS
NOTE:- When the Uni-press is parked, it SHOULD ideally be left in the unfolded, i.e. work,
position.
1. Remove the transport straps from the disc harrow, exercise great CARE when extending
the axle cylinder.
2. Reverse the disc harrow up to the Uni-press drawbar ensuring that the two drawbars are
aligned allowing a slight clearance to enable the machines to be coupled together.
3. Lower the disc harrow to the ground.
4. Connect the four hydraulic hoses from the Uni-press into the disc harrow rear outlets
ensuring that the two wing hoses are together and the two drawbar cylinder hoses are
together. Ensure that the folding circuits and lift drawbar circuits are coupled correctly.
5. Raise the Uni-press drawbar above the disc drawbar (200mm approx.).
6. Close the two shut off taps on the Uni-press drawbar cylinder.
7. Raise the disc harrow to the same height as the Uni-press drawbar then reverse the disc
harrow to couple the two machines together.
