Drawing 3: Adjusting the height of cut.
In order to change the height of cut from 40mm to 44mm, the 8mm spacer ring should be substituted with a 12mm
spacer, and in order to achieve the 32 mm height of cut, the spacer ring should be disassembled.
To make height adjustment the following must be done:
1.
Position the mower to the transport position and lift it to the upper position.
2. Set the tractor’s handbrake and disengage the tractor’s engine.
3. Secure the mower from falling with a chain and an additional support placed under one of the stump jumper
disks.
4. Unscrew the bolts M12x25 (Position 1 in Drawing 3) and disassemble the stump jumper (Position 2 in Drawing
3).
5. Unscrew the resistance disc bolts (Position 3 in Drawing 3) M12x30 and take it off.
6. Adjust the cut height and assemble it in the reversed order.
7. Perform the adjustment in the other stump jumper disc repositioning the support.
