13.1 CHANGING / REPLACING THE KNIVES
If the knives are worn out or another knife thickness is required, the knives should be
changed. This is done as follows
(see Figure 11)
:
Make sure that the Verti-Cut is blocked well and cannot move on its own
accord!
Make sure that the PTO is detached from the Verti-Cut!
1. Remove all nuts (1) and the safety cap (2).
2. Remove the bottom cover (3).
3. Loosen the tension of the V-belts (4) and remove the V-belts from the bottom
pulley (5).
4. Lift the machine and loosen the centre bearing (6) together with the spacers (7)
by removing the fastening bolts.
Make sure that the Verti-Cut is blocked well and cannot move on its own

5. Lower the machine onto the ground and remove the bolts from the bearings (8)
on both sides of the machine.
6. Lift the machine and remove the rotor axle (9).
Watch out: the knives may be sharp!
7. Remove the nut (10) from the rotor axle (9) and remove the knives (11), centre
bushes (12), end bush (13) and the centre bearing (6).
8. Reconstruct the rotor axle by sliding the knives in a spiral and stepped way onto
the axle.
Take the following into account: the centre bearing (6) is at distance A (= 679mm or
26.7”) and the welded side of the bearing house must face the side of the rotor axle nut.
9. At the end, place end bush (13) and nut (10) back and tighten the nut.
10. Place the rotor axle (9) back in the machine.
11. Mount the bearings (8) on both sides of the machine and tighten the nuts.
12. Attach the centre bearing (6) together with the spacers (7) to the frame and
tighten the nuts.
13. Put the V-belts (4) around the bottom pulley (5).
14. Tighten the V-belts of the Verti-Cut as described in Chapter 13.0.
