4

Place a set of bathroom scales under the cutting unit’s 
frame (front edge) so that it rests on the scales. If 
necessary a block can be placed between the frame and 
scales so that the support wheels do not bear any weight.

5

Adjust the unit’s ground pressure by screwing in or out the 
adjusting screws located behind the front wheels on both 
sides. The ground pressure should be between 12 and 15 
kg (26.5-33 lb).

Check the cutting unit’s parallelism as follows:

1

Check the air pressure in the tyres 60 kPa/0.6 kp/cm

2

/8.5 

PSI.

2

Place the machine on a flat surface.

3

Put the lifting lever in the mowing position.

4

Measure the distance between the ground and the front 
and rear edges of the cutting unit hood. The cutting unit 
should have a slight slant, with the rear edge 2-4 mm (1/
8”) higher than the front edge.

1

Remove the front hood and right-hand fender.

2

Undo the nuts on the lift strut.

3

Screw out (extend) the stay to raise the rear edge of the 
cover.

Screw in (shorten) the stay to lower the rear edge of the 
cover.

4

Tighten the nuts after adjustment.

5

On completion of the adjustment the unit’s parallelism 
should be re-checked.

6

Fit the right-hand fender and the front hood.

On these cutting units with collision-proof blades, the blades 
are driven by one V-belt. Do as follows to change the V-belt:

1

Remove the cutting unit.

2

Undo the bolt on the lift strut and the two screws on the 
cover. Lift the cover off the cutting unit.

3

Loosen the spring (4) that tensions the V-belt and pry off 
the belt.

Simply reverse the procedure to fit the new belt.
