Checking and adjustment of the cutting unit’s ground pressure

To achieve the best cutting results the cutting unit should follow the underlying surface without pressing too hard against it.

Pressure is adjusted using a screw and spring on each side of the Rider.

1Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.

2Place the machine on a flat surface.

3Put the lifting lever in the mowing position.

4Place 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.

5Adjust 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).

Checking the cutting unit’s parallelism

Check the cutting unit’s parallelism as follows:

1Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.

2Place the machine on a flat surface.

3Put the lifting lever in the mowing position.

4Measure 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.
