Husqvarna 175 AWD Checking the cutting unit’s parallelism, Replacing the cutting unit belts

Maintenance

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 kp/cm2/8.5 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.

Adjusting the parallelism of the cutting unit

1Remove the front hood and right-hand fender.

2Undo the nuts on the lift strut.

3Screw 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.

4Tighten the nuts after adjustment.

5On completion of the adjustment the unit’s parallelism should be re-checked.

6Fit the right-hand fender and the front hood.

Replacing the cutting unit belts

WARNING! Wear gloves to protect your

!hands when working with the blades.

There is a risk of crush injuries when working with the belt.

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

1Remove the cutting unit.

2Undo the bolt on the lift strut and the two screws on the cover. Lift the cover off the cutting unit.

3Loosen the spring (4) that tensions the V-belt and pry off the belt.

Simply reverse the procedure to fit the new belt.
