Perfect for my use.Could have better pictures,but otherwise perfect ;)

Checking and Adjusting the Cutting Unitâs Ground Pressure
In order to achieve the best mowing result the cutting unit should follow the ground without touching it too heavily. The pressure is adjusted using a screw on each side of the Rider. 1. Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI. 2. Place the Rider on a flat surface. 3. Put the lifting lever in the mowing position. 4. Place a set of bathroom scales under the cutting unitâs frame (on the front edge) so that the unit rests on the scales. If necessary a block can be placed between the frame and the scales so that the anti-scalp rollers do not support any weight. 5. Adjust the cutting unitâs ground pressure by screwing the adjuster screws, which are located behind the front wheels on both sides, in or out. The ground pressure should be between 12 and 15 kg (26.5-33 lb). IMPORTANT INFORMATION When changing the cutting unit, you must readjust the parallelism and cutting height.
1. Place the Rider on a flat surface. 2. Loosen the nut on the height adjustment strut. 3. Measure the distance between the ground and cutting unitâs edge at the front of the cover. The cutting unit should have a slight slant, with the rear edge 2-4 mm (1/8") higher than the front edge. The distance between the front edge and the ground should be: â¢ 40 mm for Combi 94 and Combi 103 â¢ 35 mm for Combi 112. 4. Tighten the nut. 5. Check that the parallelism has not changed. If so, the parallelism must be readjusted. 6. Check and if necessary adjust the cutting unitâs ground pressure. 7. Fit the front cover.
