Briggs & Stratton RIDER 13, RIDER 11, RIDER 16 Checking and adjusting mower deck ground pressure

Reparation instructions

Checking and adjusting mower deck ground pressure

1

Check the tyre pressures (60 kPa/8,5 PSI).

Place a set of bathroom scales under the mower deck's frame (front edge) so that the deck rests on the scales.

2

Adjust the mowing deck's ground pressure with the adjuster nuts placed behind the front wheels on both sides of the ride-on mower. The ground pressure should be between 12 and 15 kg/26.5-33 lbs and the springs tensioned equally.

Checking and adjusting mower deck parallelism

1

Check the tyre pressures (60 kPa/8,5 PSI).

Place the ride-on mower on an even surface and measure the distance between the ground and the edge of the deck, at the front and rear of the cover. The cutting unit should slope forwards slightly so that the rear edge is 2-4 mm (1/8") higher than the front edge.
