2.3 Setting The Cutting Height And Ground Clearance
Remove the Power Pack before making any adjustments. The Robomower has two basic
adjustments, cutting height and ground clearance. The cutting height adjustment is located at the
front wheel and is controlled by rotating the front wheel hub in or out, which effectively causes the
front wheel to be raised or lowered. See Figure 2.6.
The ground height adjustment is located in the Power Pack compartment of the mower. See
Figure 2.7. It has two positions, upper and lower. (RL550 Europe has three; upper, lower and
middle) The lower position (closest to the bottom of the Power Pack compartment) provides the
highest level of ground clearance while the upper position (farthest from the bottom of the Power
Pack compartment) provides the least amount of ground clearance. See Figure 2.8.
Severe injury is possible. Always remove the Power Pack when attempting
to adjust the height of cut or otherwise lifting the mower off the ground.
Never lift the mower or attempt to adjust the cutting height during
operation. Blades are very sharp and severe cuts or lacerations are
possible. When working around or near the blades always wear heavy
gloves.
