5.5 Driving the Mower Over a Curb
To climb a curb, first see the Safety Instructions section of this manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation In Reverse
• Operation In Forward Direction
Drive the mower in reverse at a 45 degree angle to the curb (with the left side of the mower closest to the
curb) until you are within an inch or two of the left-rear tire hitting the curb. Stop and then gradually bump
into the curb with that tire until it is just on top of the curb. If the tire slips even while lurching the mower into
the curb, then the curb is too high and you should use ramps or find another way. The mower should still be
at a 45 degree angle to the curb. Now, while maintaining the same angle to the curb, continue to back up
until the right-rear tire is close to the curb. Using the same technique lurch the right tire onto the curb. After
both wheels are on top of the curb, turn the mower counterclockwise and back up so the left caster wheel
comes over and last should be the right caster wheel as the mower is twisting to the left (counterclockwise).
The technique works the best if you try not to drive backwards at a near 90 degree angle to the curb but get
all of the wheels to go over while the mower is moving at least a 45 degree angle to the curb. To drive off a
curb, first try driving up onto it to make sure the curb is not too high. If the curb is not too high, drive the
right-front caster off first while driving toward the curb at a 45 degree angle (the curb should be to your right).
Then, maintain that 45 degree angle so the left caster goes over, then the right-rear wheel, then the left rear
wheel. Do NOT step off the mower during ANY maneuver.
5.5.1 Never Drive Straight Onto or Off A Curb
Never drive straight onto or off a curb. If you do the whole procedure at a very sharp angle it will tend to
minimize the contact of the mower deck with the curb and you will be able to more safely control the mower.
5.6 Mowing on Varying Terrain
See the Safety Instructions section of this manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation On Slopes
• Operation In Reverse
• Operation In Forward Direction
• Operation During Zero-Radius Turns
5.7 How to Adjust Neutral
Neutral refers to the mower movement when the engine is set to full throttle, parking brake is off, and the
control levers are in the neutral position. The mower should not
move forward or backward during this time. If the mower is moving
forward or rearward, the neutral setting must be adjusted. The
hydraulic pump has a Return-to-Neutral (RTN) device built into the
linkage of the pump. Before adjusting neutral, it is necessary to lift
the rear drive wheels off the ground using a jack and stands. To
make the adjustment, loosen the ¼” Allen bolt (A) and rotate the
RTN device on the pump corresponding to the wheel that needs
adjustment. If the right wheel turns in the neutral position, then the
right pump RTN needs to be adjusted. The RTN mechanism
should be rotated until the neutral position is found and then
retighten the ¼” allen bolt. Use care not to over tighten the allen
bolt. Repeat the procedure on the other pump if necessary.
