WARNING 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 Instruction Manual 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. To make the adjustment, loosen the ¼” allen bolt
and rotate the RTN device until the neutral position is found and
then retighten the ¼” allen bolt. Use care not to over tighten the
allen bolt.
5.8 Changing the Speed/Sensitivity Adjustment
The WZK has three Speed/Sensitivity settings. The settings are changed by removing the control rod at the
control levers and inserting into the alternate holes.
The controls are initially set with the Speed/ Sensitivity adjustment in the 12 MPH position. With operators
not completely familiar with the mower operation the operator may desire to leave the controls in the factory
setting or move to the slow hole position until becoming familiar with the operation. The faster setting has a
corresponding increase in the sensitivity of the controls. In other words, a given amount of movement of the
control levers will cause about a 10-15% increase in the ground speed making the controls more sensitive.
After stopping the engine, the adjustment is made by removing rod ends connected to the control rods from
the current holes in the control levers and reinstalling them into the alternate holes. The holes closest to the
operators position are for the faster, more sensitive setting and the holes farthest from the operators position
are the slower, less sensitive setting. You must then perform the Tracking Adjustment described below.
