Walker makes lawnmowers as well as a number of other lawn and yard related power equipment. Both Walker walk-behind and ride-upon mowers are designed to last for years, but, like all machines, can sometimes experience technical difficulties. Because of this, Walker has devised solutions to some of the most common problems facing Walker mowers.
GHS Full Horn
Many Walker mowers include a bag that holds the grass clippings after they have been cut from the ground. When this bag is full, the GHS full signal horn sounds to let the user know to stop and empty the bag. If this alarm does not sound when the bag is full, first check the horn itself by disconnecting the wires from the "Grass Pak" switch electric connector plug and connecting them directly to the battery as if they were jump leads. Next, set the ignition switch to "On" and move the clutch to "Engaged" position to activate the horn. If no sound is produced, the horn must be replaced, or if sound comes from the horn, replace the "Grass Pak" switch.
Occasionally a Walker mower, such as the professional grade MW series walk-behind mower, will experience a difficulty in cutting. Symptoms of this include rough edges of the cut or even an inability to cut at all. This is due to dull blades and can be solved by inspecting, and, if necessary, sharpening the blades. Inspect the blades by first disconnecting battery power from the mower to guard against injury. Next, raise the deck to the "Tilt-Up" position to gain visual access to the blades. Check the blades first for straightness. If a blade is more than 1/8 inch bent from its original position, it must be replaced for safety reasons. If the blades are straight, but worn or nicked, remove them by grasping the end of the blade with protective gloves and removing the nut, lock washer and flat washer. Once the blade has been removed, sharpen the blade edge with a grinder or hand file.
If the brake on a ride-upon mower, such as the MB series mower, seems too tight or does not effectively stop the mower, check and adjust the brake action by first loosening the brake band adjustment nut at the end of the brake lever. Adjust the pivot stop bolt until the brake pulley has an inch of travel between "Clutch Engaged" and "Clutch Disengaged." Refasten the brake band adjustment nut and test the brake. If still malfunctioning, try adjusting the pulley travel again.
