How to Adjust the Throttle of Your Self-Propelled Lawn Mower
The only real adjustment on these mowers is a bracket assembly used to secure both the operating and traction cables to the mower's handle. By loosening the bracket, you can slide the cables towards or away from the motor, which may increase or decrease the drive train traction and/or the throttle.
Step 1 - Release the Bracket
Loosen the bracket that secures the mower's cable to its handle. The bracket will be affixed with a nut and bolt, screw, or knob.
Step 2 - Make the Move
Carefully adjust the cable or cables, about a 1/2-inch away from the engine to increase traction, or towards the engine to decrease traction and tighten the bracket.
Step 3 - Take a Test Drive
Depress the starting bar and crank the engine. Slowly depress the drive train bar to test the mower's traction. If the mower is too fast or too slow, you may have to repeat the process numerous times until you achieve the desired response.
Always refer to the mower's owner manual before making adjustments and testing the mower. After adjusting the cables and before testing the mower for the first time, be prepared for an increased drive train response to avoid injury or property damage. Use extreme caution when operating a lawnmower. Keep hands and feet clear of the cutting deck at all times during operation to avoid severe injury. Wear the appropriate safety gear such as safety glasses, work boots, respirators, and work gloves when operating a lawnmower.
