This step-by-step riding mower repair guide explains how to replace the flywheel key on a riding lawn mower or lawn tractor. The flywheel key is a small rectangular piece of metal that keeps the crankshaft and flywheel aligned when you tighten the flywheel nut. To protect expensive engine components from damage, the flywheel key shears off if the mower blade hits an object hard enough to make the flywheel slip out of alignment with the crankshaft. Replace a broken or sheared flywheel key using a manufacturer-approved replacement part. More on here: https://pickbestlawnmower.com/lawn-sprinkler/
This DIY riding mower repair guide gives step-by-step instructions for replacing the seat on a riding lawn mower. For safety, a switch in the riding mower seat allows the mower to run only when it senses that someone is on the seat. If the seat is cracked or the foam cushioning inside the seat is missing or broken down, the seat switch might not engage when you’re in the seat. In that case, the engine shuts off when you release the brake. To fix the problem, replace the seat with a manufacturer-approved replacement part.
This DIY riding mower repair guide gives step-by-step instructions for replacing the brake interlock switch on a riding lawn mower. When working correctly, this safety switch keeps the engine from starting if your foot isn’t pressing down on the brake or if the parking brake isn’t set. If the switch breaks, it won’t let current reach the starter solenoid coil even though the brake is on, and the engine won’t start. If the solenoid doesn’t click when you turn the ignition key, the brake interlock switch is most likely at fault. Watch this lawn tractor troubleshooting video to learn how to test the starting system and brake interlock switch. Replace the brake interlock switch with a manufacturer-approved replacement part.
