Air filters

Starters and solenoids
Tell a bad solenoid from a bad starter before you order either.
Batteries
Size, charge, jump and replace the battery on a riding mower.
Switches and wiring
Ignition, seat, brake and PTO switches, fuses and wiring diagrams.

How we work
A test before every part
Guides start with a check you can run with a multimeter, a spark tester or a load test, so you don't replace a part that was never broken.
Matched to the engine, not just the mower
Plugs, filters and kits are set by the engine's model and type number. Each guide shows where to find yours.
Dated and re-checked
Every guide shows when it was last updated, and we fix mistakes as soon as we find them.
