After it hits something

The AAP says that if the mower strikes an object, stop, turn the mower off, and inspect it. If it is damaged, do not use it until it has been repaired.

If it will not start

LSU AgCenter says old gasoline will make an engine difficult or impossible to start in spring. Check the operator's manual before anything else.

Safety features come first

The CPSC says not to remove safety devices, and to check them often and repair or replace them if needed. Ohio State says not to disable safety features such as auto-clutches and shut-off switches.

Repairs and emissions

EPA says anyone who rebuilds an engine must generally restore it to its original configuration. It also says it never requires owners to retire their old engines.

Questions to ask a repair shop

Is the damage to the blade, the deck, or the safety controls? Are parts still made for this mower? Will the repair restore the original setup? Get the answers in writing before you decide.

FAQ

We have no source for one. Look at its condition and safety features, and see what the CPSC says about pre-standard mowers in our used mower guide.
The CPSC suggests asking, before you buy, whether you can do some maintenance yourself or whether the mower must go to a shop. Follow the manual.

General information only. Read the operator's manual before you mow. Keep children and pets indoors or well away from the area you mow, and never let a child ride on a mower as a passenger. The American Academy of Pediatrics says that, in general, children should be at least 12 years old to operate a walk-behind power mower safely and at least 16 to operate a riding mower safely. Before you clear, adjust, or service the blade area, turn the mower off, wait for the blade to stop, and disconnect the spark plug wire; on a battery or corded electric mower, follow the manual to disconnect its power. Refuel outdoors, only with the engine off and cool. Wear sturdy closed-toe shoes and eye and hearing protection. In an emergency, call 911.
