For effective lawn care, you need a lawn mower that’s in good shape. When there are minor problems with your equipment, you can often visit a local hardware or garden supply store for repairs. But sometimes—through everyday wear and tear, a jammed part that causes damage, or excessive rust—a repair would prove more costly than it's worth and you're better off buying a replacement. The list below will help you decide when it’s time to invest in new equipment.

When to Replace Your Lawn Mower

1. You Hear Shaking & Knocking

The crankshaft is the component that transfers the power of the engine to the blades. When it's bent—usually after striking a hard object—the blades begin to spin at an angle and may scrape on other mower components. They likely won't cut correctly and the mower may vibrate, shudder, or make a repetitive knocking noise.

2. Engine Damage

An engine can be damaged by running on too little oil, using the wrong kind of fuel, or undergoing simple wear and tear. If the engine is the problem, the engine may run inconsistently, make unusual noises, or not start at all. Engine repairs can cost almost as much as a new lawn mower.

3. Severe Rust

Check your mower for rust every time you use it. If you find any, it's important to remove it and protect the area with paint or a rust-resistant coating. Rust left too long can eat through the deck of the mower—often the most expensive part of the machine.
