Lawn Mower Tune-Up vs Replacement: Spring Decision

As the last of the snow melts, a familiar spring ritual begins for millions of homeowners: pulling the lawn mower from the back of the shed. But for mowers entering their 7th, 8th, or 10th season, this often leads to a frustrating tug-of-war with a sputtering engine. With the average gas-powered walk-behind mower lasting 8-10 years, that spring struggle is a critical decision point: invest in a tune-up and potential repairs, or is it time to replace the machine entirely?

This guide is for homeowners with a gas-powered, walk-behind mower that is 5-10 years old and showing signs of age. If you're facing a non-starting engine, rough performance, or simply wondering if this is the year to upgrade to a newer gas or battery-electric model, you are in the right place. We will provide a data-driven framework for making the most cost-effective decision.

Before diving into specific costs, it's essential to understand the guiding principle for most appliance repairs: the 50% rule. This rule states that if the cost of a repair exceeds 50% of the cost of a new, comparable replacement, you should replace the item. For a lawn mower, this provides a clear financial test.
