Replacing the blades on your lawn tractor is an important part of maintaining your lawn. Dull or damaged blades can tear the grass instead of cutting it, which can lead to a brown, unhealthy lawn. Replacing the blades is a relatively simple task that can be completed in about 30 minutes.
To replace the blades on your lawn tractor, you will need a new set of blades, a wrench, and a pair of gloves. First, park the lawn tractor on a level surface and engage the parking brake. Then, locate the blade spindles under the deck of the tractor. There will be two spindles, one on each side of the deck. Using the wrench, loosen the nuts that hold the blades in place. Once the nuts are loose, you can remove the blades from the spindles.
