Troy Bilt lawn mowers are known for their excellent quality, but even the best mowers require regular maintenance. You can always take your mower in for professional service, but in most cases, the tasks aren't too difficult.

Troy Bilt Mower Replacement Blades

When your mower's blades are dull, you'll most likely notice that your lawn simply doesn't look it's best. It's common to notice the tips of the grass blades turning brown shortly after mowing. This happens because the grass is ripped and torn instead of being cleanly sliced. Even worse, the poor cut makes your lawn prone to disease.

You may even notice that your grass has an uneven cut.

But fortunately, dull blades can be sharpened. The process isn't too difficult to do yourself, or you can take your mower to a professional and have them do it for you. Although, if you don't want to deal with it at all, or if your blades have been sharpened to a point where they need to be replaced, you can purchase new ones.

Another concern besides the blades becoming dull, is they could dent or bend. If you run over loose rocks or run over concrete paving, or hit tree roots, you could damage the mowers blades beyond repair. When this happens, your only choice is to purchase a new set of blades.

Troy Bilt lawn mower replacement blades are very affordable and easy to install. Once you determine the correct blade that matches your mower model, you may want to consider keeping an extra one hand so you can easily swap them out if necessary.

As with all specific parts, you should consult your user manual to find the exact replacement part number. But you should be able identify the type by simply removing the old filter.

If you own a larger Troy Bilt model, such as the TB370, you'll find it uses both the oval style and flat cartridge air filters.

You can clean the air filters, however we recommend replacing them instead. This is because excessive cleaning and duty cycles can reduce the air filter's efficiency and lead to reduced airflow, or increased particles in the air intake. In other words, they won't be as effective.
