Here are a few tips: 1. The belt should be snug but not tight when you first put it on.

You should be able to depress the belt about an inch with your thumb. As the belt stretches with use, it will loosen up slightly, so don’t worry if it’s a little bit loose after a few uses. 2. If the belt starts to slip or doesn’t seem to be turning the blades as well as usual, it’s time to tighten it up.

Use a wrench to tighten the bolts that hold the deck in place until the belt is snug again. 3. Avoid overtightening the bolts or you could strip them or damage the deck itself. Just turn them until they’re snug – no need to go crazy!

4. Check your mower deck regularly for any damage or wear and tear that could cause problems down the line. Replace worn out belts promptly to avoid any issues while mowing your lawn!
