How to Tighten Belt on Craftsman T110 Riding Mower

If you have a Craftsman T110 riding mower, you may find that the belt starts to loosen over time. This can be a frustrating problem, but fortunately it’s easy to fix. All you need to do is tighten the belt.

To do this, first Park your mower on a level surface and turn off the engine. Next, locate the two adjustment bolts on either side of the mower deck. These are usually located near the front of the deck.

Now, use a wrench to turn both bolts clockwise about 1/4 turn at a time. As you do this, you should see the slack in the belt start to disappear. Keep turning until the belt is tight enough that it doesn’t slip when you put pressure on it with your hand.

Once the belt is tight, double check that both adjustment bolts are turned to an equal degree. If they’re not, then one side of the deck will be higher than the other and your mower won’t cut evenly. Finally, restart your engine and test out your mower to make sure everything is working properly.

How Do You Tighten Up a Belt on a Craftsman Lawn Mower?

This knob is usually located near the front of the deck, on the left side. Once you have located the knob, turn it counterclockwise to loosen the belt. Next, locate the idler pulley beneath the mower deck.

The idler pulley is typically located on the right side of the deck, near the rear. Once you have located the idler pulley, push it down with your hand until there is enough slack in the belt to allow you to slip it off of the pulley. Now, take hold of one end ofthe belt and pull it tight.

You may need to use a pair of pliers to help get a good grip onthe belt. Once you have pulledthe belt tight, releasethe tensioner knob and allow it to snap back into place. This will help keepthe belt tight while you put everything back together.
