Replacing a Cub Cadet XT1 LT42 belt is a critical repair – the deck belt allows the mower's moving parts to operate correctly. It's highly unsafe to try to use a lawnmower without a fully functional deck belt. If your mower's deck belt requires replacement, you may hear a loud screeching sound, especially when you first start the mower. Replacing a Cub Cadet XT1 LT42 isn't a complex repair, but it does necessitate disassembly of the mower deck.


Cub Cadet Mower Deck Belt Diagram and Disassembly

You must put the deck back together correctly to avoid irreparable damage to the equipment and possible injury. One of the most essential tools for doing so is a Cub Cadet XT1 deck belt diagram.

As you disassemble it, be sure to keep careful track of each bolt, pin, clip and other small parts to make reassembly easier.

Always take proper safety precautions, including wearing work gloves and other gear, emptying the fuel tank and disconnecting the spark plug. Next, remove the deck from the mower. Locate a small bolt on the right side of the frame, remove it and remove the three cotter pins (one at the front and on each side).


You'll need to remove an additional cotter pin that holds the cable in place, remove the cable, the spring off the deck bracket and the bolts and pins that hold the bracket on. Then, remove the front and rear bracket. While you don't need to remove the arms, some people find that it makes the repair easier.

The next part is most important: removing the existing, damaged deck belt from the mower. If you compare it to the new one you've purchased, you'll see that it looks markedly different from the wear and tear of everyday use. You'll need to pull out the deck to access the clip that holds it in place.


At this point, you can slide the deck out to make it easier to work. This is recommended since the proper placement of the belt is so critical. Typically, the deck belt connects to the spindles and the idler pulley. Refer to a Cub Cadet XT1 LT42 drive belt diagram to make sure everything is connected correctly.


Reassemble the Mower Deck

Now that you've replaced the belt, it's time to put your mower back together. Essentially, you'll follow the instructions above in reverse. First, tighten the idler pulleys and then put the covers back on. Then replace the deck itself and attach it to the mower. You may need to hold the belt in place during this process, so it helps to have a someone who can provide a second set of hands.


Before securing the last parts, double-check the belt placement, and be prepared to re-do some of these steps if it isn't properly placed. Remember, an improperly installed deck belt can pose a danger to the operator as well as the mower itself. Don't forget to refill the fuel tank and reconnect the spark plug, and reverse any other safety measures you put in place. Cub Cadet also has robust customer service, so feel free to contact the company with any questions along the way.
