Go to and download the owners manual.
After that I would go to and look at the pictures of your mower deck (again you need the model #). Once you figure out what you  need then all you have to do is order then from sears.
Good luck!

How to change pto belt on club cadet 1046

To replace a transmission drive belt on a Cub Cadet LT1046 you need to remove the deck, preferably put the front wheels up on blocks or stands, unplug the PTO power (directly under the engine, which can be a pain ) You need a 5/8" socket to get the bolt out of the PTO pulley assy.(electric clutch). If you don't have an impact wrench take a spark plug out and push rope into the hole. This will bind the cylinder and keep the drive shaft from turning. Remove rope and replace plug when finished. Battery and/or spark plug wires should be removed for this process for safety.
The PTO may be stuck on there so you may want to tap it with a hammer and a block of wood carefully to release it. Loosen old belt from tensioner pulley. Lower engine pully on drive shaft, below pully "keys". It may be difficult to remove. Spray with "PB Blaster" or similar bolt loosener spray. Remove old belt from engine pulley first, transmission pulley last. Remember how belt goes around pulleys before doing so, make a diagram to help.

You'll need to put the belt on the transmission pulley first then thread the belt up to the engine pulley. Thread your belt back through the pulleys and tensioner (make sure your spring is strong enough to tension the belt or buy a new one).

The PTO pulley is "keyed" on the shaft. Replace bolt and washer. Torque bolt to 38-50 ft. lbs. using the rope meathod as described before. Put your deck back on and you're ready to mow again

When pto engages top belt comes off

Make sure that the belt guide is in place near pulley. You can also check to make sure that the tensioning spring for the pulley is in place, not missing, or not over stretched causing the belt to jump of the pulley.

I have a Cub cadet my 1018 with a 42 inch deck my iderlerspringcameoffneedtoknowbothbothplaceoneachendtoreconnect

Go to your local cub dealer with the modle number of the deck. They have diagrams that will show how to connect the spring correctly. If the spring came off it may have lost tension or part of the hooks on the end of the spring broke off. I would get a new spring. I have also seen the the idler pully get sloppy and not keep the idler pully properly lined up with the other pulleys.The belt will then ride up off the pulley and the spring will come off.

My John Deere L130 PTO will not disengage, it starts with the blades running. Everything else is working okay. Fuse has been replaced. Could it be the switch or what?

You may have grass stuck under the pully that is supposed to glide as you engage the PTO. Now, the grass is preventing the pulley from springing back to the position so the belt does not have tension and, therefore, does not spin the blades.

Why will blades will not disengage?

check your return spring on the deck. it goes from hole in bracket welded to deck to hole in moving lever that one of the deck pulleys is attached to. if spring is missing or broke, it will not dissengage or may dissengage slowly. If spring is there, the moving lever may have debris under it or may be bent. If spring is there, remove deck and try pushing the pully with the spring to see if it breaks free.

Mower blade will not disengage, and the cable is intact. What else should I check?

missing return spring (on mine, its on top of the deck forward) or sticking mechanism. With mower off, you should be able to push back on the idler pully and the deck belt should loosen up. If its sticking, pull the deck off and see whats causing it (may be stick or dried grass). If its missing spring, dont try any old spring from hardware store (hmmm could this be from experience???), but order one from ebay or amazon or whoever has it cheapest.
