Without the model number, I couldn't tell you what belt goes on the ground drive. That 174883 is a 5/8 x 97" and is your deck drive belt. Your ground drive belt may just need replacing. They will wear thin and loosen up between the pulleys and cause the problems you're having. The old belt may still have the numbers on it.

Belt diagram for deck belt craftsman 1000

From the pulley under the engine, take both sides an go straight back, between the two pulleys in the forward inside position, go past them and then out to the blade pulleys around the front of the pulleys and to the outside and then the back and then across the back. If you are looking down from above from the seat, "looking through the mower" you would see an inverted T shape.

I hope this helps get you going.

I need to tighten belt for the mower deck, how is that done? it is a 2004 craftsman 17.5HP 42 " deck. Can you help me

Each of the pulleys on top of the deck should have tensioners. These tensioners are usually the type which have a bolt for you to tighten while attached to the pulley. While you tighten the bolt, the pulley puts tension on the belt.

Craftsman 42 inch cutting deck riding lawn mower. I can not get the mower to to ingage. The belt appears to be tight and has not follen off the pulley.

Some of the 42 inch Craftsman mowers Have a cable that goes from the blade leaver to the deck some have a linkage if it has the cable check it to see if it has broken. Find where it connects to the deck pully and pull on the cable wire not the cable cover and see if if comes out also make sure it is connected to the top of the idler pully. If it has a linkage there is a clip that holdes that linkage to the deck it most likely came off.

Craftsman model 917.271814 will not go forward or reverse. Heard a "click" and mower stopped moving; engine and blade still running.

Check the drive belt that runs back to the transaxle,it sounds like it broke.If the belt is in the pulley check to see if the transaxle pulley is turning when the clutch is out.Also make sure both wheel axle keys are in the rear wheels.If all this checks out the transaxle may have broke,look underneath to see if it is broken there.

I need a diagram for installing a deck belt on a 42' Craftsman Mod.#917259330

You can download the User Manual here from ManageMyHome,

(Just copy, and paste the above into your address bar, then press the Enter key)
On this page where it has Go in the blue square, go below that, and click on -> View Manual.
This is a PDF file download. Took me about 12 seconds to see the first page, (I have Medium speed DSL )

Page 22, (Service and Adjustments), starts showing the routing of the belts.
The deck belt makes a T shape. It goes around the two mower blade pulleys, (Mandrel Pulley), and then around the engine shaft pulley. There is a tension pulley is on the left side, it's on the outside of the belt, and pushes IN on the belt. There is a tension pulley on the right side. It's on the outside of the belt, and pushes IN. (Pushes in. Pushes towards the center of the mower)

The Motion Drive belt goes around the rear end pulley, (Transaxle Pulley),
goes up the left side of the mower, to a pulley that is mounted solid to the deck, (Stationary Pulley), comes to the inside of that pulley, then goes to the outside of the Clutching Pulley, up around the engine shaft pulley.
From there, it comes back along the right side, to all the way to the Transaxle Pulley.

Should you wish to save a copy of the above manual, it's easy. In the header bar at the top of the PDF file is a Floppy Disk icon. It's the second icon from the left. Hovering your mouse cursor on it, will briefly reveal,
"Click to save this file to your computer or another location"

You will then see a ->Save a copy:, small window come up.
At the bottom of this window is the Filename:, box.
Put your mouse cursor in the box right after the -> f, in .pdf
Left-click Twice. Make 1 space with your spacebar. Now type ->
Craftsman 42 inch Mower Manual. Then go to the bottom right of the window, and click on -> Save.

If you do not have your downloads set to download to your My Documents folder, this will go to your desktop screen. In any event, just double-click on it to open it. You can also burn a copy off to a CD.
(If you do not type Craftsman 42 inch Mower Manual, or something you will recognize later, you will be going around looking for ->L0901538.pdf)
