Safety and Preparation Serious injury can occur if the engine or mower blades accidentally start while you are working with lawn tractors. To prevent this, drive the Murray lawn tractor onto a flat work surface and disengage the mowing deck cutting blades. Engage the parking brake to keep the mower from moving; chock the wheels with a wooden block or brick. Adjust the mowing deck to the lowest position. Turn off the engine and remove the key from the ignition. While not necessary, you may even wish to disconnect the spark plug wire from the spark plug. Mowing Deck Removal You must remove the mowing deck on a Murray lawn tractor to gain access to the belts. Remove the adjustment rod hairpins, followed by the adjustment rod pins from the front left and right sides of the mowing deck. At the rear on the left and right sides, pull out the retaining hairpins and slide the mowing deck suspension links from the adjuster plates to separate the rear mowing deck from the frame. Remove the blade control rod stud, including the hairpin and washer, from the top of the blade control lever shift linkage at the left rear of the deck. Remove the front hanger rod, including the hairpin and flat washer that hold the rod in place. Loosen the belt guide retaining bolts with a socket wrench and remove the engine stack pulley belt so you can slide the mower deck out from under the tractor Transmission Drive Belt Installation Slide the new transmission drive belt between the engine stack pulley belt guides, over the belt guide plate and under the engine stack pulley. Fit the transmission drive belt around the top engine stack pulley. Push the free end of the transmission drive belt up through the transmission shifter hole in the lawn tractor floorboard. Slip the transmission drive belt loop over the transmission shifter. Pull the transmission drive belt down through the transmission shifter hole. Fit the transmission drive belt around the transmission drive pulley and tighten the transmission drive pulley belt guide retaining bolts to hold it in place. Fit the transmission drive belt flat side around the idler pulley. Slide the idler pulley onto the idler pulley stud while holding the belt in place. Tighten the transmission idler pulley retaining nut with a socket wrench to secure the idler pulley to the idler pulley stud. Mowing Deck Drive Belt Installation Pull back on the right side mowing deck mandrel pulley spring-tensioned belt retainer. Guide the new mowing deck drive belt around the right side mandrel pulley and release the belt retainer. Pull the drive belt spring-tensioned retainer away from the mowing deck idler pulley, guiding the deck drive belt around the idler pulley. Fit the mowing deck drive belt around the left side mandrel pulley and under the rear mowing deck cross link rod between the right and left side mandrel pulley. Slide the mowing deck under the right side lawn tractor frame, reconnecting the deck to the frame in reverse order of removal. Engage and disengage the mower deck while driving the mower to test the belt for proper operation.

Hope this helps. Serpentine Blade Drive Belt
1 Lower the mower deck to its lowest position.
2 Route the serpentine blade drive belt (part number 6109) onto the V-pulleys located on the mower deck. One double pulley is located at the front of the deck near the center. The other two pulleys are located near each side of the deck. Route the belt around the outside -- the side toward the outer edge of the mower deck -- of each pulley. For the double pulley near the front of the deck, route the belt around the lower pulley (part number 6058) only. If pulleys are fitted with belt guards, work the belt in between the pulley and shield.
3 Push the idler pulley toward the center of the deck with your hand. The idler pulley (part number 6059) is the fourth pulley on the deck and is located near the rear of the deck. It is the only movable pulley on the deck. Wrap the belt around the side of the pulley nearest the edge of the deck. Release the idler pulley to place tension on the belt. No adjustment is necessary because the serpentine idler spring (part number 6065), located on the idler pulley, adjusts the belt to the correct tension.

yes, you most likely have a bad seat switch (operator presence switch) check this first.

You don't need a diagram to install your deck belt. V part of belt goes to V pulleys and flat part of belt to idler and other pulleys.

These are a pain. You can go online with model number & get the diagram. Its the same as a John Deere. You will have to loosen the steering arm 7 rasie the steering wheel just enough to pass the belt thru. Make sure you mark its position for reailigning before disconnecting. Diagram should also be in your owners manual. Goo dluck with this one

This is for a Scotts 1642. Picture yourself sitting on the mower looking down at the deck. Starting at the tractor pulley, the belt runs from the right side of this pulley to the left side of the tension arm pulley, around this pulley to the left side of the right hand side mower blade pulley, around this pulley, across the deck to the smaller left hand side idler pulley, then up to the left hand side mower blade pulley, around this pulley to the second (larger) idler pulley, around this pulley and back to the left side of the tractor pulley. If you make a small sketch of the deck pulley arrangement it will be easier. Keep in mind some of the pulleys are for the "V" side of the belt and some (The tension arm pulley & larger idler pulley) are for the flat side of the belt. Be sure the belt is not twisted and lays in a continuous circle with the "V" side of the belt on the inside before you start.

I don't have a deck diagram but you should be able to figure it out it you put the back part of the belt (flat) up against the pulleys that are wide and the narrow part (v) into the smaller pulleys. It might take a couple of times but it is not that hard to figure out. Also put the (flat) side of the belt on any tension idlers. Hope this works.

The belt travels from eng. pulley directly to the transaxel pulley riding on the inside/center of the tractor side of the idler pulley. make sure the belt retainer is on the idler pulley.

I have to replace the belt part number m124895 on a Scotts riding mower.I need the belt configuration,since i bought it used.
Please help
