Q:

How do I stop the V belt from coming off on my riding tractor?

A:

I apologize for the trouble you have had with the tractor drive belt coming off.

If the tractor is used correctly, the clutch will only be pushed in for starting. After the engine is running you do not need to use the brake to stop. The motion control lever will apply the brake when you move it to neutral. When you move the motion control lever to forward or reverse the tractor will respond without using the brake or clutch.

If you are using the clutch and brake to stop and start the tractor, it will cause the drive belt to come off.

If the belt guides are in place and properly adjusted, the motion drive belt should not come off in use. I am sending you a diagram for the position of the belt guides. Be sure all the belt guides are in place. Adjust the belt guides so they are 1/4 inch from the back of the belt when the belt is tight.

To determine if the loss of power is in the belt or the transaxle, pull the clutch pedal up with your foot while climbing the slope. If this causes the tractor to climb ok, the problem is in the belt. If this doesn't affect the loss of power, check the fluid in the transaxle.

To check the fluid in the transaxle remove the pipe plug on the left side of the transaxle case. The fluid level should be level with the bottom of the hole the plug came from. There is a pipe plug on the top of the transaxle case to add the oil through.

The transaxle on your tractor uses 10W40 motor oil.

My belt falls off on a 917.270622 when I fully depress the brake, not while riding. However, while riding around bushes and trees I may have to hit the brake, and when I do....off comes the belt.

I finally figured out how to keep my V belt from falling off and in place. As I was driving I saw a tractor like mine. It was a 1998 21HP 50�. I noticed that this mower had a belt keeper above the transaxle pulley. I found that the belt keeper part numbers was156109 or 164173 with the hex lock nut no. 7390050. One of the mower model numbers I researched was 917273320 and the belt keeper part number was 123405X but has been updated to 164173. I am disappointed that the manufacturer and all the technicians I had try to fix and talk to could not figure it out. Their answers mostly were that I needed a new belt or the guides needed to be adjusted. I have spent a lot of money on new belts and replaced belts that have come off and shredded. It is apparent to me that the manufacturer saw the need to add this belt keeper and did not bother to pass along the remedy for the belt falling off. Is there a way to update the manual to add the belt keeper part? Is there a way to let others like me who contact Sears know of the remedy also. I want to change my transaxle fluid and am unsure where the lower pipe plug is to check the level. Could you supply me with the key number and part number to help me find it? My understanding is the upper pipe plug to add oil is part number 142914 (key #95), correct? How many ounces of motor oil will it take to fill? Thanks in advance for your help.

Thank you for your question.

I know how frustrating it is when a belt will not stay on. If you have checked the belt and it is routed correctly, I recommend adjusting the belt guides and keepers. Each pulley should have a piece of metal that is right next to it. This part is to keep the belt on the pulley when the clutch loosens the belt. I like to remove the mowing deck to adjust the belt keepers. When the deck is off you can easily access all of the pulleys. If you are not sure how to remove the deck, please see the instructions I have provided below out of the manual. Once you are ready, park the tractor on a level surface and set the parking brake. Then look under the tractor at the keepers. The keeper should be no more than a 1/4 inch from the pulley. If it is, just bend it closer to the pulley. Once you have adjusted the keepers, test the operation. After you are satisfied the belt will not come off, you can reinstall the mower deck.

I hope this information is helpful.

Please let me know if you run into problems.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website: Sears Home Services .

Thank you for using Manage my life.
