Question and Answers

Q:

My lawn tractor Model 502.255750 jerks/lurches while in motion. 502255750 Craftsman Sears 11 h.p. lawn tractor

A:

Thank You for choosing Sears PartsDirect.com. I regret to hear that you are having issues with your mower and do understand your frustration. Glad to help out. Im looking at your model number 502.255750 and this could be caused by a belt or pulley failure. It could also be caused by a problem in the transmission.

I recommend that you check the drive belt and pulleys first. Replace the belt if it is worn. Check to make sure that the belt is routed properly and that the pulleys are spinning freely. You could have an issue with an idler pulley.

If the drive belt and pulleys are okay, I recommend that you have a service technician examine the mower. You could have a problem with the transmission that need to be diagnosed and repaired. Get someone to drive the tractor up an incline while you walk behind. Watch the freewheel lever when the tractor starts jerking and see if it is moving out and in. If the freewheel lever is moving the problem is in the transaxle. If this is the case some customers have added a spring such as a clutch return spring to hold the freewheel lever in. This has solved the problem, but we don't know for how long.

I don't think the clutch adjustment would cause this. There might be a pulley slipping on a shaft. You could also have a worn pulley, letting the belt slip. You should be able to see this by the wear on the pulley sheave.  If the transaxle is jerking when you move the shifter, I recommend moving the shifter slowly forward. This should slowly engage the belt. If it still jerks badly, I recommend checking the shift linkage between the shifter and the transaxle. If it is binding, it might be causing the belt to engage too fast. If it seems to be fine, it could be a belt is grabbing. I hope this information helps with your troubleshooting.  If you have further questions please resubmit your question for further information.

Thank you for providing the model number of the engine. Unfortunately, I was not able to find a manual with the engine model number. I will need the complete mode number directly off of the tractor. The model number should be on a sticker on the top of the mower under the seat or on the fender. Respond to this thread with the model number and I will gladly look up the manual. Thank you for using ManageMyLife.com.

Q:

riding lawnmower mows part of the time and not part of the time. replaced drive belt. what should I look at next?

A:

I know how important it is to have a good working mower in your home so that you can keep your grass maintained. While you are waiting for an expert answer, I did manage to find a link from the Manage My Life website that will provide you with some good information about what may be causing your problem. If you do decide to have a technician diagnose and make repairs, an option is to visit Sears Home Services and use the handy scheduler,which I have also added the link below. Hope this helps!

Thank you for your question.

I am sorry you are having a problem with the mower. This mower has two belts. It has a primary belt that comes from the engine to the mower deck. The other belt is the timed secondary belt. That belt is between the two blade mandrels. If the mower stops mowing, all together the problem is with the primary belt or pulley. With the engine turned off and the key removed engage the mower deck lever. Then reach under the mower to see how tight the belt is. If it is loose, you will need to check the idlers first. I recommend spraying the idler pivot with WD-40. Then work the engagement lever to loosen it up. If it seems fine, look on the engagement lever and linkage. There is an adjustment for tightening the belt. I am sorry it has been a few years I do not remember how to make the adjustment.

If one of the blades stops working, from time to time I recommend checking the secondary belt and pulley. The secondary belt is a cogged belt. To check this belt you will need to remove the mower deck from the tractor. Then remove the belt cover. To see if the belt is slipping, hold one blade and try to turn the other. If you can turn one blade independently from the other, the belt or pulleys need to be replaced. The repair parts can be ordered from the link below.
