Thank you for your question.

I am sorry you are having a problem with the mower. When this happens, it is usually because the pawls in the drive gears are stuck. Taking the drive apart and cleaning the pawls usually cures the problem. To access the pawls you have to remove the rear wheels first. Then remove the c-clip securing the drive gears to the shaft. Once the gear is removed clean, the gear and the pawl with break cleaner and reassemble the mower. Do not use any kind of lube on these parts because it will catch dirt and grass that will cause it to stick again. If you are still having problems, check to make sure the belt is releasing when you let the handle go. If the belt is not loosening, it will cause the same problem. This is not likely.

Please let me know if you need further assistance on this problem.

Thank you for your question. I am sorry you are having a problem with the mower. It sounds like you have pretty much covered everything. I am not sure the belt is going to cure the problem. The reason is you are having the problem when it is turned off and you are pushing it. I recommend checking the wheels and the adjusters. If the teeth inside of the wheel are worn, the wheel can bind and lock up. If the wheels seem to be fine, check the bearing in the adjuster. If the bearing is worn, it will allow the pinion gear to move away from the wheel gear. If this does not help, I think the problem is in the gear case. Somehow, it is engaging when being pushed. You could test the mower with the cable disconnected. If it does the same, it is a defective gear case. Please let me know if you need further assistance.

The belt needed replacing and definitely a tighter fit... all the parts in the gearbox are fine...the handle lever pushes forward and locks into place to engage the self propel function...the wheel gears are good and not a problem nor the adjusters...when i release the kill handle slightly, the lever pops back but the gears don't disengage...I can't even manually disengage it when the motor is off....too much tension. I have to pop the cable off the bracket.

Thank you for the reply. If it will disengage when the cable is removed from the bracket, I recommend checking the cable first. If the cable looks fine, try to adjust it. I have provided you with the instructions for adjusting the cable below. That should cure the problem. If by chance that does not cure the problem, you could try to bend the cable bracket closer to the engagement lever. Only do this as last resort. Please let me know if you need further assistance.

the engage handle is on the left side and a lever that pushes forward...a simple setup and no adjustments possible on the design I have....bending the bracket did not help either...I will clean the pawls but they seemed pretty clear of debris when i was working on other items.

I would like to ask if the front drive wheels on a Craftmans lawn mowers are interchangeable. i.e 193144 & 700783,&407755X427. All the wheels show teeth on the inside circumference.

A:

We normally recommend that you use the replacement part that is listed by the manufacturer for your model. All of the front wheels may not be interchangeable. I looked at the 3 wheels that you listed in your details above. According to the parts images, those wheels appear to be similar. I suspect that they would probably all work as replacement parts for the same mower if they are compatible and fit. There is no way to tell for sure. You would have to order one and try it.

Q:

What is causing the drive wheel gears to wear on my mower?

A:

I pulled a call history at our tech center for you model number, I don't show what would be considered "excessive" calls for that type problem. The manufacturers do pay attention to how many of certain parts are sold/bought to monitor potential problems as well as they are in contact with retailers for feedback on problems as well. I realize that doesn't really give you much of an answer, but the design is effective and does work better than the way they used to be. We have less drive wheel problems now than we had 5-10 years ago.

My older lawnmower Sears model 917.378311, also front wheel drive shows no wear of the internal gear on both left and front wheels. Both left and front wheel internal gears are in excellent condition after 9 years. I have ordered and received new front wheel replacing the damaged right front wheel. I have used the mower with the new right wheel for approx 3 hrs. The internal gears look okay so far but there is some grass cuttings in the gears. Who do I call about the warranty covering my cost of the damaged wheel replacement?

Thank you for your question.

I will be happy to assist you with replacing the rear skirt. I have looked up the model number you have submitted. The skirt should be attached to the mower with two hinge bolts. These bolts have a long shank that protrudes into the skirt. In the image below, I have marked the bolts in red. You might be able to remove one of the bolts and slip the skirt off the other.

Please let me know if you need further assistance.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations: Sears Home Services .
