Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.
First, check to make sure your belt is not slipping.
Due to your belt being frayed, this can cause it to slip on your pulleys. One way to check it, is by grabbing it, to make sure it is tight enough.
Did our problem occur suddenly?
Your hydraulic system uses oil. Can you get the model numbers from under your mower seat for me?
Thanks! Can you give me a moment to pull up a diagram of your mower?
Thank you for waiting. You have transaxles in your mower. I would like to make a suggestion to you.
Sorry for the delay. I am having site related issues. I had to reboot my computer. I suggest that you replace your transaxle drive belt first.
Have you noticed any oil leaks on your transaxles, or anywhere in your hydraulic system?
Your transaxles require a good quality 20W50 motor oil. I will check for the location of your bypass levers.
Your bypass rod will be at the rear of your mower, on each side.
Take a look at #21 in the image link above. Try the new belt, and make sure your bypass rods are pushed in, before adding any oil to your transaxles.
If you add oil, you will need to purge your transaxles.
Your are very welcome! Let's hope so. If not, we can continue working together. There are no additional charges for follow questions relating to this problem.
