Mower will not engage - wheels do not move forward
My self propelled mover is a Toy Built 22", 5.50 horsepower, Briggs and Stratton 550 Series, 158 cc, Model Number
12A-264U011, number directly the model number is 303526.
I changed the height of cut today, started the mower, engaged the self propelled arm and processed to cut grass. The mower moved forward and cut about5 feet, then all of a sudden just stopped moving forward. I released the arm and engaged again, the mower moved forward under power, then stopped again.
Can you tell me what to look for? I did note that the line that is attached to the forward motion arm is a bit loose, that is, it has some slack in it.
This has been a great mower. I had it exactly one year and 3 months. I purchased this mower after my husband passed and needed something I could handle at the old age of 70.
Awaiting your response.
First off, thank you for your excellent and well worded question.
More than likely you had a drive belt break or come off the pulley. Remove any grass or debris from the top of the mowing deck and inspect the belt. If it looks loose or worn, replace it.

I hope this helps and please let us know. But if you have more questions about it come back and we will get into more detail.
Yeah, they leave out transmission malfunction in that troubleshooting guide. I just opened mine up and the pin holding the spring in place to engage the gears had snapped in half. The new assembly is somewhere around $70-$100, but if they had a exploded diagram of the parts inside the transmission, I could probably buy said pin for $2. I'm guessing they don't want folks to fix their own equipment. If anyone knows of a place to find individual parts for their transmissions, I'd love to find out about it.
