Mower "jumps and bucks" when I push levers forward. What needs to be adjusted?

When was the last time the drive belts were changed? This is the first thing I would be checking. While checking the belts on a 13 year old unit, I would also be looking at all pulleys, drive and idler, to make they sure they are not worn and bearings are in good condition.

Changed the belt and one idler pulley about a month ago.

 

[Rivets]

Are the idler arms providing the proper tension on the belt? Did the problem start after you serviced the drive system? Did you use an OEM belt or a aftermarket one that says it fits your unit?

Have you changes the oil for the HYDRO's? Check for low oil or air in the lines.

A neighbor has told me there is too much slack in the control arms. That is the next thing I plan to work on, because it definitely needs attention. Another person has suggested checking/changing the hydraulic oil.

Thanks for the response. I hope to get a chance to work on it later this week.
