I've replaced both drive belts and the mower moves slow. I have to pull the pedal back to get it to go faster. It's a 2005 or 07 model. Need some advice on how to check rear end or if it is bad.

Post model & serial numbers from tractor data plate or sticker. Scotch front wheels, jack up rear of tractor & give it a go, SAFETY FIRST- MAKE SURE NO PEOPLE OR PETS ARE AROUND. Let us know how it goes, thanks.

Hi and welcome to the forum, Keith! :smile:

I am moving your thread to the MTD section for further discussion. Hopefully someone over there can help you figure out what is going on with that mower.

Almost sounds like the belts you bought are too long. Are you sure you replaced the old belts with the exact same size new ones??

Did you install mtd brand belts, put everything back together properly, and re adjust the speed control linkage?

No I did not readjust it i will try and do that to day? Thanks

Model# 13AM761F065 Do i need to adjust the linkage?

Dang, The best part about mtd was always their excellent owner's manuals, but when I looked up your manual I see it says some boloney about taking it to an authorized service tech instead of telling you how to replace and adjust the drive belts. No wounder all the guys with newer tractors keep complaining about belt issues on all the forums. Probably saves them thousands on ink and paper...
Anyway I found this manual on their site, page 49.

The only time I have ever had to adjust the linkages is when somebody messed with them after they installed generic belts.

As the belts wear you can tighten it up and keep going for a long time before they need replaced. It was considered routine maintenance a couple decades ago...

http://www.mtdproducts.com/equipmen...Code=62&modelNumber=13am761f065&serialNumber= manual & parts list, see pages 20 & 21 in parts manual, you will also need to check idler pulley item 28 for replacement also along with belts items 36 & 37, bearings do wear out in idlers. Let us know how it goes, thanks.

Usually requiring tension rearward on the clutch pedal means the replacement belt(s) are a different angle or different width if the length is proper. Another couple of things are the variable speed pulley has slight wear and that will require an adjustment to the clutch rod and or a higher tension clutch rod return spring.

Good luck.

It is a big file but the Must have manuals are worth downloading.
A little old but they have done the job for me every time so far.

The vari-speed drives had a problem with the two roller bearings in the stack pulley seizing, try putting the mower in park and turn pulley backward and see if it binds.
