How do you tighten the tension on a John Deere riding mower?

I have a John Deere 150 riding lawn tractor and I am experiencing issues where it does not go at all or it is very sluggish when you push down the pedal. This does not happen all the time and I am pretty sure it is just a tension issue. Much to my saddness, when I found my manual, it was the one in Spanish. Any pointers would be appreciated.

Thanks in advance

LA150, LT150, or?...

It sounds like you may just need a new belt if it isn't tight enough. Most mowers don't have a way to adjust the belt.

It is a LA 150. The guy from the John Deere shop said there was a spring that could be used to adjust it but was of little more help than that

There is a spring that keeps tension on it, but not to adjust it... to my knowledge. I'm not looking at a diagram at the moment, but I don't believe there is an actual adjustment for the belt. I think your belt has worn and glazed and needs replacing.

Just guessing here, but look for a pulley that seized up due to lack of lubrication, then was chewed up by the belt passing over the seized up pulley.

I don't think it's supposed to go if you push the pedal..... Is the pedal the clutch??? If so it may be issues with the belt as I think the unit should NOT move if you have the pedal down,,,This is also the brake...Correct???? Roger

Hi Hoppy,
MTD also has a line of mowers with an "automatic" drive. It is actually just a variable speed pulley arrangement but it also uses a foot pedal to engage the belt, not dis engage.

FYI

BFH..
The ones I'm thinking of (& working on) have the 2 belts with the ""Varispeed"" pulley in between the 2 belts.. They drive with your foot off the pedal & stop when you press the pedal.... Maybe I'm thinking of something else,, but I can drive the units without pushing any pedals & push a pedal to stop,, Lock the Park Brake & get off to pick up the ""Land Mine"" the Dog left for unsuspecting people in the yard!!! Roger
