I have replaced the mower belt on my husqvarna lawn tractor but the belt is too tight and the blades are engaged all the time. I cannot find a tension adjustor, is there some way of adjusting as I suspect the old belt had stretched and the deck has been adjusted during services to take up slack. Now I have put on a new belt as per manufacturers recommendations it is too tight . Any ideas pls?

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK

Sounds like you need a new PTO switch.

The manual shows how the belts are put on, if you do not have one they may be purchased through dealers or small engine repair shops or online. On mine there is also a little diagram on the top of the mower deck. Another way to check is find an identical one that is functional and look at its belt. There are only so many ways it could fit and these are all made by just one or two manufacturers so there is not much variance.
