Mtd 38" riding mower. Blades are engaged even when PTO handle is not. Just changed deck belt, blades, and PTO cable and now as soon as I start the mower blades are spinning. When I engage PTO handle the spin faster. Does the belt just need time to streach or is something amiss?

I have 1/2 " x 76" that a repair shop gave me. However factory belt was 1/2 x 77. Will the one inch solve the issue of I charge belts?

That difference can make a big difference. What makes a bigger difference is the use of not OEM or OEM style belts because they have a special cut angle, and actual length this not reflected in the cross over tables. Meaning just because the book says it is a 1/2 x 77 doesn't mean the OEM belt is that exact length and width. MTD and JD use special width and cut angle belts that don't match standard off the shelf belts.

Thanks for the info. I ordered a replacement V belt from MTD and hope that will solve the problem. Will update here once it arrives and is installed.
