I recently replaced the deck belt on my 85 John Deere 111 because it snapped. I used a 1/2" V-Belt 66" long. (hopefully its right). Well I noticed that when I am mowing I can have the mower in second gear and it will loose momentum on the slightest incline. and there is alot of play in the drive belt. I want to go ahead and replace all the belts. Does anyone know the right size of the belts on my mower? Does anyone have a owners manual online for this? maybe a pdf? I am also curious if I used the right size belt on the deck. Please let me know. Thanks in advance.
