OK ..... I have a 72" Land Pride grooming mower that I pull on my Kubota tractor to mow the 3 acre field in from of my house. Last week when I mowed the field it wasn't mowing very well and the belt (I thought) was slipping so I stopped the mower and tightened the spring pulley that adjusts the tension. After mowing for 5 minutes the mower stopped and the belt had come off. I put the belt back on and reduced the tension. 5 minutes later the belt came back off so I just parked it and finished the field with my zero turn yard mower (pain to mow that much with it).
So this morning I go out and take off the covers thinking that one of the pulleys or spindles may be loose and wobbling from a bad bearing causing the belt to come off. Nope all sturdy and working fine. I put the belt back on and put quite a bit of tension in it and start mowing without the covers so I can see how the pulleys are turning. After 5 minutes and I turn my head away from the mower the belt comes off ..... this time shredding it.
Would the belt more likely to come off due to too much or too little tension. Belts are too expensive to put one back on and shred it again without knowing the problem. Any ideas or common problems that cause belts to come off? I can usually fix something I can see, but I don't see anything wrong.

Pulley misalignment and excessive heat from failing bearings have been the cause of most of my belt troubles.
It doesn't address your problem John, and I don't know the ins-and-outs of matching pumps and motors, but I think I could go for all-hydraulic drive ... i.e. get rid of as many belts, chains, sprockets, gearboxes as possible.

Thanks Frank ...... didn't notice excessive heat, but I did think about bearings. I have replaced at least one pulley bearing on this uniy and although none are wobbly, that doesn't mean they are not about to go.
