I have a new to me Grasshopper 930D with 72 inch deck. Only 275 hours. I mow fescue. It ran fine until the end of last season when I tried to grind up some already bush hogged tall grass. I burnt the PTO belts in the back when I got into some heavy stuff. Fortunately it was the end of the season.
In the off-season I had the dealer replace the belts (a fairly complex affair, unfortunately), and he said he changed the bearings also. I used it this April and promptly burnt the belts again. I was mowing what seemed like reasonable-height grass (?7 inches) to 3.5 inches. The dealer replaced the belts for free, but felt "I must have gotten into something thick, or hit something." I know the area well and doubt I hit anything.
I mowed a few more times early this month and it worked fine, but every once in a while I thought I might have heard a squeak from back by the belts. I always mow at 5.5 inches except the one time at the beginning of this season. The belts were warm, but not hot, and no belt dust. I have three zones that I mow and I mow a different one every 3 days.
Today I mowed an area that had been last mowed 9-10d ago. Grass height pre-mow was 10 inches, but not thick, just scraggly at top. Sure enough burnt a belt in back and it snapped.
My questions are:
1. Even with quick growing spring grass, is it typical that a zero turn cannot handle every 10d mowing?
2. Might there be some increased tension distal to the PTO clutch that is causing increased resistance?
3. There is a snowblower attachment that goes on the tractor portion of this unit. I am surprised it can throw snow and not mow 10d growth. Perhaps I should not be?
4. I have a tractor and a 6 ft rotary mower, but use it mainly for the fields, and do the work around the house with zero turn because it's so maneuverable. Is there a better option for around the house, gardens, etc? The Kubota F series is pricey but might be the best option. I assume it also has a belt driven PTO?
I'm awfully frustrated that it appears a 30 HP diesel is so limited by a belt.
