Was out blowing snow with the GT5000 and the 42" Agri-Fab snowblower when its working its a good unit but I'm getting very disgusted with it, after blowing great for a half hour the belt started slipping (I have tighten per the manual) then pop the belt broke this is what gets me its the 4 th or 5th belt I've replaced over the past 7-8 yrs generally they break at about 10 to 13 hrs I've tried different brands and even went to one 1" longer last year and it broke today 9.6 hrs. I'm beginning to think its the 25 hp Kohler that's the problem, this blower was originally on my Husqvarna for years and never broke a belt Husky has a 15 HP Kawi.; I bought the GT5000 a few years after the Husky so I fouund a 40" Agri-fab blower and installed it on the Husky and the 42" on the GT5000, the Husky is still going with the belt I installed back then and the GT 5000 as I posted has gone thur 4 or 5 belt with many less hrs, The Husky has an "A" belt (1/2") and the GT5000 has a "B" belt (5/8") I have a new Kevlar "A" spare and Monday I'm going to install it as I need the blower yet this winter. I made the mistake of not getting the Case snowcaster out and installed and now I can't get at it DARN I've only lived in Minn 70+ years you'd think I's know better

I would say your over powering your belt. When I went from 12hp to 20hp on my blower I had to go to 2 belts. I'm betting your pullies are under 6 inches in diameter which really cuts down the HP rating of a belt.
 
Could be to much power. Can you change the gearing Gary so it’s easier to run the blower with that engine. Slow auger and impeller down a bit. Then engine may not be at full throttle. Every thing just on cruise, so to speak, then if load increases, the engine will open the throttle more to keep up. Just a thought.

Thanks guys good ideas worth looking into, while changing pulley could be done it wouldn't be easy I think your on to something Chris with over powering the belts and yes for the most part the pulleys are 6" or less with the exception of the blower auger pulley, I could try running the engine at 3/4 throttle vs full that would be the same as changing pulleys slowing things down. I'm going to look into a notched belt I know they run cooler that and less R's. I like the tractor and blower when its working you can really move snow, my other thought was to next year put the blower on my other Husky and go that way.
Thanks guys
 
With all the HP available anymore on GTs why can't someone build one with a hydraulic driven snow blower. I'm sure the HP is there to do it. Eliminate all this belt problem and in cold weather I'm sure oil cooling wouldn't be a problem. I'm sure it would drive up the price but it would be worth it over the long run.

Pretty sure the Kubota 1100 utv thing my wifes grandparents have is hydraulic snow blower. It doesn't have a belt pto


I know the plow they have for it is hydraulic lift and angle.

Heat. Even in the winter heat is a hydraulics enemy. A friend converted his New Holland tractor's blower to a hydraulic front mount. I asked what he used for an oil cooler and he said he wouldn't need one because he would only be using it in the winter. I mentioned the heat and might want to rethink that. After using it he did decide to go with the cooler.
Another thing is most buyers are looking for the most for the least expenditure. Hydraulics are complicated, require more parts and expense to produce. Think of it this way, having the choice would you buy a lawn tractor with a hydraulic 36" blower or a less expensive mechanical 48" blower. I know which way I would go. And for the most part the mechanical blower will work fine.
 
It’s surprising what a 1/2 belt will run. I’ve often wondered how my Ford LGT 165 thrower works, just using one 1/2 belt. Lot of resistance on the thrower when in 2’ of snow, and the 16hp engine at full throttle driving the belt.
The John Deere 140H3 uses a 5/8 belt. And the auger chain is number 60, where is the Ford auger chain is number 40. But both heave the snow good.

My brother has a hydraulic driven blower he uses with his skid loader, he first tried converting a PTO blower to hydraulic after a couple of hyd motors much tinkering he traded it for a factory unit and it works good he's been using it this winter, As Chris post for the average lawn / garden tractor hydraulic is to expensive Ingersol (Case) had a hydraulic snowblower for a while but went back to belt
 
FMC Bolens have had shaft driven blowers, mowers and tillers for many, many years. Most are still going today. Shaft may be belt driven but it is a straight line belt and lot of time 2 belts. Use Kevlar belts and not those F&H or parts store FHP belts.
 
Well I searched & searched could not find a cog belt the length I needed so I called the Vbeltguys in SF, SD got a nice helpful gal on the phone explained the problem I was having and she recommended a cog belt and found the numbers / size that should work so I ordered belts will see when they get here. I have bought belts from the Vbeltguys many time always good service good belt reasonable shipping
