Will a cub transaxle handle 100 hp? What mods will need to be done? Looking to put a kz1000 in front of it, was wondering if it will handle the hp and the rpm. The rpm will be between 8-10 grand. Thanks

No, and doubtful anything can be modded to make it handle that kind of power.

It might be able to handle the power but you'll have to upgrade all of the internal parts. I've been told that some of the alcohol burning pullers are making 60-80 hp.

I'm guessing that tractors running that kind of power would use something other than the original rear end. I would check with other people running that kind of power to see what they are using.

You will need to up grade shafts and bearings but it will easily handle 120 HP! That's what the alcohol v twin Kohler's are making and they are putting it down through cub rears toughened up.

Copar Panzers could probably handle it because they had narrowed Mopar rear ends in them. They still probably would have to have been well maintained.

 

No, and doubtful anything can be modded to make it handle that kind of power.

I think im right around 40hp with the diesel without any big amount of mods done. Theres a guy that pulls at my girlfriends club and I think he has an 1100cc motor and is using a cub rear but you better have some good parts in it. I would get a dart rear and go from there. A good set of gears and a over driver as well. heavy duty shifter forks along with a 4 speed unless you want reverse.

Even with the Panzer's real axle you would still need a drive train small enough and strong enough to handle that many horses.

Panzer axle will break. The way panzer built them they just butt welded them together.

That would be very helpful, I don't know anything about a cub rear end. I have heard about the dart carrier, but the rest is Greek to me. If it makes a difference, I will be pulling on dirt. I plan on using a kz1000 engine and running a straight shaft to the cub rear end. Right or wrong??? Any ideas
