Heavy Duty Gear Reduction Box

Anyone have any leads on where I can get a gear reduction box that is rated a little higher than 31 HP?

Ive seen General Pumps and a few others, but they max out at 31 HP.

I can tell you this much, there are no geardrive boxes with big enough input gear larger than for 1-1/8in shaft. Not enough to broach either.

31hp rated box is about as big as you’ll find for a small engine. Belts are your friend.
