JD2555 and a few Allis Chalmers and now one Kubota
I know your going to think I am crazy, but can you get a 75?
When you put 56 horsepower into motion, and then hit something solid, it pays for it to be a little over-built!

My opinion is to big or go home. The gearbox needs to be bigger than the HP of your current or possibly future machine for sure. Spending a few extra bucks for a beefier part is good insurance in my book.
If you are putting more HP into a gearbox than it's rated for that's just asking for it to blow up on you. Warranty's won't cover abuse outside of operating specs.
