B7100 or B6100, What's the difference?

[ccdavis]

My B7100 engine trouble was worse then I thought. I put the project aside until I found a suitable parts tractor that had a good engine.

I just found a guy in my area that is selling a B6100 HST. The pics look like my B7100. The guy is going to provide the engine model number tonight. My model numbers are listed below.

Tractor: B7100 HST D
Engine: D750 AH

What is the difference between a B7100 and B6100?
Will a B6100 engine fit a B7100 tractor?

A B6100 has a D650 motor. It's a bit smaller and only 14HP compared to your 16HP.
