I have a B1750HST BI-Speed with a RC60-B mid mount. After 10 yrs of ownership, I've grown tired of the annual spring and fall changeover from the mower to the dozer blade. I love the mower deck, as it mows great and blows the leaves in the woods in the fall, but I'd like to convert it to a rear mount. I'm not worried about making the 3 pt attachment work, but the problem is the mower gearbox. The mid PTO is at 2455 RPM and the rear is a 2 speed - 540 & 858. So I need to increase the spindle speed to come close to what the mid PTO drives it at. I have thought of going to a machine shop to make me a new set of gears, but I'd bet it would be pricy. Any ideas?
