The 1955 is a 74 model. I know the gearbox has been into twice, And this last time it had to have several new gears, and about all the bearings were replaced. Of course, we have no idea how many hours the old girl has on her. I have often thought about trying to find a 4b for one of the 88's. That would make heck of a machine. Sadly, with no power steering, no 3 pt hitch, & poor hydraulics, the ole 88 wouldn't be worth as much as a 50 or 55 series.
One of the driveability issues we recently beat is the cab noise. My brother is pretty handy when it comes to metalworking/welding. He found a White cab off of a 2-105. Painted that thing up green & white & got it to fit on there. The A/C works better, & the cab is so Much more quiet. It is probably the best tractor we have for driveability. P.
