Hi Jdemaris. I have a 19543 Ford NAA which is basically the same tractor as a 4 spd 641. 1st gear at 1750 rpm is 3.31 mph, at 2000rpm (wide open) 3.58. I will agree with the others, either the tractor is not a 641 or it doesnt have LPTO. Live pto via 2 stage clutch was available with the 5 speed trans and selectospeed trans only, not the 4 speed. 5 speeds were known as "pump shifters" as neutral was up and down and gear selection was moving the shifter forward or back, where the 4 speed was a conventional shift pattern. That is a fair price for what you describe if everything is in good shape.Do you have a rotary snowplow that you pull , or a blower that you back up with? Rv speed on the 4 speed at1750 rpm is 3.45, 2000 rpm is 3.96. Too fast to do much snowblower work in reverse. An overrunning clutch is a good idea with the 4 speed tractor(I use one on my NAA and do quite a bit of brush hogging with it) . The 5 speed may or may not be LPTO, the LPTO tractors have an overrunning cluch built in.Hope this helps.

When dealing with thinner metals like sheet tin, a long bolt and
