[AT] Now: PTO to Trailer

    You all need to do some refiguring on the speeds this tractor would 
travel. PTO speed is only 550 rpm and with a direct drive to the rear axle 
on the trailer would be the same. A 50's Chevy six cylinder would turn about 
2800 rpm to go 50 mph with a 4.33 ratio, so, 550 devided by 2800 gives 
approximately 20 percent of the speed of the truck or about 10 mph. Bigger 
tires or a higher ratio may bring it to 15 mph. Not an unreasonable speed, 
even way back when.
    Course, maybe he had another transmission mounted backward for 
overdrive, then all bets are off.

                            Gene
