[AT] Now: PTO to Trailer

[charlie hill]

Most of the old tractors I have run start to get loaded up going up a slight 
grade in their own road gear.  Add the weight of a wagon and the load of the 
pto/truck axle drive train and I don't believe the tractor engines had 
enough power to push the rig much over 15 mph or so.  Just a guess.
