[AT] McCormick plow

[Len Rugen]

Odd, our WD-45 would lift the front wheels running over a cow pie while 
plowing.  I think the lift on the arms from the "traction boost" just 
aggravated things, when you hit a tough spot, it pulled harder AND 
lifted the arms, taking weight off the front.

However, a well tuned plow wouldn't cause much side draft on the 
straight and level.  You had to get it level, get the first bottom 
cutting the same as the other 2 both depth and width and get the rear 
landslide so it took the side draft.  I built up the TB linkage with 
welds, got it all tight, adjusted things and it would plow most places 
in 3rd gear.  We just tried to turn too much while plowing, we had few 
square fields, with the trike front, if you dropped the front wheel in 
to the furrow, the only choice was smoking breaks.  I later got a wide 
front WD-45 and that made a huge difference.
