RE: (ET) Towing Capacity (tow weight vs. draw-bar force)

[Larry Elie <lelie ford com>]

I have never tried to measure the draw bar force from my single-belt E12.  
However, I have 
skidded 14" x15' logs, and, on one occasion, moved my father's 14,000 lb. 
(empty) combine 
on a flat concrete floor.  I only had to move it 6', and the belt did not 
squeal in LL.  My guess 
is the draw-bar force was less that a ton, but was well beyond what the 3 
of us guys present 
could move.  I have also lifted the front end (without the mower attached) 
on a log.  Remember, 
the old steam locomotives moved hundreds of tons of mass on flat, hard 
rails sometimes with 
only tens of HP.
