[AT] How can they farm like that

[charlie hill]

I remember reading one Progressive Farmer article about tire slippage where 
it explained
that a tire could not roll without slipping (I guess unless it had an 
infinitely small contact patch).
It continued to discuss the optimum % of slippage for applying HP to the 
ground.  If I remember
right it was between 12 and 15%.  It occurs to me that that percentage range 
turns up a lot in
agriculture and construction.  Everything from wheel slippage to moisture 
content in grain
and also in the wood in a building.

We only had one jack and inadequate cribbing on the farm, so we never 
bothered making sure the treads headed the right direction.  Besides, the 
rear tires had closed ends on the rubber cleats and we were never able to 
detect any difference in traction regardless of the direction of rotation. 
I used to read the tire ads in Successful Farming and wish WE had those 
new-style treads that cleared themselves of mud, etc.
