[AT] How can they farm like that

[charlie hill]

Wow, my memory is pretty good.  I think I read that article in the 70's.
I said 12 to 15 but we farmed sandy loam so that is about right for our
conditions.

Here is an article and a graph that shows slippage vs  HP applied to the 
surface based on surface
material.

Certainly an interesting subject Dean.
I'm sure the pullers study it long and hard.

Charlie,

It wasn't too long ago that I read an article about the required optimum
slippage to get the most HP
to the ground. That was really interesting as that was something that was
not discussed on the farm
that I recall.  I suspect pullers use that to the maximum.

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.
