[AT] Farmall 350/300 More Questions

[Tim Nobles]

That's a real good start Mike.  Thanks.   So sounds like it did similar to
an automatic transmission in a car or truck.  Sort of a down shift without
having to use the clutch.

> The TA is a planetary gear arrangement that, when engaged, reduces the
speed of the output shaft by about 1/3 and increases the torque by about the
same amount. It can be engaged or disengaged without using the main clutch,
so if you are baling, for instance, and suddenly need to slow your ground
speed and increase the power, you don't have to stop and shift down to a
lower gear. You just pull back on the TA lever and run that way until the
problem clears, then push it forward to go back where you were. The hardware
involved is somewhat complex and requires splitting the tractor to service
it, so the cost of repair tends to be high.

> Early TA's had sprag clutches that resulted in freewheeling when the
tractor coasted or went down hill. If you had the TA engaged and started
down a steep hill with a wagon in back, the whole mess could start to gather
speed; then if you tried to disengage the TA at that point, you stook a good
chance of destroying the TA. :-(
