[Farmall] how to check a ta on a Farmall 400

[Mike Sloane]

The only way I know is to operate it. While the tractor is moving, 
simply pull back on the lever all the way, not touching the clutch 
pedal. The tractor's ground speed should immediately drop almost in half 
with no sounds or vibrations coming from anywhere. Releasing the lever 
forward should immediately and smoothly increase the ground speed to 
where it was. The TA works the same regardless of the transmission, but 
the difference in speed is most noticeable at the higher speeds, so try 
it in 2nd or 3rd. Generally speaking (from experience) the TA either 
works or it doesn't - nothing in between. If the seller suggests that 
"it just needs adjustment", I would be concerned, as all the adjustments 
do is determine the position of the lever when the TA engages.
