[Farmall] Odd 340U lift problem (long)

[Larry L Hardesty]

Yes, there is a pin that goes near the bottom of the cylinder.  It is not 
as straightforward (obvious) as the pin for the Super C or Farmall 400 
that results in power down, but one can have power down with the 340 
fasthitch.

One thought I will add on the down pressure question, I believe the bottom 

of the cylinder is attached to a part that can pivot.  There should be a 
pin 
intsalled to keep that part from pivoting.  If the pin is out, there will 
be 
no down pressure.
