If the cylinder is mounted upside down, lifting of
the hitch happens as the piston rod retracts. The
displacement of the rod must be subtracted from the
displacement of the cylinder. That means less force
in a shorter time. I am not going to bother doing
the math but the push of a cylinder is ALWAYS
greater than the pull. You can take that one to the
bank.
My point being that the cylinder is always between the same two mount points. He is not fabricating mount points for it. On all the 3 point units I have seen, expansion = raise.
And I have done that calculation more times than most. Far more times. :roll:
If it has the mounts for two cylinders I prefer to split the volume into two 3" small rather than one 4". It eases the role of the rock shaft.
