[AT] Actual tractor question

[Stuart Harner]

It seems really unlikely there is still air in the system after all the 
cycles it has done.

Is it possible to swap the hoses where the two sides are tied together?

My guess is that there is an internal fault in a hose on the left side. 
If there is, swapping the hoses would move the problem to the other 
cylinder.

You could also swap the hoses for the bucket and the lift at the valve 
and see if the problem remains in the lift or if it moves to the bucket. 
That would confirm the valve function.

Both of these should be easier than swapping the cylinders which would 
be a last resort option to prove it is in the cylinder itself.

Just some off the top of my head ideas to isolate the problem.

My tractor blew the main pressure line the other day and pumped the tank 
dry before I knew it. Replaced hose and refilled. Two cycles of each 
cylinder purged all the air and it once again was running smoothly.

Hopefully someone else has some other ideas.
