I think that I am on the trail of a bad valve... I had an interesting idea, and that would be, that if the arms have trouble going up due to a piston related problem, such as rings, or just a lot of wear, then the arms would come down quickly, because they couldn't hold pressure.
Well, I fired it up, and let it take it's time to get the arms ALL the way up to the top, I am sure of it, couldn't pick them up anymore. Then I shut the machine off, and just sat there and watch to see what would happen. I instantly heard a weird bubble noise, I look in, and below the pto shaft, air is bubbling up through the oil? So I go around and stand on the lift arms. They start to go down, in surges, and for evey surge there is a LOUD bubble in the oil. It went down about 2 inches, and then stopped. From this point, 400lb's couldn't make them budge.
So, if I am correct, that should eliminate any possibility of a piston related failure, right??
If that is the case, then I figure that it must be a valve, or the pump just can't get enough oil, but then how is a person suppose to explain why it does go up very well at first, and then it all falls apart????
Getting close, I can taste it...
However it tastes like 80-90... EEEWWWWWWWWWW!!! :)

Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
