GP Hansen said: (quoted from post at 11:37:15 03/04/13) It"s noticibly twice as slow as the 3 point or tipping the bucket. It would take 10 - 15 seconds to raise it to full height at half throutle empty. It"s been slow since I"ve had it.
The 3 point appears to be an after market one but works fine.
At half throttle and figuring 2.5 to 3 gpm is "prioritized" for the power steering, you really don't have a lot of flow to work with, so it will be slow. As I said, I suspect my 240U was changed to a second crankshaft driven pump when the Char-Lynn PS was added. If I am below about 1/3 throttle, my 3 point does not work at all, and need to get to half throttle for it to work smoothly. Mine has an added priority valve that taps off about the first 3 gpm for the PS. Yours with factory PS no doubt has the priority flow valve built into the stack valve under the dash.
I used a row crop 350D on a ranch in SD in 1964, and it used the internal valves for the loader, but I don't recall it being slow. However, what we used it for was to load hay bales with a Farmhand 8 bale loader... lift and tilt cylinders worked off the tractor loader valves and a 3rd added valve worked the hooks that tilted into the bales. I don't recall how the flow was tapped into for that 3rd valve, or if it had a second pump... don't believe it did. I doubt we ran it at 1/2 throttle though as we had 400 acres of irrigated alfalfa and we kept moving pretty fast. This was also before I worked 38 years for a hydraulics company and wouldn't have known then what I was looking at anyway.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
