Sam: There is an interesting side note with all of these touch control units. They always leak if lifting heavy loads as the rockahafts go towards the rear, or cylinders retracting. If you never put that type of load on them, I don't think they would ever leak.
My blade lifts that way, as does the factory blade. When I first had my blade, I had it on the Super A first winter. It caused the hydraulics to leak around the rams. That was 1990 and the Super A torque tube dried off 6 months after I last had the blade on it. Since that time the blade has been on my 130, same thing, all winter the torque tube is wet with oil. By the end of june it's dried up.
I think if folks would refrain from using touch control on retraction lifts, leaks would be less previlant. I would advise anyone looking at using a blade, go to an implement cylinder and remote valve.
You drove my 130, that tractor has been through the mill 10 times over, on is 3rd set of pistons and sleeves, yet hydraulics have never been apart. On that big disk I have using my 3 point hitch kit, the 130 lifts that disk to full height easier than my 140, and I doubt if the 140 has seen 500 hours of work lifetime. But then you get right back to what I said on Greg's thread this morning about tractors parked for long periods. The lubricants drip down from the upper extermities of every component as in engine, hydraulics, transmission and rear end plain any simple, over time oil is replaced by rust, and rust causes far more damage than use. When farming I saw this with big tractors, when hours went on fast and furious the repair cost per hour is far less than the tractor doing couple hundred hours per year.
Of course one of the big live hydraulic problems with IH tractors out of the 40s and 50s, the reservoirs were too small, many of them got low in oil and had more than one hot session. It required close scrutiny of hydraulic oil levels. Then you had the operator that decided since he wasn't using hydraulics, no need to check the oil level. I always tell those folks, that hydraulic pump will last as long without oil as your heart will without blood. Usually jolts them a bit.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
