I know you've been having problems with one of your fast hitches not lifting the disk. Right away that tells me something, if one tractor lifts the disk and the other wont, there must be something wrong with 2nd tractor. Having said that, I know the chances of one person owning two tractors that lift exactly alike is quite remote. I only ever had identical models of one machine, that being two Case 1737 skidsteer loaders. One of them always had the edge on the other, and it was always the same one having the edge.

Right now I have Super A, 130 and 140 all with fast hitches. The 140 has the edge lifting with hitch, Super A comes 2nd. However one must remember my 130 probably has 10 times the hours of the other two. None of my 3 hydraulic system have ever been apart, other than to take hydraulic lines off to split the tractors for clutch replacement. I might add that edge is very slight.

Where does this lead me, and what does it lead me to believe about tractor hydraulic systems. The offset Farmalls have a very small resevoir, thus leaks must be attended to quickly. Touch control fluid levels must be monitored closely. Far too many folks have thought,"Oh I'm not using the hydraulics, I don't need to check hydraulic oil." The result, many of these tractors have been run low in hydraulic oil, and the resulting heat has damaged the system. Two distinct factors why some touch control systems work well after 50 years with no repairs are adequate fluid and clean fluid. My contention is, if there is great difference in lifting ability of one of your hitches, the lesser one has been damaged by heat or dirt in it's lifetime.

Is your disk an IH factory disk? If so, which model of disk? I picked up a manual this summer for the IH model 120 disk, a quite heavy disk I might add, yet a factory 1 point fast hitch disk for 100, 130 and 140. In that manual it shows an option that gives 1 point fast hitch a mechanical advantage for lifting that disk. A very simple device, a flat piece of steel probably 1/2"x 2" x 6" with three holes. Have you seen one of those your dad may have hung on a spike on the shed wall. It bolts to rear rockshaft arm, making it longer, where pull bar from front rockshaft hooks. This will reduce the lift range, but will increase the lift ability significantly. Maybe your good lifting tractor already has this. Are you sure mechanical linkage is set exactly same on both tractors.

I know this is long but we've been hearing this same basic story from you over a year now and it never gets corrected. I think it's time you looked hard at the two tractors for different setting on hitches. If there is truly a great hydraulic function difference between the two, then will you kindly spend the dollars to rebuild the poor one and quit asking the same question over and over and over, phrased a wee bit different.
