Plid,that is far too slow and not normal, I am not really familiar with a 424, I have a B250 which is in that series I believe. My guess is that there is a restriction some where, I would start with a fliud check and a check of the filter, a screen that is in line on many of those era tractors.( I just checked my IT manual and it lists B275,B414, 424, 2424 and 3414 as similair) The followimg trouble shoot is given as you described. System lifts slowly:1. System overloaded. 2. faulty hydraulic pump. 3. suction filter plugged . 4. speed control piston stuck in the slow position. 5. faulty relief valve. 6. low oil in reservoir.....now since you have strong lift you can rule out some. I have valves on the B250 to turn to set front loader or rear 3 point. If they are not fully opened I get slow motion..does the 424 have this feature? The manual suggests 3 gallons of hy-tran for a tractor of that size, with the filler plug open run your pumps to purge air out of the system. I don't know where the filters are on a 424 but on the B250 there is an in line screen on the right of the trans housing beside the drivers right leg. This is where there is a coupling that comes apart to drain the hydraulic fluid to change it..inside that coupling is a screen which could be clogged..don't know if I helped or just made things worse but I am suspicious that there is a clog somewhere and its either the filter or the in line screen..good luck from Mike in Exeter Ontario
