I have an early Super A that I just bought a front blade for. After hooking everything up I was excited to push something, but the lift doesn"t have enough power to get it off the ground unless I helped it with a six foot rock bar. It seems to have plenty of down pressure. I have a 3-point finish mower that I used last year and if I remember right, it had problems lifting it also, but had enough power to bend the rod that connects the 3-point to the lift. I have never done anything to the tractor except oil change, grease, and some electrical. Where do you start looking? The manual lists the oil in the Touch Control system to be SAE10W. What modern fluid is recommended to replace it with. I have only had the tractor for a two years and I don"t know what fluid is in there now and I don"t want to mix types.
 
Are you using the Touch Control arms, or how are you trying to lift it? Is this blade made on purpose to lift the way you are trying or adapted from another application? If you have plenty of down pressure, it would seem there is no problem with the pressure the pump is capable of producing.
 
I am using the Touch Control arms. The gentleman that I bought it from showed me how to install it and I have looked at pictures on the web. When I had the mower hooked up it would slowly lift it as I drove. I believe it is an A60 factory blade. I have not found an id plate yet, but it looks like what I've seen on the web.

Thanks,

Rob
 
spring assist for Lifting might be needed. 20 wt oil will not hurt anything, Hytran is recommended today, but it is also thin. Jim
 
Mite need to clean the screen. Another question do you need to add fluid often and the seal in the pump could be bad and leaking the fluid into the crancase when under pressure.
 
Could be the screen, and it won't hurt to remove and clean it. It's under a cover that's held to the hydraulic block by 4 bolts.

Changing the fluid won't help. Regardless of how dirty it is, it's still incompressible fluid, and if the pump was capable of putting out adequate pressure, the hydraulics would work.

My money is on the pump being shot.
