TO-35 Hydraulics

I have a 1959 TO-35 SDM Ser#193579. The Hydraulics are lifting VERY slow. It will lift blade, rototiller, or whatever but it takes forever to lift it. The fluid was changed about 3yrs ago. Boots and seals are good. Kept out of rain and weather. Is there a screen or filter that might be clogged ? I could rebuild the pump but I would like to try the cheap stuff first. Any help would be great !! Thanks, Andy
 
I don't think the pump had a filter originally in 1959 but someone may have replaced it with a newer pump that does have the filter. Take off the left hand cover with the PTO shift lever and check if you have the filter. If it is clogged up the lift will be extremely slow. In the picture, the filter is the round canister at the left rear of the pump with the tie wire going to it.

Thanks Dan. Does the filter just unscrew after you cut the safety wire? Is it a replacement type filter or just something you clean out and put back in? Do you have to drain all of the fluid out or can you drain a little and maybe tilt the tractor to get to it? tks, Andy
 
Once the wire is cut it just unscrews. There is a separate bottom and top piece to the canister with a metal mesh filter in between. You should be able to just clean it up and reinstall. You can do it without draining the oil. If your hydraulic oil is at the correct level you may get a little draining out the bottom bolt hole in the side cover. I just stick a bolt back in the hole to stop the oil from trickling out until I'm done.

If you don't find you have a filter you can take a look inside while you have the side cover off anyway and check for leaks.

Dan, I opened up the ferg tonight and wow !! That filter screen was really clogged up. Got it all clean and will refill with new fluid tomorrow. Will let you know how it works. Andy
 
Dan, I cleaned it all up and put in 10w30 and it works great !! Thanks again for the picture and help. Andy
