Ive had this tractor for about 10 years with little to no issues until recently. The last time I used the tractor I noticed the Power steering seemed as if it was beginning to go out as well as the rear lift. I am no expert, but my assumption is the steering and rear lift are both connected through the hydraulic system and on the same pump? I did notice the hydraulic fluid was a bit low so I topped it off to no avail. Basically the rear box and steering will react, but very slowly and jumps a lot. Does this sound like the pump is on it's way out?
