Hi guys, I have an old 1835B that I lent to a friend to do some yard work. The steel line going from the back of the loader to the tilt cylinders cracked and developed a leak. I had a replacement made and installed it. Some hydraulic oil had leaked and the guy put about a gallon of ISO32/SAE10 hydraulic oil into the reservoir. After installing the line, he "drove it for 5 minutes and everything worked fine." Later today, his son "took it across the yard and it wouldn't go any further. He said there is a leak of some fluid back in the engine compartment." It has run for less than 10 minutes with the gallon of different oil in it (I doubt this is a problem, but it's the only other thing that's changed except the line). He tells me it, "moves a little, enough to load it on the trailer." Any ideas what I'm up against here? I need to use this thing tomorrow to unload my pickup and I'm hoping you guys have some ideas what might be wrong here. What could be leaking in the back near the engine that would cause it not to move? The drive pumps and motors are all up under the seat, aren't they? I'm encouraged it's a leak, as that likely means there is nothing wrong with the pumps, motors, etc. Thoughts? Thanks in advance! Jim
