Took my oliver 1850 about 5 miles mostly in 5th or 6th direcet drive to cut hay. Some time between point A and B it started leaking hyd oil. I got to my field and just as i entered the field I noticed smoke from the hydraulics under the seat. i shut down the tractor and opened all cab doors and windows. got out and found that i had a significant hydraulic leak on the side with the hydraulic levers. it was so hot that when i sprinkled a tad bit of water on it the water imediatly sizzled and boiled off!!! after a few minutes i took of the hydraulic fluid dipstick and it was bone dry! but there was such a mess it was hard to tell where it leak came from i think it was where the remote levers shaft enters the valve. I got some oil and filled it up again. at no point did i use any of my hydraulic remotes or the lift. I was in road gear. by this point it was to dark to inspect further. so here i am. what Happened? any ideas on were to start looking tomorrow????? im totally lost. and is it safe to drive if i keep the hyd fluid full and go slow to get home???? or does it need to be trailered? also where do i find parts for the valves ?? if thats what it is? also it seems that when i try to lower my moco (tried to after refilling hyd fluid )(single acting cyl )the hyd system lifts it back up imediatly after i take my hand off the lever. it was setup for a sing acting cylinder. it seems as if the pump still pressureizing the lines if that makes any senesce ?????????????? please help.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
