I posted a few months ago with a concern over my hydraulics on 5000 hour 4440 Quad Range I recently bought, they are "buzzing" and 3 pt was raising real quick, although I have decided the 3 point maybe normal and just much quicker than other brands. What I have found after using it is that the first remote gets much hotter than the others, not too hot to touch but much warmer than the 2nd and 3rd. When I raise the 3 pt. this "buzz" stops as the arms lift then returns. It seems to buzz from the remote 1 area. I disked stalks and at first I was using remote 1, unaware of the heat difference. It worked well at first and was fully extending and retracting automatically pretty well, although not perfectly crisp. After an hour it stopped raising without considerable effort/messing around with the lever. Number 2 works perfect. Number 3 works great but is very hard to get the line plugged in, requiring tapping the end with a small hammer. I have a theory knowing the previous owner/history that remote 3 has never been used since new, and 1 has probably been used 99% of the time. Since I got it back home I have been using it to move implements around the farm. Remote 1 works sometimes and others it takes considerable effort to get it to raise, I adjusted the linkage after discovering that it would raise better but only when adjusted much farther, to the point it almost is right at the next detent position to get it to lift. I serviced the tractor and there was a very small amount of what I thought could be real fine metal particles out of the last of the filter, I tried picking them up with a magnet and they seemed to cling, although it was hard to tell exactly given their size and them being in oil. A family friend who has run 30/40 series since they were new thinks maybe it is just somewhat normal Hi/Lo Clutch? liner wear. He didn't see the particles but is going off my detailed description. It is possible they were the "greyish" he describes, I just can't tell for certain. Everything runs and shifts great, except for the remote 1 issue/buzz. If this is a high pressure remote 1 leak then how serious is the issue? I can use the other remotes and never need all 3. I could take it to John Deere this Winter if an internal leak is going to cause more damage, but with 45 bu. corn this year and no crop ins. I'm not exactly looking to spend anymore this Winter than I have to. This is my new workhorse tractor and I'm part-time, will be putting about 100 hours on it next year, no other option. Any opinions are greatly appreciated.

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.
