    Right, that makes sense. Hydraulic oil cooler is oil to air exchanger, correct?

    JD 4440 water in hydraulic fluid

    Tractor is used for field work, but since the last hydraulic oil change it has really only been used on the disc bine. When running the disc bine tractor always runs cool. Needle on temp gauge barely makes it to the green mark. Maybe it isn't getting hot enough to burn off the condensation? Or...

    JD 4440 water in hydraulic fluid

    My main concern was that somehow coolant was entering the hydraulic system, but it sounds like that's not possible. I know the tractor hasn't been out in the rain so it can't be coming in that way. I was getting a transmission light before the last time I changed the oil. Since then it has...

When I cycled the cylinders I contaminated the tractor hydraulic fluid with water. I initially drained the fluid and refilled with new fluid. I drove the tractor for...

    Mixing Radial and Bias Back Tires JD 4440

    Our John Deere 4440 needs one new back tire. It currently has a nearly new rear radial on one side, but needs a new tire on the other. After calling around for prices; a new bias tire costs about $900, while a new radial is close to $2000. I'd obviously prefer the radial but that is a...

    7410 Completely Dead No Electrical

    I was using our 1996 7410 and the alternator light started flashing on the dash. Shut it down and completely lost all electrical when I went to restart it. Came back a couple hours later, all power came back and started right up. Just yesterday went to use it and the electrical not...
