484 Hydaulic Leak

[Jay in AL]

Good evening!

This afternoon I was out on the tractor disc-ing up some new pasture to spread some seed. I was not really using the bucket much for anything other than moving it here and there so that I could see properly ahead of me.

Anyway, at one point, I went to raise or lower the bucket and noticed that it wouldn't move. Then I noticed that it would move up, but not down, and it would not tilt either. By the controls I noticed some hydraulic fluid beneath the joysticks and dripping on to my right foot. After playing with it a bit, I decided there wasn't much I could do at the moment, so I continued to disc and then about 10-15 minutes later, one of my hoses down by the bucket sprang a leak and started spraying fluid all over the tractor and me.

I got it back up to the house, and now I'm trying to figure out where to start troubleshooting this.

Here is a link to some pictures:

Any thoughts out there?

Hi Jay, looking at your pictures of the hydraulic control valves, is the leak coming from the pressure relief valve (the tubular cylinder with the nut that screws onto the body of the control valve)? If it is you can try tightening the nut some. Be careful if you try to remove this relief valve as it is under spring tension. It is common for hydraulic hoses to spring a leak after years of use and damage to the outside by rubbing on metal parts. Split an old heater hose to put over hydraulic hose anywhere there is abrasion.

Hopefully there is not a piece of hydraulic hose floating around in your hydraulic system. My brother had a strip of rubber about an inch long in his loader hydraulics once.

Good Luck
