2000 JD 4300 Leaking, and spraying hydralic fluid on left front tire

[Gary546]

I was pulling my driveway, the other day, when I noticed Hydralic fluid spraying on the left front tire. I don't knoww if it's coming from a fitting or a pump.Has this happened to anyone else? searching for answers.

I don't know about how common this is, but you should be aware that hydraulic fluid spray is VERY DANGEROUS.

A high pressure spray of hydraulic fluid will penetrate your skin and can flay the flesh from your bones in less than a second. I have seen horrifying pictures of the results.

If you do not know exactly what you are doing, take this to a dealer or skilled mechanic, no matter what it costs.

Sounds like you have a bad hydraulic fitting or hose and needs to be corrected immediately.

It sounds like you have the infamous battery acid corroding the oil cooler problem. I had that happen on my 4200 shortly after I bought it, and fortunately it was corrected under warranty.

Carefully check for the leak using cardboard, I use drywall shims for that purpose if it's not blatantly obvious as to where the leak is coming from. If you have the old fashioned battery with caps for adding water, then get a new sealed maintenance free battery. You're still stuck going to Deere for a battery as they used an odd size that isn't readily available in the 4200 - 4400 series, or fabricate new battery mounts for a more common battery group size.

Check for acid corrosion on the cables and elsewhere if that is the cause of the leak.
