Water in tire (Part 2)

[SC2555HST]

If I have the rear end jacked up (weight off wheels), the valve in the upper most position, and remove the valve and water comes out, does that mean the tire has water filled at least to the valve or higher or would the air pressure in the tire be forcing the water out?

The reason I ask is, I feel like my rear end has gotten lighter since day one. The dealer filled the rear tires when purchased, approximately 6-7 months ago. Last week I was scooping dirt with the stock 72" bucket and a full load made me feel unstable and brought up the rear end a few times. I figured I lost some water over the past few months, so I went and bought a $9.00 tractor tire water filler device. I attempted to use it, but water was flying out when valve removed, so I figured it was full and discontinued the attempt.

I can't remember what the bucket use to lift as I have been using my 72" EA dual opening grapple exclusively for several months now.

Thanks in advance for any words of wisdom.

This would indicate that your rear tires are overfilled. Your operators manual should indicate that rear tires not be filled beyond, around, 75%. It should be this way so that the air in the tire can compress when encountering a bump, rock, etc. A tire filled 100% with water will not compress the water when contacting a bump, rock, etc. I would surmise that its better for the tire to deflect when encountering something as opposed to no "give" at all.

With the correct amount of fluid in the rear tires you WILL loose some weight as ballast. This can be overcome by adding ballast to the 3-point system - I.E. some form of implement or ballast box.

You NEED weight behind the rear tires for scooping dirt or heavy loads on the FEL. Without the weight on 3ph, you are putting extra stress on the front axle. I would say 700# at the minimum. :2cents:

Do you have a mower or box blade to hang off the back of 3ph?

Also, yes, you have too much water in the tires...

As teg has indicated. When you use the FEL/grapple to scoop/move material - there should always be something on the 3-point. Having the rear tires "lift off" is not a good situation and can lead to an accident. I have the rear blade - 566# - on my 3-point at all times. If I'm going to do some heavy FEL or grapple lifting I'll change over to the roll over box blade @ 720# plus a cast concrete square @ 480# for a total of 1300#. You DO want to keep the rear tires on the ground at all times.

Thanks guys. I usually do keep the box blade on, but I was at a different location where it wasn't at. This should fix my problem. Thnx. I shall also bleed off some water just in case.
