rear hydraulics leaking down

[chip6700]

i just purchased a new b2320 and if i turn off the tractor with the blade on the back all the way up, within 2 hours it will be on the ground. it also leaks down a little while the tractor is running.
the dealer had it for 2 weeks and replaced the "valve" (they said that's all there is to the rear hydraulics) and it didn't fix it. originally they though it was a spring that kept pressure on the control that raises and lowers the hydraulics. then they said it was probably an o-ring. my question is, have many people or really anyone experienced this problem on a new tractor.

This happens to everybody except Eric McCarthy, he can keep his up all day

It's a very common thing that you just get used to. While the tractor is running and if you're not using the 3ph then periodically pull the lever and give it a bump up. You may be able to crank in the knob to slow it's down rate. But, you will get used to it.

One more thing. I know you were probably just checking but it's a very dangerous safety practice to leave the 3ph raised and the tractor off. If you have any pets walking around the tractor that 3ph can be like a guillotine.

thanks for the reply scott. and you're right in that i was just leaving it up as a test because i agree it's too dangerous to just leave up and walk away. i just didn't think the hydraulics on a 2 month old tractor should leak down. how can you use a blade effectively if it won't stay in the position you put it for as long as you need.

You are right in thinking hydraulics shouldn't leak down after 2 months and that is exactly what I was thinking 5 years ago when I bought my tractor. I wouldn't worry about it too much, don't let it get to you.

Even under the best of circumstances working a blade to smooth an area would be very difficult. Every time the front wheels go up or down the blade will go the opposite way.

When you are actually using the blade you will be making quick periodic adjustments anyway so you will not even notice bleed down of the 3ph.

I'm with Scott on this one. The 3ph you'll constantly adjust and fool around with to work the grade and move material. And why is it everybody hate's me because my stuff stay's up? I cant help it I can keep it up all day long!

Aint hatred - it's jealousy

Kubota seems to be less and less concerned about there hydraulic leak down specifications. They have a 2 page form to fill out with pressures and specs to determine whether or not it is considered a "leak". The easiest way to figure out what is causing this is to close the down speed knob that is located under the seat. I think that is what they tell you to do when you park it. That at least narrows down the possible causes. There is mostlikely a cylinder overload or safety valve, the control valve, and it could possibly leak down in the cylinder itself. I actually heard a kubota rep say the following to address this situation- "Look at all the tractors on your lot, find one that the arms arent down, and switch the hitch cover and valve with that one."

There is a special place in the after life for people like that
