B3030 wear and tear

[eyedoc]

I was doing some dirt work in my back yard a few weeks ago and loaded the pickup bed with some clay that I wanted to get rid of to make room for some good top soil. The truck was load (over loaded actually) and I still had about a 1/2 scoop of soil left. Since I didn't want to make to trips (lazy), I drove the tractor back to my office about 1.5 miles away with the bucket half full. That is where I store the tractor and where I was going to unload the dirt.

So anyway, I drove 1.5 miles on smooth city streets with the 1/2 full bucket, dumped the bucket and proceeded to put the tractor in the garage. That is when I noticed that the loader was acting funny. It would elevate at normal speed but would only go down at about 1/4 the normal speed, maybe even slower than that. All other hydraulic functions were fine. It just lowered in slow motion. I started to call the dealership, but on a hunch, I restarted the tractor, and miraculously it worked fine, and has ever since. I called the dealer and the service manager had never seen this happen before.

Do you think that carrying the 1/2 bucket of dirt for several minutes could have jammed the hydraulics? This is my first tractor so I have no idea if I should have avoided carrying that load so far. It seems to me it should be OK, since I could easily be faced with tasks like that on my farm.

Any Ideas?

The dealer just picked it up yeaterday for the 50 hour service and will check it over since I am about to reach the end of the warranty.

The joy stick loader control simply had a lot of back pressure on it due to the loaded bucket.

The poppet valves and springs in the four way valve were slow to release because of the nature of the valve design and any air in the hydraulic circuit, its no problem;

No charge for diagnosis, send cookies-the baked type only.


Please remember me if you want to sell it to a poor wanna be hobby farmer :^)

Thanks!

I thought it might be something simple like that. Maybe you should be the service manager at my Kubota dealer. That guy had no clue. Oh well, they are going to look it over anyway since it is still under warranty.
