Question about our 5030 HST (hydraulics and 3 pt)

James74 · Nov 8, 2005

We just received our 5030 HST with FEL on September 30th and have about 40 hours on the tractor. My wife and I love the tractor (although she loves her RTV900 more). I do have a couple of questions though. The hydraulics seem weak on the FEL. They go into bypass rather quickly and I am wondering if this is normal. We (actually my Dad), got the tractor stuck in the mud and tried to use the FEL to help crawl out of the mud. The hydraulics could not budge the tractor. The JD my Dad uses for the township can do this with no problem. The hydraulics have a hard time pulling the tractor forward with the FEL even on level ground and not stuck. Am I expecting too much?? Are they adjustable? My wife asked the dealer about the issue and he broke into a long one-sided discussion on the bypass mechanism but never answered the question on whether they can tweaked to give us a little more power.

The other question I have is about the CAT II hitch. My came with 3 bushings to reduce to a CAT I hitch, but the top pin for the top does not fit the bushing. It is almost like the top pin is a CAT I pin while the bottom two needs the bushing to be a CAT I. Is this normal, or did something get switched during prep?

Any comments would be greatly appreciated.

James - I think your dealer needs to buy a vowel. I am pretty darn sure that you can get more power out of your loader. I experienced the same exact thing with my 853, and just talked about it when I posted some pics of my 5030 which is set up for tree work. I believe the max psi is 2,560, and mine was set at the factory to more like 2,300. It is a very simple matter to have a (genuine Kubota) shim or two added in the relief valve to increase the setting (my tractor guy did it for me in about 15 minutes), and the added psi seemed to make more of a difference than the raw numbers would seem to indicate. As I said in one of my other posts, it went from "hmm, this loader doesn't seem to have enough ooomph" to "ok, that's more like it".

In fact, unless my calculations are off, and I don't think they are, I am now able to lift over 3,200 lbs, including my 800 lb. grapple. The stated lift capacity for the 853 is 1,874 lbs. at bucket center, so maybe Kubota is just trying to make sure that their tractors don't get worked too hard. I have other plans. /forums/images/graemlins/smile.gif I figure if the loader can lift it at the max pressure, the tractor should be able to take it. I just make sure I grease the h*** out of the front axle, and take it easy when I have a LOT of weight on the front end, especially when in 4WD. With loads like that, she sometimes makes little groaning sounds that remind me of a draught horse complaining about her burden, but nothing serious. The work has to get done after all.

About your cat 1/2 question, I just read the answer to it in another post, but am ashamed to say that I can't remember it. It was your same exact question though, and if you poke around I'll bet you can find it. John
