OUT WITH THE L4330, IN WITH THE L5030

Muleskinner · Jul 21, 2005

Don't let my lack of power concern with the L4330 discourage you from purchasing one. It is a fine well made top quality tractor, just not for my type of use.

Now if my L4330 had GST instead of HST I don't think we would be having this conversation. /forums/images/graemlins/confused.gif

I've learned a valuble lesson. I'm very lucky to have a dealer like I have. I could have lost my shirt on this deal real easy. /forums/images/graemlins/blush.gif

( I could have lost my shirt on this deal real easy. )

Good for you! What a relationship. Let us know how that machine works out for you.

Maybe, but from the shuttles I also drive (NH 2120 and Kubota L4850), you might be suprised. I really don't find my smaller and less HP Kubota L3830 HST (same engine as the L39) to have issues pulling what amounts to the same box scraper as you. I am only at 800 foot elevation though and that may make some difference. I think the L39 should be a very good fit. You will learn the GST quickly.

Now a new problem has popped up. Kubota supplies the spool valve, mounting bracket and hoses, but not the cylinders for the top and tilt. So my dealer called Gearmore and was told, "Oh yes we have it, it's the same kit as the one that fits the L35."

The dealer gets the kit from Gearmore and the hose connections won't hook up to the back hoe quick disconnect lines.

Then the mechanic discovers the two hydraulic switching levers on the back of the tractor go one way for the hoe and the other way for the three point hitch. He also finds that when the levers are positioned for the three point hitch, the hydraulic flow is cut off for the hoe fittings.

So, it looks like the L39 may not be set up from the factory to accomodate a top and tilt along with the box blade. (Unless the mechanic is all wet)

The dealer is going to call Gearmore Monday and attempt a resolution. If one can not be found, then I will have them look for a L5030 with GST. This has not been a good day! /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

Does anyone on this forum have an L39 with a rear box blade set up with top and tilt that can help?

Something doesn't sound right here. The Kubota TNT kit for the L35/48 (and I assume the L39 too) requires the 3-spool Kubota remote hydraulic valve. This valve should be plumbed so that it is available when the 3pt is activated. 3 spools gives one for the top link, one for the tilt link and one extra for your hydraulic rippers on the box blade.

I don't think the valve is plumbed into the backhoe outlets which I assume are disabled when the 3pt is activated via the levers. Sounds like your dealer's mechanic might need a lesson in how to plumb one of these things up. Maybe someone with an L35/39/48 can verify this.

I asked the mechanic about that. He said he has installed a top and tilt on an L48, but the hydraulics were different than the L39. /forums/images/graemlins/confused.gif

The dealer should have a hydraulic schematic to consult when in doubt for the mechanic. This should not be this difficult.

Call my dealer, he knows everything about the hydraulics on these Kubotas. They install very nice setups many of which are quite custom. I have no doubts that it can be done the way you need it and quite easily. I went with the Kubota TnT on my L48 and not with the L3830. I like my custom one on my L3830 better then what Kubota had.

Who is your dealer? I'm sure my dealer will balk at that but I need the machine done right, yesterday!!

You should try a rubber track skid steer, You talk about power I watched one the other day (Bobcat T-250) clearing right of way and it was awesome to say the least. It will work circles around anything I have ever seen.
