Need input from Front End Loader owners

[Anonymous Poster]

My JD4300, Hydro 4WD, with 430 loader has dump creep. The bucket won't stay in a fixed position. Slowly creeps in dump direction.
My question is what's the correction-FIX?

Dave, it sounds like you're going to have to determine whether the seals in the bucket cylinders are leaking, or whether the control valve is leaking and letting the hydraulic fluid seep back. When I had the B7100 I had the same problem, in addition to the whole loader gradually sinking. The factory service rep thought it would be the control valve, but after the dealer checked the valve and found it was OK, they tried putting new seals in the cylinders and when that didn't correct it, they just replaced all four cylinders with new ones, and finally fixed it.

What are the differences between the Kubota LA450S and the LB400A? The Specifications are 99.9% identical. Both loaders are now approved for usage on the L2500, L2600 and L3000 tractors. However, the LB400 is listed as light duty. I have emailed Kubota but they have not responded.

Gary -

According to the owner's manual the 2 loaders are nearly identical. Near as I can tell, the 450 is simply built a little heavier.

Specifically, the 450 loader itself is 105 pounds heavier than the 400, and the 450 bucket is 31 pounds heavier.

Presumably, this makes the 450 a little more rugged than the 400, but doesn't it also mean that the 450 has 136 pounds less lift capacity?

I have the LB400 on my L2500, and although I've only put 20 hours on it so far, I feel I've tested its ruggedness. While digging my culvert ditches I was lifting the tractor on the cutting edge of the bucket and then pushing it hard through my rock-laden soil. Numerous times I ran into to boulders which jarred the tractor to a halt, and the only signs of wear afterwards was on the paint.

From what I've read on this board, I could improve my digging capability by adding bucket teeth, but all in all I would say this "light duty" loader is more than up to any challenges that I am likely to throw at it.

You heard it from a newbie. /w3tcompact/icons/smile.gif

I hope this correction-FIX isn't taken in the wrong context..........trade for a Kubota?

Harv,

Thanks for the information.
Our local dealer did not have either of the loaders in stock so I did not know what they looked like. I was going to order the LA450 until I saw the picture of your tractor. I have seen the LA480 loader and was definetly impressed with this loader. I especially like the routing and size of the hydraulics. Other loaders I looked at used 1/4 inch flex lines routed through the frame. The Kubota used 3/8 inch flex lines connected to neatly routed metal lines for the long sections. I would expect this configuration to last longer and be more trouble free. Kubota finally did respond to my request for information on the two loaders. In a nut shell they said that the 450 was built slightly heavier....and that the 400 would be satisfactory for all but very heavy duty applications.
