    Default Broken Mount For LA724

    I was using the backhoe and moved the rear of the tractor over to reposition it when I heard a loud snap.I got on the tractor to use the FEL and noticed it was lopsided,looked down and saw the bracket broke clean in two.After going back to the garage I was able to get the loader off.I called the dealer and he said he would come down Saturday to take some pictures and send to kubota. The loader has a 12 month warranty and the tractor is 15 months old so I am thinking Kubota won't do anything about it after reading other posts on here about similar situations.The tractor has 530 hours on it and most of that is FEL work.I do use it but I don't feel I did anything with the loader that I shouldn't have.When I use the backhoe I lay the FEL bucket flat on the ground so that it will slide when I reposition with the hoe.Maybe moving the tractor around with the hoe is not a good thing to be doing but I thought it was common practice when using the backhoe.After looking at the other bracket I noticed that it has a crack in it as well.You can see from the rust that the broken bracket also had a crack for a while before it broke.I will wait to see what Kubota says but I am thinking I will probably end up welding and reinforcing both brackets.I make my living as a welder so I feel confident in doing this if it is necessary.This incident has kind of left me soured on tractors but that will probably pass with time.I guess tractors are not industrial machines like a real backhoe and are only made to do light work.I never really envisioned something like this happening from the work I was doing with the tractor.Curious to see if anybody else has had a similar problem.The tractor is an L3240.

    Just curious - what does your owners manual have to say about performing these type of manuvers ?

    On a heavy-duty industrial backhoe maybe .....

    Correct.

    It's not so much that they are only made to do light work as much as it a case that they are not made to be completely abused ....

    Just like any machine, they have their place, and they have their limits .... exceed the limits and you will likely have a problem at some point.

    Personally, if I were you, I'd consider myself lucky - the loader mounts can probably be repaired fairly easily.

    Imagine if you broken the ___________ (fill in the blank: rear end/differential, transmission, etc. ....)

    I have a full size backhoe. And a 2002 kubota L3710. In 2003 I bought a Woods backhoe. It will move the tractor around easy. I also lay the bucket flat. But I really don't use the Kubota any different than the full size. So I think you have defective loader brackets.

    On any hoe I have ran I always pick up the front bucket to slide it around with the hoe. I can not imagine the leverage you were puting on the loader and i would bet its hard to move with loader on the ground.

    On the flip side it don't look that hard to fix. dont worry your not the only guy that learned some hard way. As I have had most of my lessons that way. Good luck
    If it ain't smokin' it's broken.

    The real question isn't whether the BH will move it around ....... but will the machine stand up to having this done to it ?

    I can move my tractor (B2910) around with my BH4690B 'hoe too ..... but I don't.

    As powerstroke point out: consider the (side) leverage being applied to the loader arms (and thereby the mounts) - ya really think that they were designed to withstand those kinds and types of forces ?

    Or are they designed to be operated in a manner which contemplates mostly up/down and front/rear forces, with very little in the way of lateral/side forces ?

    I assume you didn't lift your front bucket when you tried to move the tractor, if so I wouldn't expect kubota to cover it. I often to what your talking about, plant the front bucket so the backhoe can't pull the tractor backwards but I raise it when I want use the BH to move the tractor. I guess you know the weakest link.

    I would consider myself lucky that's the only damage you did. You easily could have twisted your loader or damaged the backhoe frame.

    By any chance do you have kubota insurance on it? If so I thin it would cover the damage if the warranty doesn't.

    I just wanna say your tractor looks great for having 530 hours on it Very clean looking for that amount of hours. On my old B, the rubber mat on the floor board had a whole worn it at 50 hours. Your mat looks like its never been stepped on.

    I hope you and kubota/dealer can work out something positive.

    Well that sucks. When using a backhoe I usually lift the front bucket before moving the machine with the hoe. Hopefully those brackets don't cost too much.

    Would be interesting to know if the brackets differ between the ones on our 3240's vs the ones set up as backhoes. I think they are called LTB's?

    OUCH.

    I don't have a BH myself, so not knowledgeable about moving the tractor around with it, but your 4th pic, the one showing the crack that hasn't broken yet, makes it look like there's been extreme side forces put on it ... when the bracket's real strength is +90 degrees to that.
