Disappointed in my Deere for the first time.

[Gary_in_Indiana]

First, let me say that up until now I've been very happy with my tractor. Today I was using my box blade and broke a piece off my rear axle housing to which my lower three point arm attaches. I was shocked beyond words to find that my entire rear axle housing is cast aluminum instead of steel! /forums/images/graemlins/shocked.gif /forums/images/graemlins/mad.gif

To say that I was shocked and disappointed doesn't even begin to describe it. I have come to expect more from Deere than this and, quite frankly, I think I have a right to. All I can think is, to paraphrase a country song lyric, "What were they thinking?" This is a tractor axle housing, not some child's toy or decorative knick-knack.

If it was steel a) it probably wouldn't have broken and b) if it did break I could weld it back on. I called my Deere dealer and found there's no shortcut of which he's aware, though he is checking for me. Further, a new axle housing (still made of pot metal cast aluminum) is $1400 in the box. He guesstimated labor to be two and one half to three days minimum so there's another four figure expenditure because Deere cheaped out instead of using steel. Unbelievable!

You capable of removing it? Cast aluminum can be brazed or welded if appropriate pre-/inprocess-/and post-heating is used. Can't imagine a local welder would charge anywhere near what your'e talking.

Aluminum can be a great material for some things, an engine block for example, but that sure doesn't seem like one of them. What would be the advantage over cast iron? In general, aluminum is more expensive than iron. It would be tough to make a cast aluminum housing that could stand the abuse that a good cast iron alloy will. Could the weight advantage really be that important?

Gary this has been discussed quite a bit in the past. Sunday evening I did much the same thing. I snapped my lower link connection while foolishly trying to move a massive embedded granite rock with my Kubota. I was backed into the rock and in low range. While lifting the 3 pt hitch, pulling in the hydraulic top link the rock lifted and as I was moving backwards, I heard a loud pop. A drooping 1000 lb boxblade the result. I had broken a large piece of the cast iron housing that also is the attachment for the 3pt lower link. A bit mad at myself for doing what I knew I shouldn't, but also relieved that the part is a separate chunk of cast iron that is pretty easy to replace. I emailed TractorSmart, Ronnie the parts manager sent me several pages showing exactly how it's replaced, the part number and the cost. Monday evening I ordered it, Tuesday I got the confirmation it was ordered and today it was here. I paid $8.00 for shipping for a 39lb brake case (right side), sealant and an engine oil filter. The cast piece while a little expensive was not as bad as I had imagined, $215.00. I am incredibly impressed with Tractor Smart, unbelieveably great service. My lower link strut was what caused the attachment to fail (above and beyond my stupidity). As thick and stout as it is, I bent it enough to twist in its socket enough to basically pry the cast attachment point and with the right rear corner of the box blade pushing hard and all the leverage of the lower link and box applied, it fractured. OK, lesson learned. It took an awful lot for it to happen. I hope you can find someone to work with as incredible as TractorSmart, they are truly fantastic.

Here is the reply Ronnie gave me:

Mark,

The part broken is called the brake case RH part number TD050-28620 price 216.65
The liquid gasket sealant is part number 70000-74000 price $8.20 for 3.5 oz tube.

I did not see any seals that would need replacing in performing this operation.

It is going to be some what of a job to replace it.

Insurance? Maybe you have insurance on the tractor. If you financed it with Kubota you probably for sure have insurance.
Unless you are equipped with jack stands and a hoist just removing the rear wheel can be a pretty heavy job as they may be filled with fluid and would be very heavy.
Just wanted to mention the insurance from the stand point of you may get a dealer to do all the work and your deductible may not be any more than the part.

I'm confused - doesn't Gary have a JD?

 

[slowrev]

Yeah, I thought it was a JD as well.

 

[Dave4410]

I would have sworn he has a JD.

"I hope you can find someone to work with as incredible as TractorSmart, they are truly fantastic. "

I know there was a lot of verbage in there. I wanted to relate that I had the same experience and hoped he could find someone as good as I thought TractorSmart is. Thats pretty much it, plain and simple. Two guys, different tractors that did much the same thing, /forums/images/graemlins/crazy.gif

Utmost, I found your post very informative. While the differences between iron and aluminum are pretty drastic, I think you proved that both materials can fail.

Iron is a brittle metal but handles stress but often not shock; aluminum has a higher strength to weight ratio, but can be brittle as well, and handles stress differently and can fatigue under some circumstances.

Thanks Bob, you understood it in the spirit with which I intended. You are right about the metals.
