It does make you wonder why they can't forsee these kinds of failures on a computer long before the part or entire machine is being made. I know a lot of high end CAD or engineering design software lets you model stresses on parts long before they are even sent to be made. Why the hell they didn't change the same part both sides I will never know. That's ridiculous and has caused undue downtime. It doesn't give you much confidence in a manufacturer who are clearly not looking out for the owners best interests. If that combine had been a car a mass recall may well have been needed. They've realised their error and made the replacement part much thicker. You would hope that the owner isn't having to shell out money for a failure in his machine that is hardly caused by wear and tear?

It was clearly cracked before painting - enough evidence there to claim a free replacement, even if it is well out of warranty. My experience with John Deere is not to hold out much hope there though.
Very true. But not really always that simple. In fact, it's never that simple.
All models will include approximations, to make them manageable to solve. All load cases will include assumptions, which may overlook something (not least how farmer Boggis *will* use the machine, rather than how he's *supposed* to use the machine).
There's a saying in engineering: all models are wrong, but some are useful.
The element of judgement required to select an appropriate model, and be aware of its limitations is why engineering is a skilled profession, rather than just a handle-turning exercise.

Post 497 - I don't believe it was, from what Kingfisher wrote, and from roughly measuring the two parts.

Well it’s coming off in the morning and they are going to see what they can do re-cost once spoken to John Deere, to be fair they replaced the other one last year on 7 year old machine at no cost, but said only side with unloading auger was at risk, obviously not!

There is nought like the hammering on a farm to find weak parts
But you would off thought if one side got replaced they would off done the other both nearly done same work unless it being going the same way round and round a field putting more stress on the outside one
All it needs is a drop off something or stuck in a rut/bog and twisted when pulling out to weaken it

Cast welding rods on that.

It’s not cast, you can see where the strengthener has been MIG welded on, doubt it’s just bog standard mild steel though!!!

It's a farm, not a quarry or something.
It can't be that difficult to predict how much load that track assembly will have to endure, taking worst case scenarios. Fully grain tank, auger out and full of grain, man's lunchbox and wife hanging on one set of steps. Full tank of fuel, a certain degree of slope. And so on.

Can send you a jarful of this if you want. Got more than I'll ever need, and should keep you going till you get a new tank

I feel your pain siding up Ready to re seed a field and a piece like that went though the back tire sidewall Plugged for now but it will have to be sent off for repair
Not today but about a week ago. cleaning off some steelwork for repainting, using a wire spider wheel on 4 inch angle grinder. Decided to play safe and wear leather gauntlets. Grinder hit a bit of metal and jumped out of my grasp before finding the top end of gauntlet and catching in the lining whereupon it travelled on down inside the glove shredding the lining and my wrist on the way, ending up as far as it could go with the switch totally inaccessible. Had to scrabble across the floor and pull plug from extension lead. Damage looked worse that it actually was thankfully and is healing nicely now. So much for Health and Safety, shall not bother next time!
