tractor windows breaking

[multi power]

why do back windows break for no aparrent reason?
went ouer home yesterday n my tractor back window was smashed, aparrently nobody had been near it n tractor been parked a few weeks, i had replaced the same window a few years ago after it was broken when i came out one morning

i had similar with out 15, was out mowing all day, came home, stood her in the yard while i went in for some grub, came back out to find the window shattered but still clinging to the rubber.

just one of "those" things i guess

Either it has had a knock from a stone or something, or one of the hinges are bent putting stress on it when the window is closed?

bird flew in to it ?

A bit of a knock then the changing temperature makes the chip bigger, shattering it? Perhaps.

Plenty of big birds about...

Frameless windows are subject to bending stress. The gas struts are critical on some models of rear windows, because pulling to close, normally on the right hand side, causes the glass to twist. Some fit a less powerful strut on the left to counteract this, but these tend to be changed for non-genuine matched pairs with time.
Also the struts exert a significant force on the glass when the window is closed. This is a local twisting action from the struts trying to expand.

Add in changes in temperature and you have the occasional big bang. This is very common.

Yes,very annoying.

The new back window for our small Valmet remains unused in the shed as I refuse to fit it then it self explode.

Gets expensive when it is the third.

How do people find the new style 1 piece glass doors like nh, jd are using in the 4 post cabs? Any costly breakages? They do seem strong but it's a big lump of frameless glass and you need to have a good swing it shut them! I think for the LHS door it is a better idea to have the MF, Claas, Fendt door and find them easier to close and less likely to be bashed about

 

[grumpy]

the change to bonded windows wasnt the best of ideas there is zero give so changing temperatures is constantly stressing the window to the point it can be sat in shed and just shatter for no apparent reason.

 

[Cowabunga]

The bigger the door, the bigger the bang and the bigger the bill.

Apart from the risk of physical damage, it comes down to design. If they design and assemble the glass so that there is as little stress as possible, which means having accurate shut lines with not pinch points or improperly shimmed hinges and latches that are lined up properly and soft rubber buffers, barring shutting them on a stone or something, they should last indefinitely.

Trouble is, there's a lot of 'if' involved. At least they don't rust.

My MF 4255 door went with a bit of bang. God bless the NFU - the bill was nearly £700!

Don't you pay nearly that much insurance premium on it every year? For the sake of argument, say that you've had it for 15 years and paid an average of £400/year, that's £6000 you've paid for your £700 without even considering the investment income they've made from it. God bless them indeed.

You just love an argument, don't you?!

I wouldn't have it if it wasn't a legal requirement. It is, though, so it's nice to get something back. Especially when dealing with our local office - they are very helpful.

Keep it for best!

We have had two go on our ts115 in the last year, real pain, and it doesn't half shock you when they go bang.

Why don't they fit laminated glass in back windows?

Cos we bought it and I didn't get around to fitting it for a while and then thought 'why bother'.

It'll probably be fitted eventually when we sell it.

Sounds like the window fairy has visited.

Had a door on a Deere explode in a hail shower a few years ago,cab had been warm with heater on just before.
