How Strong is the JD Cab's Glass

[MF1652]

Talk to anyone working an orchard. Cab windows will break if hit just right. My father runs a MF383 with a Laurin cab. Every piece of glass has been replaced at least once while spraying the orchards. And it gets pricey.

I would bet there are cab companies where the glass fairs better than others and probably has some to do with how they are insulated in the frame.

The cab door I mentioned on the prior page was on a Laurin cab. I think that their glass is as good as most found on cab tractors today. You can break any of them though. all you have to do is be unlucky for a moment.

Norm Crosby would be proud of you.

Unless you purposely chose to use a malaprop here, the word you're looking for is ornithologist.

I don't get it. You've offered evidence that's pretty clearly outside the normal experience range of many who've responded so far. But there's not one single malicious post. A few have experienced the opposite, a few have posted good natured jest.

Why can't you accept that not everybody has the same tractor with the same glass that contributed to your bird experience. And I have to state again, this topic was originally and specifically addressed to the John Deere 3000/4000 series cabs. As has been said more than once, all tractor cab glass is not created equal.

So. Since you clearly feel you're being picked on, is there a persecution complex involved here or what?

Lighten up.

Safety glass will break easily if it hit near an edge. The guy that puts up hay for me has a John Deere with a window broken out. Rock strike from a mower. I have driven several cab tractors with windows broken. Don't know how they were broken. Several people drove those.

Actually it pretty much is. The only real difference as far as breakage goes is going to be the shape, (curvature) of it and how it is installed as in is it glued in or installed with a rubber gasket. If you were to take the glass out and look at the edge of it, it will all be pretty much the same, It's either tempered or laminated, all the laminated is going to be pretty much the same and all the tempered is going to be very close to the same. It's not like they use x strength glass in JD and xx strength glass in Kubota. They all will have x strength glass.

Well - technically - tempered glass is not equal to laminated glass. But clearly I should have been more specific. How about this? Not all glass tractor cabs are created equal.

But truthfully, I never even realized there was such a thing as tempered glass in a tractor cab. I thought it was all laminated, like automotive windshields. That said, I'm going to once again try to steer the discussion back to the OP question regarding the laminated glass in the JD3000/4000 series cabs.

Greg, never said that tempered was equal to laminated, I said that the cabs have both, just like a vehicle, laminated in the windshield and tempered every where else. I think that you will find that in your JD cab that it has laminated glass in the windshield and tempered in all the rest. I assure you that your doors are not laminated glass. Laminated glass as does any annealed glass looses a lot of it's strength once a hole is drilled in it or that it has a notch put in it. Look at the logo on the glass in the lower corner of the glass. It will say if it is laminated or tempered.

Tempered laminated is possible, but very expensive and not very common. I think that BMW-AMGs have tempered laminated in their side and back windows.

Glass will break.

Everyone,

I was wondering how strong the JD's 3000/4000 series' Cab's glass was? How large of a branch could whack the glass before it breaks? Any idea what the cost would be to replace the glass if it breaks? Has anyone ever had this unfortunate issue happen? I know one of the farmers down the street was on his 4320 last year brush hogging and a stone/small rock flipped up, hit the back window and broke it; needless to say, he was not happy.

I don't know about JD's cab glass ,but that was a worry for me when I got my kubota . I ended up getting Insurance with Kubota and if i break one it's $250 deductible no matter what hits it ...rock ,limb, or bird.
Reminded me of when the farmer where I worked was mowing and came back with the back window broke out , glass all though the cab and even had some cuts on his arms. He said he picked up a rock when mowing. He had it replaced and one day not to long after that while just getting out of his cab shut the door and walked away when we heard it blow out, or I should say in. When we cleaned out the glass around the window gasket we found a few small stones between the frame and where the gasket went. He thought maybe there were in there when the new window was put in ,maybe not , but it sounded like a gun going off .
