forterra doors keep smashing

my 10641 keeps smashing its doors when its parked up, 2nd one is after smashing while parked up in yard with all doors and windows closed.
What is causing this, will zetor cover it. it is an 08 model i bought last year

Does your dealer sell you NEW replacement glass doors, or old stock ? they had issues with hardening, the dealer better throw away any old ones.

I have an 08 forterra 10641 too. about 4 years ago I came out one morning to find the right hand door smashed on the floor. the tractor was in the my garage, windows and doors closed, it haven`t been used for a few days.no idea what happened, hadn`t been doing anything mad with it.my local Zetor dealer fitted a new one, grand since. my tractor insurance paid for the replacing and fitting costs
