What John Deere glass does this windshield replace?
This windshield replaces John Deere glass #T312628.
Which E Series machines use this windshield?
This windshield fits supported E Series machines with serial 269401 and below. E Series machines with serial 269402 and above use the later G-style windshield.
How can I tell which windshield my E Series machine needs?
Check the machine serial number first. You can also compare your existing windshield and mounting-hole arrangement with the fitment diagram included in the product photos.
What thicknesses are available?
Choose from 1/4″, 3/8″, or 1/2″ polycarbonate.
Is tint available?
Yes. Tint is available with the 1/2″ windshield.
How dark is the tint?
SHIELDS specifies the tinted polycarbonate at 50% light transmission.
Is the tint an applied film?
No. The tint is part of the polycarbonate material rather than an applied film.
What is the SHIELDS Seal?
The 1/2″ version comes with SHIELDS’ purpose-built gasket already installed while retaining the drop-in replacement design.
Do the 1/4″ and 3/8″ versions include the SHIELDS Seal?
No. The SHIELDS Seal is used with the 1/2″ windshield.
Can I continue using my windshield wiper?
Yes. SUPERCOAT is applied to both sides for abrasion resistance during normal windshield-wiper use and cleaning.
Can I reuse my original hardware?
Yes. The windshield is formed and machined around the supported factory mounting locations so the original hardware can be reused.
Is this windshield ballistic-rated or certified for operator protection?
No. This windshield does not carry a ballistic rating or a guarantee of bodily protection for a particular application.
Note: Compatibility depends on your machine using John Deere glass #T312628. For E Series machines, this windshield is for serial 269401 and below. E Series machines with serial 269402 and above use the later G-style windshield. Always verify your machine’s glass #, serial number, and mounting configuration before ordering.
