About this product
John Deere 85D and 85G Polycarbonate Cab Door
Replace the left-hand entry-door glass on a John Deere 85D or 85G excavator with a clear 1/4-inch polycarbonate panel made around the original door pattern. This panel replaces John Deere glass number 4684428.
The listing is for the glazing panel only. The door frame, seal, hinges, handles, latches, wiper parts, and mounting hardware are not included.
Confirm the door before ordering
John Deere identifies 4684428 as a door for the 85D and 85G. This SSC listing is limited to those two Deere models and the left-hand cab entry position. Check the machine plate and the number tied to the existing door before checkout, especially if the cab has been replaced or repaired.
Is the current panel an upper windshield or lower windshield rather than the entry door? Does the machine carry a Hitachi model plate? Use the exact model and glass number rather than relying on shape alone, or send the serial number and cab photos through our contact page.
Material and finish
The panel is cut from 1/4-inch clear polycarbonate for the 4684428 door pattern. Polycarbonate handles impact differently from tempered glass and is a practical choice around brush, limbs, mowing debris, and other work that repeatedly breaks cab glass.
The surface still needs the right care. Flush away grit before wiping, wash with mild soap and water, and use a soft cloth. Do not use ammonia-based glass cleaners, solvents, scrapers, or abrasive pads that are not approved for polycarbonate.
Installation checks
Plan to transfer serviceable OEM hardware and the door seal from the existing assembly. Inspect the frame, seal channel, hinges, latch, and fasteners before disassembly. A bent frame or worn hardware can keep a correctly cut panel from aligning and sealing properly.
Need original-style tempered glass or the separate upper and lower front panels instead? Contact SSC with the glass number and machine serial number so the correct public product can be confirmed before ordering.
