• Note: Glass only - frame, hardware, and seals are not included. The M Series cab uses a different rear opening from the H Series. Measure the opening to confirm before ordering.

Common Use Case or Symptoms:

Use when the rear cab window is cracked or missing on an M Series grader - the operator spends most of the shift watching the moldboard behind them, so a damaged rear pane changes how the machine can be run.

⚠ Please Inspect Glass Upon Arrival: Glass items may experience breakage during transit. Before signing the Bill of Lading, thoroughly inspect all glass shipped via LTL Truck Freight. If delivered by UPS and found broken, contact us within 48 hours of delivery. Your prompt inspection is crucial for a smooth claims process.

Why Choose Broken Tractor?

• ✅ M Series Rear Pane: Distinct from the H Series rear glass - the M cab uses a different opening entirely, so the two do not interchange.
• ✅ Covers Series 2, 3 and AWD: Includes the 12M 3 AWD, 140M 3 AWD and 160M 3 AWD builds alongside the base machines.
• ✅ Frit-Edged 858 mm x 1129 mm: Published dimensions with the factory ceramic border, which is what the urethane needs to bond against.
