Common Use Case or Symptoms:

Use when the lower front pane is cracked - it is the window a grader operator looks through to watch the blade edge meet the grade, and it sits low enough to catch stone kicked up off the moldboard.

⚠ 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?

• ✅ Laminated Lower Front at 6.9 mm: Bonded glass low on the front, facing the moldboard and everything it throws back at the cab.
• ✅ H and K Series Cut: 821 mm x 584 mm, a distinctly different size from the G and H Series lower front pane, part 1505105.
• ✅ Reaches the 16GC and K Series: Covers the 120K, 140K and 160K alongside the H Series machines on one number.
