Common Use Case or Symptoms:

Use when the left side window is cracked or has been taped - it sits on the operator's entry side where the cab gets climbed into daily, and once starred it will not survive long under a grader's vibration.

⚠ 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?

• ✅ Left Side Counterpart: The identical 791 mm x 1473 mm cut opposite part 3001874, so a matched pair can be ordered together.
• ✅ Four Pounds Lighter Than the Right: A quick way to confirm you have the correct side out of the crate before anyone starts fitting.
• ✅ Blends With the Existing Cab Glass: Factory light green tint at 70 percent transmittance, so one replaced pane does not read differently from the rest of the cab.
