Common Use Case or Symptoms:

Use when the upper door pane is cracked - it sits at eye level in the door, so a crack there is directly across the operator's view when working alongside a curb or a windrow.

⚠ 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?

• ✅ Either Upper Door: One pane covers the left or the right upper cab door across the whole H Series.
• ✅ Includes the 24H: Coverage reaches Caterpillar's largest motor grader, which most replacement listings leave off entirely.
• ✅ Lightest Grader Pane Here: At 11.3 lbs it ships by ground service and fits without a second person.
