Common Use Case or Symptoms:

Use when a rear side pane is cracked - a grader operator turns constantly to watch the moldboard and the ripper, so the rear side glass is in the working sightline rather than being an occasional glance.

⚠ 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 Rear Side Opening: One pane covers the left or the right rear side on the H Series cab, so there is no handedness to specify.
• ✅ Eighteen H Series Builds: Includes every NA and ES variant, which is exactly where grader fitment usually goes wrong.
• ✅ Under Twenty Pounds: Small enough to ship by ground service and to set into the frame without a helper.
