Common Use Case or Symptoms:

Use when the lower front panel is cracked or knocked out - this is the pane the operator looks through to set the bucket at the trench edge, and it sits low enough to catch everything the bucket throws back.

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?

  • Glass, Screws and Stoppers Included: Arrives with the fasteners, so the old hardware does not have to be salvaged off a broken pane.
  • Twenty-Eight Model Coverage: The widest fitment in the excavator group so far, running from the 311D LRR through the 325D.
  • Lower Front Sight Panel: The pane the operator actually looks through to place the bucket at the edge of a trench.
