These parts are made to support the grass bag or box and position it correctly against the discharge chute.

Frequently Asked Questions
How do I choose the right collection box frame?
Match the frame to your Mountfield rear-collect machine using the model and serial number. That ensures the support suits the collector arrangement fitted to your machine.
Why does the frame need to seat correctly?
A correctly seated frame helps the bag or box sit properly against the chute. That supports a clean path for clippings to flow into the collector as intended.
Will one frame fit every Mountfield collector?
No, collection box frames and supports are matched to specific Mountfield rear-collect machines. Use the machine's model and serial number so the frame holds the collector in shape and lines up properly with the chute.
