I am trying to locate a grass collection system for my Toro Proline 120 Groundsmaster mower. I am really not wanting to contact my local dealer on this (personal reason) and wanted to see what options are available. The Toro collection system part# 30576 is one option and I wanted to see if anyone knows of other options to fit this model. Could someone here quote a price for Toro part #30576? Any help would be appreciated.
