Ancillary main frame parts include the handle and drive control bar, engine pulley, grass catcher bag, catcher frame and mulcher plug. The mulcher plug is a moving part that mulches material cut by the mower as it is transferred through the chute to the grass bag. Other main frame parts include all the nuts, bolts, screws and washers need to affix all of these pieces to one another.

Wheel Assembly Parts

Wheel assembly on the Craftsman 91737764 includes the mower’s four wheels and all the parts required to attach the wheels to the main frame. Wheel assembly parts include all the nuts, bolts, washers and screws needed to affix the wheels to the main frame. Other parts include a dust shroud that protects the engine and blades from being invaded with dust produced by the mower’s motion, wheel pinions, brackets and the V-belt. A connecting rod anchors all of the wheels together so that they move in unison as the unit is manually moved forward.
