I'm looking to add a mulching blade to my 42" Rear Discharge (Model 78350). I would like to stack the mulching blade above the regular blade like this (picture is not mine):
I can't find a mulching bladewith the same specs as the Toro blade (Part # 106635).
Length = 14 1/2"
Width = 2"
C.H. Diameter = 3/4"
Thickness = 0.2040"
The Oregon 90-643 G3 Gator blade is close.
Length = 13 7/8"
Width = 2.5"
C.H. Diameter = 3/4"
Thickness = 0.203"
Will the difference in blade length cause any problems? It seems like everything would still be balanced on the spindle and the Toro blade would still allow a full 42" cutting path. Am I missing anything? I have not verified that there is enough spindle length to accept both blades, but it appears this hasn't been an issue for others.
