St. Louis Equipment stocks and carries the X-Blade Dual Mulching Blade D’ttach Manufacturing.
The X-Blade adaptor turns your mower into a grass and leaf mulching monster. The X Blade allows you to run two blades on each spindle, giving you double the mulching ability out of your mower.
The X-Blade Dual Mulching Blade Adapter holds your original blade and an additional mulching blade at a perfect 90 degree angle. Your original blade (lower) will give the clean height of cut and the mulching blade (above), with multiple cutting edges, pulverizes the cut grass as it cycles through the deck chamber dramatically reducing grass clipping size.
Available in 3 sizes to fit most commercial mower blades:
XB 2.5 W x 5/8 CH (most common blade size)
XBE 2.5 W x 15/16 CH (Exmark/Toro mowers with a spline* see picture below also can be used with 5/8″ CH blade)
XBP 3 W x 15/16 CH (most 3″ wide commercial blade with 15/16″ CH or 5/8″ CH)
$33 for a set of 3.
