An excellent option to original factory installed blades on John Deere Models 145, 155C, D140, D150 and D155. Gator mulching mower blades are the ultimate in lawn mower blades, Gator Mulching blades are uniquely designed to direct grass clippings back into the cutting path resulting in finer grass clippings for quicker decomposition. Gator Mulching blades do not require a mulching kit therefore they are more user friendly than mulching kits which can produce clumping if too much of the grass blade is cut off. These brand new, uninstalled, first quality blades are MADE IN THE USA!
These Gator blades will replace John Deere part numbers GX21784 and GX21785.
The blades are 17.675" long with a 7 point star shaped hole in the center.
