42 Side and RD decks

[gregg.d250 0]

Are the following mower blade part #s good for both the SD and RD decks?

106636

106077

16636

13 27/32" Length

3/4" Hole Size

I was thinking of trying out a set of Gator Blades on a WH deck. I've had good results with Gators on other mowing decks and thought I'd give them a try if they are interchangeable between the SD and RD decks. By length and center hole diameter, it seems they are..... but caveat emptor!!

Thanks-

The difference between the side and rear discharge blades is that the rear discharge has less lift on the backside than the side discharge because they discharge the clippings differently. The side discharge deck has to blow the clippings out of the chute where the rear has to blow nothing so has less lift on the backside[possibly to save some power as well]. Good luck B)

I believe there is also a difference in length....

SD ones are................shorter 13.5"

RD ones are................longer 14.25"

roughly......
