Having a hard time finding Hustler blades online. any suggestions? Looking for blade number 797696. went to my dealer to pick up a few sets and they were almost $15. I know you can find them online cheaper. Hope you can help. these are hi-lift blades. What type of lift do you guys recommend for discharge only mowing of fescue, bermuda, and centipede. In the winter I use my walker to vaccum up leaves. didn't know if a different "lift" would cut better or last longer. Any other blade suggestions?
