My local Deere dealer just totally quit carrying JD products. They went 100% with Kubota. I'm going to have to order blades on-line now, so can get whatever type I want. I have always used the standard OEM high-lift blades on my 717A 48" ZTR. I have the 2004 model with original 7-Iron deck. I exclusively mulch, and have the mulch kit installed. I cut a mix of common bermuda and tall fescue, and do oak leaves in the fall. With the 19 HP Kaw. engine, I am concerned about possibly bogging down/loss of power. Should I consider something besides the Gator mulchers? Anyone with the 717A have any input? Thanks!
