My new to me 50 hour X580 was delivered this week. I upgraded from an x300 with bagger. moving to a bigger property and wanted the bigger tractor and also snow blower. I always bagged with the x300 and it did a great job. But the new yard is much larger and I’m hoping to get away from bagging if I can. It will be a ton of clippings to handle. Anyhow, I took a chance and had the mulch control kit installed on the 48A deck to see how it works. The dealer left the stock blades on the machine. part #M145476. They gave me the mulch blades that came with the kit but said to try the standard blades first. They said they have found customers having much better results with the standard blades and never using the blades that come with the kit. It seems odd to me but It’s a good dealer who always looks after me so I’m not concerned. It’s Too early to try it out here in Ontario just yet but was curious in the meantime if anyone has come across this scenario? I am skeptical on mulch control but thought I’d give it a shot. I kept my bagger frame from x300 so worst case I’ll buy the power flow and chute for the x580 and go back to that. But I’m hopeful I can live with mulch control.
