Some say either one. Guessing you will get a set of wavy mulching blades with the mulch kit. Some love mulch kits, some hate them. I ran them for years until OCDC's came along. Biggest issue with a mulch kit is the loss of vacuum.
The Gator G6 is great for chopping up leaves. You can use the quik chute as a poor mans mulcher but you will generally have it pushing open slightly by itself from the material load. However at least for me in Northern grasses they leave way too many stragglers, so I stick with the stock JD high lift blades for actual mowing with side discharge.
I was referring more to skidding where wet or having a shore cave in under you type stuff. Not sure why this took so long to post. I hit the post button several hours ago.Nice thing with a stander is if does get too hairy just step off. No need to worry about being trapped upside down in a pond on a ztr or other horror scenarios. On significant slopes you can really climb over the machine to each side to adjust the center of gravity with your body weight.
