I'm looking to add a velkie to my 36 in Snapper walk behind. Can't decide between the one or two wheel. I'm concerned about the wheel mark the one wheeler may leave down the middle, my dealer said "no big deal looks like two 18 in. cuts if even that noticeable." Does the two wheeler limit mobility and speed in the turns? Will the two wheeler whip or jacknife or tear up grass in the turn? What do you guys think is the better option? Thanks for any feedback!
