Hi everyone, I'm new on this board. I'm from Montreal, Canada. My mowers are all Kubota ZD-21 with 60'' deck. This summer, I think I will trade one of these for a ZD-28 with 72'' deck. I got too much contracts and I have to find a way to cut faster. Do you think that 72'' is too wide and will scalp the ground? I need your suggestions. I trade it tomorrow. Thx a lot!
