At one of my accounts, sod was put down 4 weeks ago. I let the grass grow for 2 weeks then cut it with my 21" Snapper so I don't damage the sod. The sod has been there for a total of 4 weeks now and I am wondering, how long until I can cut the new sod with my 48" Bob-Cat WB (which I love!!!!!!!!), without damaging it? Thanks in advance.
