Today I demoed an Exmark Metro 36 inch on my backyard. The owner of the local Exmark store brought it over and was shocked to see the grade of my yard. I live in a relatively high-end neighborhood, so you think the builders would of done a great job, but the company that graded the yard left lots of bumps and dips. As a result, the ground is not smooth. For example, in some areas the grass blade is six inches in length, while in other areas it is two inches in length. This shows you how deep some dips are in the yard. I had it built last August, so you think the builders would fix the problem, but my neighbor fought them (same builder) for a long time to fix his water drainage issue. Is there anything I can do to correct the problem? Would hiring someone with a riding mower who can tow a heavy-duty roller to come over to roll out the bumps and dips work? Any help would be great.
