Just bid my first commercial account and I have a real good chance of getting the account. If I do I need a walkbehind that is very good on slopes. The slope is steep but can eaisly be walked on. Too steep for a Z, and if I slide I end up in the pond. So I think I need a walkbehind. Please make suggestions for WB's good on a slope. I am open for anything from a 36" up. I probably perfer one I can mount a sulkie so I can use it on other property, but 36 are eaiser to get to some of my backyards. No hurry, I dont start mowing this property till spring. The pond is less than 1/2 acre.
