i can get a husqvarna zht4218 or gravely zt2050 for the same $, about 4800. Husqvarna is all comercial with fully baffled deck, and 18hp kaw. Gravely is commercial chasis, with briggs intek, and residential stamped deck. For 1.5 acres, which would cut the quickest, with the best quality of cut? Would it be the gravely, with the bigger deck. Or the husky with higher ground speed,and deeper deck? This is for home use. Any insight would be helpful. Thanks.
