I am going to buy a new Exmark to mow my 6 acre yard. Home use only and need advice as to a couple option questions. Thank you. Here are my wants/needs: Want: Reliable tough unit that will last for years.(Overkill for my home use is good IMO) 60" cut most comfortable seat best engine option mulching kit Gas engine I was thinking the Exmark Lazer Z, X-Series would be my best option? Questions: If I go with the X-Series: Which engine is best with the 60" cut? Does the x-series come with the best deck? Does this come with the best seat or do I have to order that? Is the mulching kit OK, or would you advise against it?
