This is related to the 28 acre account I may be getting to also keep it maintained. Along with this account, I am also getting an account in March to cut about 2 acres. It is a mobile home lot (new homes for sale). I currently only have a 1996 Walker GHS with a 36" deck. Good mower but it has some age and it's not quite as reliable as I would like it to be with these bigger jobs coming up. In my area I have dealers for Toro, Husquvarna (sp?), Walker, Exmark, and John Deere. Right now I am mainly looking at a Exmark 52" or 60" Lazer Z S or X Series? Is it worth the extra money for the X Series? Also EFI or no? I will be renting a Exmark 60" next week so that will give me some seat time on one to see how I actually like it or don't. Thanks for the advice and help!
