I have been talking to several LCO owners and others about mowers lately. I have about 15 accounts and used a JD tractor and some homeowner crap this year. Id like a ZTR but I know I cant really afford it with the money I have (I also need to get my trimmer, blower, etc outta this $4K). One guy told me that with the walk behind you cant keep up with it walking after 2nd gear. Is this true? I wouldnt mind having a sulky but I dont know if the wb could pull my big ass (6'5 325 lbs). Any advice is apprecated.
