just came across this site tonight, Fri. 11:30 pm calif. Very cool and full of great info. I'm an official horticulturalist and have a small maintenance and installation business in Malibu. I just picked up a new acct. that's got a huge lawn!I have one single speed honda and one three speed honda and it takes close to two hours to complete the lawns! my big question is if i were to purchase a commercial mower, which has the fastest walk behind speed? and what would be my next step up as far as buying equipement to get through this job faster? I can't afford these 5000 rigs, but would spend around 1500 if something had a bigger deck and cut my time down.
