I have been in the residential lawn care business for about 5-6 years now and am quoting on more midsize lawns (1 - 2.5 acres). The dealer who I have worked with for several years, and who has never led me astray is telling me to go with a 33" Billy Goat walk behind mower. I have never heard of Billy Goat before and have a few questions for other professionals: 1) Are they durable and reliable? Do they last a long time under a commercial workload? 2) How are they for fuel consumption? 3) What is the quality of cut like? 4) How are they in thick or wet grass with and without the mulch kit? Can't think of anything else right now but I'd really like to hear from someone who has used one of these over a long period of time and who knows this machine inside and out. Thanks in advance.
