Just bought a MiniFastrac 16/42 2 weeks ago. What an awesome machine! Although, I'm just a residential mower, this site has helped me a lot in determining not only whether or not to buy a ZTR but which one. My only problem with it is I can't keep my 12 year old son from mowing the lawn. The maneuvarability and speed is fantastic, and the cut is unbelievable. Friends and neighbors have come over and commented on how good our lawn looks. We're currently mowing our lawn (17,000 s.f.) in 3 different patterns, couldn't do this with a lawn tractor, in half the time. Will be planting field grass on the rest of our property this fall, can't wait to mow in the spring! P.J., I want to compliment you on your professionalism and expertise on responding to posts and problems on this site. I have just one question. Are fusion blades on my Mini and what is the part number to get a spare set? Serial # 05052046. Also, we bought from Longmont Farm Supply, they just started selling Hustlers about 5 months ago and were great to deal with. Great product and well worth the money.
