I also just bought a Scag 4/23/14, but I bought a Tiger Cat 52" with Kaw FX691V motor for $8000.00 after taxes. I mow 4.5 acres that is hilly and was worried I bought to small but have to say I'm impressed. Never drove a zero turn before and haven't mowed this year (grass between 5-9 inch) till I brought it home. I asked for some hearing protection for Christmas sense I cut wood for supplemental heat and ended up getting a pair of Howard Leight AM/FM radio ear muffs. So put about 2.5 gal. of gas in each side, put on my ear protection and took off. First I was going to go around the house (being lazy) then thought I'll just do the front yard (went pretty fast) then might as well do the back. Radio said rain tomorrow so I'll go around the barn, well might as well do the other half of the property where I planted 40 trees 5 years ago. It probably took 2hrs (guessing) not knowing what i was doing (I looked like Tony Stewart on a dirt track coming around those trees) grass was high in areas but never bogged down and yard has no clumps at all, amazing. I did use one side of the gas tanks ( full throttle @ 2hr stopping to pick up branches over 2" diameter) Now I'm looking at fertilizing my yard where before thought I couldn't keep up with the growth, lol. Man you all probably know but the hearing protection really made a difference ( I had a apple tree rake them off my ear once and couldn't wait to get them back in place). Really am impressed with the power, speed, and quality of cut with this unit.
