First let me apologize for ever posting on this site that 1/4 acre lawns didn't need a lazer!!! A ZTR what ever brand is worth the money. My thread is to give a review of my purchase . Exmark lazer Zhp 52" trivantage deck with 23hp Kohler. I have been able to cut in dry grass and wet tall grass with one pass. I have one 1 acre lawn that had wet tall grass and it cut one pass at full speed with the deflector up and dispersed very nicely. I have the same deck on myWBs and striping is good even without a roller. There is no bogging down of the Kohler in the tall wet grass. I am able to cut at least 1 to 2 more lawns in the same time as my walkbehinds and the fatigue factor is way down. The lazer requires a greater concentration level but the floating deck makes cutting almost idiot proof. The worst part is operator error in making the zero turn ( wheel marks in the grass)and that is solved by a bag of grass seed and a simple explanation to my customers of a break in period for the new machine and my skill level. NO complaints as I had feared any many seem mezmerized with the machine . I chose the exmark as its reputation proceded itself and the HP model is smaller for my size lawns. Just the deck height adjustment alone goes a long way to reduce opperator fatigue vs constant changing of shims on my fixed deck walkbehinds. I have OCDCs on my walkbehinds but with a lazer you can just cut backwards so that install (OCDC) may wait until next season. I don't have any experience with other ZTRs so my opinions are only of this model . I can say that the stiff price tag of $6799 seems miles away as each evening I am less tired and making more $ per HR. I am very happy with the controls and opperation of my mower and was even happier I could fit it and a 36" toro WB parked sideways on my 5X10 trailer. "gitcha one if ya' kin"
