I was looking into a commercial unit to replace my Crapsman DSG6500 garden tractor with a Scag ZT Turf Tiger, I have about under 3 acres of grass and a few trees.. mainly flat land.. residential property.. my current Crapsman with the Kohler courage 27hp bogs down under wet grass from the morning dew and chutes out clumps when mowing the lawn, tried all type of blades.. this mower is only good mowing at 2mph... it's not made for mowing more than 1 acre, plus I only get 1 solid good cut on a 4 gallon tank.. I've finally saved up to get get a zt mower.. any one running the big block in their turf tiger? How many cuts can I get out off the BB on the TT
