So, I've been looking at zero turn mowers for a couple years. I have between 3 and 6 acres to mow, depending on what I let grow up as field grass, a billion trees and lots of slopes/hills. I have been using a very old RX75 (36" deck riding mower) we unaffectionately call the "John Fawn". It's old and slow, but it gets the job done as the time spent mowing approaches infinity. My youngest son loves mowing and has adopted the mowing job. The time spent mowing is golden time to him (he's autistic and riding a mower is one of his "things").
OK, the time spent mowing is valuable to him but mowing every night of the week is taxing regardless who is mowing and the RX75 isn't getting any newer. We had been looking for a 72" deck machine since we cleared the land with the need to mow it with the brush hog, most trees remaining are spaced for that (lots of room). Anyway, an offer I couldn't refuse was made to me for a 960M during a chance trip to my dealer for a missing bolt/washer/nut in my ballast box extension kit last week.
Somehow I walked out with a Ztrak too. The pic is from taking delivery the next day.
Yes it has Tweels, or what ever they're called... I'm the kid with the funny handle bars on his bike. The deal was for a floor model that wasn't moving it came with the tweels and run-flat fronts ('might as well be steel casters). It did come with the high end suspension seat which is very nice and my 72" deck (+ a 31HP kawi engine). I have mowed with it but have no contrast to draw from for comparison as I haven't mowed with pneumatics on a zero turn before. Its better than a RX75 I'll tell ya that... Its fast and nimble, boat loads of power and holds to my hills w/out issue.
My buddy who runs a lawn care business was here last night and took it for a ride. He really liked it. He said the tweels did nothing for the ride that his machine didn't already do ("I can't tell the difference", was his response on the tweels). But over all he was very positive on the machine. He runs Scags, only Scags.
First mowing was over 3x faster than the little john fawn - and we had no idea what we were doing. It will be even more significant as the learning curve is flattened. The new green machine sits next to the big tractor in the barn, which is currently curing its ballast box cement. Man, they get hot! 160F on the oven Tstat was the peak (medium-one according to the Tstat). I hosed the case down until it was cold again after the pick. It's currently about 140F. Sugar slowed the start of the cure, but after it got going...wow.
