I owned a 61" Turf Tiger for 17 years and had almost zero problems with it. The only replacement parts were deck spindles, and obviously blades and front tires. I used it to mow about 3-4 acres of fairly rough and often dusty "lawn" in TX. Moved to WI, to a smaller acreage so left the TT behind, and replaced it with a JD 48" Z355R zero turn. By comparison, it is somewhat flimsy and a lightweight, but I understand it is a consumer model whereas the Skag is a commercial mower, costing 4X as much. However, in the first 20 hours, I had 3 warranty items that needed attention; since then it has been OK. The other thing that really irritates me is that there is a front lift arm that squeaks constantly. The manual even acknowledges that this will happen and advises lubrication to "prevent or minimize" squeaking. Fer cryin' out loud, JD engineers couldn't figure out a simple way to prevent this with teflon fittings, for example?? Shameful. Also, below 50 degrees it is difficult to start, and the service center can't do anything about it, says they are all like that. (I REALLY have never liked Briggs engines.) Using 91 octane non-corn-juice gas, by the way.
No, would not buy a JD consumer model again.
