Follow up on the new Cub Cadet Z turn:
I think I made the right choice of tool and its specs. Since getting used to operating it I am definitely getting the job done faster and the cut looks way better than the rotary cutter. And now, instead of spending 30-40 minutes behind a push mower I can get the actual yard part done in less than 10 minutes on the ZT and about 5 minutes with the push mower to get the tight spots.
Power, deck width, tires, features, speed, comfort, operation etc are just right.
So I got the right tool for the job. It remains to be seen if I got the right brand. A couple of thoughts on that. First, Cub Cadet advertises that their stuff is made in the US. That's relatively important to me. But as with most such claims, it is only a little bit true. The tires are Carlisle and say made in China on the sides. I'm assuming the Kawasaki engine is made in Japan (of course JD and Kubota use Kawasaki engines as well). The hydro units say "Assembled in the US". So presumably those parts are made in China and put together here. Anyway, I don't like that sort of advertising or outsourcing but both seem to be standard practices regardless of the brand.
Second, the ride was rough. Tolerable but not great and it worried me some. Then I saw a video where the owner of the same model was doing his first maintenance interval and found that the rear tires had 30 psi in them and that the sidewall says maximum of 10 psi. He said they are shipped that way for some reason. I checked mine: 30 psi. Dropped them down to 10 and it makes a huge difference. Smoother ride. Better traction too. Problem solved.
Third, the cut is so-so in my not-quite-field but not-quite-lawn areas. These are grassy but with lots of leggy weeds mixed in. These areas are also rough-ish. I've noticed a fair amount of stragglers sticking up even if I mow slow. No big deal. Still looks worlds better than the rotary cutter. On the actual lawn the cut is great.
Fourth, mower belt somehow came off and I mowed for about a minute with it running on the middle spindle shaft rather than the spindle pulley. The belt is now very frayed. Not sure how, when or why it came off. It is likely I did something wrong. I know I engaged the PTO with the engine on low throttle once and I might have even cranked it or shut it down with it engaged. Not sure. In any case, it was easy to get back on and it has mowed for 2 hours with no problems since then.
The dealer and manual recommend oil change after first 5 hours so I'll put a new belt on it when I do that.
Bottom line, if the unit remains reliable then I will have lucked out and will be pleased with the purchase.
