In 2012 when I needed to replace my tractor I looked at new Kubota. I was planning on running a rototiller on the back of it(1.5 mph operation) so would need creep gears. I was planning on financing through Kubota and they ended up impossible, so dropped that plan. Ended up with a used 2008 John Deere Premium tractor with IVT transmission. It has been a good fit, but there are so many sensors that can throw off alerts, some of which will put the tractor into lame duck mode. I am able to find some of the error codes on the internet now, but in 2012 when I got the tractor I would call the service department. Once it was flashing a code and shutting me down and I called the service manager. He looked it up and it had to do with the right brake. He had never seen that code, but thought maybe there was some dirt in a sensor(micro switch). Told me to stomp on the right brake a few times to see if that cleared it. It did, but that is how sensitive some of those systems are. I had another issue one time with the tiller on the back. I really needed to finish up, but it kept de-rating my operation due to over temperature, but my monitor showed 175 degrees. Finally by the time I finished I was down to 0.2 mph. Stopped by the dealership and the service manager knew exactly what was happening as it had happened to a sod farm on their bat wing mower tractor. The tractor has basically two cooling systems that use the same radiator and the coolant had gotten low and one side had gotten some air, but the monitor was only showing the one side at 175 degrees, but when it switched to check the other side, it was too much of a differential, but it didn't show me that. The service manager printed out the bleed instructions so I could take care of it. Point being, good relationship with your service manager can save money and trips to the shop.
