I have had my 5610 for about 9 months and 125 hours. I continue to make a few mods to it. My last couple of mods made recently were major and still in the "testing" phase. Had one repair to the tilt control valve due to a tree spade that was probably too heavy and far out the front. It was covered under warranty. Everything else has been operating normally. I really like the machine overall. Graded, moved dirt, buried concrete, moved rock, tilled and planted a yard for friend a few weeks ago. Was about 2.5 acres. The "tool of all trades" did a really good job. It excelled at all tasks but one compared to a CUT. The ground was hard and dry. The hydraulic operated pto showed its weakness compared to a CUT. Just not as much pto hp. On a CUT, the pto hp increases as rpms drop into the torque range. On the TC, the pto hp is max at 540 and then it is all downhill. If till into a tough spot, it just bogs down and stops the tiller unless you slow way down or raise the tiller. No need for a slipclutch or shear pin on pto attachments with the TC. Otherwise is was better in all aspects compare to prior Kubota 3710 and current JD 3720.
Grading with box blade requires skill, but the TC makes it a little more challenging. The independant suspension will sink and rise slightly as the box blade is raised and lowered. This makes controlling the depth more difficult. Especially noticed when trying to acheive the perfect contour to a yard. It would probably be very frustrating to a newbie operating a box blade. Just have to be aware of the difference and adjust accordingly. The hydraulic rear cylinder of the TC does allow slight raising and lowering adjustments to be done easier than a CUT which is sometimes more jerky and with larger movements of the 3pt.
I buried some left over concrete, cement blocks, etc. The TC with bucket teeth, dug really well. Much better than a CUT with toothbar. I was down 4-5 feet without much trouble. I think this is due to its 5600 lbs, all 4 WD and better visibility. The digging conditions were perfect with nice moist black dirt in an open field. I believe bucket teeth also dig better than a bolt on tooth bar that I used in the past on CUTs. Bolt on tooth bar creates a thicker lip and may hinder digging compared to teeth bolted to the cutting edge.
I tilled about 2 acres and the hydraulics were used a lot. Absolutely no heating issues. The temp gauge stayed in the lower range in +90F temps.
