Gotta disagree on the tach thing. I think it is critically important. I don't know about you guys, but under a high strain (which is exactly when you want to know what the engine is doing) about all I can hear on my 1700 is whine from the HST, not engine noise, so I would find it impossible to accurately judge what my engine is doing without a tach. I use the tach to tell me if it is time to shift down from hi ot lo range, what rpm to warm it up at (Kubota specifically says to run at 50% of rated rpm during warmup - how can you do this without a tach?), and where to run it for loader work (again, my manual says to run 1700 - 2200 rpm for loader work, and I'll be darned if I can tell that by ear). If it is a $200 fix, no big deal. The lack of position control, however, can not be upgraded. For a while I was entertaining the thought of trading in the 1700 for a 2200, because it is lower to the ground and I thought it would be safer on hills. When I found out about the lack of PC, I decided to stay with the 1700 and just buy a tiltmeter.
