Any operators with any feed back on the machine. I actuially like the lay out of the NH and especially the size and operating weight of the 170. Im just woried the ROC is a little lower than I need. The machine will be a landscape machine, lots of bucket work and occasionally lifting pallets of sod(2000#) and stone(2500#). Is this possible or is the machine just to light? The 180 has just a little heavier operating weight than I want.
