I have a NH 355 but you need a bare minimum of 60 hp to get anything done with it. The main problem I find with this model is it's hopper tank. It's not a particularly effective mixer as I find a lot of stuff bridges in the void at the top of the cone where it meets the wall. A straight wall mixer with a wide sweep vertical mixing auger would work a lot better... As far as the rest of the machine goes... it's OK for moderate use. It's got a lot of open bevel gears and jaw clutches that will no doubt take a dump sooner or later.
