Maybe it is because it is new, but my
B2650 does not emit an audible whine over the sound of the engine in low range at all, in mid range only if it is over-loaded and struggling do you hear it over the engine, and in high range you absolutely hear it. But it is not something bothersome, it is just a sound that the machine makes. Now, if you want to hear a whine, get on my Craftsman with the Hydro Gear G730, that makes some noise if going up a hill. But even that is not a bother, it's just the sound that a hydraulic system under load makes. I guess I don't understand why it is such a big deal for some of us that a machine emits a sound? My guns make sound, my truck makes sound, my tractor makes sound. The dead raccoon at the end of street is totally silent. No sound. But it's not a machine.
