Just bought a new 36" Viking on Thursday. Great machine, only problem is the rear wheels are too low. The manual makes it look very easy to adjust the axle position. Is it as easy as it looks? I'll probably need to do this soon. Some of the thick, spongy lawns looked scalped in spots. Right now axle is set at position B, looks like A is the lowest and E the highest setting. Otherwise, I'm enjoying the hydro- it rules!
