On 8-11-07 I bought a new 07 grasshopper 723k mower w/ the 50" deck, and the 15 bushell bagger system. I have a little over 100hrs on it now, and thought I would do a little write up of how it is doing. So far I have not had any mechanical problems out of it. The bagger system w/ blower works really well. It will pick up just about anything that goes under the deck. The mower has a small fuel tank on it, but compared to my previouse mower it does far better on fuel. The only thing I am having difficulty w/ is tracktion on hills. The wieght of the bagger system puts the center of gravity over the back wheels, and not the drive wheels. I removed the rear counter weights, and it got better. I think w/ some wheel weights I can get my tracktion back on the hills. So far I would give this mower a high rating, and recommend it if some one was looking for a mower.
