I have had a 455 now for 7 years and I am getting long in tooth. Tilling a garden with a troybilt and a bad knee is no longer fun. I was thinking of picking up a 355 and a tiller for it to make my life easier and gardening career longer. How noisy is a 355d? I had a 2 cyl Satoh diesel and didn't care for the resonance. I have to cut 2 acres and the 60 inch deck on the 455 makes quick work of it. The 355 has a smaller deck. I would be selling the 455 with a snow blade so would likely have some change due. Tilllers for 455 are dear, while those for 3 series tractor are half the coin.
