I have owned my RSD for a few weeks now and overall I am very impressed with the machine. The power, handling and cut quality have been outstanding. My biggest complaint with the machine has been the rattles and noises. 1) I know Hustler is looking at the clutch rattle situation already and there is another thread started so I'll leave that one alone for now. 2) I had a low hollow plastic type noise that was most obvious at low RPM. At first I suspected the air filter cover but I found it was actually the filter itself vibrating against the bottom of the housing it sits in. I rectified this with a small piece of foam rubber attached under the filter to absorb the impact. Works great 3) I identified metallic rattle coming from the right side of the machine. After feeling around I found it was the deck catch. The metal piece that catches the deck when you put it all the way up in the transport position. There are 4 thick washer and the bracket on this mount with A LOT of slop. For a quick fix I installed a rubber washer from a garden hose I had laying around. It provide just enough compression to keep the noise down but still allows the lever to fall into place when you raise the deck x2 4) The final adjustment I made was to the discharge chute. I felt like it was pointing too far down with the outer edge dragging in the grass if I was cutting the grass over 3". I don't like the idea of bypassing this safety feature with a bungee cord and holding it all the way up. On my old mower I had tried to hold the chute partially up with a bungee and found it bounced a lot. Instead, I came up with the idea of installing a bolt as shown in the picture. I belive the bolt is a 5/16" and it actually threaded in perfect. By adjusting the bolt in and out I was able to get the chute raise about 1.5" and my clumping problems are gone! I am afraid the bolt will start to wear into the edge of chute from the vibration so I am looking at reinforcing that edge with a thin piece of sheet metal or shim stock. x3 I am not sure if these ideas are new. maybe someone else has something similiar, or better, in place. For now these are working for me.
