ST504 Scraper Skid Adjustments

Hi Everyone,

Last night we got about 3-4" of snow, then some freezing rain on top. Made for some interesting conditions.

My Ariens is a 5HP. I tried making one pass, and realized that the heavy wet snow caused some issues. First, the scraper wasn't digging into the snow. It was "riding" on top of the snow. So I'm guessing that I either need a new scraper or need to make adjustments on the skids right? I was creeping along at speed setting 1.

Secondly, what snow I was clearing wasn't being thrown more than like 5-6 feet. I've been down the impeller kit road...don't think that's the real issue here. I haven't replaced the belts yet - which would improve performance right...? Mine seem quite loose and dry rotting.

Anyway, I'm maybe regretting a 5hp. Thinking of selling this unit for an 8 if I can get a good deal. I'm wondiering if that's the way to go afterall....

In heavy, wet snow, I use speed 1 or 2. Any faster and you are pulling in snow faster than the impeller can spit it out and you risk clogging your chute. My 4 hp Ariens 22000 will handle all snow conditions, but not at full speed. Your scraper blade will show signs of wear when it needs changing. If you are at the end of the blades adjustment slots and it is not performing as desired, it may be time to change her out. The skid shoes will adjust how high or low the scraper rides on the surface. On hard packed snow, the machine may tend to ride up on the snow if you go too fast. If your belts are loose and dry rotted...well, they aren't go to perform as needed. MH

If the bottom layer is packed down hard and is iced and crusty you will ride up regardless. The only fix for that is more weight on the front or to push forward / lift up on the handles.

Please direct all snow blower questions to the forums and not to me with PMs.
