I just picked up my Ecolawn and read about the slipplate.com graphite products to help prevent sticking. There are a bunch of products but the Ecolawn manual doesn't say which product it recommends. The first batch of compost I tried to use was a little moist and I was having major bridging issues. I also wanted to see which agitator you guys usually use for 3/8" screened compost. I've only used the agitator the unit came with installed so far.
