At the beginning of the season I bought an Earthway 2150T tow behind spreader. It works good for the most part (I'm mostly just glad I don't have to walk behind a spreader now) but I'm noticing a problem with material not getting emptied out of the hopper as it gets low. The agitator is just a 2" long pin that sits about 1/2" above the bottom of the hopper. When any material gets below the agitator, even if there is still enough material to cover the bottom of the hopper, it either no longer comes out or not as fast. I have to keep stopping and physically push whatever is left toward the drop holes. This gets mighty irritating as I have a hard time spreading that little bit left toward the end of the spreading. I have read mixed reviews on Earthway (but also mixed on Lesco, Scotts etc..) so I don't want to give up on it. Due to a disability I can only use a tow behind spreader so that limits my options and I'm not spending $400 for a better quality one. Is there something else I can do like spraying the hopper with no stick spray so it slides down toward the drop holes better or rig up a better agitator?
