I'm planning on jumping into fertilizing/pesticides next year and the spreader i have now just doesn't work well for larger lawns because it doesnt' throw it out evenly. I was looking at Earthway ones that i would be able to mount on the front of my mower. Does anyone use one or have one similar. I was looking at this one http://www.earthway-outlet.com/m21.htm ...but possibly this one http://www.earthway-outlet.com/m40.htm because it switch control. Any input would be greatly appreciated!
