dont buy the ones from lowes either! They were terrible. The trimmers spun around so much as i was going down the road. it almost damaged the throttle trigger on one of them.
I got a rack from my local Ag Supply retailer and they work great for only like $120.
Dont be fooled by lowes $75 racks. Theyre horrible.
