cord,
hate to be a stick in the mud . . . . but here goes, fertilizer can be caustic to painted metal frames. for longevity i'd look for a stainless frame. i've owned earth way spreaders in the past, and due to my laziness in not cleaning them thorouughly, they rusted and became inoperable.
i learned from some heavy equipment operators to coat the exposed parts in diesel fuel . . . now they tell me! i was also talked out of a front mounted spreader for the front of my kubota bx (caustic materials / salt & fertilizers, once again).
i mentioned in a previous post, i need to powder coat the tph parts that are not already stainless. hind sight is 20/20 . . . i should have gone with a "HERD, rear mounted spreader" they make a model for your atv.
good luck and good hunting
