I used my Frontier spreader for the first time to spread winter rye seed. I've had it a year or so, and have spread granular fertilizers and lime with no problems.
Spreading rye seed, I noticed that the flow of seed started to slow down as I went. Finally the seed stopped dropping completely, even with the spreader opening set to maximum. When I stuck my arm into the spreader (tractor off, of course) I felt a paste-like plug in the bottom of the spreader. When I dumped the rest of the seed out, the bottom of the spreader was coated with a material that looked like really hard peanut butter, and it had stopped up the openings. Some of it was so hard hat I had to resort to a chisel to flake it off.
I am assuming the agitator wheel was crushing the rye seeds against the metal wall of the spreader, and releasing oils that caused the problem.
Is this something that others have seen, and will removing the agitator wheel next time prevent it?
