Combines chaff spreading on the R series

[Westozzie]

I have an R60, fitted with the factory chaff spreader fins on the hinged panel above the shoe. We also no-till so need to get the chaff spread as evenly as possible. The original fins spreads ok to about 15 or 18 feet providing the wind is at 6 or 7. We have now fitted a Kirby as well. Chaff is now spread over most of the 30 foot width of cut. The factory chopper mashes the straw well, but the twin spinners spread it too much to the right. Any suggestionsIJ We have altered the advance and retard on both spinners, but just cant get enough straw to go to the left.

Make sure your dual spreaders are turning the right way. 4 paddle should be CCW as viewed from top and 2 paddle CW as viewed from top. Very easy to get belts on wrong thus wrong direction. Some of the channels on 2 paddle spreader have been fliped the wrong direction since they were built. Straw should be able to fall into channel with proper rotation of spreader. I presume you tried various speeds of spreader. You may be better off with slower speed rather than faster or the other way around. I think the small spreader is mostly responsible for spread to the left so take a close look at that. I did hear of a guy that controls spread from left to right with a panel in discharge chute to divert straw forward further ect. and that was for single spreader but may work equally as well for your dual spreader system.

Yes, Dan, I am that guy. I put another panel inside rear of discharge chute and can put material more foreward on the single spinner and can definitely spread plenty to the left. I have left panel set only about 1 to 2 inches foreward of original panel, and with 30 foot platform, I use two paddles fully advanced, and two cut off 2 or 3 inches and set mostly retarded. Spreads great when the wind doesn't blow much and goof up the throw of material. By the way, what is a Kirby chaff spreaderIJIJ Thought they only sold vacuum cleanersIJIJ I would like to spread the chaff better, but is not much of a factor as we do not do no-till.

The spreaders are turning in the correct way I think, with the straw landing in the channel of the spinners . I have only ever run them at full speed as described in the book for a 30 foot front - I will try slowing them down. The Kirby chaff spreader is made by Dutch Industries in Canada. It has a hydromotor driving a spinning paddle arrangement. We have added a seperate oil circuit to drive it, with the pump driven by a pulley placed on the end of the accelerator roller shaft, so that it goes whenever the machine is engaged.
