Combines Straw spreading HElP PlEASE

[John_W]

Here is something that SDman posted sometime ago and I thought it was good enough to save. Disrupters should help break up and spread out the mat coming out of the rotor into the chopper too. CIH Straw spreader performance improvements from SDman. "Just thought I would share some tips to help maximize performance with factory chaff spreader attachments. We have several 36' MacDon heads out here and have a lot of no-till so even spreading of residue is a must. With just a few mods., and not a lot of money, you can make a stock Axial-Flow the best at spreading residue evenly. Here are 5 major points for proper setup. 1) Be sure you have the straw deflector in the discharge hood for even distribution to the spreaders. This deflector was added at 1997 production and can be installed in older machines and is adjustable. 2) Trim back about the last foot or so of the curtain on each side of the spreaders about were the curtain makes the first 30 degree turn. You might want to cut the curtain off and keep it in your shed so you can install them for row-crop harvest so cobs are not thrown towards the rear of the combine. 3) Install the fast speed spreader pulley (partn1994772C1, also requires spacer n27828R1),this increases spreader speed from 227 to 346 RPMs. 4) Set the spreader bats to aggressive position(this is shown in operator's manual but I see very few of them set this way) you might want to mark the spreaders Right or left so you do not get them mixed up when you remove them. 5) Case also came out with taller spreader bats that are taller than the factory ones. They recommend 3 of these bats on each spinner so that they alternate on the disc and that they alternate from each disc(short bat on lH spinner lines up with tall one on RH spinner, and vice-verse). The part ns for these are 321372A1 for lH on 88 series, 321373A1 for RH on 88 series; 323745A1 for lH on 44_66 series, and 323746A1 for RH on 44_66 series. These help spread tougher material such as green stem soybeans and help eliminate the "strip down the middle" that customers have complained about. With these simple mods, you will find these machines can spread evenly in most conditions."

John When you say straw deflector are you referring to the small straight vane, or the triangler shaped deflector with the rubber on the bottomIJ The reason I ask is because I too have trouble with more chaff on the right side and I read about the adjustable deflector, went and bought it put it on but then realized that it's not adjustable. So I think I got the wrong part. thanx Brad NC. IN.

you will have to add holes to angle pan for the adjustable deflector. but doin-t drill into fuel tank.

Something that you might also want to try and has become available since SDman posted this valuable information is the addition of curved bats for the spreader. Don't have the part number available in front of me, but have the parts man at your dealer check the combine performance catalog. If you try this you may not have to go to the speed up kit. If you already have the speed up kit you may have to place these in the retarded position in some applications under 30'.
