The biggest issue is lack of capacity which is what I am thinking is leading to a lot of cracks and splits. Right now it is set up with a full set of steep pitch helicals and a bison rotor. The problem is that I can only go 2 to 2.5 mph taking in 30 foot of beans windrowed with a Pickett one step and am running out of power. The vines do not seem to be flowing thru the cage properly and are being carried around and being ground up. If I speed the rotor up to about 450rms then things flow better but the beans get really bad. The first year I ran it with steep pitch helicals and a original style sunnybrook rotor with some homemade sweeps on it. Capacity was very poor as lots of rotor rumble would occur if I pushed it. The last 2 years I ran it with the Bison rotor and that eliminated the rotor rumble but used a lot of power. This year I changed the tines on the Bison to more of a flag shape to try and move the crop mat along faster. Hasn't been working any better and I ended up blowing up the cage. Found a good used cage from an R65 and did a bunch of reinforcing to it. Also put in a new set of steep pitch helicals. Did about 70 acres with it and the rotor gearbox blew up. Pulled the rotor out and the new helicals are already worn about 40% plus in spots. I did talk to Dan a while back and he suggested that I try a different rotor but I am not looking forward to putting another 10k into this old machine in hopes of getting it to work the way I feel it is capable of. Anyone have some suggestions? Thanks for the replies thus far.
Sounds a little like what I experienced this season. Now, mines a 95' Deutz powered R52, did all the processor mods, rear feed floor, the whole works. I'm clipping blacks with a 520 flex head and air bar. When beans were 18-20% and had been desiccated a week, the vines were still tough and the engine would pull down bad enough for the alarm to go off. Generally couldn't go much faster then 1,5 to 2.0 mph. Rotor was at 210, but pulled down to 180 or so when bad. Did bump the rotor speed up to 250 and that helped a bunch, but then bean moisture fell to 14% and the vines stayed tough, so had to drop my rotor speed to save on splits. Ground speed was still abysmally slow. Yield was very good, so lots of beans to separate from the MOG as well.
So your problem leads me to ask if you're trying to stuff 30' of tough stuff too fast? What's the moisture of the beans and what's your sample look like? Lot of trash, besides splits? Maybe, with the conditions you're faced with 15' instead of 30' might be a better option. You'd certainly be able to move faster and keep the combine full.
Just guessing from however many miles away, but blown cages and wrecked gear boxes sure sound like you're trying to stuff 3# of material in a 2# bag. |
