Combines sts sample

Slow the thing down! rotor 6-800 concave 6-10 seives adjust to the conditions, fan 8-1000, even if you have the big bar concave take out those inserts. Most of this I learned last year from a operator harvesting food grade beans and seed corn. Told me he couldn't get a decent sample without running it on the ground so tried a lot of different settings that sound way out of the "box". I got home and tried it and it works perfect. Will put grain samples against anyone. No loss of capacity or ground speed and nothing---nothing out the back. In corn this year I ran 1-3 on the concave and as slow as the rotor would go (without drive belts slipping) to 450 rpm. fan wide open, sieves, top 12, bottom 6. Again I left out all concave fillers, solid and bar type. 6 mph, 150 bushel corn, 18% moisture, 12R 20" Geringhoff roto-disc head. Was running in four wheel drive so speed was limited to 6-6.2 mph. Enough blow'in. Run her slow and tight was the best tip I ever got.

If you are harvesting wheat that has been frosted and or, drought affected, you will have trouble - no matter what colour machine. This is what I have found runs OK in hard wheats. Rotor about 830-880, concave 7-12, top sieve 16mm, bottom seive 6mm (make sure the indicators are calibrated correctly) fan 1050-1080. Biggest problem with these machines is the non adjustable pre-cleaner. It is designed for corn and works well in corn. Absolutely useles in low yielding canola or wheat. There is an adjustable one from JD or loewen. This year I had plenty of problems in crops that had been frosted then had a very tight finish. Ask your mates who may own other colours how they are getting onIJ If they're honest with themselves they will also admit it has been a very tough year to keep grain in the machine.

We have a 2188 here in Australia, and l must agree with Rod that the crop conditions were hopeless this year for header setup couldnt keep the stuff in the machine. Even demoed the 9860 JD to see how they would go didnt seem to be to different. Do you like your sts I have been thinking about changing coloursIJ

We run a TR99 with a 36 ft honey bee in the vic mallee (Australia) crops this year varied from 2 to 20 bags _ acre never had a problem with grain loss we run the rotors at full speed (1500rpm)top riddle wide open the bottom one closed up only enough to get an acceptable sample striping up to 44 tonne per hour in the good crop 32 to 35 most of the time. Did some contracting with cts 2 with 36 mc don admit cts has more hours (3000)but were very disapointed with is capasity same size box but I could get 3 boxes to cts 2 all day no probs also run with a N7 with 30 ft lots of hours could out strip it easy he then hired a R72 (3000+hours)36ft mcdon could keep up with it til about 15 16 bags an acre then it just had the edge. But for reliability I wouldent go past a TR even with the same hours. Just my experences this harvest over 4000 acres.

To Aussie jr. yes i like the sts,found it to be very reliable. capacity and sample in barley, canola and fabas is exellent.up to 50 ton in barley but wheat if you want capacity sample is ordinary. just cant get rid of chaff. seive area is too small for what the rotor can handle.sts is very popular in our area of SA.finding that you have to hold material in the rotor as long as you can.thanks to other replies you learn something every day.
