Combines How much BS is involvedIJ

[twinscrew]

A bunch of BS is involved if someone is trying to tell you any STS will do more acres than 2 8820's. That's assuming both 8820's are running and not under repair. Most 20+ year old combines aren't the most reliable. I'd even bet that a bright shiney new STS couldn't keep up with two good running 7720's. The STS would catch up when the old machines needed attention though.

Any rotor is going to have much more through put than a conventional because of straw walkers. Rotors are much more forgiving on loses and do a much better job of cleaning with less damage. It would be tough to compare a conventional to a rotor unless all these issues are addressed in various crops. Conventionals are good machines but limited in capacity because of the walker loses, You can only load those walkers so much before it starts rolling out the back. Not certian I would try to compare the two, maybe a very small rotor against a large horse rotor

one thing about it, there is almost no such thing as not being able to combine tough beans with an STS, you can go alot earlier in the morning with a STS. Ive seen someone combine in the rain, until it got to heavy it wouldnt unload. Not saying that was a good idea though

A STS and CTS will do as much 2 8820s in good barley and high yielding wheat. Something to do with straw walkers vs rotors.

Been there and done that and its no BS. In light crops it probably wouldn't be true but in good barley and 50+ wheat with lots of straw, the STS or any other rotor will walk over the 8820. Also, 20+ year old combines can be very reliable if taken care of. One of our combines is a 8820 with 3,800 hrs and it has been just as much reliable as our newer machines.

Good post. Some people still don't know the difference between a rotor and conventional.

Turn the power up on the 8820s to the same as the sts and put spikes and disrupters in to get the straw in the same condition as the sts then compare again. The rotor style seperator takes a lot of power to run. The power is consumed in the breaking up of the straw as it trys to force the grain out. I'd say comparing a rotor with a conventional is a lot like apples and oranges. To truely and fairly compare the two I think you need to give them both the same power and ability to create the same conditions of straw for seperation. If you took all the teeth off the rotor and made it so the straw was kept long and lowered the power to that of the compared conventional, I doubt you'd see the increase in capacity. But ya, it is amazing what a high horespower rotor can do compared to a stock older walker machine. Most case operators say the 2388 will do the same as 2 older 1680s, but it wont unless the conditions are such that horsepower is the only determining factor. I've been running an old navistart powered 1680 long shoe in the same field as a 2001 2388 for 4 years now and I will out do the 2388. The reason is I have modified the 1680 and the 2388 is bone stock. The grass seed we run in requires cleaning capacity not power. I have increased my cleaning capacity and as such can out run the high horsepower non modified 2388. But, if we were to go to a crop needing power and not cleaning, I'd be sitting there getting dizzy (dizzier watching the 2388 run circles around me. So all in all, I think the crops being ran and the requirements of those crops should be looked at before a deffinate comparison answer can be had. Am I too far out of bounds on thatIJ

lol....you should modify the 2388 That way you have the cab lol last time i checked the a_c worked a lil better and overall it was a tad nicer haha Good post thou

Cab and ac work fine on the 1680. Bells and whistles dont pay the bills here, they just create more. The 2388 is a custom hire machine we hire to help us out. If they were to "upgrade" their machine, yes it would stay right with me. And, perhaps if the windrow were to get rained on, it would pass me. It better, the payments are higher

"Bells and whistles dont pay the bills here, they just create more." Truer words were never spoken. I wish the manufacturers would catch on to this fact.
