How about a new thread of the 9240 or 10240 machines
New Holland typically gets to launch first:Yes there is a 9240, what about a 10240, class 10 like New Holland.
On the 9240 is the grain bin still 350 bu?
Well...I dont think CaseIh will enter the class 10 til they change the cleaning system.
625 puts it solidly in the class 10 zone.The 9240 is available as a '15 model. It is a Tier 4B Final engine (15.9L). However, you will only see peak power of 625Hp @2000 Rpm is this platform.
Then why has there been HP improvements, cage improvements, cleaning system improvements?It's going to take more than just changing the cleaning system. The rotor has been maxed out since the 8010 came out.
It's limited to about 3,500 bu/hr @ 2% grain loss @ 180 bu/ac corn, which is 3.6 bu/ac loss. The CIH rotor and rotor cage physically does not have enough open area, or potential open area with the current cage design to to support anymore throughput.Then why has there been HP improvements, cage improvements, cleaning system improvements?
That little rotor can do over 6k an hour in corn. I bet CNH has had is closer to 7.5k in good corn. Dry corn hard to do with wet corn.
I am sure they are getting closer to maxing the rotor out. It probably is for small grains but I doubt it for corn.
I assume you've held a catch pan up to the straw door and verified that it wasn't rotor loss? 90% of our losses are rotor loss in most crops and conditions. This is measured with a catch pan with the chaff spreading and straw dropping. I've seen this on standard rotors and also small tube rotors.I sure don't see the rotor have much loses on small grains on our machines, and seives when set correctly do a good job overall, not over thrashing and chocking the cleaning system is the tricky part
Believe it or not,but there are areas in this world,where nothing but hp is needed to get some capacity out of a single rotor combine in small grains.People in the high yielding areas(140bu+) close to the shores of the north atlantic ocean or the baltic sea put chips in 600hp+ combines to keep em going in the evening when it gets tough...As they say, conditions vary. So some people very well could get 6000 bu/hr out of it.
Except for Gleaners, all combines are corn combines. That and soybeans. The ability to do small grains is secondary to most manufacturers. To me that's the problem with the horsepower race. It just doesn't buy anything for crops like wheat. In my conditions, heavy straw on irrigation, a class 7 machine is about ideal. We had a 7010 and loved it, and wrongly thought moving to a 8120 would give us even more capacity. We were wrong! In wheat, the 8120 had about the same capacity as the 7010, but burned a lot more fuel. So we now run a 7230 and a 7120.
