It’s interesting to note the loss distribution of this S780 in rice. And before there’s a pile on of criticism about John Deere rotor loss ……. you can get a similar result for many machines, if they’re pushed too fast & not setup to suit. In this test, this machine was doing 6k’s, pushing 9mtrs …. in 11t/ha rice @ 19-20% moisture.   |

No criticism from this deere combine fan! Really its more to deal with understanding the working of the equipment than labeling a brand. I am pretty happy with both the 9760 and s 680. I used to run two twin rotor newhollands and they harvested a great looking sample but I would say it was no better for grain loss.
Is there more grain loss with dryer rice? 19 to 20 seems pretty tough?

The lower the moisture level you harvest at, the higher the brokens & therefore lower whole grains ….. equals lower income.
Best if it’s harvested at 19-22% …….. but that’s harder to reduce losses. Compromise !

The videos I have watched of rice harvesting look like there is a bit of green material going through, not the easiest to reduce rotor loss in that situation.
So is this just where the spreader places the loss Rod? I know when I used to run CaseIH the competitive product specialists knew exactly where to throw the pan to make my machine look bad, there was a typical loss pattern for that machine.

Yes, rice can be one of the “life skills improvement” crops for not only the operator but the machine! The straw is green, & there’s plenty of it, plus you have high yields (12-16t/ha) & moisture in the grain …… 18-22%. And it’s even more interesting if it falls on the ground ……… sometimes in the mud!
As far as I’m aware, all machines have their “signature loss” patterns. Usually, Case & JD are more pronounced on the RHS …….. all depends upon rotor speed & concave clearance, plus how far the chopper/spreader throws it & the weather conditions. NH mostly throw losses both sides pretty even……. but not always.
The new Case with HarvestCommand seems to throw (rotor losses) more evenly as the position the material leaves the rotor is different now.
I now use up to 9 trays set across the swath width (12mt) to provide a better understanding of where the problem is …… if there is a problem. Trays dropped right behind the machine with the chopper/spreader going will tell you SFA! Multiple trays dropped off either sides of the back of the “header”- with the chopper/spreader going flat stick, will provide pretty good information of loss distribution.
I maybe a bit OCD in this area …… but it’s just interesting to see what each machine does in different crops.
Always amuses me when people are scratching around on the ground directly behind a machine to determine loss acceptability …… with the chopper going flat stick. It ain’t there! It’s 3 to 6 plus metres either side of centre.

When checking behind the gleaner when you are combine right beside a low road there will be nothing in the stubble,the losses will be dead Center on the road.
