I agree,most Claas combines have them on all the time,NH hardly at all.Must be different header geometry.Never use them!!
On our downland soils they would pull barley up from the roots ahead of the knife and we can cut lower without them on.
Yep, that does seem to be the trend.I agree,most Claas combines have them on all the time,NH hardly at all.Must be different header geometry.
Lot’s of people have never altered the tines on the reel so it lifts the crop as a mat in front of the knife, loved the New Holland CX I drove for a few seasons for it’s ability to scrape stuff off the deck!Claas recommends them because they sell well. I've had barley stick on the tips of lifters and I only use them for flat crops. Try half spacing on part of the header as a trial and normal spacing on another part to see how you get on. Modern headers with tilting feeder house faces help a lot.
About spot on here I’d say my usual crops are standing with odd bits of N overlaps etc badger rolling etc I like the lifters as it enables me to run slightly higher and still lift the brackled stuff up going straight through the patches without messing too much with the reel as for and aft is a bit slow I find. But last year I cut some very very flat oats And had to take them off they were useless as they were doing there job too well lifting wet crap to the knife whereas the knife just cut through it and left the wet behindIt’s a tricky one. Not that sure if the lifters have helped me on my jd 800 series bed.
yes it is possible to lift the crop by moving the reel forward a bit and dropping it to rake the crop up and I do this on dead flat areas. I find the lifters can impede the flow of this mat onto the bed.
Where the crop isn’t flat but randomly brackled and short then I find I need the reel right back to help the crop come off the knife onto the auger. Putting the reel forward and down in this case seems too agressive on the crop and if I carry on raking like that then sooner or later I’ll pull a stone onto the bed. So I think in randomly brackled but not completely flat crops lifters serve a purpose. They also prevent a lot of soil coming onto the bed in the event of a bulldoze beginning under the bed. The heap of soil and straw cannot rise up through between the lifters very easily but can be seen there.
Yes the lifters are handy as they reach that bit lower than the fingers but if it’s dead flat and wet underneath they bring the whole wet mat up but it won’t flow onto the knife as it kind of impales on the lifters/ knife like sticking a fork in muck.About spot on here I’d say my usual crops are standing with odd bits of N overlaps etc badger rolling etc I like the lifters as it enables me to run slightly higher and still lift the brackled stuff up going straight through the patches without messing too much with the reel as for and aft is a bit slow I find.
