I put spikes over the grates just yesterday. I use these in Bentgrass and they seem to help break up the mat of straw better. Bentgrass is very small though at 8 million seeds per pound and doesn't come off easily.
I used spike bars in last seasons corn and soybean harvest but I use them with disrupter lugs and that combination work very well for me. I was mostly after something to tear up soybean stems.
We run the spiked bars over the full rotor in our 1680 and 2188 for rice. They use more Hp but seem to chop the straw and handle slug feeding from picking up down rice much better than the non-spiked bars. The ones we use are chrome plated Hershels I believe. A local dealer carries them and they are cheaper than Case nonplated bars and last twice as long.
yep, it's definitely worth putting these on, they reduce rotor loss by loosening up the straw when it gets back there and shake out that xtra bit of grain, we ran one header with them last season and two without and the two without were loosing more over the rotor
You are killing your productivity running straights in edibles. Spikes will bust up that crop mat in soys and move some of that wrapping mog in edibles. One other thing you can do is add an additional kicker in front of the existing one. You might be able to get away with retarding the vanes in corn and leaving the spikes on year around. I always end up getting more cob in the sample when using spikes and round bars. Remember kill stalls (the intentional kind) are priceless when it comes to evaluating your combines performance. Good luck
I have found that spiked rasps in place of the straight bars and the installation of an Estes disruptor package made all the difference in the world. So far does not seem to be a problem with rotor loss in corn and really smoothed things out in soys and edibles. I have been leaving the machine this way with the vanes in the stock-middle position. I got the package from my local Case dealer. Watch you don't put a spiked rasp in the concave area unless you re-adjust the concave stops. My neighbour learned the hard way and notched the rear concave with the spike. The disruptors appear to keep the crop mat more open and actually improves separation especially when conditions are on the green side. I still keep a close eye on the grain loss monitor.
My grates in my combine are a custom made round bar grate, similar to the ones in the STS Deere. I don't think the disrupters would fit this grate. Can I run without the disrupters IJIJ Should I do the entire area over the grates with the spiked bars or just the places where the straight bars were IJIJIJ
The 8010's for 2006 had all straight bars removed and spiked rasps put in their place on corn_bean machines. Rice version combines for years now have had full spiked rasps in the separating area of the rotor. Rice is a damp green crop when harvested from what I understand so be careful in dry conditions with this setup. Watch rotor losses as material flow through the system will be faster with a full set of spikes in the rear
