Subject: Case 875 vs. JD 2730



WC Iowa		Which one does a better job as far as turning the field with heavy residue black and leaving the least amount of ridges. Currently run a Krause Dominator 21' and have had excellent results other than turning the field black. Raise a fair amount of COC and feel we need to bury more residue without making another pass with a disk. Machine durability is also important. Heavy frame not apt to crack and reliable performance with minimal breakdowns. Hopefully one or both will perform mechanically as well as our Dominator has. TIA

Central IL		Not much experience on the Deere but the 875 will leave it smoother.

If you really want to turn it blacker, look at the Sunflower 4630. It has 28" blades up front individually mounted. It will pull harder because it's working the blades deeper. It also has a heavier frame and walking tandems across main frame and the wings using the wide semi tires. The biggest downfall the Sunflower has is hp needed to pull it and no scrapers on the blades when the soil is wet and tacky.

NE SD		I run a 870 and neighbors run a 2730 and we both have rolling baskets on back and farm next to each other. The blackness is nearly identical imo. But the 870 definitely leaves ground smoother. I love the 870 but it does have its share of maintenance and repairs. There is a lot of moving parts on it.

NC Iowa		I've had all three. Nothing will get it blacker than a 2730. If you have enough horsepower to put the disc in the ground. Its the only thing I have ever seen where the disc blades will just keep going deeper and deeper. If you have your shanks set at 10" depth with a 9560RT and 11 shanks, the disc is really the limiting thing on horsepower. If you take all the collars off and bury the disc it will slow you down to nothing but it will make it almost as black as plowing. If you want to keep your speed at 5.5 to 6 you'll have to set the disc at a reasonable depth like 3 or 4 inches which then makes it comparable to an 875. The leveling is better on the case ih, it will leave it smoother no matter how you try to set the john deere. This is in heavy black dirt. If you are in a different part of the country, someone might be able to go 7 mph at 14 inches. I've never really liked the shanks on the deere. It doesn't seem like there is any sweep forward to them like the dominator or case ih. The points on the other two are pointed forward a little bit, and might do a little bit of lift and twist. The deere is like the point is facing downward and basically like dragging a stump underground.

WC Iowa		I have heard there can be some issues with bolts breaking, coming loose, ect on the 870. I was under the impression the 875 remedied a few of these issues. I could be wrong. What is the difference between the 870 and 875 other than the ability to hydraulicly raise the rolling basket?

cropsey, il 61731		Ok I'll go outside the box - an old earthmaster with new blades set aggressively will make it pretty black (or it has for me in the past). To some extent a shank is a shank if it able to be at the correct working depth (not talking about wings, etc). You can add things to the back to make it smoother, but I'm not sold on leaving ground field finisher smooth in the winter (roughness could stop some erosion and allow more water entry into the soil profile to freeze later, etc).
