But maybe we're onto something....a PTO powered disk harrow! Why leave a simple and effective tool alone when we can use technology to make it more.......complicated.
deere755, the disk works great. I suspect heavy pull type disks are even better but for small food plots a 3 pt hitch model is better because it allows you to turn around in smaller spaces.
The disk I have is a a 7 footer. My tractor has 45 hp and 4wd and it does fine but the disk does work the tractor pretty hard, depending on the soil condition. It is still wet here and I could not disk several of my plots because they were too muddy. Even then, the tractor could pull it through, just very slowly. Some of the plots were just right. Even so, I normally ended up in a gear (usually 3rd (3/lo)) with the rpms up pretty high. Where you really notice the tractor working is the fuel guage. Compared to mowing, disking or plowing just sucks the fuel down.
This disk weighs right at 800 pounds, which is about as big as my tractor (which is very light for a 45 hp) can handle. I suspect that when it dries out here, this disk will barely scratch the surface. But, I have a two bottom plow and what I've done so far is plow first and then disk. This really works amazingly well and my very poor, rock/clay soil actually starts looking pretty good after plowing and several passes with the disk.
