Just found this site and read all pages of this topic. I just moved from the city to this 25 acres in the sticks; I am new to tractors and just bought my first one, a Kubota
L3400, which I got mainly for brush/fire controll. I am learning to use the brush-hog and front loader, but have found it difficult to do any decent looking grading/smoothing with the loader bucket. I know that a Gannon would work better for that so I came to this thread to get educated, before I buy the wrong thing. After reading up here, I have a better idea what size I need...looks like a 5 to 6 footer; leaning toward the 5 since my property and roads are very hard and rocky with the sub surface rocks running from fist-size to car or even house-size. The larger ones kind of determine the grade, so I am stuck with surfaces that undulate left/right as well as up/down. Maybe I could build up the bad areas with fill dirt, but that's going to take a LOT of dirt. I am old and my remaining years are no doubt short, so should probably stick to filling in the water erosion channels so that a 2WD vehicle can manage.
My tractor doesn't have a hydraulic top link; just a manual turnbuckle. It doesn't have hydraulics for operating Gannon scarrifier/rippers either; is it worth adding the hydraulics, or is it even feasible?
