Chico:
I have found the primary key to using a box blade to be the length of the toplink. Shortening the toplink will tip the box forward, causing the front blade to dig in for digging and moving dirt. Lengthening the toplink until both the front and rear blades contact level ground at the same time is good for moving loose material from one place to another without digging. Slowly lifting the 3-pt hitch as you are moving will spread the material, while lifting the hitch quickly will leave a pile. Finally, lengthening the toplink until the rear blade contacts the ground first and the front blade is slightly off the ground is best for leveling and final smoothing.
If you are using the teeth (scarifiers) to loosen the material before you move it, the length of the toplink will also control how deep the teeth dig, in addition to the settings on the teeth - down to dig, up to smooth or move material.
Lastly, it is probably best to take small bites, rather than trying to move the whole hill in one scoop. For the final leveling/smoothing operation, traveling in circles, figure 8's, "walking ovals" or some other method of hitting all of the area from a number of different angles will help to move material from the high spots and drop it into the low spots.
Takes, a lot of practice, but hey - seat time is good, right? /forums/images/graemlins/wink.gif /forums/images/graemlins/grin.gif
