The cross members of the pallet will shave off the highs and deposit excess material in the lows..
Yup, Thats what I found as I pulled the pallet around. I could clearly see each individual board on the pallet was shaving a little at a time. When I'd get to a low spot, all the soil shavings would drop. The wider the pallet, the better the levelling effect. Weight to the rear of the pallet gave us the best result too.
I tried using an old railway sleeper first but that wasnt as effective. It had only one cutting edge and tended to ride up on the high spots.
You guys probably have seen these too, over here, they sell 3 point land levellers with the same principal as the pallet. Basically a heavy rectangular frame with 4-5 lengths of 3x3 angle iron as the shavers. Pull it around and it does the same thing. Very popular with horsey people for levelling sand arenas.
I just got an idea! We don't have a box blade but we do have plenty of pallets. Do you think we could use the pallet idea to smooth our our driveway? It is starting to get dips and hollows in it. It is gravel and appears well constructed most of it is almost like concrete so it appears the previuos owner built the driveway with all the right types of stones in the right order. Do you think the pallet idea couls smooth our our driveway?
Its worth a try... I dont know if it would bite into the compacted gravel but what the heck, it'd be worth dragging a pallet around to see?
My first method for levelling my gravel drive consisted of using a light spring tine rake with an 4ft piece of 9"X3" chained onto the back of the rake. The rake would cut in and loosen the compacted gravel and the wooden board would level things out behind. It worked very well.
I normally have a 3pt transport box fitted to the back of my tractor and I tend to use the bottom of that to level the drive these days. It is almost as good as the rake with the added benefit of carrying a load of gravel in the box as I drag it along just in case I need to fill a low spot some place...
