So how many cross bars of railway iron on that, Blanch...just one at the front and one at the back, or several in between? Were the sides railway iron as well?Best one I've used Lynas was about 45ft wide and about 35 ft deep and the track was up side down bit the wheel runs on was on the ground.
Work amazingly well in our Qld melon holes.
That sounds a lot like an experience a young relation of mine once had. The Boss had just finished explaining to him in great detail, how to use the soil leveling bar, and that he had to be very careful, because it was a very wide machine and had a tendency to drift around. The Boss then set off in the tractor to demonstrate the procedure to the lad, who watched on in a sort of bemused horror, as the leveller tore up about 200 yards of brand new fence.For us they work best at high speeds... had to be careful on the headlands as you could wipe out posts as you turned around.
That idea with the wide seeder is a good one. We just call them smudgers around here and use them for levelling paddocks out that have been pugged up by cattle and spread the cattle crap around. We have one made out of railway iron which is made in a H frame and we end tow it around and it leaves a horrid mess everywhere.Over here, they are called "Smudge Bars", and are used most often for incorporating clay.
I built some a few years back - just a couple 20ft lengths of railway iron, one behind the other with chains welded on joining the two together. The railway iron is pulled on its side, with the big side to the front. On both lengths, weld the pulling point at the bottom of the front face. This way the leading edge leans back a bit, which helps the dirt to 'flow' over the top.
This design is cheap, simple and quick, but a hassle to transport, and if you get stuck, you end tow out and leave a mess to clean up later. How well they 'bite' depends of a few factors (size/weight of the railway iron, wet/dry soil, soft/hard etc.). I borrowed a set made of heavier H iron and they moved a lot more dirt than my set did. Also got stuck a few times with them!
The best ones I've used, I borrowed from a contractor.
They were made from the frame of a gutted shearer 40 row wideseeder, with two rows of railway iron welded into the frame. It was great to use, because it had plenty of wheels, plenty of weight, hydraulic up/down, 2 sections for better contour following, and end tow for going down the road.
