I have heard some negative things about that type implement, not necessarily a Plotmaster, but that type of implement. Lots of stuff there that can tear up. If you have well prepared soil they might work OK, but I don't think you can take unprepared areas and use them like the ads insinuate, especially grassy land and hard soils. Forless money I had rather have a good disc, a 3 point mount seed spreader and a drag harrow. Then you can use the disc for other uses, top off your plots with Ammo-nite or other fertilizers, etc. A 6 foot or so drag harrow behind a 4 wheeler will cover a plot up in no time and the seed won't be too deep.
