Nice site; I want to get a chain harrow to use for pastures and driveway. Looking at a 6ft 3pt from ABI Attachments. More than I though it would cost but looks like what I need. How does everyone like them?
Actually, I thought the $380 price for their 6-footer was pretty reasonable. Those things can be expensive. I like ABI's "chat" function, too. Pretty well-done website, IMO. Now if I could just get some of their toys ..
For pastures, the chain harrow would be great. In aggressive mode, it would scuff up the surface well for overseeding or general aeration. Quicker & much less aggressive than a disc harrow. In passive mode, the chain harrow would lightly cover most of the seed.
For driveways, I've seen about 4 or 5 different implements used: a box or scraper blade, a chain harrow, a landscape rake, and what EverythingAttachments calls a Land Plane or Land Leveler. Like everything else, the "best" one probably depends a lot on your surface material, how much of it you have to do, how good the operator is with a given attachment and how much time you want to spend at it. The box blade can do the job as could the chain harrow (if it's a dirt road or lightly graveled). The landscape rake I'm not too sure of; no experience with them but seems like it's not as aggressive a tool as the others. Could be wrong, though. Maybe those spring-steel tines are more aggressive than I think. The Land Plane is pricey but looks like a champ if road maintenance is your big need.
In any case, I personally believe a chain harrow's one of those tools that's worth having. It's just too handy a tool. That's me, though, and as is often said: YMMV (your mileage may vary)!
