Chain harrows can also be used on loam to sandy soils.

Chain harrows generally have spikes on one side and are plain on the other.

Chain harrows are often used for lighter work such as levelling the tilth or covering seed.

"Chain harrows wouldn't shift it so the dried slurry was killing the grass underneath.

So impressed is John Ryder of the University Farms at Aber that he says he cannot envisage using chain harrows again.

Seed should be sown through a ' V-ring' roller drill and lightly covered with chain harrows, and rolled again (except on strong clay soils prone to 'caking').

There are four general types of harrows: disc harrows, tine harrows (including spring-tooth harrows, drag harrows, and spike harrows), chain harrows, and chain-disk harrows.

They almost always consist of a rigid frame that holds discs, teeth, linked chains, or other means of moving soil-but tine and chain harrows are often only supported by a bar at the front of the set.

His chain harrows weren't breaking up the slurry crust either so he had bought an OPICO grass harrow and was very pleased with it. "We're only about four miles from the OPICO factory so I phoned them and they brought one over for me to try."
