S23 and S24 Lolium perenne and S37 and S143 Dactylis glomerata were cut to heights of 1 1/2 and 4 1/2 in. in a replicated experiment, using: a flail harvester, a reciprocating mower, and a reciprocating mower followed by a flail harvester to collect the wilted grass. At the short cutting height there was a marked depression of regrowth of all grasses following the use of the flail harvester (P<0.01), compared with the other mowing treatments. No such effect was observed at the higher level of cutting. Close cutting with a flail forage harvester was shown to be detrimental to regrowth, but the reasons for this effect are not clear.
