I think NH stands for New Holland.I too am looking for info from people who are knowledgable about flail mowers.I`m looking for something to cut my food plots that does a nice job and doesnt butcher the clover and leave clumps and wheel tracks.I`ve used rotory "butcher" type pull behind mowers and have not been very satisfied with the results.What model and size NH mower is Moonstruck using?what can a guy expect to pay for one of these?
