Haymaster Trail Mower


Kosch Company offers four models of the Haymaster pitmanless sickle bar mower. The HM7 is a single bar trail mower with a 7-foot sickle bar. The HM9 is a single bar trail mower with a 9-foot sickle bar. The HM3P7 and HM3P9 are 3-point mounted mowers with a 7-foot and 9-foot sickle bar respectfully.

The pitmanless drive gives extended maintenance free field hours. Down time and maintenance costs are reduced by the reduction in the number of moving parts. Cutting knives are available with top serrated or under serrated sections.

The Haymaster is equipped with the SCH Pro-Drive Knife Drive. This drive has absolute linear knifehead movement with no loss of stroke and is nearly maintenance free. The drive runs quiet because all moving parts are always in rotation.
