I have a S330 with VTS tracks and the forestry app kit and thier Mulcher, along with a Davco brush cutter. My question is who makes the drum and carbide hammers for their mulcher ?? I know Fecon makes the frame etc but the drum and hammers look like the drum from a Loftness G2 cutter, why I'm asking is I need a little more productivity and was thinking the Planar blades from the G2 may be better. The pump is modified so I got tons of power just need a little more grunt from the cutter.
