Turbo,
The ASV RC-100 is my dream machine. I'd love to outfit it with a Loftness Carbide cutter/Tushogg cutter/MagnumMulcher. Downside to the compact trackloaders is price. For the machine/cutter combo, I'd be looking at about $80K new. And finding an RC-100 used and in good shape is proving difficult.
But with a skid like that, I could still run grapples, augers, etc.
Have you seen the stuff from Geo-boy, Supertrak, Gyrotrac, Rowmec, etc? Purpose-built brush cutters. Really cool stuff. But again super expensive and not very versatile for other farm jobs.
