Thunderbird TY80 highlead yarder #Y8035. 1990 highlead machine, been sitting the last 15 years or better, going to need new airlines and probably new wiring, but the Cummins 855 runs like a champ. Been sitting on her thinking we would need it, but the torque converter on the Madill have been treating us better than the transmissions in the rock pit (would rather a converter stall than strand a mainline). Great gears, motor, transmission. Giver her some TLC and put it to work. Has a 3-drum tube, you could add one drum to the frame and make her a skyline machine, similar to a TTY-70 hoist but on rubber rather than tracks, and with a 100' tube.
