New MK4 with increased line pull

More rope capacity! 1800 ft

Proven two-drum winch chasis

New more powerful motors

70,000+ LBS LINE PULL at 3:1 Safety Factor

ADVANCED CONTROL SYSTEM

  • Remote start and stop of winch machine from tether machine
  • New compact, ergonomic screen
  • Upgraded control system with camera option
  • Enhanced radio system—never work out of signal range

REVERSED BUCKET

  • Right-angle operation – Work at right angles from the boom at full tension
  • Unparalleled holding force – Superior to competitors who rely on winch base weight alone

LOWER SWIVELING SHEAVE

  • Full-tension chain passage – Chains pass through sheaves under full tension
  • Reduced repositioning – Tether machine drives directly to the lower sheave under tension, minimizing winch base moves
  • Reduced winch base moves – Operator cuts more trees from one setup
  • Reduced sidewashing - Increases line pull and pulling power for slope maneuverability
  • Road efficiency – Tether machine leaves and returns to road under tension; only requires partial road width, keeping routes open for other traffic

TRANSIT MODE

  • Maintains low tension on lines during movement
  • Boom lifts and swings lines over obstacles without disconnecting from tether machine

SAFETY FEATURES

  • Dual-line redundancy – Two lines for enhanced safety
  • Over 70,000lbs pulling power at 3:1 safety factor
  • 230,000 lbs holding capacity when brakes are set
  • Designed for one-person operation
  • Superior radio and communication systems
  • Industry feedback: “Best system out there”

ADDITIONAL TETHER MACHINES

Lowest cost for additional tether machines - Only requires wire harness in additional units
