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
