  • 11% more horsepower
  • Up to 12% faster cycle times
  • Upgraded hydraulic cylinders


Increased horsepower and machine stability

The 643L boasts significantly more horsepower for superb responsiveness. Unsurpassed power-to-weight ratio ensures steady multifunction performance in wet or hilly conditions.

Redesigned engine and equipment frame structures

Optimal weight distribution and longer wheelbase improve balance, for better stability when climbing hills and controlling trees. The 643L's wheelbase is 229-mm (9 in.) longer than their previous model.

Wide-open access to cooling package.

Cooling fan and other cooling system components swing out for quick and easy cleaning. Air-intake compartment is sealed off from the engine compartment to keep things cool.

The cab is 25-percent roomier and 50-percent quieter.

In addition to the larger cab size, the controls allow operators to configure joystick buttons to their own individualized preference. The optional joystick and foot controls deliver smooth, low-effort control to help reduce operator fatigue over long shifts.

Quick Dump for the disk saw felling head

New one-button Quick Dump opens both accumulating and grab arms, releasing trees from the pocket. Head-tilt and arm functions are combined into a single motion, minimizing fatigue.
