More Power for Better Production
The new J-Series wheeled feller buncher features the emission-compliant John Deere 6068H engine, with increased horsepower to 174 on the 643J. In addition dramatically increasing the machine’s multi-functioning capabilities and cycle times, the power increase makes operators measurably more productive.

Productivity of the J-Series is undaunted by steep slope conditions thanks to the improved tilt-back geometry on the head and better load transfer capabilities. The result is a more stable machine.

Comfort All Around
The new J-Series machines not only set the standard in operator comfort, but the new forward-sloping windshield and larger skylight provide unsurpassed visibility as well. Best-in-class serviceability access, with the tilt cab, full-service access panels and hinged rear grill, makes maintenance on the new 643J feller buncher a breeze.
