DEERE 643L-II Wheeled Feller Buncher Wheeled Feller Bunchers
Product Feature
Uptime
Simplified routing of the electrical and hydraulic systems improves reliability and eases service. Wiring and hoses are placed for protection against wear and damaging bends.
Stability
Optimal weight distribution and a long wheelbase combine to maximize stability when climbing hills while controlling the load. Durable heavy-duty axles help deliver stability and hill-climbing power under the toughest forest conditions.
Cab
Spacious and comfortable cab is extremely quiet. Large expanse of front glass provides virtually unobstructed visibility.
New Steering Sensors
New steering sensors control articulation speed when nearing frame-to-frame contact, cushioning impact during full articulation and improving operator comfort.
DEF Consumption
Exceptionally low diesel exhaust fluid (DEF) consumption rate reduces the need for DEF compared to some other EPA Final Tier 4/EU Stage V systems.
