Harvesting Track Feller Bunchers

541 Series 2/552 Series 2 — Full Tail SwingTrack Feller Buncher Features: ● Cat C9 ACERT Tier 3/Stage IIIA/Japan 2006 (Tier 3) equivalent high torque engine provides excellent power, fuel economy, serviceability and durability. ● The most robust tilt mechanism in the industry, the tilt- ing model (552 Series 2) have a patented 3-cylinder tilt mechanism with simultaneous tilting forward and side-to-side. ● Proven rugged undercarriage designed for the tough- est harvesting conditions ranging from wet bottom- lands to steep rocky slopes. ● Hydraulically actuated dual service door provides engine/ hydraulic access direct from the cab. ● Walk through service access minimizes service time and down time costs. ● Comfortable, purpose built forestry cab with heavy duty guarding meets FOPS/ROPS/OPS and OR/OSHA requirements. ● Optional hydraulic packages are available for opera- tion with an intermittent saw or a high speed disc saw. ● Felling heads utilize high pressure hydraulics and proven components to meet your application requirements. ● IQAN display allows the operator to continuously monitor the machine and get early warning for poten- tial problems. ● Ergonomically located pedals with side-by-side foot rests provide maximum operator comfort when the machine is traveling. ● Flexaire fan (standard) allows the cooling fan to purge debris from the radiator area minimizing cooling sys- tem maintenance. ● Hydraulic performance has been enhanced with new compensator spools, improving implement and travel multi-functioning, and better hydraulic flow sharing between functions.

521B/522B — ZeroTail SwingTrack Feller Buncher Features: ● Cat C9 ACERT Tier 3/Stage IIIA/Japan 2006 (Tier 3) equivalent high torque engine provides excellent power, fuel economy, serviceability and durability. ● A robust tilt mechanism , the tilting model (522B) has a patented 3-cylinder tilt mechanism with simulta- neous tilting forward and side-to-side. ● Proven rugged undercarriage designed for the tough- est harvesting conditions ranging from wet bottom- lands to steep rocky slopes. ● Hydraulically actuated clam-shell service door pro- vides full service and reduces maintenance down time. ● Comfortable, purpose built forestry cab with heavy duty guarding meets FOPS/ROPS/OPS and OR/OSHA requirements. ● Flexaire fan (standard) allows the cooling fan to purge debris from the radiator area minimizing cooling system maintenance. ● Felling heads utilize high pressure hydraulics and proven components to meet your application requirements. ● IQAN display allows the operator to continuously monitor the machine and get early warning for poten- tial problems. ● Ergonomically located pedals with side-by-side foot rests provide maximum operator comfort when the machine is traveling. ● Serviceability has been improved with vertical mounted main hydraulic control valves and increased hood enclosure area. A larger standard fuel tank allows more run time between re-fueling stops. ● Hydraulic performance has been enhanced with new compensator spools, improving implement and travel multi-functioning, and better hydraulic flow sharing between functions.
