Steering made easy
John Deere has introduced
ActiveCommand Steering (ACS™), a new steering technology that makes
the tractor easier to drive by adjusting the amount of effort required to turn
the steering wheel and the number of steering wheel turns. It also helps prevent
oversteering and provides improved line-holding ability. Deere officials say operators will
drive with more confidence, comfort, and control.
Optional on 2011 8R Series
wheel model tractors only, a dynamic road-wheel offset control uses a gyroscope
to sense the tractor’s movement and automatically makes small adjustments. For
example, "a pothole steers the tractor to the right or left," says
Chad Hogan, marketing manager for the 8 family of tractors. "With ACS, the
gyroscope recognizes the pothole and corrects the steering automatically."
Operators will keep the tractor straight in their lane with minimal effort --
even at transport speeds of 31 mph (50 km/h).
changes the amount of effort required to turn the wheel based on conditions. Operators make fewer turns of the
wheel during headland turns for enhanced comfort, and slightly more turns of
the wheel during transport for improved control. Variable-effort steering
changes the resistance of the steering wheel in respect to ground speed for
light steering effort at slower speeds and higher steering-wheel torque during
transport speeds. "Traditional steering systems provide some steering
slop," Hogan says. "With electronic ActiveCommand Steering, we
completely eliminate slop." The system eliminates drift, as well, "so
on the steering wheel, 12:00 is always 12:00."
Additionally, John Deere was
awarded a 2009 gold medal for their ACS technology at Agritechnica, a leading
agricultural equipment trade fair held in Hannover, Germany.
Steer Your Deere
As part of the unveiling of
ACS, John Deere has partnered with Agriculture.com to develop "Steer Your
Deere," a Web-based game allowing users to navigate a John Deere 8R Series
tractor down an obstacle-strewn path. Along the way, you'll have the chance to
acquire ACS, immediately noticing easier steering ability. You'll generate
income for travel time, overtime and bonus items, but you stand to lose some
for uncontrolled driving. Rocks, hay bales, and logs abound.
