ADDITIONAL TRANSMISSION CONTROLS
CVXDRIVE
™
AUTOMATIC AND MANUAL MODES
The transmission is an electronically controlled continuously variable speed transmission. The transmission does not operate in
xed ratios, but allows the operator to combine the desired engine speed with the desired transmission ratio:
• to maximize the power available for the current application,
• or to operate in the most economical fashion.
The transmission always operates in one of two modes: automatic or manual. In automatic mode, engine speed is
automatically controlled, and the transmission selects the appropriate ratios to achieve the target speed for the given load.
In manual mode, reaching the target speed depends on the engine speed selected. The maximum speed for three speed
ranges, for example, 16 km/h (10 mph), 32 km/h (20 mph) or 50 km/h (30 mph), can only be achieved at the rated engine
speed of the tractor – 2000 RPM.
The instrument cluster and the display show the current mode.
For most applications, the operator should choose the default
automatic mode to allow the transmission to deliver the required
power for the application while maintaining the desired ground speed.
Throughout this discussion of the hand and foot controls,
operating and driving the tractor with a CVXDrive
™
transmission,
pay attention to the differences between automatic and manual
mode to choose the best tools for the application at hand.
On a CVXDrive tractor the operator can see the RPM
settings of the double throttles. As the throttles are
moved the RPM level will reect the RPM change.
The screen will also show if the manual mode is
turned on and if CPRM (constant engine RPM speed)
is turned on.
1 the engine speed setting for the left-hand throttle – 900 RPM in this example,
2 the current speed setting for the right-hand throttle – 2200 RPM in this example,
3 the working speed range,
4 the current mode of operation – Automatic or Manual,
5 and constant engine RPM speed status.
The transmission screen reports the relative position
of the throttles to one another as well as:
