Speed and Power

The Speed and Power tab displays the values listed below. Dashes indicate the value is not available.

 

GPS Speed

GPS speed is the ground speed of the machine calculated by GPS, if available. Accuracy of GPS speed can be influenced by several factors. For example, trees or power lines can block communication between the GPS receiver and satellites. Additionally, satellite signal reflected off of surfaces, such as metal sheeting of buildings, can cause problems. If a GPS Receiver is not installed on the machine or if GPS speed is not available, dashes will be shown.

Slow Speeds

Depending on machine settings, GPS speed will display an additional decimal place or switch to a different unit (km/h to m/h or mph to ft/h) when the tractor is moving slower than 0.5 km/h (0.3 mph).

GPS speed will switch back to default readings (km/h or mph with one decimal place) when the tractor exceeds 1.6 km/h (1.0 mph).

 

Wheel Slip

Wheel slip is the difference between current wheel speed and current GPS or Radar speed, shown as a percentage. If either GPS or Radar speed is not available, or the machine is moving slower than 0.1 km/h (0.06 mph), dashes will be shown. If wheel speed is equal to GPS/Radar speed, wheel slip is 0 percent.

Note: The most effective wheel slip for most draft operations is between 10 and 15 percent.

 

Wheel Speed

Wheel speed is the current ground speed of the machine measured by wheel rotations. If the machine has high slip, the actual speed will be slower than the value shown. If the wheel speed is significantly too high or low, see tractor's operator's manual for more details.

Slow Speeds

Depending on machine settings, GPS speed will display an additional decimal place or switch to a different unit (km/h to m/h or mph to ft/h) when the tractor moves slower than 0.5 km/h (0.3 mph).

GPS speed will switch back to default readings (km/h or mph with one decimal place) when the tractor exceeds 1.6 km/h (1.0 mph).

 

Radar Speed

Radar speed is the ground speed of the machine measured by an attached radar device, if installed. Radar Speed accuracy is negatively influenced by dust, high crops, and windy conditions. If Radar Speed is significantly too high or low, calibrate the radar. See Maintenance and Calibrations help for more information. If radar is not installed on the machine, dashes will be shown.

Slow Speeds

Depending on machine settings, GPS speed will display an additional decimal place or switch to a different unit (km/h to m/h or mph to ft/h) when the tractor is moving slower than 0.5 km/h (0.3 mph).

GPS speed will switch back to default readings (km/h or mph with one decimal place) when the tractor exceeds 1.6 km/h (1.0 mph).

 

Engine Speed

Engine Speed is the current number of revolutions per minute (RPM) of the machine engine.

 

Engine Load

Engine load is the current power taken off the engine displayed as a percentage. For example, if a 200 horsepower engine is currently delivering only 100 horsepower, engine load is 50 percent.

 

Rear PTO Speed

Rear PTO speed is the number of revolutions per minute (RPM) of the rear PTO.

 

Front PTO Speed

Front PTO speed is the number of revolutions per minute (RPM) of the front PTO.
