Key Features

Steer Assist

Steer Assist automates track steering with light and heavy loads.
Automates blade tilt steering to help push heavy loads with less effort.
Helps reduce operator inputs by up to 75% by automatically maintaining straight travel with light loads on flat ground and side slopes.
Operators of various skill levels can use Steer Assist to push light and heavy loads more effectively.

Steer Assist 3D

Steer Assist 3D enables machines to automatically follow guidance lines from site design plans (or Infield designs) under light or heavy loads.
Helps to more accurately cut or spread material with precise steering to an edge, toe, crown, etc.
Reduces the number of passes with precise pass-to-pass overlap.
Increase heavy dozing productivity by using AutoCarry, Traction Control, Cat Grade with 3D, and Steer Assist 3D using blade tilt steering, especially for less experienced operators.

*Steer Assist 3D requires Grade with 3D to enable.

EASY TO USE

Steer Assist activation:
1. Use machine monitor to toggle on feature
2. Shift into forward or reverse
3. Steer to desired heading
4. Release steering command to maintain desired heading

Steer Assist 3D activation:
1. Use machine monitor to toggle on feature
2. Use grade monitor to load grade design and select guidance line
3. Shift into forward
4. Push left button on the right joystick to engage AUTO mode
5. Move blade tip to within capture range
6. Release steering command

Operators can take manual control of the machine steering or blade to temporarily override Steer Assist. When the operator is no longer giving a manual command, control is given back to Steer Assist.

MACHINE SETTINGS

Blade Steer is used to steer with blade tilt commands under heavy loads (on/off).
Reverse Guidance Mode is used to set reverse travel behavior in Steer Assist 3D (two choices):

– Straight Line keeps the machine traveling straight
– Grade Line enables machine to follow grade design guidance lines

Capture Range is used to adjust the distance from the guidance line to begin automatic steering in Steer Assist 3D (range is 0.1-10.0 m [3.9 in-32.8 ft]).
Auto/Manual Joystick Button is used to set how Grade Control and Steer Assist 3D are changed between AUTO state and MANUAL state (two choices):

– Linked for a short press to change both Grade Control and Steer Assist 3D state
– Unlinked for a short press to change Grade Control state and a long press to change Steer Assist 3D state
