Description

Automatic Grade Control Sonic Slope | Bobcat

Bobcat® Automatic Grade Control Systems improve grading accuracy and efficiency while reducing the time and labor required to achieve a precise finish. By automatically maintaining blade position, these systems allow operators to focus on machine operation with less fatigue and fewer manual adjustments. With accuracy better than ±¼ inch, automatic grade control reduces the need for continuous grade checking, minimizes rework, and helps prevent costly material overuse on projects requiring precise finishes, including concrete preparation.

Automatic Grade Control Sonic Slope Key Features

What Makes the Automatic Grade Control Sonic Slope Different

Automatic sonic elevation and cross-slope control for accurate finish grading around obstacles or along an existing reference.

More Accurate Grading

Bobcat automatic grading solutions deliver more accurate grading results with less time and labor.

Greater Efficiency, Less Fatigue

Increase efficiency and reduce fatigue without having to focus continuously on blade position.

Fewer Manual Grade Checks

Near-perfect accuracy reduces the need for a crew to continually check grade.

Better Than ± 1/4-Inch Accuracy

Accuracy better than ± 1/4 inch can reduce waste on expensive finish materials such as concrete.

Automatic Grade Control Sonic Slope Features & Benefits

Features & Benefits 3
Automatic Control

Less operator input is required while providing better accuracy, reduced operator fatigue and faster travel speeds.

Fingertip Controls

Mounted on the carrier's steering levers, fingertip controls provide quick access to make elevation changes or switch the automatic function on or off, delivering precise results with maximum operator comfort.

Manual Override Function

Moving the blade up or down while in automatic mode momentarily interrupts automatic control. When the operator releases the switch, the system immediately returns to automatic mode.

Why Buyers Choose It

Accurate Grade Without a Laser Reference

Better than ± 1/4-inch accuracy helps reduce rework and finish-material costs

Sonic tracing follows curbs, stringlines or previous passes around jobsite obstacles

Automatic elevation and cross-slope control reduces operator input and fatigue

Manual override and fingertip controls keep adjustments fast and intuitive

Top Tasks & Operation

How Sonic/Slope Grade Control Works

Top Tasks

  • Accurate finish grading
  • Efficient rough grading
  • Golf-cart paths, bike trails and similar path construction
  • Concrete flatwork

Three Main Components

  • The sonic tracer controls elevation on its side of the moldboard.
  • The cross-slope sensor maintains a set cross-slope on the opposite side.
  • The deluxe instrumentation panel operates the system and displays distance-to-target information.
  • Rotation and mainfall sensors correct slope information on hills or with the blade angled.

Setting Grade

  • The operator positions the sonic tracer above a reference such as a stringline, previous pass or curb, sets the blade depth and zeros the tracer from the deluxe instrumentation panel.
  • For road subgrade beside a completed curb and gutter, the cutting edge can be set 6 inches below the curb while a 1% cross-slope is entered for the road crown. In automatic mode, the blade maintains both settings as the loader travels.
  • The sonic tracer can also be disabled so the operator manually controls one side of the blade while the cross-slope sensor automatically controls the other. This is useful for smoothing a first pass that the tracer can follow on the next pass.

Sonic Tracer

  • Mounts on either side of the moldboard.
  • Uses ultrasonic signals to maintain distance from the reference below.
  • Moves only the elevation cylinder on its side of the blade.

Cross-Slope Sensor

  • Moves the opposite side of the blade from the sonic tracer.
  • Maintains the cross-slope entered by the operator.
  • Controls only the elevation cylinder on its side.

Deluxe Instrumentation

  • Sets the grading-system parameters.
  • Shows real-time distance to target for elevation and slope.
  • Conserves valuable cab space.
