Cat® SMART Grader Blade attachments are for cutting, moving and grading dirt, gravel, sand and virtually any other material used as a base. There is an assist feature of the blade that takes the unit beyond SMART. The SMART grader blade brings cross slope to SSL/CTL platforms.

Attachment Control Mode (manual) turns the D3 and SMART Grader into a machine that is controlled more intuitively for the job at hand. The left joystick maintains control of the machine drive functions. The right joysticks now operate the attachment.

The dedicated screen of the SMART Dozer provides the operator with feedback on the orientation of the attachment. The operator will see attachment blade slope as well as angle of the blade.

With cross slope enabled, the operator selects the desired cross slope of the blade by placing the blade to the desired position. Then the attachment maintains that desired slope during operation, even when the machine slope changes.

Grader Blade attachment is external reference ready. Cat Grade (GPS and UTS), EW GO!, Total Station.

Curved moldboard allows for material to roll and fold, improving capacity and performance. Flowing material will easily find low spots and improve grading and leveling performance.

Wear indicating cutting edges feature 20% more wear material on the ground engaging section of the edge and also indicate when it is time to flip (center section only) or replace the edge.

Dual parabolic mirrors provide full visibility to the front cutting edge allowing the operator to see how much the blade is loading and see out to the corners of the blade.

Technology components are centrally located and simply route to their respective harnesses back to this location on the tool. Then, a single harness routes to the control module in the cab or on the tool.

The hydraulic valve and ECM (Electronic Control Module) are enclosed and mounted within the frame of the tool, protected from damage.

Dual front wheels are mounted on an independent axle and on casters to provide stability in both directions of travel. These wheels are air filled and will provide balance for the blade in both automatic and manual operation.

Optional side wings allow the operator to make the blade wider and carry material similar to box blades.

Standard fixed masts provide great performance for single or dual laser technology configurations as well as supporting 3D technology. Bolt pattern fits Accugrade™ Std. GNSS masts.

Serrated bolt-on step provides safe ingress and egress from machine cab. Additional weld-on serrated steps on the blade ensure safe receiver adjustment, install, or removal.

Tool mounted and sealed from the elements, this holder includes all of the operation manuals and maintenance guides required for proper operation of the work tool.+E2:E16
