ROPS/FOPS cab, with rounded design and greater glazed area, allowing for more visibility on all directions.

F-Motoniveladoras-Hotspot-2

Central blade with multiradius, involute, curved profile, which allows effortless cutting.

F-Motoniveladoras-Hotspot-3

With the towing bar and the chassis circle, you have much more stability, and the maximum blade turning yield.

FEATURES

Resources

Open Close

CAB

  • Greater vision area.
  • Comfort and ergonomics at the inside environment.

INVOLUTE BLADE

  • Multiple radii.
  • Easy material rolling, thus increasing the earth moved volume.
  • Less stress on the blade, and more fuel savings.

TRANSMISSION

  • 6 speeds forward, and 3 reverse.
  • It is coupled to the engine via torque converter.
  • The converter features a locking system (Lock-up), which transforms it in a rigid coupling, starting to work as a Direct Drive system.
  • The operator can use either the automatic or manual modes.

LOAD SENSING TYPE HYDRAULIC SYSTEM

  • The hydraulic pump works in standby, consuming the minimum possible engine power, and when the application demands more flow, it is piloted for supplying the hydraulic system with the required flow, either higher or lower, depending on the operation.

SELF-ADJUSTING BRAKES

  • Oil bath, multidisc, self-adjusting brakes with two circuits, one for each side of the rear axle.

MAINTENANCE

  • Quick and at low cost.
  • Tilting hood, which improves access to engine components and to daily maintenance points.
  • Lubricating points accessible from ground level.

TOWING BAR AND CHASSIS CIRCLE

  • They provide stability, power, and maximum blade turning yield.

CONTROL LEVERS

  • Within operator’s reach and easy to operate.

RIPPER

  • 5-toothed rear ripper.

SCARIFIER

  • Front scarifier can have up to 11 teeth.

PLASTIC FUEL TANK

  • At ground level, with lock on the lid.
