B79 Medium 79" (2.0m)

SharpGrade Box Blade Retracting Series

Our SharpGrade B79 Medium 79" (2.0m) series box blade shares the same sealed, shielded & lifetime lubricated QuadRod linkage as the Heavy Duty series. The mono beam chassis and close coupled wheels offer low ground pressure and exceptional visibility. Ideal for mid-frame skid steers in the 65 – 85 HP bracket: residential pads, medium industrial flat work, curb & gutter / sidewalk prep, equestrian surfaces.

  • Sealed, shielded and lifetime lubricated QuadRod linkage; Never requires greasing
  • Retracting front wheels: use as a dozer, buck piles, confined areas, while maintaining accuracy
  • No centre pivot; 3 times faster to grade than conventional designs, no duck walking
  • Adjustable Hitch plate: sets chassis level on lower stops for precision grading
  • Mono-beam chassis with close coupled wheels: low ground pressure with enhanced visibility

Product Details

Transform your skidsteer loader into a precision box grader

Get the performance of a larger grading machine right from the seat of your skidsteer loader and take advantage of your loader's inherent manoeuvrability to level ground with unparalleled ease and efficiency.

Benefits:

Using a SharpGrade Box Blade is up to ten times faster than levelling using a skidsteer with standard bucket attachment.

Optional Total Station or dual GNSS 3D systems allows you to easily grade complex contours with several gradients, diverging offset crown and different cambers directly from the control of the SharpGrade.

Accurate grading made easy

The SharpGrade Box Blade enables you to accurately level, to within 1/8" (3mm), large areas or small tight spaces with ease and efficiency. Features such as knife edge side shields and retracting wheel allow you to accurately trim right up to edges and get into tight corners. Large mirrors let you see exactly what's happening on the whole front blade, eliminating blind spots.

Fast results

Designed specifically to work on skidsteer loaders the SharpGrade Box Blade works in forward and reverse for optimal efficiency. Twin pivoting blades give the ability to cut, carry, trim, spread and finish in one pass, in either direction, for speed and control. A curved mouldboard ensures wet material can be easily rolled. Operated from your machine's hydraulic system, in-cab adjustments are a breeze and levelling is up to ten times faster than levelling using a skidsteer and standard bucket attachment.

Plug and play attachment

The SharpGrade Box Blade is quick and easy to attach to your machine. No tools required, simply clip the unit into place and attach the hoses and you're ready to start work.

Maintenance free performance

Designed and built with longevity in mind, the SharpGrade box blade features induction hardened pins, self-lubricated bushes and dirt seals in all moving joints, so it won’t let you down when time equals money. Our patented, sealed QuadRod system keeps the blade rigid and accurate at all times, with low maintenance. Simple hydraulic valves with built in relief protects the system from overload. Valves feature manual override capability to allow easy diagnosis if there is ever a problem.

Standard Features:

  • Optional QuadGrade 2D system with adjustable grade height receivers: We offer our bespoke QuadGrade 2D machine control system or can supply our attachment bare but ready for Topcon or Leica 2D or 3D. Electronically adjust the grade height 1/25" (1mm) at a time without leaving your seat. Increased receiver range means you stay on grade longer. It is highly accurate and easy to use, the blade can be manually operated by the 4 in 1 control at any time, with or without the laser control connected. Compatible with skid steers, small wheel loaders and mini excavators
  • Greased for life, low maintenance design. Induction hardened pins, permanently sealed, self-lubricated bushes and dirt seals in all moving joints provide a long low maintenance life.
  • Unique QuadRod Linkage. The Patented QuadRod system gives unparalleled rigidity, allowing use on 100+ HP machines. With only 4 arms, the outboard cylinders are directly connected to the outer edges of the blade, achieving the ultimate in accuracy. All joints are lifetime sealed, lubricated and maintenance free, with no greasing required.
  • Retracting wheels: Offer the ultimate in compact grading, get up close to walls, curbs, foundations or use as a bulldozer, while providing the shortest transport length in class.
  • Adjustable hitch plate: Sets SharpGrade perfectly level with boom fully down to provide the ultimate in rigidity. This reduces track and tire wear and boom and linkage wear as the SharpGrade is pushing on the front of the machine instead of transferring the load to the rear of the machine through the linkages. This is especially important with vertical lift machines.
  • Twin parabolic mirrors: See the front blade and both front wing tips for confident grading in confined areas, along walls, curbs or foundations.
  • Graduated laminated, galvanizes laser poles: Quick, easy set up of laser receivers with our built in measuring tapes on our laser poles. Available in metric and imperial dimensioning, no tape measure required. Lamination reduces vibration of the receivers.
