Product Details
Transform your skid steer or compact track loader into a precision grader blade
SharpGrade sets the benchmark with grader blade attachments for skid steers and compact track loaders. Built for precision and durability, each grader attachment incorporates innovations like QuadRod linkage and hydraulic wings, helping contractors in construction, landscaping, and paving achieve faster, more accurate results.
Bring big-grader capability to tight job sites with the SharpGrade G73. Designed for walk-behind or cab-equipped compact track loaders, it delivers rapid, precise grading from every angle, forward or reverse. This double-direction efficiency means you can move more material, finish surfaces faster, and keep your crew productive all day.
The G73 includes patented QuadRod linkages that are sealed, shielded, and permanently lubricated for a maintenance-free lifespan. An adjustable hitch plate and retractable front chassis make it adaptable to a variety of applications. Best suited for small-frame machines between 30–50 HP, it’s ideal for landscaping projects, residential pads, curb preparation, and arena grooming.
- Sealed, shielded and lifetime lubricated bearings throughout: Never requires greasing
- Patented QuadRod 3 linkage: keeps blade parallel throughout movement to maintain equal height between front & rear blade
- 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
- Outboard mounted cylinders reduce cross coupling to a minimum
- Robust, narrow boxed chassis for unsurpassed visibility
- Angle cylinders are mounted above the material, for longevity
Benefits:
Accurate grading made easy
The SharpGrade Skid Steer Grader Blade enables you to accurately level to within 1/8" (3mm). Using a SharpGrade Grader Blade is up to ten times faster than levelling using a skid steer with standard bucket attachment.
The optional QuadGrade 2D Laser Control system integrates with any 3D machine control system, allowing you to easily grade complex contours with several gradients, diverging offset crown and different cambers directly from the control of the SharpGrade.
Innovative Spring Plate Mount
Our proprietary Spring Plate design connects the linkages to the grader blade chassis like a shock absorber, effectively dissipating shocks from solid objects and protecting the structure. This feature not only enhances durability but also reduces weight, enabling operation on smaller base machines without sacrificing strength or performance.
Enhanced Energy Efficiency
Incorporating electronic load sensing and reduced weight construction, the G73 minimizes heat and energy loss. This results in superior performance from lower horsepower machines, significantly reducing fuel consumption and emissions, an essential benefit in today's environmentally conscious market.
Fast results
Designed specifically to work on skid steer and compact track loaders, the SharpGrade Grader Blade is the first in the world to work 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.
Robust, reversible hydraulic side wings give you the ability to carry material forwards or backwards when you need it.
A curved moldboard ensures wet material can be easily rolled. Operated from your machine's hydraulic system, in-cab adjustments are a breeze and leveling is up to ten times faster than leveling using a skid steer and standard bucket attachment.
Plug and play attachment
The SharpGrade Skid Steer Grader Blade is quick and easy to attach to your machine. No tools required, simply clip the unit into place and attach the hoses and the optional QuadGrade 2D machine control system comes pre-tuned, ready to start work.
Compact Machine Control Ready
The G73 is fully compatible with all major 2D and 3D compact machine control systems including QuadGrade, Trimble, and Topcon allowing you to upgrade your precision and productivity effortlessly.
Maintenance free performance
Designed and built with longevity in mind, the SharpGrade Skid Steer Grader 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. The patented, sealed QuadRod system keeps the blade rigid and accurate at all times, with low maintenance. High performance, proportional hydraulic valve, configurable to open & closed center, 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:
- Greased for life, low maintenance design. Induction hardened pins, permanently sealed, self-lubricated HardiLube bushes and dirt seals in all moving joints provide a long low maintenance life.
- Unique QuadRod Linkage. The Patented QuadRod 3 system gives unparalleled rigidity, rated to 50 HP machines (4,000kg per link). Utilizing 3 x Heavy Duty link 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.
- 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. Adjustable hitch plate keeps chassis perpendicular with the ground, so side wings stay flat throughout their travel. Rear viewing ports allow operator to see the rear blade.
- Twin large parabolic mirrors: See the front blade and both front wing tips for confident grading in confined areas, along walls, curbs or foundations.
- Twin blades: Front blade is fixed and reversible. Rear blade is pivoting and reversible. Pivoting blade reduces packing between the blades.
- Tires: 18.5"x 8.5"with labyrinth seals on wheel bearings keeping grit out.

- QuadGrade 2D machine control system: with adjustable grade height receivers: 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 all large frame skid steers.
- Removable laser poles: quickly change from long to short poles for indoor work or working in height restricted areas. No tools required.
- Direct Connect: Connect the SharpGrade Grader Blade to the base machine via the 14 pin plug on the boom, the operator can directly control the SharpGrade from the extra buttons on the handles. We have Direct Connect kits available for most brands, including ASV, Bobcat, Case, Cat, Deere, Kubota, Takeuchi & Wacker Neuson.
- Aligned QuadGrade Sonic system: Patented Aligned Sonic maintains cross fall when the blade is articulated. Reads a string line, curb lip, or grade match to a smooth surface for grades not possible to achieve with a laser. Plugs directly in and reads off the control panel. Height and slope adjustable from cab.
- Other Compact Machine Control Systems: Compatible with all leading 3D machine control systems.
