Your Compact Track Loader Can Grade: A Buyer’s Guide to Grade Control Attachments and Systems

Compact track loaders are changing how contractors approach grading. Once limited to bigger machines and bulk earthmoving, grade control technology is now fully at home on CTLs — bringing unprecedented precision, speed and efficiency to compact jobsites. This Grade Control Buyer’s Guide is your entry point to the best attachments and systems designed to automate grading work with CTLs. Before diving into the product listings, let’s break down the basics: how grade control works, the differences between 2D and 3D and what to consider when investing in this technology.

What Is Grade Control?

Grade control systems automate the positioning and movement of grading attachments. Instead of relying solely on operator skill and string lines, a CTL equipped with a grade control system uses sensors, lasers, GPS or total stations to maintain the correct elevation and slope. The result? Faster passes, tighter tolerances and fewer callbacks. Whether you’re building pads, parking lots, sidewalks or sports fields, grade control turns your CTL into a finishing machine.

Why CTLs for Grading?

Compact track loaders dominate the compact equipment market — and for good reason. Their rubber tracks reduce surface damage. Their maneuverability shines in tight spaces. Their hydraulic capabilities power serious grading tools. Tracks produce more stability and pushing power. Add grade control, and CTLs rival small dozers and motor graders for fine grading tasks. With the right setup, they’re more than up to the challenge.

2D vs. 3D: What’s the Difference?

There are two main types of grade control systems: 2D and 3D.

2D Grade Control

These systems use laser receivers, slope sensors or sonic tracers. They’re ideal for basic flatwork, single-slope grading and simple site prep.

• Best for: Flat pads, driveways, parking lots
• Lower cost and easier to install
• Requires laser transmitter or reference line

3D Grade Control

3D systems integrate GPS/GNSS or total station data with the CTL’s blade or grading attachment. They automatically adjust for complex contours and multi-slope designs.

• Best for: Complex grading, sitework and engineered plans
• Requires base stations, antennas and software
• Provides full jobsite coverage and repeatability

Tips Before You Buy

1. Know your jobsite.
Flat residential pads? 2D may be enough. Complex commercial sitework? Go 3D.

2. Think long-term.
Look for systems that scale. Many 2D platforms can upgrade to 3D later.

3. Match your machine.
Ensure your CTL supports the hydraulics, mounts and power needs of the system.

4. Invest in training.
Even the best systems need skilled setup and operation. Training pays off quickly.

5. Consider your workflow.
Will your control system integrate with other machines or survey data?
