The GT-3600 is now available with the optional G22, GOMACO’s new exclusive operating system. The exclusive G22 combines intelligence with simplicity. The G22’s new graphical display provides the operator with an easy to understand interface to the machine’s controls. Newly designed icons and screens with pictograms reduce the operator’s learning curve to a minimum. The brightly colored graphics and full text explanations provide the ultimate user-friendly operator experience.

The G22 has a dual-language feature with the ability to operate in English or a second language. It also offers the choice of metric or imperial measurements. The GOMACO control systems team has developed the G22 screens for the major languages of the world.

Advanced system diagnostics on the G22 automatically pinpoint and identify electrical circuit opens, shorts and fault codes to aide in troubleshooting. Faults are identified and a full explanation of recommended actions are given. That means less downtime and a quicker uptime on service because the G22 actually helps eliminate costly service time searching for system problems.

Leg size on the new generation GT-3600 was increased by 15 percent and features the same quality and durability as the GOMACO Commander III legs. An option for the standard trimmerhead is a radial piston hydraulic motor that makes this trimmer one of the most powerful on the market today. The motor provides an increase in torque for more power and a faster tooth-tip rotational speed which moves the material out of the trimmerhead at a higher rate. The new lightweight, molded fiberglass shroud allows easy removal or access to the engine components.

The control system also has a selective steering dial for five different modes of controlling the three tracks. This provides a choice for negotiating job-site conditions and loading for transport. The Crab Steering selection gives a quick approach and coordination to the stringline. The GT-3600 can easily reverse steer on-line to within 0.125 inch (3 mm) tolerance for a quick start. High-production performance through radii is accomplished with the control system’s tight radius software and the ability to toggle steering control from the lead sensor, eliminating continued manual sensor adjustments.

Control circuits on the GT-3600 are electronic-over-hydraulic for easy, accurate adjustments and an instant, controlled response. Smart hydraulic steering cylinders, interfaced with the G22, allow push-button steering setup. The programmable cylinders also allow steering parameters of the tracks to be set with the touch of a button. Optional auto-transition and slope compensation software is available to automatically transition in and out of “catch” or “spill” gutter. It automatically compensates for mold position in relationship to the stringline as a result of slope change.
