Commander III Trimmer

High-Production with the Commander III Trimmer

GOMACO Commander III trimmer

• High-production trimmer capable of widths up to 11 feet (3.4 m)

• Features the same framework as the Commander III curb and gutter model, but with minor modifications

- Right, front track has been switched to a pivoting front track to accommodate zero trimmerhead clearance on both sides

- Front tracks are parallel and trimmerhead is undermounted

- Vibrator hydraulics for paving applications removed and replaced with a bigger, closed-loop trimmer pump for more power

• Equipped with the most powerful trimmer ever put on a Commander III

- 114 horsepower (85 kW) of the total engine power dedicated to the trimmer

• Capable of trimming flat or monolithic sidewalk and curb and gutter profiles

• Trimmerhead has three air shocks to keep it stable during the trimming process

- If it would hit a large rock or other object, the air shocks reduce some of the force of impact into the Commander III’s mainframe

• Two conveyors move the material

- Transfer conveyor moves material from the trimmerhead on the front of the machine towards the discharging conveyor in back

- Each belt is 11 feet (3.4 m) long and 20 inches (508 mm) wide

- Discharge conveyor has seven feet (2.1 m) of sliding capabilities to place material over the stringline or discharge into the center of the roadway

• Shipping width is only 11 feet (3.4 m) and the Commander III trimmer transports as a single unit

• Trimming conversion can be retrofitted to higher horsepower existing new generation Commander IIIs with G21 or newer GOMACO control systems


The three-track Commander III high-production trimmer features a powerful trimmer to cut through the clay-based and rocky soil found in Calgary, Alberta, Canada, for monolithic sidewalk profiles.

  The Commander III trimmer has the ability to discharge the trimmed material to either side of the machine, either into the center of the roadway or over the stringline.

Doubling Our Per Day Production

This new (Commander III) trimmer has tons of power. We’ll trim for monolithic profiles that are two meters (6.6 ft) wide with a 550 millimeter (21.7 in) curb added on and it never slows down. The air-ride system that’s on the trimmerhead absorbs the shock of it all, so it doesn’t bounce around and we have a nice trimmed profile with the monolithic berm intact.

With our old method of trimming, we were trying to achieve 500 lineal meters (1640 ft) per day, per machine. With the new Commander III trimmer that we have now, we’re doing about 800 to 1000 lineal meters (2625 to 3281 ft), doubling our old per day production.
