2026 AMCO AD-540-V

Vertical & Offset Rotary Ditchers

From coupler to cutter head, AMCO makes a better drainage ditcher. Clean roadside ditches or direct water away from crops with the AMCO Rotary Ditcher, an industry best-seller. We offer both offset and vertical models, including the Dominator™ Vertical Rotary Ditcher for tractors with higher horsepower. Ditcher options are available for tractors with PTO ratings of 540 and 1,000.

• Our cutter heads feature five heat-treated, replaceable blades. The cutter head width is adjustable from 18″ to 20″ or from 24″ to 26″.
• The original vertical and offset body styles can be ordered with either diameter cutter head. The Dominator can be ordered with a 24″ to 26″ diameter cutter head.
• Securing the PTO drive shaft for storage is easy with a parking hook on the side of the unit. Our ditchers come with Series 55 PTO drivelines with shear bolt protection.
• Standard on all models is a concave skid shoe design with quick-adjust ratchet, which allows the drainage ditcher to track better and form a more uniform ditch. The skid shoe mount is located behind the gear case and helps prevent debris buildup around the cutter head.
• The ripper shank loosens tough soils and prolongs bearing life. The bearings have a two-year warranty.
• AMCO ditchers come with a case-hardened dual #80 heavy-duty chain with 16-tooth and 22-tooth drive sprockets.
• The powder-coated finish is more durable and environmentally friendly.

Features May Include: 

The heavy-duty AMCO Dominator Vertical Rotary Ditcher is a perfect fit for tractors in the 80–200 horsepower range. The Dominator weighs 850 lbs. and features a cutter head that’s adjustable from 24″ to 26″. Because of the size of the cutter head, the Dominator can dig a wide, shallow ditch that is easy for tractors and sprayers to cross. Like the original Vertical Rotary Ditcher, the Dominator’s cutter head has a traditional center placement, straddling the ditch during cleanout.
