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.

- Each chain drive is equipped with an adjustable idler sprocket with case-hardened teeth
- An all-welded main frame has chain-case construction of 6″ x 10″ x ¼″ tubing

The AMCO Offset Rotary Ditcher offers outstanding performance in wet conditions and gives farmers the ability to dig drainage ditches for improved water drainage in any crop or soil type. The offset is designed so the cutter head sits behind the left tractor tire, leaving only the right tire track alongside the ditch. To clean out ditches, drop one tire into the ditch. The offset is also better for cleaning out ditches than conventional drainage ditchers; no need to straddle the ditch, just drop a tire in it and go.
- Robust frame
- Easy functionality
- Heavy-duty, endless double #80 roller chain that runs continuously in a sealed oil bath
- Concave skid shoe; the skid shoe mount is located behind the ditcher gear case to keep debris and mud from building up around the cutter head
- Standard buster shank
- Available in 540 and 1,000 PTO
