Description

The Blue Diamond 12' Flex-Wing Rotary Cutter for Tractors is built for medium-duty mowing, field maintenance, pasture cleanup, and brush cutting with compact and utility tractors. With a 144-inch cutting width and smooth top deck design, this rotary cutter gives operators wide mowing coverage while staying practical for tractors with lower PTO horsepower requirements.

Designed for tractors with a minimum 35 PTO HP, this 12-foot flex-wing rotary cutter is made for cutting weeds, grass, and brush up to 2 inches in diameter. The cutter uses three independent spindles with two free-swinging blades each, helping reduce shock when working through rough conditions or contacting hidden obstacles.

With protected gearboxes and drivelines, slip clutch protection, single-spring suspension, debris discharge safety chains, four flat-free laminated tires, and single-circuit hydraulics requiring only one hose connection, the Blue Diamond 12' Flex-Wing Rotary Cutter is a strong option for farms, ranches, municipalities, landowners, and maintenance crews.

Frequently Asked Questions

Find answers to common questions about our products and services

Explore our wide selection of high-quality skid steer attachments designed for performance and durability. We partner with trusted manufacturers to provide reliable attachments for a variety of applications. Our knowledgeable team is here to help you find the right equipment for your machine and job requirements.

Most modern full-size skid steer attachments are built with a universal quick attach system, allowing them to connect with nearly any brand of skid steer loader on the market. This standard design makes it easy to switch between attachments from different manufacturers.

If your machine does not have a universal quick attach system, or if you are purchasing attachments for a tractor or another type of equipment, we can help. We offer quick attach adapters that allow your machine to safely connect to a wide range of attachments.

Most modern skid steer loaders are equipped with auxiliary hydraulics that power attachments requiring hydraulic flow. These hydraulic lines typically connect to the machine through couplers located near the loader arms.

The type and number of hydraulic couplers can vary depending on the machine. Attachments that require low hydraulic flow, such as standard brush cutters, typically use two half-inch couplers. Machines with high-flow capability may include additional couplers and a case drain line for more demanding attachments.

When purchasing a hydraulic attachment, it is important to ensure that the attachment’s hydraulic requirements match your skid steer’s operating range. For example, grapples and backhoe attachments usually require low flow, while larger brush cutters and forestry attachments often require high-flow hydraulics.

Some skid steer attachments use electrically actuated controls combined with hydraulic components. For example, certain grading blades use electrical switches in the cab to activate hydraulic valves that control features such as folding wings.

If an attachment requires electrical controls, it is easiest when your skid steer is equipped with an external electrical harness. Since electrical harness systems can vary by manufacturer, we recommend contacting our team to confirm compatibility before ordering.

If your skid steer does not have an external electrical harness, we can often provide a controller that connects to your machine’s 12-volt power source or battery. This allows you to operate attachments that require electrical controls safely and efficiently.

Safety should always be a top priority when operating skid steer loader attachments. At Heavy Equip Tech, we often hear from customers who accidentally damage the glass door on their skid loader when using attachments such as forestry mulchers, brush cutters, or post drivers. This usually happens when the potential impact of debris on the machine’s cab is not fully considered before purchasing the attachment.

When shopping for skid steer attachments, it is important to research the equipment thoroughly or consult with a customer support specialist to ensure proper compatibility and safe operation. Certain attachments that can throw rocks, wood debris, or other materials require additional safety precautions.
