Hydraulic Flow Control Settings

The hydraulic cylinders require 5 GPM (gallons per minute) to function properly. This is set by adjusting the flow control valve(s) and then timing how long it takes for the cylinder to fully retract. The valve is adjusted correctly when it takes 5 seconds to retract.

Cutter Flow Control

Refer to Figure 2-1:

IMPORTANT: Oil overheating may occur if flow control is not achieved. Damage to o-rings in the solenoid valve and/or in the cylinders may occur if oil becomes overheated.

An auxiliary flow control valve is included with the cutter when provided with solenoid controlled cylinders. The flow control valve diverts excess oil back to the tractor keeping oil cooler and back pressure down.

Plumbing shown is for tractors with hydraulic oil flow rate of 15 GPM and under.

Flow Control Valve for Solenoid Operated Cylinders

Figure 2-1

Refer to Figure 2-2:

1.Set Rotary Cutter in folded transport position. (All parallel arm and deck cylinders are fully retracted when in transport position.)

2.Press and hold “ARM 2 OUT” push button switch to fully raise outboard arm up. Release switch when cylinder is fully extended.

3.Press and hold “ARM 2 IN” push button switch and time how long it takes to cycle from fully extended to fully retracted.

4.Adjust flow control knob (See Figure 2-1) until cycle time is 5 seconds.

Tractor Flow Control

Refer to Figure 2-2:

NOTE: Parallel Arm Cutters with (S/N 163695-) will require flow control valve kit #316-068K if your tractor does not have flow control (turtle/rabbit control) or if your tractor uses an open center hydraulic system. Check your tractor’s operator’s manual to determine your tractor’s set-up.

The tractor’s turtle/rabbit flow control valves are used when all hydraulic connections are connected directly to the tractor outlets.

1.Set cutter in folded transport position. (All parallel arm and deck cylinders are fully retracted when in transport position.)

2.Operate tractor “ARM 2” lever to raise outboard arm fully up as shown.

3.Operate tractor “ARM 2” lever to fully retract outboard arm and time how long it takes to cycle from fully extended to fully retracted.

4.Adjust turtle/rabbit control until cycle time is 5 seconds.

5.Repeat steps 2 and 3 for “ARM 1” and “DECK” cylinders.

If the cutter is having hydraulic overheating problems and the turtle/rabbit flow control valves have been set correctly, then check tractor operator’s manual for power beyond hook-up.

RCP2660, RCPM2660, RCPM3060, RCP3060 specifications

Land Pride has a longstanding reputation for producing high-quality agricultural equipment, and their line of RCP series rotary cutters, including the RCP3060, RCPM3060, RCPM2660, and RCP2660, exemplifies this commitment. Designed for professional landscapers and farmers alike, these rotary cutters are engineered for durability, efficiency, and performance in managing heavy brush and grass.

The RCP3060 is the largest in the series, boasting a 60-inch cutting width. It is equipped with a robust frame and is compatible with a range of tractors, making it an ideal choice for large-scale property maintenance and land management. The cutter employs a heavy-duty, reinforced cutting deck, which ensures longevity and able to withstand tough conditions. It utilizes a superior blade design that delivers clean and consistent cuts, promoting healthier growth of remaining grass and vegetation.

The RCPM3060, a medium-duty model, also features a 60-inch cutting width but is designed for lighter applications compared to the RCP3060. It incorporates similar build quality but is lighter, making it suitable for smaller tractors while still handling brush and grass efficiently. The integrated slip clutch protects the drive line from damage in case of blade contact with a solid object.

Both RCPM2660 and RCP2660 models provide a more compact solution with a 66-inch cutting width. The RCPM2660 is specifically tailored for medium-duty tasks, while the RCP2660 serves heavy-duty needs. Both cutters promote high productivity and versatility, making them suitable not just for agricultural use but also for commercial landscaping applications. The blades are designed for easy replacement, ensuring minimal downtime during operation.

All models in the RCP series integrate advanced technologies such as a quick-attach feature for easy connectivity, and adjustable side skids to control cutting height effectively. The heavy-gauge steel construction provides enhanced durability and helps reduce vibrations during operation. Furthermore, Land Pride's commitment to safety is reflected in the design with features that minimize dust and debris exposure.

In conclusion, whether you choose the RCP3060, RCPM3060, RCPM2660, or RCP2660, you can rely on Land Pride's RCP series rotary cutters to deliver outstanding performance and reliability, designed to withstand the demands of any landscape maintenance task.
