Section 3: Operating Procedures

IMPORTANT: Your Rotary Cutter is equipped with free swinging cutting blades to reduce shock loads to the cutter when striking obstacles. The cutting blades can lock together while transporting. Always check for locked blades before starting to cut.

6.Set tractor throttle to idle or slightly above idle and slowly engage PTO. Start-up vibration is normal and should stop after a few revolutions of the blade carrier. Stop PTO rotation if vibration continues. Wait for PTO to come to a complete stop and then dismount from tractor to check for probable causes such as blades locked together.

7.Once cutter is running smoothly, increase tractor PTO speed to cutter rated PTO speed. Stop PTO rotation immediately if vibration occurs. Wait for the PTO to come to a complete stop and then dismount from the tractor to check for probable causes.

8.Optimum ground speed will depend on density of material being cut, terrain and operator skill. If in doubt, change gears to reduce tractor ground speed to a comfortable level.

Breakaway Operating Procedures

Refer to Figure 3-1:

The deck and parallel arms are designed to breakaway should the cutter head make contact with an immovable object or irregular terrain during forward travel. This “breakaway” feature will protect the cutter against structural damage by allowing the deck and parallel arms to pivot backwards.

Upon breakaway, the cutter head must be reset to original “home” position before normal cutting operations can resume.

IMPORTANT: Do not attempt to operate cutter in reverse. The breakaway mechanism will function correctly ONLY while tractor is moving forward. Cutting while backing up may cause structural damage to the parallel arms and deck if cutter head strikes a solid or immovable object.

1.Raise arms and deck up to clear any obstacles located behind the cutter deck.

2.Slowly back cutter away from any obstacles that will interfere with pivoting unit back to “home” position.

3.Use tractor’s remote (breakaway cylinder) control to pivot unit back to “home” position.

Cylinder Shear Bolt

Refer to Figure 3-1:

A shear bolt is located at the rod end of the breakaway cylinder. This bolt may shear under the following conditions:

•After breakaway, the operator backs the tractor away from the obstruction, but encounters an additional obstruction or immovable object while backing up.

Specifically, the operator did not raise the deck high enough to clear the object before backing up.

•The operator tried to reset the deck and parallel arms by backing the tractor into an obstruction rather than using the tractor’s remote cylinder control.

•The shear bolt has become fatigued after repeated breakaway and reset cycles.

•The shear bolt self-locking nut has been tightened against the clevis causing a pre-loaded stress on the bolt and the bolt to shear at a reduced breakaway force.

Shear Bolt Space

Figure 3-1

Replace shear bolt with correct replacement part (Land Pride Part No. 802-885C). A substitute shear bolt may result in damage to the parallel arms and/or main frame. A single replacement part is included with each cutter and is located on a bracket adjacent to the upper 3-point hitch.

IMPORTANT: Install self-locking nut onto shear bolt until nut is threaded to within approximately 1/32" of contact with clevis as shown in Figure 3-1.

Un-hooking the Rotary Cutter

The following steps should be done when un-hooking the cutter.

IMPORTANT: Make sure transport safety chain is attached to the Rotary Cutter deck and Float Switch, if available, is “OFF” before un-hooking the cutter.

1.Park on a level solid surface.

2.Lower cutter frame to level ground or onto blocks supporting the frame just above ground level.

3.Engage tractor park brake, shut tractor engine off and remove switch key before dismounting from tractor.

4.Unhook control stick from connector at the cutter and power source. Store control stick in a dry location.

5.Disconnect driveline from tractor PTO shaft.

6.Disconnect hoses from tractor duplex outlets.

7.Un-hook 3-point hitch from tractor. Reinstall hitch pins, linch pins and hair pin cotters in cutter hitch for storage.

8.See “Cutter Storage” on page 39 when cutter is not going to be used for a long time.

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.
