The C451R pickup features premium components such as:
By using the HC Premium rotor – a feature available on John Deere round balers since 2012 – the C451R feeding system offers:
This smooth crop flow enables high feeding capacity in short crops such as brittle straw or sticky silage.
The 25-knife, High-Capacity Premium precutter features:
The - precutter function offers additional features such as:
The C451R Baler comes with a drop-floor unplugging system. In case of clog, the drop floor is managed from the display simultaneously or independently from the knives. When lowering the floor, the drop floor system provides 40-mm (1.57-in.) of free space under the rotor and converging augers.
By providing a constant free space, the John Deere drop floor avoids bottlenecks existing on balers using movable floors with front or rear hinges. No need to have an opening (that sometimes causes crop loss), only a few free centimeters (inches) are enough to remove the plug.
The worst plugs generally happen when turning with the baler. In such situations, the crops are blocked under the converging augers and the clog must be manually removed. The unique John Deere drop floor features a full width, protecting the full pickup and rotor width. Even when plugged at the converging auger level, the clog can be easily removed by the operator from the cab.
The C451R density is provided by an offset tension arm that applies hydraulic tension to the belts and not directly to the bale. This heavy-duty component is not involved in belt length compensation, so 100 percent of hydraulic power is involved in belt tensioning.
Density is easily set from the monitor and can be adjusted from 0 to 100 percent of hydraulic pressure. A virtual gauge located on the main working page continuously follows the density increase without looking back to the baler.
Density can also be adjusted manually from the hydraulic valve in case of major failure.
The C451R Round Baler features two wide 573-mm (22.56-in.) belts. Using two belts optimizes bale coverage and limits crop loss.
To handle the pressure transmitted by the density arm, the belts have no laces.
An advanced belt tracking system, including wide front pulleys and several guides located throughout the chamber, ensures accurate belt positioning, even when working in slopes or when overloading one side of the pickup. All edges of parts that could potentially come in contact with the belts are chamfered to avoid belt side damage. A take-up arm provides belt tension during the gate cycle process to avoid potential belt tracking issues.
Belts are driven by two large-diameter rubber rolls with a large contact surface to prevent belt slippage in wet conditions. Springs linked to the density arm are located on both sides of the chamber and give tension to the belts during bale starting.
The C451R has a few features to limit crop from sticking. The belts feature a smooth pattern. Paddles on belt drive rolls, cleaning augers into the density arm, and other scrapers located in several places through the belts paths continuously clean the belts and remove crop accumulation around the bale chamber.
MaxD bale chamber features three powered rolls:
Heavy bales, high density, high baling speed, and high tractor power directly impacts baler durability. The C451R Round Baler includes several heavy-duty components into the bale chamber to meet growers' expectations:
The C451R benefit from an advanced softcore system management:
Accurate softcore settings allow:

The size of the tailgate directly impacts bale transfer time, and the bale chamber unloading system is a critical component in a wrapping baler.
John Deere FRS greatly decreases non-productive time and directly boosts overall baler productivity.
There is an advantage to the baler compactness: by using a vertical folding structure, the C451R allows a quick transfer right after the bale has been unloaded from the chamber. FRS can close as soon as the bale leaves the unloading areas and the baling process can restart a short time after the bale has been ejected from the chamber.
On all other wrapping balers, the bale must first reach a far enough position before the tailgate can close (to avoid bale/tailgate interference risk). This transfer requires time and keeps the baler wrapping from restarting quickly.
FRS provides a light structure, less than half of the traditional tailgate weight that opens the chamber quickly and removes belts from the bale.
Compared to a traditional tailgate:
Moving side sheets help prevent the bale from getting stuck in the chamber. When the light structure opens, each side of the chamber automatically moves 50 mm (2 in.). There is no more contact between the bale and the chamber; the bale is released and quickly falls by its own weight. Even in wet conditions, the unloading process is as efficient as in dry straw.
This unique feature does not require complicated hydraulic or mechanical systems to be actuated. When the tailgate goes down, simple bearings push on cams located on both side sheets and lock the chamber sides in the baling position. When the tailgate opens, the pressure on the side sheets cam is automatically released, then a return spring quickly moves the chamber walls outside.
Locks located on both baler sides lock the FRS when the tailgate is closed.
The design of a productive baler is not sufficient if the film wrapping unit is not able to follow the same rhythm of work. John Deere engineers came up with smart solutions to eliminate bottle necks and boost total productivity.
Cycle times have been decreased and the system allows a bale wrapped with six layers of film every 39 seconds, meaning a maximum productivity of 92 bales per hour. This performance is from 7 percent to 22 percent better than others in the worldwide market.
To achieve such productivity, John Deere uses an innovative and powerful hydraulic motor which can drive the film wrapping arm at a 35-rpm speed.
The C451R is equipped with a unique film roll storage device. Each film roll weighs about 20 kg (44 lb) and must be changed often; this system has been designed to simplify loading and unloading operations.
On each side of the machine, five rolls are installed on a moving arm, hydraulically piloted. The loading/unloading position has been set up to be as close as possible to the wrapping arms at an ergonomic height.
Details count: in the transport position, the film storage device is covered by a roof which protects film rolls from rain. This protects the film roll core, often made of cardboard, from damage.
The C451R Wrapping Baler both use ISOBUS architecture and can be set from the display. There is no need for the operator to leave the cab, even for density or greasing (when equipped with optional automatic greasing system), as everything is managed from drop-down menus.

NOTE: Limited availability for model year 2019.
The C451R can be delivered with various monitors. At the top of the baler range, the 4240 Universal Display can be ordered. This monitor features a 21.5-cm (8.5-in.) diagonal color display. The touchscreen offers an intuitive and user-friendly interface that easily allows operators to adjust and control various settings.
To be used with ISOBUS or non-ISOBUS tractors, the GreenStar 4240 Display option is delivered with the following components:
NOTE: GreenStar™ 2 2600 Displays are not compatible. There is not sufficient memory to handle the software payload.
For operators already using a built-in or external ISOBUS certified display, the C451R Baler can be delivered without a monitor. Thanks to the ISOBUS connectivity, just plug the baler to the tractor/monitor and bale.
