Variable Chamber Wrapping Baler
Cam-track technology provides an efficient solution for such needs. The traditional stripper design provides reduced space between the pickup tines and rotor feeder, while the tine motion helps to avoids pinching.
The cam-less technology requires long strippers, creating a dead zone between the tines and rotor. Additionally, fixed tines can easily pinch crops in sticky conditions, causing plugs that need to be manually removed.
The cam-track pickup features a low turning speed and big bearings on both side of the tines bars. The cam lever is made of forged steel. All these features guarantee a long component life and low maintenance.
The C451R Wrapping Baler is designed for the most demanding operators. The pickup features only premium components and concepts such as:
By using the HC premium rotor – a device available on John Deere round balers since 2012 – the C451R feeding system offers:
The overall result is optimized crop flow that avoids all dead area where crops stay for a long time.
This smooth and regular crop flow guarantees high feeding capacity, especially in short crops such as brittle straw or sticky silage.
The C451R Wrapping Baler can be delivered with a MaxiCut HC 13 Premium rotor.
The rotor features:
For enhanced forage quality or for special application (poultry bedding, fruits, and vegetables application), MaxiCut HC 25 Premium can be assembled on R-Series Balers.
As with the RotoFlow HC Premium or MaxiCut HC 13 Premium, this fine chop precutter features:
The fine-chop 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 parallel kinematic has 40-mm (1.57-in.) extra 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 a huge 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 C461R can produce bales from 0.8 m (non-wrapped materials) or 1.0 m (wrapped crops) up to 1.70-m (5.58-ft) diameter with a 1.21-m (4-ft) bale chamber width.The diameter of wrapped bales can be pushed up to 1.45-m (4.76-ft).
The MaxD – Maximum Density – bale chamber has been designed to deliver very heavy, dense, and perfectly shaped bales, officially proven by DLG.
The C461R 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 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 and C461R both benefit from a standard advanced softcore system management:
Accurate softcore settings allow:

The C461R Round Balers feature two wide 573-mm (22.56-in.) belts, meaning that only three free spaces are observed (one between the two belts plus one on each belt side). Compared to a traditional 5/6 belts solution, only using two belts optimizes bale coverage by approximately 4 percent. The result is significant crop loss limitation and more efficient baling process.
In order to handle huge stress transmitted by the density arm, the belts have no lacers.
An advanced belt tracking system, including wide front pulleys and several guides located everywhere through the chamber, ensure accurate belt positioning, even when working in slopes or when overloading one pickup side. All edges of parts potentially in contact with the belts are chamfered to avoid belt side damage. A take-up arm manages belt tension compensation during the unloading process to avoid potential belt tracking issues.
Belts are driven by two large-diameter rubber rolls with a large contact surface that avoids belt slippage in very wet conditions. Springs linked to the density arm are located on both sides of the chamber and give enough tension to the belts from bale starting.
To limit crops from sticking, belts feature a smooth pattern. Paddles on the belts' driving 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 to improve versatility and bale quality:
Heavy bales, high density, high baling speed, and high tractor power directly impacts baler durability. The C461R Round Baler includes several heavy-duty components into the bale chamber to meet growers’ expectations:
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. As summarized by an official DLG Fokus test 6112F: "The signature trait of this baler is the innovative ejection system, which provides considerable advantage through a very short bale ejection time. This shortens the hold time of the baler during ejection, which can consequently lead to a higher rate of 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 picking 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 the worst 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 side lock the FRS when tailgate is closed.
The design of a very efficient and 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.
The core trick to achieve such productivity is in an innovative and powerful hydraulic motor which can drive the film wrapping arm over 35 rpm speed (a record on the market) and without any compromise for operator safety, as an integrated and automatic brake could stop every motion in a short time.
The C451R and C461R are equipped with a unique film roll storage device. Each film roll weighs about 20 kg (44 lb) and must be changed very 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. Managed by a control panel standing on both sides of the baler, the system prevents the operator from running from the left side to the right side to operate storage racks, as is the case on several competitive wrapping balers. The loading/unloading position has been set up to be as close as possible to the wrapping arms at a very 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 uses ISOBUS architecture and can be fully set from the display. There is no need for the operator to leave the cab, even for density or greasing parameters (when equipped with optional automatic greasing system), as everything is managed from drop-down menus.
The C451R offers:
