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 tine bars. The cam lever is made of forged steel. All these features guarantee a long component life and low maintenance.

Premium pickup pushes harvesting capacity a step forward

The C451R Wrapping Baler is designed for the most demanding operators. The pickup features only premium components and concepts such as:

• 2.2-m (7.2-ft) wide pickup, with a 1.92-m (6.3-ft) tine-to-tine distance - this important width provides comfort and speed capacity when harvesting the largest swaths.
• Five tine bars - the fifth bar allows the tines to rake two more times per second versus the John Deere standard four-tine pickup.
• O-shaped tubular tine bars with central spider reinforcement - tine bars are assembled with ball bearings on the central spider, and central spiders highly limit tine bars bending in the very heavy crops.
• 6mm (0.23-in.) diameter galvanized tines with high strength to harvest the toughest crops.
• Tines are designed to fold to replace potential shear bolt or cam clutch overload safety. 6-mm (0.23-in.) diameter tines push pickup maximum intake capacity up to 18 kW (24.1 hp), a value often not reached by machines using cam or shear bolt protected pickup.
• Stainless-steel strippers (exclusive feature) that give highly durable rust protection, perfect gliding capacity no matter the material, and is much more resistant to acid damage caused by additive uses (propionic acid).

The C451R and C461R Balers use the premium pickup that is also equipped on high-spec V4X1R Variable Chamber Balers. To fit all conditions, the baler is available with a 2-m (6.56-ft) or 2.2-m (7.22-ft) width.

The pickup, driven by 19.05-mm (0.75-in.) heavy-duty chains, features five tubular tine bars with a low rotating speed. The large-diameter strippers allow five tine bars in the pickup. With bearings added to the cam track, all these features provide a smooth and quiet ride with extended uptime.

In addition to the high-spec features, the C451R and C461R benefit from stainless-steel strippers, a market exclusive. Stainless steel provides the following advantages:

• No rust
• Constant gliding capacity
• High resistance to aggressive additives such as propionic acids

The C451R and C461R Balers pickup uses the cam-track design, providing a better solution to harvesting wet crops. Contrary to the cam-less design, the cam track

• pickup: Features a short space between the tines and rotor, limiting dead zone
• Avoids pinching area, so no crops are plugged into the pickup drums

High-capacity (HC) rotor for higher productivity and durability

To maximize productivity in the toughest swaths, the F441R Baler features an HC Premium rotor design. Exclusive 48-cm (18.9-in.) converging augers are aligned with the rotor, limiting the free space between pickup teeth and rotor. Plugging risk is also decreased and crop transfer is highly improved. The simple HC Premium rotor design also reduces the number of moving parts and provides reliability. For example, stress on the rotor is distributed along the rotor to avoid overhang load on the bearings.

Additionally, all rotors feature tines that are made of Hardox® wear plate which drastically improves wear resistance, especially in rocky fields (Hardox wear plate tines provide 80 percent or more resistance versus traditional S700 grade steel).

The C451R and C461R are only available with a precutter, offering space between knives as short as 40 mm (1.57 in.) or 80 mm (3.15 in.).

High cutting quality provides better forage

The C451R and C461R Balers are efficient in baling a high amount of cut silage. The MaxiCut HC 13 Premium and MaxiCut HC 25 Premium feature exclusive high- quality knives, providing several advantages:

• Bulk heat treatment to reduce risk of knife breakage.
• Surface heat treatment of the cutting area to provide better cutting quality and knife durability.

A knife slot fillers set is delivered as standard with all machines featuring the precutter. When using the MaxiCut HC Premium pickup without knives, dust and harvest matter can fill knife slots. This keeps the knives from returning to the cutting position, and plugs must be manually removed to free the knives.

Select number of knives from the cab to increase uptime

The C451R and C461R can be used on several kinds of crops, in which knives can be engaged or removed. No matter the rotor type or monitor, this operation is easily managed from the cab.

When using the MaxiCut HC 25 Premium precutter, crops can be cut as short as 40 mm (1.57 in.), but only half of the knives can be engaged. This system proposes to use two different sets of knives for the same cutting width, to allow the use of sharp knives longer. By using sharpened knives versus blunt, fuel consumption can be decreased by up to 10 percent.

Drop floor can remove the worst plugs

No matter the operator experience, plugs can still occur, especially with large silage swaths. The C451R and C461R are equipped as a base with a drop floor unplugging system. The drop floor features exclusive advantages, such as:

• Full-width design - by covering the full pickup width, the device can remove plugs, even located under converging augers.
• Parallel kinematic - no rear or front hinge means no narrowing. The F441R drop floor offers a constant 40-mm (1.6-in.) free space through the feeding channel when activated. This is enough to decompress the crops and avoid crop loss.

No matter the precutter or monitor type, the drop floor unplugging system can be easily managed from the cab.

The C451R benefits from the proven HC rotor concept, featuring an in-line design

By using the HC premium rotor – a device available on John Deere round balers since 2012 – the C451R feeding system offers:

• Limited distance from the pickup to rotor tines to reduce plugging, especially in brittle straw or short silage
• Reduced number of bearings and distributed loads along the rotor to increase reliability
• Large 48-cm (18.9-in.) diameter converging augers facilitate crop transfer

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.

MaxiCut™ HC 13 Premium rotor offers standard cutting length coupled with high productivity and versatility

The C451R Wrapping Baler can be delivered with a MaxiCut HC 13 Premium rotor.

The rotor features:

• Close to 50-cm (19.7-in.) diameter rotor for high inertia and feeding capacity.
• Hardox® wear plate material (similar to R-Series) to provide a long lifespan and high resistance to foreign objects (Hardox wear plate tines provide 80 percent or more resistance versus traditional S700 grade steel).
• Three tines per turn (instead of two on G-Series RotoFlow HC)
• Tines fully enclosing the tube (instead of spikes on G-Series RotoFlow HC), giving higher tine resistance and longer component lifetime
• 0/13 knives engagement from the display. No need to leave the cab to manage knives.
• 80-mm (3.1-in.) knife spacing when all knives are engaged, a standard cutting length that gives a good compromise between crop quality and power consumption.
• Heavy-duty knives thanks to the double hardening and tempering treatment. Crops are perfectly cut for long, requiring less fuel consumption and sharpening operations.
• Individually spring-loaded knives to avoid component damages when grabbing foreign objects. Compared to a shear bolt or full-set hydraulic system, this technology limits the effort on the knives and/or provides non-stop safety.

MaxiCut HC 25 Premium provides high-quality fine chopped crops

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:

• Close to 50-cm (19.7-in.) diameter rotor for high inertia and feeding capacity.
• Hardox wear plate material (similar to R-Series) to provide a long lifespan and high resistance to foreign objects (Hardox wear plate tines provide 80 percent or more resistance versus traditional S700 grade steel).
• Three tines per turn (instead of two on G-Series RotoFlow HC).
• Tines fully enclosing the tube (instead of spikes on G-Series RotoFlow HC), giving higher tine resistance and longer component lifetime.

The fine-chop precutter function offers additional features such as:

• 0/12/13/25 knife engagement from the display. No need to leave the cab to manage knives. When used alone, the 12 or 13 knives set provides a regular 80-mm (3.1-in.) knife spacing and limited power consumption. When paired together, knife spacing is reduced to 40 mm (1.6 in.).
• Heavy-duty knives thanks to the double-hardening and tempering treatment. Crops are perfectly cut for long, requiring less fuel consumption and sharpening operations. When cutting at a regular 80-mm (31-in.) length, the two independent knife sets extend time between each sharpening process by using the first knife set one day and the second one on the next day (time between each sharpening process given can vary greatly depending on crop type and number of bales).
• Individually spring-loaded knives to avoid component damage when grabbing foreign objects. Compared to a shear bolt or full-set hydraulic system, this technology limits effort on the knives and/or provides a real non-stop safety.

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.
