451M MegaWide pickup

A MegaWide pickup is base equipment on 451E, 451M, 461M, 551M, and 561M Round Balers.

Hydraulic pickup is in base configuration on 451R, 461M, 461R, 561M, 561R.

Hydraulic pickup is an option on 451E (dealer installed), 451M (factory installed), 551M (factory installed)

MegaWide pickups make baling easier, especially in wide or windblown windrows, and increases productivity; more hay volume means more bales per hour.

Flare-to-flare width of 1.8 m (5.9 ft) on balers with a 1.2 m (4-ft) wide bale chamber
MegaWide pickup makes it easier to produce better-shaped bales and improves crop pickup in wide, windblown, or scattered windrows
Mega teeth, located at the ends of the pickup, pull crop around the flares when baling wide or windblown windrows
MegaTough pickup teeth provide greater strength and durability
Exclusive square design handles high-impact loads without yielding
Sturdy toothbar design
Self-adjusting roller baffle
Spiral rotor-feed system improves feeding in all crop conditions
Chain driven for positive feeding
Cut-out clutch protected
Semi-pneumatic gauge wheels

MegaTough pickup teeth

Mega and MegaTough pickup teeth are base equipment:

Mega teeth, at the ends of the pickup, are heavy-duty for long life and improved crop retrieval
MegaTough pickup teeth are designed to withstand the harshest baling conditions and provide long service life

Toothbars on 1.5-m (5-ft) baler

The 1.2-m (4-ft) balers use a full-length, reinforced toothbar design.

The 1.5-m (5-ft) balers use a heavy, C-channel construction. The pickup toothbars are divided into two half-sections that mount to a center spider for increased strength and even crop feeding.

Roller baffle

Available only on the MegaWide Plus pickup, the patented roller baffle is self-adjusting and produces smoother crop flow across the pickup. The roller also improves crop pickup in small windrows and prevents roll ahead of crop.

When combined with the MegaWide Plus pickup, this feeding system allows increased ground speed with less chance of plugging for increased productivity in all field conditions.

Self-adjusting
Smooths crop for even flow across pickup
Allows for faster ground speed with less chance of plugging
Increases operator productivity

Spiral rotor

Auger and rotor feed system

The MegaWide Plus pickup uses a rotor-feeding assembly, which mounts behind the pickup for smooth and even crop flow into the bale chamber.

Augers and rotor teeth are driven on the same shaft, eliminating the need for additional drives.
The rotor is fixed to the baler frame, allowing positive and even feeding into the bale chamber.
Large-diameter converging augers have high crop-flow capacity, and auger scrolls help to force crop into the chamber.
Spiral design enhances feeding in uneven windrows and reduces loading on the rotor.

Rotor stripper

Rotor strippers allow crop to be lifted from the rotor teeth into the chamber without cutting or wrapping the crop.

Cut-out clutch protection and feeder-drive chain

The MegaWide Plus pickups and spiral rotor are chain-driven for positive bale starts with cutout clutch protection. The pickup is being driven off the drive roll and bypasses the starter roll. This will allow for reduced wear and breakage of the starter roll chain.

Adjustable crank handle

The adjusting crank positions the pickup to the desired operating height to match crop or field conditions.

An optional hydraulic pickup lift cylinder is available as an attachment.

Makes raising for transport or clearing obstructions easy
Crank handle serves as a down stop
Adapts to regular, MegaTooth and MegaWide Plus pickups
Hydraulic pickup lift comes standard on premium machines

Heavy Duty Package

The heavy duty package is standard equipment on R series balers and option on M series balers. The components and features of the heavy duty package are below.

Two year or 12,000 bale Warranty
Cam-Cut Out Clutch
Heavy-Duty Chain
Pickup - Heavier Spider Gear, Cam Arm Bearings, Cam Shafts, and Bearings in Spider
Larger Diameter Shaft and Bearings on #11 and #9 rolls

Semi-pneumatic gauge wheel

Semi-pneumatic gauge wheels provide smooth ground gauging over uneven terrain and protection to the pickup.

Stiffer rubber sidewalls
No air pressure to maintain, which mean no flat tires
Adjustable to meet pickup tooth-to-stubble height requirements

The pickup float springs are positioned for excellent flotation.

Adjustable to meet varying field conditions
Float springs only support the pickup reel
- Rotor assembly is fixed to the baler frame, eliminating additional weight on the pickup system

Silage configuration

Staggered roller-auger kit

A silage-configuration baler allows the producer to put up silage hay. A silage configuration machine does not offer a precutter. There are three major components to a silage configuration baler: a staggered roller-auger kit (1), a starter roll-scraper knife, and a screen (2). The powered auger sits above the staggered roll on the baler to help keep wet hay from traveling up the belts and reduce buildup on the roll. The screen is bolted on the front of the baler as a safety feature. The knife/scraper is mounted in front of the starter roll to help prevent wrapping of wet crop on the starter roll.

The silage kit is offered as a bundle for field installation if the baler is not ordered as a silage-configuration machine from the factory. Attachment BE32442 is for 1.22-m (4-ft) wide machines and BE32443 is for1.52-m (5-ft) wide machines.

Also offered is a high-moisture kit. This kit does not include the same components that are on the silage-configuration balers. It offers the starter roll-scraper knife but does not include the staggered roll-auger kit. Attachment BE23828 is for 1.22-m (4-ft) machines and BE23829 is for 1.52-m (5-ft) machines.

Starter roll knife and screen

Base equipment on: 451M Silage, 551M Silage, 461M Silage, 561M Silage, 451R Precutter, 461M, 461R Precutter, 561M and 561R Precutter

Auxiliary take-up rolls

Auxiliary take-up rolls prevent belt crossover and flipping in wet conditions. This roll is base equipment on all silage and precutter configuration balers.

Regular pickup offers large feed opening and low-profile, mid-mounted pickup

The compressor rack can be adjusted upward or downward to match the volume of material in the windrow and can be easily removed to match crop conditions.

Adjustable crank handle

The adjusting crank positions the pickup to the desired operating height to match crop or field conditions.

An optional hydraulic pickup lift cylinder is available as an attachment.

Makes raising for transport or clearing obstructions easy
Crank handle serves as a down stop
Adapts to regular and MegaWide™ Plus pickups
Hydraulic pickup lift comes standard on premium machines

NOTE: Crank is not an option for the MegaWide High Capacity and Cutting (HC²) feed system.

Automatic electric-tie option using G5e monitor allows for more productivity

Audible alarm

G5e monitor-controller

The G5e monitor-controller is included with the automatic electric twine tie option and the Edge-to-Edge net wrap option on the 451E Baler. The monitor sounds an alarm for near-full, full, and oversized bales.

Monitor beeps once to notify the operator to even-up the bale prior to reaching the desired size.
Monitor beeps twice when the bale reaches the desired size.

If the operator continues to feed hay into the baler, the monitor will sound continuously to warn of an oversized bale.

Bale shape bars are in base on the 451E Round Balers.
The 451E Round Balers allow for adjustment of twine settings from the cab by using the G5e monitor.
The number of wraps on the Edge-to-Edge net wrap option on the 451E can be set with the G5e monitor.

The audible level of the monitor can be adjusted.

Adjustable hitch to match wide array of tractor drawbar heights

Side view of adjustable hitch

Front view of adjustable hitch

The 1 Series Round Balers came standard with an adjustable hitch and this feature will continue to be in base with the 1 Series Round Balers. This feature allows the hitch height to be adjusted to optimize crop-feeding performance. Due to the wide array of tractor tire sizes and drawbar heights, hitch adjustment may be necessary to get the proper feed opening of the baler. The adjustable hitch eliminates the need for the 51-mm (2-in.) thick tractor drawbar kit (AE57344) because it has a wider opening.

Benefits of the adjustable hitch:

Ability to match baler to numerous tire sizes
Allows for drawbar height to fall within 330 mm to 559 mm (13 in. to 22 in.) from the top of the drawbar to the ground
Eliminates narrow feed opening on the baler which can cause plugging
Allows pickup head to follow terrain without missing crop

All eight bolts must be used when adjusting the hitch. There are four different positions as shown below:

Position 1 (top) (factory setting) - regular pickups

Position 2

Position 3 (factory setting) - MegaWide

Position 4 (bottom)

Also standard on all 1 Series Round Balers, except the 451E, is the drawbar shield. This helps to eliminate hay from getting caught on the hitch of the baler. The drawbar shield is designed to allow the operator to remove or attach the flap without having to unhook the baler from the tractor.

Let the baler do the work with Baler Automation

Baler Automation display screen

Due to shrinking management windows and growing workloads, it’s more important than ever to reduce operator fatigue and maintain efficiency. Baling operations have become complex, and it’s easy to make mistakes after a long day of baling. Eliminate baling errors, get more hay baled, and get home sooner when using Baler Automation.

Reduce the number of baling tasks
- Baler Automation Select MSCV – The baler opens and closes the gate automatically after the tie cycle.
- Baler Automation Select (Gate cycle open.close + Tractor Start/Stop – If the tractor has an infinitely variable transmission (IVT™) or e23™ transmission (7R only), the baler will command the tractor to stop then open and close the gate after the tie cycle.
Reduce baling errors
- Less premature opening of the gate
- Fewer bales need to be unrolled and re-baled
Save time as fatigue and bale count increases

Vertical forming chamber maintains uniform bale density

Bale-starting diagram

As the hay enters the forming chamber from the pickup, belts immediately turn the hay to form a tight, dense core.

Incoming hay then feeds between the bale and the lower gate roll. Hay is tightly compressed into smooth, dense layers as it enters the bale.

Chaffing is greatly reduced to prevent loss and retain hay quality in the bale.

Full-sized bale in bale chamber

The idler arm rises with bale growth, forcing oil from the hydraulic cylinder through a pressure-relief valve to maintain uniform bale density throughout the bale-forming process.

Exclusive DiamondTough™ belts with plate-type splices

Staggered belts

John Deere's 178-mm (7-in.) wide diamond-tread design ensures fast bale starts and grips the bale to prevent slippage and reduce chaffing. The treads are self-cleaning to reduce carryover. The belts are staggered to reduce the loss of fine material and are closely spaced to contain the hay for fast, easy starts.

The belts enclose 91 percent of the bale width to reduce loss of fine material and retain hay quality.

The staggered belt roll design enables any loose hay under or behind the belts to be returned to the pickup and into the baler. This design helps to prevent buildup at the front of the baler, which could cause hay loss and belt or splice damage.

DiamondTough triple-weave belts

Every baler in the 1 Series Family uses DiamondTough belts. Belts are constructed using a patented triple-weave process of nylon and polyester materials.

They have the strength to handle heavy shock loads and help maintain consistent belt length.

The DiamondTough belts are more puncture and tear resistant than other belts on the market and provide improved belt life and reliability.

Plate-type fasteners

Plate-type splices

All of the 1 Series Balers use the plate-type fasteners.

This closed-loop design uses a plate fastener with pre-assembled rivets that lock the fasteners into the belt, providing a powerful vice-type grip on the belt.

The plates and rivets are manufactured from high-tensile stainless steel.
Strong belt splices mean less maintenance and more productivity.
The loop area is cold forged, making it extremely wear resistant in the coupling area, resulting in a very long cycle life.
The spring steel pin is notched and locks into the splice connection without having to bend the pin or use external retainers.

Additional features available on the 1 Series Round Balers

All M- and R-specification 1 Series Balers have the same stamped, steel door design.

Factory-installed grease bank

Grease bank

Standard on premium round balers is a factory-installed grease bank. This allows the operator to only have to grease eight zerks (four on each side of the baler) for grease zerks that were hard to reach on previous models. The operator will still have to grease the driveline and some other components on the baler.

NOTE: The grease bank will also be found on all 1 Series precutter configuration balers.

ISOBUS system

Connection of ISO monitor wiring harness to the tractor

Controller on baler

The ISOBUS system offered on the premium round balers allows the operator to use the latest technology when baling. They can utilize their GreenStar™ 2600, GreenStar 2630, GreenStar 1800, or certain R-Series CommandCenter displays as their baling monitor and can switch between tractors without having to take the display with them. All information for the baler is stored on the controller.

Warranty

A two-year or 12,000-bale warranty comes standard on 460R Premium and 560R Premium Round Balers only. Please see full product warranty for more details.
