MegaWide™ Classic pickup provides increased feeding capacity
451E MegaWide Classic pickup
The MegaWide Classic pickup is an exclusive update to the 451E round baler feeding system. Providing a wider pickup and a spiral rotor for improved crop feeding and pickup capacity, the MegaWide Classic pickup works to increase baling efficiency. Features include:
- 32 percent wider pickup (in comparison to the MegaWide pickup)
- 180-cm (71-in.) flare to flare width
- Regular Duty pickup teeth
- Shear Bolt Protection
- Guage Wheel package available
- Optional hydraulic pickup lift cylinder available
The small-diameter, low-profile pickup allows for good ground gauging and clean crop retrieval.
- Handles large, heavy windrows of hay and high-moisture crops
- Feeds hay directly to the forming chamber to reduce crop loss
- Low-profile pickup minimizes hay lift to reduce chaffing and retain hay quality
Compressor rods are contoured to control hay over the pickup radius for positive feeding. 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.
The adjusting crank positions the pickup to the desired operating height to match crop or field conditions.
Adjustable crank handle
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.
G5e external speaker
G5e External Speaker Device
G5e External Speaker Device
The G5e External Speaker is an optional attachment for G5e displays only.
- Provides increased volume levels for all G5e display notifications
- Assist baling operations in situations with high in-cab noise or for operators with hearing impairments
- Installed externally on harness for easy access
- Omits sound separate from G5e display speaker to increase volume up to 16 percent
- Manually adjust volume by turning front dial left or right
The external speaker device provides increased volume levels for all G5e display notifications. It will omit a sound separate from the G5e display to assist baling operations in situations with high in-cab noise or for operators with hearing impairments. It is installed externally on the harness and can have volume levels changed by manually turning the front dial left or right. Adding the external speaker increases G5e notification volume by 16 percent. The external speaker is optional and is available as an attachment.
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. 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
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.
