The idler arm rises with bale growth, forcing oil from the hydraulic cylinder through a pressure-relief valve:
A MegaWide Plus pickup is available on 448, 458, 558, and 568 Round Balers. It is base equipment on the 458 Silage Special, 468, and 468 Silage Special.
This pickup makes baling easier, especially in wide or windblown windrows, and increases productivity; more hay volume means more bales per hour.
Mega and MegaTough pickup teeth are base equipment:
MegaTough pickup teeth are designed to withstand the harshest baling conditions and provide long service life
The 4-ft balers use a reinforced toothbar design of MegaTooth™ pickup.
The 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.
Available only on the MegaWide Plus pickup, the patented roller baffle is self-adjusting and produces smoother crop flow across the pickup.
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.
The MegaWide Plus pickup uses a rotor feeding assembly, which mounts behind the pickup for smooth and even crop flow into the bale chamber.
Rotor strippers allow crop to be lifted from the rotor teeth into the bale chamber without cutting or wrapping the crop.
The balers are chain-driven for positive bale starts with cutout clutch protection.
A 24-bar graph makes it even easier to make a uniform-shaped bale that will stand tall and remain firm over time. The 24 bars provide smaller increments of change to give the operator a more precise indication of bale shape.
BaleTrak Pro has a manual twine arm override switch (A), which is included with the monitor's wiring.:
Mounted in front of the baler wheels and directly below the bale chamber, the pickup hugs the ground for clean crop retrieval. Hay movement is minimized.
The small-diameter, low-profile pickup is mounted close to the baler wheels for good ground gauging and clean crop retrieval:
Side flares prevent hay from blowing off the pickup ends and reduce hay loss.
The closely spaced pickup teeth extend to the baler side sheets to help build straight-edged bales.
Standard on regular and MegaTooth™ pickups, 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 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.
An optional hydraulic pickup lift cylinder is available as an attachment.
John Deere's 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.
The 458, 458 Silage Special, 558, 468, 468 Silage Special, and 568 use 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.
The COVER-EDGE surface wrap bundle is available on 458, 458 Silage Special, 558, 468, 468 Silage Special, and 568 Round Balers. This attachment is an exclusive feature of 7 Series and 8 Series Balers.
The COVER-EDGE net wrap stretches over the edges of the bale to cover 15 percent more surface area on the bale. This added feature allows better weatherability by shedding water off the ends of the bale and increases marketability, due to less crop spoilage and a better-looking bale.
On the 458, 458 Silage Special, 558, 468, 468 Silage Special, and 568, the BaleTrak™ Pro monitor-controller can automatically adjust twine or net-wrap application to compensate for a revised bale-diameter setting or a smaller size when finishing up a field.
The operator just presses the wrap symbol on the BaleTrak Pro monitor-controller to initiate this command.
If running less-than-rated PTO speed, the slip clutch alert/speed compensation option compensates the number of wraps selected for a bale. Without the slip clutch alert/speed compensation option, the wrapping program is based on the rated PTO speed.
NOTE: Edge-to-Edge net-wrap material works in the 7 Series and 8 Series COVER-EDGE surface wrap attachment. Refer to the round baler operator's manual for proper adjustment. Plugs are available through AMBRACO to center the roll in the attachment.
Standard only on balers with COVER-EDGE surface wrap, drop-down lube lines have been installed to make servicing the bale-shape senders more convenient.
