Meyer Manufacturing BOSS Series Forage Boxes

Description

The Meyer BOSS Series Rear Unload Forage Boxes are engineered for maximum capacity, fast unloads, and trouble-free service in today’s toughest forage operations. Available in three heavy-duty series—100, 8100, and 9100 BOSS—these boxes deliver reliable performance for silage, haylage, and high-moisture crops, whether you’re hauling on a wagon, truck, or trailer.

Every BOSS Series box features Meyer’s exclusive twin apron chain drive system and variable speed direct drive for quick, even unloading with minimal crop damage. High-strength steel construction, tall sides, and wide boxes mean you can handle massive loads without worry. The BOSS Series is designed for flexibility—choose standard or extra-tall extensions for even more capacity, and select the right length for your operation.

From dairy and beef producers to custom harvesters, Meyer BOSS Series rear unload forage boxes help you keep the crop moving and the harvest on schedule—backed by Parallel Ag’s trusted sales and support team.

Features

Fast, Stable, Safe Unloading

No-Hoist Design.
A hydraulic geardrive system unloads the full box without a hoist, cutting unload time to roughly 40-65 seconds depending on model.

Big 2-3/8 in. Driveshaft.
A heavy-duty solid driveshaft replaces roller chains for efficient, low-maintenance power to the apron.

Dual Geardrive on Larger Models.
9100 RT BOSS models and the 8126RT step up to a dual hydraulic geardrive for consistent power on bigger loads.

Built for Capacity and Durability

HD Fully Welded Frame.
A rigid frame on 16 in. centers handles heavy loads while keeping a low center of gravity.

Solid Poly Floor.
A high-molecular virgin poly floor (not reground) reduces drag and resists wear.

Durable Side Panels.
Clad-Tuff fiberglass woven sides come standard on 8100 RT BOSS models, with stainless steel sides standard on 9100 RT BOSS models.

14 in. Side Extensions.
Optional removable extensions add capacity on every model without changing the box footprint.

Flexible Configuration Options

Multiple Mount Types.
Choose truck mount, chassis-cart mount, wagon mount, or semi “Ag” trailer mount to match your operation.

Automatic Rear Gate Delay.
The rear door opens, closes, and latches on its own, with barn door and grain kit options available.

Reversing Apron Option.
This option makes the BOSS Series a strong fit for hauling bales or partial loads, not just chopped forage.

Electric Tarp Systems.
Front-to-back scissor or side-to-side roll tarp packages are available across the lineup.
