      The 4500 frame features a bolted construction. The 1/2" bolts and lock nuts fasten the cross members to the main stringers every 24". You won't find any sheet metal in the Meyer frame.




TSS Control Panel - Simple yet Efficient
The TSS design allows the operator more speed selections with less moving parts. Low range is 0 - 7'6"/mn. High range gives you the fastest clean-out in the industry - up to 17'/mn.
Plus, the Independent Cross Conveyor Clutch allows you to feather start your cross conveyor on big loads.

Cross Conveyor Extension
A convenient cross conveyor extension is available to accomodate large tires or hard to get at spots. It extends out 24" and can be folded up when traveling.

Low Maintenance - Easy Access
All roller chains have automatic nylon tighteners. Auger and conveyor bearings are sealed for your convenience. Variable speed sheaves have 1/2" drive pins, not 3/8".

TSS Auger Design
Auger Feathering System allows the operator to inch

the augers clean without bringing the load forward.

This is accomplished through the variable speed drive.

No extra belts.  Notice the large 18" augers (not beaters)

are tapered back more than others for the most even feed on the market.

Open Top Option
Available with or without height extension on all models. All open tops come standard with side support kit

High Volume Options
12" taller sides for maximum capacity. (Includes side support kit). Available with or without roof
6" taller roof with standard side height.
