D425, 500 and 575 Mixing Action

The same quality engineering that we use in our small mixers has been incorporated in the larger units. Through field-testing, we have designed the top augers to rotate in opposite directions. This design, along with having the right distance between the top augers, allows a faster mixing action and larger total load capacity.

D200, 250, 300 and 350 Mixing Action

The bottom augers rotate clockwise to work together moving material to the front of the mixer. The offset convergence point on bottom augers reduces torque which lowers horsepower requirements during tough mixing demands and gently lifts the feed to the top augers. To complete the mixing process, top augers move feed to the rear creating a waterfall-effect of feed cascading to the bottom augers for a thorough mix in half the time.

Enclosed Oil Bath

The entire drive system runs continuously in an enclosed oil bath for added protection and longer life. Simple chain and sprocket design is easy to maintain while providing efficient power transfer.

Easy–Access Rear Door(s)

Dual entry on models 425, 500 and 575, single on models 200, 250, 300 and 350. Behind these doors lie the latest innovation in Oswalt® drive technology. Large handles and a unique cam mechanism insure a tight seal for the oil bath while enabling quick and easy inspection access to the drive system.

Baffle Magnet Option

This option replaces the discharge chute. It bolts to the end of the conveyor and can be adjusted several ways to match feed flow and bunk requirements. The attached magnet helps trap unwanted metal.

Optional Light Kit

The optional light kit complies with ASAE standards for lighting and marking for operation on roadways.

Stationary Discharge Control

Offered on the D200, 250, 300 and 350 units. An 18" diameter wheel allows for manual operation of the sliding discharge door, controlling the flow of feed to the 20" wide discharge opening, for a complete cleanout to any conveyor. A lock positions the door to the desired opening. An optional electric door opener is available.

Dependable Dowel Drive

Provides superior power transfer to the augers. Plus, adds up to 80% more strength to the drive for rock-solid reliability in tough hay processing and mixing conditions.

No Maintenance Nyloil® Bearings

Sleeve–type, front, 63⁄4" diameter auger bearings are made from 1⁄2" thick Nyloil®. Nyloil® is a refined nylon material that is permanently impregnated with oil for superior lubrication, long life and smooth performance. These Nyloil® bearings are not affected by moisture, dust or the corrosive action of feed acid.

Rugged Lever Action Door

The wide 40" discharge door on the D425, 500 and 575 units is controlled with a hydraulic cylinder mounted to the sturdy body flange. This robust lever design transfers the pulling load to the rigid body instead of the side wall.

Heavy-duty Tires and Hubs

Massive H40 x 14.5 aircraft tires are mounted to heavy-duty hubs and axles which provide superior ground clearance and flotation for muddy conditions.

Operator’s Manual Holder

Permanently mounted to the mixer in a dry and secure location, the operator’s manual is always available for quick access and reference.

Double-Spherical Bearings

The Oswalt® D425, 500 and 575 have industrial duty double-spherical pillow block bearings that are designed for high loads and extended life.

Quick–Couple Auger Flange

Auger tube flanges are bolted directly to the drive shaft with four hardened bolts. This dependable design allows the augers to be quickly removed without opening the rear drive doors!

Centralized Grease Bank

Conveniently located on the side of the oil bath, this important feature helps reduce maintenance time and extends equipment life.

Hydraulically Adjustable Conveyor

This convenient hydraulic feature allows the operator to easily set the proper conveyor height for feeding into a bunk, minimizing wind loss. When you are done feeding, the conveyor folds up against the side of the mixer to allow maximum transport clearance. An extended folding conveyor is also available with an added 13" in length.

Stationary Motor Mount

Available on the D200, 250, 300 and 350 stationary units. Choice of right side (pictured) or front motor mount design featuring banded V-belt drive with easy belt tightening. Choose motor mount location based on feed room layout.

Optional Compression Load Cells

These CT load cells, when used with patented floating mounts, are ideal for truck mounted mixers giving you the most accurate and reliable scale system on the market today.

Multi–Position Swing Mount

This convenient and multi-position sturdy trailer swing arm mount lets the operator position the indicator for tractor seat or side viewing.

Weigh Beam Cells

We offer a four–point differential bending beam weighing system that is unmatched in accuracy and dependability. When used with one of the indicators you get an accurate ration, batch after batch.

Stationary Weigh Bars

The stationary models have four weigh beams that offer 99.5% accuracy. They feature heat-treated steel, sealed strain gauge design and choice of indicator. Load cells are mounted on a hefty channel frame.

Trailer Weigh Beam Axles

Models D200, D250, and D300 feature two weigh beam axles and weigh beam hitch with heat-treated steel and sealed electronic strain gauges. Model D350 features a four-point weigh beam mounting system. The indicator gives dependable and precise digital readouts at 99.5% accuracy, batch after batch.
