OPERATION MANUAL INTRODUCTION
TO THE NEW OPERATOR OR OWNER
Since 1986 Pik Rite equipment has been developed by people who work as hard as you do in the
fields, on the farm and on site. Our goal is to deliver products that get the job done with the most
efficient results. If you want tough, dependable people and products you can count on, we’ve got
your back.
This manual is provided to all our customers of newly manufactured manure spreaders to create
an awareness of all maintenance expectations and dangers that may be encountered when
owning this equipment. This manual should be kept for all future references. Please review these
operating instructions carefully, then sign and date the last page of this document and return it to
Pik Rite Inc. for processing. This will activate your warranty and verify that you have read and
understand the following operating instructions and warnings. In the event you have questions
or encounter other applications not discussed in this manual, please call before proceeding.
Congratulations and Thank You for choosing a quality manure spreader manufactured by Pik
Rite Inc. We believe you’ll be very satisfied with the purchase, and we appreciate your patronage.
PRINCIPLES OF OPERATION
The legacy of the 2-stage hydraulic push began with the John Deere Hydra-Push spreaders. Pik
Rite continues the tradition with the Hydra-Ram series, which are designed to efficiently and
uniformly spread manure. Equipped with a double hydraulic cylinder these spreaders also have a
sliding floor. Each Hydra-Ram spreader is built to withstand the demands of farm life. All side
and floor panels are constructed with a laminated poly covered finish for maximum strength and
durability.
Less Compaction –This line of tough machines uses both a sliding floor and a moving front panel
to deliver the material to the beaters. The sliding floor is pushed back first, using an engineered
hydraulic cylinder. When fully extended, the front panel moves back to unload the box
completely.
Less Maintenance –The Hydra-Ram is engineered to get the job done with fewer moving parts.
This design efficiency extends the life of the spreader while requiring less maintenance and
down-time than other manufacturer’s equipment. Auger systems tend to compact the material
into clumps, causing uneven distribution and increased wear on the beater system. The 2-stage
hydraulic push technology greatly reduces compaction and provides optimal clean-out.
Less Time, Spread Faster –The Hydra-Ram 2-stage push system delivers the material to the
beaters at an even and controlled speed. Manual and/or electric over hydraulic flow controls
allow you to unload the material faster than auger or side sling machines.

SAFETY
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin causing serious
injury.
Avoid the hazard by relieving pressure before disconnecting hydraulic or
other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from
high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into the
skin must be surgically removed within a few hours or gangrene may
result. Doctors unfamiliar with this type of injury should reference a
knowledgeable medical source.
SERVICE SPREADER SAFELY
To help prevent personal injury caused by unexpected movement, be sure
to service spreader on level surface.
If spreader is connected to tractor, disengage PTO, engage parking brake
and/or place transmission in “PARK,” shut off engine and remove key.
If spreader is detached from tractor, block wheels and use safety stands to
prevent movement.
Replace all shields after lubricating or servicing.
REDUCE SPEED WHEN TOWING LOADS
Braking to stop towed loads from transport speeds can cause the towed
load to swerve and upset. Reduce speed if towed load weighs more than
the tractor and is not equipped with brakes.
Follow recommended speed-weight ratio guidelines:
• Maximum speed is 20 mph (32 km/h) when towing loads equal to or
less than the tractor.
• Reduce speed to 10 mph (16 km/h) when towing loads more than equal
and up to double the tractor weight.
• Do not tow loads exceeding double the tractor weight.
• Use additional caution when towing loads under adverse surface
conditions, when turning, and on inclines
