GENERAL INFORMATION
The operator must read and understand the information in this
manual to ensure the correct service and operation of the machine
and avoid unnecessary risk of accidents and breakdowns.
Please Note:
Stop the tractor engine before you adjust, lubricate, or repair the machine. Remember to
remove the ignition key to make sure no one starts the tractor while you are repairing the
machine.
Do not let anyone underneath the machine once it is connected to the tractor. Always
disconnect power when servicing.
Do not let anyone get close to or stay close to the machine while it is in operation. Do not
squeeze between the machine and the tractor as an unintentional maneuver may result in
serious injury.
Make certain that the hydraulic components are not subjected to continuous operating
pressure exceeding 1800 psi or intermittent pressures of 2350 psi. A higher pressure may
cause danger of exploding parts, hot oil exposure, or component failure.
Tractor Requirements:
It is recommended that the tractor operator use hearing protection in case of insufficient
sound insulation in the cab. In order to keep full control of the tractor in all circumstances, at
least 20% of the tractor’s total weight should be on the front axle. It may be necessary to
regulate weight distribution with additional weights.
Do not overload your vehicle beyond the manufacturer’s payload limits. If there are any
questions concerning weight limits, contact vehicle manufacturer.
Material Density Guideline*
Fine Salt (Dry)
85 lbs./cubic foot
Coarse Salt (Dry)
55 lbs./cubic foot
50/50 Sand/Salt Mix
100 lbs./cubic foot
*Material densities are provided for estimation only. Actual material densities may vary.

SAFETY INSTRUCTIONS
This machine demands skilled operation therefore, you must read this operator’s manual
before connecting the machine to the tractor. Even though you may have owned or operated
similar equipment, you should read through the safety and maintenance procedures
thoroughly. This concerns your safety.
The Bauman Drop Spreader should only be operated by one person. The operator should
ensure that no one is close to the area where the machine is in use. Do not let others operate
the machine unless you are certain that they have the necessary knowledge to operate the
machine safely and correctly.
The following precautions should be read and understood before operation of the machine:
▪Activate the tractor’s parking brake and stop the tractor’s engine before:
•Unclogging material jams;
•Lubricating the machine;
•Cleaning the machine;
•Disassembling any part of the machine;
•Adjusting, repairing, or maintaining the machine.
▪Lower the machine to the ground when parked.
▪Disconnect power before servicing.
▪Do not work underneath an elevated unit until it has been secured mechanically or with
stop wedges.
▪Do not start or operate the tractor until bystanders are clear of the machine.
▪Check to make sure that all tools have been removed from the machine before starting
the tractor.
▪Check that all safety shields and grills are in place and secured.
▪Do not operate the machine while wearing loose garments.
▪Use statutory vehicle lights and safety markings when operating the spreader on public
roads or when driving in the dark.
▪Hearing protection is recommended, especially if the machine is in use over a long
period of time.
▪Before lifting or lowering the spreader, ensure there is no one in the vicinity of the
machine. Do not stand between the tractor and the spreader during attachment and
detachment.
▪The machine has been manufactured strictly for the intended use as a drop spreader.
Do not use the machine for any other purpose.
▪Be considerate of people, property and animals near the machine. Maintain a distance
of at least 10 meters from obstacles while operating from the machine.

5
▪Use only original components or replacement components received from Bauman
Manufacturing.
▪Sitting, reaching into or climbing on or in the spreader during operation can result in
serious injury or death. Do not ride on the spreader while the vehicle is in motion.
▪All laws and rules relating to public safety in the country of operation must be obeyed.
Follow both the vehicle and spreader manuals to ensure safety and mechanical
efficiency.
It is the operator’s responsibility to ensure the safety of themselves and others
while operating or maintaining a Bauman Drop Spreader.
SAFETY LABELS
The danger labels on Bauman Manufacturing equipment are for the safety of the operator as
well as pedestrians and bystanders. Read and obey warning and danger labels. The operator
must ensure that before operating the machine, all guards and grills are in place and that they
are attached properly. Stay clear of all moving parts and rotating shafts.
Under no circumstances should anyone reach into the
hopper when the spreader is in operation.

6
MAINTENANCE
Warning: When repairing, maintaining and cleaning the machine, it is particularly important
to be aware of the safety precautions. Park the tractor (if connected) as a precautionary
measure and disconnect power when servicing. Do not clean, lubricate or adjust the machine
before the tractor engine has been stopped and the parking brake is activated.
Important: Screws and bolts on your new machine must be tightened up after the first two
hours of operation. All moveable parts must be greased regularly for the best performance.
To extend the durability of the machine, frequent and thorough cleaning is recommended. Set
spring tension to loosest setting for ease of cleaning the machine and use plenty of water
when cleaning to avoid material freezing on the roller or rubber belts.
Remember: Do not spray water directly into bearings or bearing housings. If the machine is
stored for a lengthy period of time, spray it with acid-free oil before use. Remove all foreign
material from the roller. Check and lubricate all chain and bearings regularly.
It is important to properly maintain and service your spreader. Failure to comply
with the manufacturer’s suggested servicing procedures may result in premature
wear and may hinder the machine’s performance.
ATTACHMENT OF THE MACHINE
This spreader can be attached to the tractor using various methods. It is the operator’s
responsibility to make sure that it is connected and fastened properly and safely. Ensure that
the spreader sits horizontally when in operation.
Hydraulic Units: Ensure the hydraulic hoses are properly connected to the tractor’s hydraulic
ports. Improper connection may damage the machine if the oil runs in the wrong direction.
Flow control and hoses to the motor are included.
PTO Units: Attach PTO shaft to the tractor. Make sure that the PTO yoke push pin is engaged
properly. Ensure the PTO shaft is cut to the proper length so there is no tension on the
gearbox when the spreader is raised. PTO shaft is included.

SPREADING MATERIAL
REGULATING SPREAD QUANTITY
The spreading quantity is adjusted with the tension adjustment lever. Correct adjustment is
important. If the adjustment is too tight, unnecessary wear of the rubber belts or rotating parts may
occur. If the adjustment is too slack, distribution of material will be uneven.
Hydraulic Units: All hydraulic units are equipped with hydraulic flow control. To ensure to correct
rate of drop of material, the operator would adjust the tension adjustment lever, hydraulic flow
control, engine RPM, and ground speed. Adjusting engine RPM impacts hydraulic flow.
PTO Units: To ensure the correct rate of drop of material, the operator would adjust the tension
adjustment lever, engine RPM, and ground speed.
STARTING TO SPREAD
Spreading of material starts as soon as the tractor’s PTO, hydraulic, or electrical system is engaged.
HYDRAULIC ROUTING INSTRUCTIONS
Hydraulic: The hydraulic spreader models come equipped with the hoses and fittings already
installed in their intended orientation. Ensure the tractor hoses are attached in such a way that
allows for the agitator and distributor drum to rotate in the direction shown in Figure A. A decal
depicting the correct rotation direction has also been positioned near the bearings supporting these
shafts.
