Operation
Preparation for Use
Before putting the spreader into operation make sure
the machine has been properly adjusted and the spread
pattern has been determined.
IMPORTANT: Read and thoroughly understand the
contents of the operator’s manual before
operating.
• Visually inspect the spreader for damage or missing
parts. Contact your Loftness dealer if any parts need
replacing.
• Check the v-belts and chains for tension and
alignment.
• Check the machine for loose bolts. Check bearing,
sheave, and sprocket set screws.
• For PTO drive models, check the rear belt wrap. The
spinners should rotate in opposite directions.
• Check wheel lugs for tightness.
• Check tire pressure.
• Turn conveyor chain by hand to ensure it moves
freely without obstruction(s).
• Check conveyor chain for tension. There should be a
2-3 in. (5.08 - 7.62 cm) sag underneath.
• Perform a test pattern.
IMPORTANT: Before placing the fertilizer spreader into
operation, a spread pattern test MUST
be performed. Refer to “Spread Pattern
Test” on page 14 for instructions.
Connecting to Tractor
For PTO Drive Models
Adjust the spreader hitch so the spreader is as level as
possible. Connect to the tractor and install an approved
hitch pin for the load, securing hitch pin with a safety
locking pin. Connect the safety chains to the tractor.

Connecting to Truck (Transporting)
CAUTION: Tow only with a truck or vehicle
capable of pulling the weight of the spreader
and its contents.
Adjust the spreader hitch so the spreader is as level
as possible. Connect to the truck hitch and install an
approved hitch pin for the load, securing hitch pin with
a safety locking pin. Connect the safety chains to the
truck. Connect surge breakaway chain to the truck
Connect the spreader’s running light wiring harness to
the truck.
IMPORTANT: Make sure PTO is locked in the storage
cradle and hydraulic hoses are secure
before transport.
Setting the Metering Gate Opening
The application rate is determined by the metering gate
opening and the speed of the conveyor chain.
To determine the gate opening:
1. Determine the fertilizer density. Weigh 1 gallon (3.78
Liters) of the fertilizer and then multiply that by 7.5.
2. Select the column with the value closest to your
outcome in the “Product Density” row of the
application rate chart found on page 13. Follow
this column down to the desired application rate.
3. Follow this row to the left of the chart to the proper
gate opening size.

3
Loosen knob (1). Move the gate control lever (2) until
the indicator (3) is at the proper setting. Lock gate by
retightening the knob (1).
Operation

11Fertilizer Spreader OM
Adjusting for High or Low Range
1
Determine if the application will be spread in high range
or low range.
High range - the chain must be on the inside sprockets.
Low range - the chain must be on the outside sprockets.
If adjustment is needed, loosen the conveyor drive chain
tensioner (1) and move the chain to the appropriate set
of sprockets. Reposition the drive chain tensioner and
retighten. Chain tensioner should be oriented such that it
does not touch sprockets.
IMPORTANT: Read the application rate chart for
operating in high range. To avoid undue
stress on the conveyor mechanism, it is
recommended to use the largest practical
gate opening in low range before
changing to high range.
To assure a uniform application rate around field edges,
make a border application with these adjustments.
Reduce to 1/2 fan speed, gate opening, and travel
interval.
CAUTION: Do not use a gate setting of
1.5 in. (3.81 cm) in high range. This could
cause undue stress on the hopper from a high
conveyor speed.
Operation
Engaging the Conveyor Ground Drive
1
2
Raise the lever (1) to the upper position as shown to
engage the ground drive. Secure with retaining pin (2).
To disengage the drive, move the lever to the lower
position and secure with the retaining pin.
During transport, always have the ground drive
disengaged.
IMPORTANT: Be sure the chain engages the hub
sprocket properly. If it slips to one
side, raise the chain and realign before
lowering.

12 Fertilizer Spreader OM
Spreading Speed and Interval
Speed
When spreading for a test pattern and for the final field
application, maintain a speed of 3-8 mph.
Driving Interval
Test Pattern Interval: Driving interval is 50 ft. (15.24 m)
to maintain accurate application rate and spread pattern.
Field Application Interval: Determine optimum driving
interval by following the steps below.
NOTE: The spreader is designed to spread the material
50 ft. (15.24 m) to each side of center, giving a
double coverage for a uniform application. The
application chart is based on 50 ft. (15.24 m)
driving intervals, not the actual spread width.
However, a slight change in driving distance may
be beneficial for optimum coverage.
1. Make sure all adjustments and a spread pattern has
been produced following the “Spread Pattern Test”
and “Spread Pattern Adjustments” section in this
manual.
2. From the Spread Pattern Test Results Sheet found
on page 16, determine the maximum (cc) volume
value of material in center of pattern.
3. Divide this value by two.
4. Locate the distance from the zero foot mark
(centerline of driving path) where the graph intersects
this (cc) value.
5. Multiply this distance by two to determine the
optimum driving interval.
Even if the pattern has an acceptable shape, optimum
driving interval may be too small for practical field
use. If this is the case, the spreader must be adjusted
to produce the best possible pattern shape with an
acceptable driving interval.
CAUTION: Do not exceed the rated gross
weight of the spreader.
Operation
