TRACTOR SIZE REQUIREMENTS
The spreader does not have brakes. Towing the spreader
must be done safely. The ASAE (American Society of
Agricultural Engineers) specifies that the towing vehicle
should weigh at least 2/3 as much as the loaded
implement to be reasonably safe towing at speeds up to
20 mph. This (20 mph) is also the maximum
recommended towing speed for the spreader.
The loaded weight of your spreader will naturally vary with
the moisture of the manure and you must consider that for
your conditions. The loaded weight capacities as specified
by the spreader manufacturer are as follows:
Use the following chart for calculating the minimum tractor
weight.

E.g. For a struck level load of Chicken Litter:
17,400 + (530 ft
3
x 65 lbs)
17,400 + 34,450 = 51,850
51,850 x (2/3) = 34,566 lbs
Minimum Tractor Weight: 34,566 lbs
NOTICE! Heaped loads have significantly higher
capacities, resulting in increased weight and a higher
center of gravity. These loads require extra precaution
during transport and operation.
OVERVIEW
The spreader rear beaters are driven directly by the
tractor PTO.
The spreader rear end gate, hydraulic jack, and hydraulic
apron are on separate hydraulic circuits, so 3 sets of
hydraulic hoses must be connected to the tractor. The pair
of hoses for the hydraulic apron must be connected to
tractor hydraulics with adjustable flow control, (with
standard options.) A check valve in the apron motor circuit
will prevent the apron motor from running backwards. The
check valve will also prevent incorrect apron operation if
the hoses are accidentally reversed at the tractor.
When unloading is complete, the tractor control operating
the apron must be shut off. Once the apron has been
stopped, the tractor control operating the end gate is
reversed to lower the gate.
HYDRAULIC SYSTEM
This standard spreader hydraulic system does not include
an onboard flow control to regulate the apron speed.
Instead, the tractor must have adjustable flow control
(turtle/rabbit icons) to regulate the spreader apron speed.
The spreader is equipped with a flow control valve, which
will regulate flow to the apron motor. The hydraulic motor
used to power the apron has a built-in pressure relief to
prevent accidental damage to the gearbox and apron.
WARNING
ESCAPING HYDRAULIC FLUID UNDER PRESSURE
CAN PENETRATE THE SKIN AND CAUSE SERIOUS
INJURY. RELIEVE ALL PRESSURE FROM THE
HYDRAULIC SYSTEM BEFORE CONNECTING OR
DISCONNECTING THE LINES OR MAKING REPAIRS.
CHECK ALL HOSES AND FITTINGS BEFORE
STARTUP AND PERIODICALLY DURING OPERATION.
