Product Overview
Before operating the UA-60T, it is necessary to
understand how the machine works and why it
functions in such manner.
The machine uses an engine to power two power
transmission components: Hydraulic pump &
Electric clutch. The hydraulic pump is used to lift
and lower the machine. The electric clutch engages
the rotor shaft and causes the tines to vibrate.
Hydraulic Circuit
When the engine is on, the pump is continuously
circulating hydraulic oil from the reservoir, to the
pump, to the valve block, and back to the reservoir.
When the operator presses the momentary switch
for the raise or lower function on the hand-held
controller (Figure 3) the fluid entering the valve
block is diverted to the cylinder causing the
machine to raise or lower. See Figures 6 and 7.
Automatic Throttle Activation
The engine throttle is tied to a cable-spring
assembly which is pulled when the lift cylinder is
extended, Figure 8. When the machine is lowered,
the cylinder extends; this action pivots the bracket
hooked to the spring and cable assembly. As the
cable is pulled, the engine speed is increased.
Likewise, when the machine is lifted, the cable is
retracted by a spring on the engine.
Aeration Mechanism
The UA-60T is designed to start aeration when the
electric clutch is turned on. With the Auto Throttle
Handle, Figure 8, position down, the engine will
automatically throttle up as it lowers to the ground.
Once the tines start to touch the ground, the electric
clutch may be engaged to start the patented
vibrating tines. To lower the machine without
throttling up the engine, simply lift the pivot catch
handle, Figure 8, and allow the stud to travel in the
slot while the machine lowers to the ground.
