Slope Operation
Use Extreme caution when operating and/or
turning on slopes as loss of traction and/or tip-over
could occur. The operator is responsible for safe
operation on slopes.
See the inside of the back cover to determine the
approximate slope angle of the area to be
operated on.
Remove or mark obstacles such as rocks, tree
limbs, etc. from the area. Tall grass can hide
obstacles.
Watch for ditches, holes, rocks, dips, and rises
that change the operating angle, as rough terrain
could overturn the machine.
Always avoid sudden starting or stopping on a
slope. If tires lose traction, turn off aerator and
proceed slowly off the slope.
Operating on wet grass or steep slopes can
cause sliding and loss of control. Wheels
dropping over edges, ditches, steep banks, or
water can cause rollovers, which may result in
serious injury, death, or drowning.
Do Not operate on slopes when grass is
wet.
Do Not operate on slopes greater than 15
degrees.
Do Not operate near drop-offs or near
water.

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.

Operation
Note: The left and right sides of the machine are
defined as standing behind it and facing the
direction of operation.
Pre-Start
Fill fuel tank, for best results use clean, fresh
regular unleaded gasoline with an octane rating of
87 or higher.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Never fill fuel tank so
that the fuel level rises above a level that is ½ inch
(13 mm) below the bottom of the filler to allow for
fuel expansion and prevent fuel spillage.
Make sure the operator understands the controls,
their locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all
necessary inspection and maintenance steps.
Operating Instructions
Hitching Machine and Set-up
The UA-60T can be hitched to any working vehicle
desired for operation. The standard 2 inch ball
coupler is utilized for most applications. The
optional draw-bar attachment can be used in
situations where the 2” ball coupler is not feasible,
such as small utility tractors.
Once the machine is connected, the hand-held
control switch must be installed. Located under the
fuel tank, a socket receives the plug from the
control switch. Uncoil the switch and use ties as
necessary to ensure the cord does not make contact
with the vehicle in turns or the ground upon
lowering to the ground.
Leveling Aera-vator for Operation
The UA-60T is equipped with a top link connected
to the sway bar on the right side. This top link is
adjusted in or out to level the aerator during
operation.
1. With the machine hitched at the worksite, start
the engine.
2. Lift the Auto Throttle Handle to disengage the
throttle, Figure 8, and use the control box to
lower the machine to the ground.
3. Rotate the top link as necessary to level the
machine, Figure 9.
4. Raise the machine and engage the Auto Throttle
Handle for use.
Start the Engine
1. Before starting the engine, if the machine is in
the lowered position. The Auto Throttle
Handle, Figure 8, must be lifted to disengage
the throttle.
2. On a cold engine, pull the choke knob outward
into the “ON” position.
3. On a warm engine, leave the choke in the
“OFF” position.
4. Turn ignition switch to the “START” position.
Release the switch as soon as the engine starts.
IMPORTANT: Do NOT crank the engine
continuously for more than ten seconds at a
time. If the engine does not start, allow 60
second cool-down period between starting
attempts. Failure to follow these guidelines
can burn out the starter motor.
5. If the engine is difficult to start, the throttle can
be used momentarily. As soon as the engine
starts, cut the throttle down to the idle position.
6. If the choke is in the “ON” position, gradually
return choke to the “OFF” position as the engine
warms up.

Aeration
With the engine running and the machine fully
lifted:
1. Ensure the Auto Throttle Handle is lowered
back into position to allow the throttle cable to
be pulled when machine is lowered to ground.
2. Tow machine to starting point on worksite and
lower using hand-held control switch, Figure 3.
3. Adjust the ground speed accordingly. Slow
down to allow tines to penetrate deeper. The
chain hanging on the left side of the machine is
a visual indicator for depth. If the chain is
touching the turf, full depth is achieved.
4. Press the control switch to lift the machine when
desired.
Operating the Attachments
The UA-60T is equipped to have both a solid roller
and a brush fastened to the frame. Attachments can
be seen in further detail in the parts list portion of
this manual.
The roller is seen is Figure 10. It is made to
primarily float using a slot located on the top
bracket on the frame. When down pressure from
the roller is desired, the top link is adjusted to lower
the roller downward until down pressure is achieved
and the pin is at the top of the slot.
The brush is shown in Figure 11. It is fastened to
the frame in a three-point hitch configuration to
allow smooth floatation. The brush easily locks
into place for transportation by simply lifting the
brush to the top of its range. The brush can be
modified to various widths and configurations to
conform to the user’s needs.
The movement of the rotors on the machine is
dangerous. Contact with rotor shaft can
cause serious injury or death. Do NOT put
hands or feet in the working area of the rotor
shaft while activated.

Offsetting unit
The unit may be operated either directly behind the
tow vehicle or offset to the side of the vehicle. The
unit can be offset by changing the tongue position,
Figure 12. The offset can be adjusted between the
two outer positions shown by aligning the holes in
the tongue with either of the sets of holes in the
Tongue Swivel.
Transporting unit
Before transporting the UA-60T from one location
to another, the red handled Cylinder Lock-Bar
located by the lift cylinder must be pinned to the
cylinder to prevent the machine from gradually
leaking down over time. The red handled Cylinder
lock-bar is seen in Figure 13.
The tongue of the unit should also be locked to its
centered position, Figure 12, with the stop bolt
being tightened against the tongue and locked into
place with the jam nut, Figure 14. The unit should
only be transported while centered behind the
tow vehicle with the stop bolt tightened.

gaps, or replace with new plugs. See Engine
Owner’s Manual.
Check Fuel Filter
Service Interval: As required
A fuel filter is installed between the tank and the
engine. Replace when necessary.
Change Hydraulic System Filter
Service Interval: After the first 250 hours,
Yearly thereafter
1. Stop engine, wait for all moving parts to stop,
and remove key.
2. With the lift cylinder fully retracted, use the red
handled lock-out bar to pin the cylinder into
place and prevent the machine from leaking
down.
3. Carefully clean area around filter. It is
important that no dirt or contamination enters
the hydraulic system.
4. Use proper tools to slowly remove the hose and
fittings from the in-line filter. Pay special
attention to the direction the filter is oriented.
5. Install new filter using proper tools and torque
on adapters and fittings.
6. Operate machine for several minutes
7. Check oil level.
Note: Do Not change hydraulic system’s oil
(except for what can be drained when changing
filter), unless it is required due to contamination or
overheating. Changing oil unnecessarily could
contaminate hydraulic system.
Failure to lock out the lift cylinder while
performing maintenance on the hydraulic
system can result in serious injury.
Hydraulics fluids escaping under pressure
can penetrate skin and cause injury.
Keep your body and hands away from
pin hole leaks.
Hydraulics Couplers, hydraulic lines/valves,
and hydraulic fluids may be hot. If you
contact hot components you may be burned.
Wear gloves when operating the
hydraulic couplers.
