SAFETY PRECAUTIONS

TOWING SAFETY

When storing the grader always lower the grader to which the scarifiers contact the ground and the
actuator is relieved of carrying any load. It is not recommended to ever leave the grader stored with
the actuator holding the weight of the unit.
It is recommended to use the jackstand provided to raise and lower the unit when connecting and
disconnecting from vehicles. DO NOT try and lift the weight of the grader by yourself when
uncoupling, it may cause injury.
INTENDED USE / RECO ENDED VEHICLES
The grader is intended to refinish non-public driveways or roadways consisting of primarily
gravel and or rock. Be aware of your surroundings and what is beneath the ground you
intend to use the grader on. ALWAYS avoid large rocks, embedded obstacles, and buried
utilities such as gas, electric, or phone lines.
A minimum of a 500 cc ATV/UTV or a 20 HP /500 lb. garden tractor is required to pull the
grader and Four-wheel or all wheel drive is always recommended when available on the
vehicle to gain maximum traction to ensure best performance.
Understand that the amount of ground engagement with the scarifiers depends strongly on
the type of vehicle you are using and media make up that you are refinishing. The looser the
media and the more
traction from vehicle allows more ground engagement and the lighter the
vehicle and more hard packed the media allows less engagement.
It is recommended to start with minimum engagement (1/4”-1/2”) when beginning to refinish
an area, and as the ground loosens increase the depth of engagement on scarifiers.
The grader design allows the operator to add weight to the unit if necessary to break up the
ground when pulled with an adequate vehicle. The weight area is located in the main frame
section on the unit on either side of the actuator mount. Any additional weight should not
exceed 100 lbs and should always be secured within the weight area by any means possible.
MAINTENANCE & STORAGE
Fig. 1
Fig. 2
The rear blade on the grader can be
used in several positions depending
on the work you are doing.
In fig. 1 the blade is free floating and
only restrained by the a pin in the last
pin position. This allows the blade to
swing freely and the weight of the
blade helps level and smooth loose
media. In fig 2 the blade is pinned in
the upright position and the grader
can act as a scrapping blade when
scarifiers are raised up away from
media.

쫀Ӝ
TRANS ITTER AND RECEIVER
The grader comes equipped with a remote control to raise and lower
the unit by electric actuator. The remote has two buttons, one to
extend and one to retract the actuator. Follow the directions
below to activate the remote once battery is installed.
1) Once receiver is plugged into a power source, with the
remote in hand hold down the button on the receiver box
until a GREEN LED light comes on solid.
2) Once the GREEN LED is solid hold down one of the buttons
on the remote for approximately one second and verify the
GREEN LED light flashes momentarily when button is
pressed.
3) Repeat this process but with the opposite button on the
remote
4) Once both signals have been sent to the receiver the LED
light on the receiver should turn solid RED. This means
your transmitter and receiver are now paired.
5) Press the IN and OUT button as needed.
To turn off the wireless system press the button on the receiver box
once and ensure there is no longer a LED light on.
LED Indicator Light
Steady RED – The system is active and ready to use.
Flashing RED during use – The battery or power source is low.
RED light is off – The wireless remote control is turned off, or not
active.
Replacing batteries
If the indicator light on the handheld remote
flashes during use, the batteries are
low and should be replaced.
1) Remove the two screws from the
handheld remote located on the back
of the remote.
2) Separate the top and bottom sections
of the remote using a flat head screw
driver or similar device.
3) Remove the old batteries and dispose
in accordance with local
environmental regulations.
4) Insert (2) new A23 style alkaline
batteries as shown with the positive
terminals facing the switches. Do not
mix old and new batteries.
5) Join the top and bottom sections
making sure they snap together and
rubber seal remains intact.
6) Secure with the two screws.

Supplying Power to the Grader
The grader is supplied with two power leads. The remote power lead (20038) is
designed to be attached to your AT /UT or other vehicles 12 battery. The onboard
power lead (20039) is designed to hook up to a battery installed directly on the grader.
Both power leads plug directly into the grader wiring harness but only one can be used
at a time. The 20039 harness requires (2) NB524 nuts and (2) NB690 bolts to fasten to
battery posts. These are located in the parts bag.
Caution: Always be sure to install RED wire of lead to Positive side of battery
and BLACK wire of lead to the negative side of battery. ALWAYS disconnect
negative (black) lead from battery first and install negative (black) last when
reconnecting to battery.
Caution: Always be sure to secure the remote lead to tongue of grader and vehicle
so not to drag on ground or become tangled in unit.
*Below is a visual of all harnesses and where the connections attach.
NOTE: Grader does not come supplied with a battery but has the option of installing
an onboard battery. The unit is designed to use a 12 U1 or U1 deep cycle battery.
Any other style of battery may not mount on unit correctly or allow unit to function
properly.
aintaining Battery: It is very important to recharge a battery after each use or
if completely drained, and also recommended to install a battery tender (charger)
on to the battery when not in use. IT IS NOT recommended to charge a battery
at more than a 10 amp rate for extended periods of time.

SWISHER HISTORY
Back before electricity came to rural Missouri Max Swisher was producing lawn mowers
from his mother’s chicken house. Max never liked to mow grass. He installed a
gearbox on his family’s lawn mower creating a self-propelled unit. By tying one end of a
rope to the mower and the other end to a tree in the center of the yard the mower
circled the tree, shortening the rope and guiding the mower in concentric circles. Max
enjoyed relaxing under a shade tree while his invention did all the work.
Max had designed his first self-propelled rotary lawn mower to do his dirty work for him.
Neighbors noticed his new invention and began asking him to make more. Today, 60
years later, Swisher is still producing innovative lawn and garden and ATV/UTV
equipment designed to give us all more “relaxing in the shade” time.
Swisher products have been featured nationally on television programs such as Regis
and Kathie Lee and seen in publications like ATV Magazine, Country Journal, Popular
Mechanics Magazine and others. In January 2000 Popular Mechanics Magazine
named Max’s zero turning radius riding mower one of the 20th century’s top household
inventions.
Swisher offers value and function in its products to meet your grounds maintenance
needs.
