traction from vehicle allows more ground engagement and the lighter the

MAINTENANCE & STORAGE

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 / RECOMMENDED 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.

The grader can be pulled by various style vehicles but a 500 cc ATV/UTV or a 20 HP /500 lb.
garden tractor is recommended. 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
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.

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.

TRANSMITTER 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) Ensure that the wiring harness is connected at all
points: battery, switch, actuator, and receiver.

2) Press and hold one of the buttons on the wireless
handheld remote. While holding the one button

3) The wireless system is now activated and operational

4) Press the IN and OUT button as needed.

To turn off the wireless system press both buttons on the

wireless transmitter simultaneously and hold them
down for 3 seconds until the RED light turns off on
both the transmitter and receiver.

SWISHER HISTORY

Back before electricity came to rural Missouri Max Swisher was producing lawn mowers
fr

om 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
Mechanics Magazine and others. In January 2000 Popular Mechanics Magazine
named Max’s zero turning radius riding mower one of the 20thcentury’s top household
inventions.

Swisher offers value and function in its products to meet your grounds maintenance
needs.
