ASSEMBLY INSTRUCTIONS

Your MIGHTY MAC tiller has been shipped to you almost completely assembled, leaving only
the handles and control rods to install. Before beginning assembly, make sure all parts have been
received and are in good condition. If there are shortages or damage, notify the company from whom
you bought the machine, and the delivery agent at once.

(Note: In the following instructions, the "item" number refers to the number encircled for that part
in the illustrations).

1) Release the shipping straps holding your tiller to the skid.

2) The handles and swivel assembly (item

19,

the tiller for shipment. Remove the shipping bolt asshown in figure 1.

4) Position the handle height adjusting bolts asshown in Fig. 3. Use the shipping bolt and nut from
(2), above, and the matching bolt and nut from the small bag attached to the engine. We would

suggest you set the handles a little higher than a comfortable height to compensate for them
dropping a few inches when the Tines are in soil.

5) Install the Clutch Rod Swivel, (item 49, fig. 2) through the hole provided in the clutch lever plate

(item 44, fig. 2).

6) Insert the wheel engagement rod assembly, item 32, in the wheel engagement lever as shown in

fig. 14 using the

1/8/1x1/1

cotter pin from the small bag.

OPERATING INSTRUCTIONS

Your Mighty Mac 824 RT tiller has been designed to be the smoothest operating tiller possible. It is

very easily controlled but, as with any machine, requires that you

familiarize

yourself with its features

-and

follow a few important rules to get the most from it.

To operate your tiller SAFELY, there are several cardinal rules you must follow:

1) NEVER ATTEMPT

TO TILL WITH THE WHEELS DISENGAGED.

2) NEVER START

THE ENGINE WITH THE CLUTCH ROD (item

46, fig. 12)

ENGAGED IN

FORWARD OR REVERSE DRIVE.

3)

NEVER PUSH DOWN ON THE HANDLES HARD ENOUGH TO RAISE THE WHEELS
OFF THE GROUND.

To understand the importance of these rules, you should understand that the wheels are not intended

to pull the machine along; rather, they are there to hold back

against

the tines pushing the tiller forward.

For this reason, the wheels must be engaged and on the ground at all times; otherwise, the tines will

push it along too fast and the

tiller

will be out of control. Obviously, this creates a potentially

dangerous situation.

We have madeitpossible to

disengage

the wheels to make it easier to move the

tiller

about

with

the
engine "off". This is particularly useful in maneuvering the tiller in confined areas such as your garage
or tool shed or in moving it to and from your garden.

You may feel that the

tires

are installed backwards from the conventional way

tires

of this type

-are used. They are, however, correct as shown, because

oftheir function

To start your

tiller

and get under way, first make sure the engine crankcase and tiller transmission
