INTRODUCTION

This manual has been prepared to provide the
information you need to correctly assemble,
operate and maintain this attachment. Read it
carefully and keep it for future reference. Should
you ever need repair parts or service, contact your
authorized Scag Service Dealer.

Any reference made in this manual concerning the
RH or LH sides are determined with the operator
in the normal operating position.

manual that is supplied with the machine this
attachment is used on. A replacement manual
is available by sending complete model and
serial number to:

Scag Power Equipment

1000 Metalcraft Dr.

P.O. Box 152

2. Do not operate this sulky on steep slopes.

The replacement of any part on this product by
other than the manufacturer's authorized
replacement part may adversely affect the
performance, durability or safety of this product.

SAFETY AND OPERATING
INSTRUCTIONS

To avoid personal injury, it is imperative that all
safety instructions be observed.

Your sulky was built to the highest standards in the
industry. However, the use of a riding sulky, when
attached to a walk behind mower, is only as safe
as the operator. Carelessness or error on the part
of the operator may result in serious bodily injury.
Please read and follow these instructions on safe
operation, and be certain anyone using this sulky is
familiar with these rules.

3. Do not run over rocks, holes or other
obstructions that may make the sulky
unstable.

4. Always keep both hands on the steering
controls when using the mower with the sulky
attached.

5. When operating the mower in reverse, make
certain that there are no obstructions behind
you.

6. Have a first time operator practice driving the
mower and sulky in an open, level area before
operating under actual mowing conditions.

7. Before leaving the sulky seat:

l Disengage blade clutch
l Engage both neutral locks
l Pull speed control lever to neutral
l Apply the parking brake
l Wait for all movement to stop

ASSEMBLY INSTRUCTIONS

-Note-

Before assembling and connecting this
accessory to your machine, turn the engine
off, remove the key, and remove the spark
plug wire from the engine.

1. Remove all crating and packing materials.
Lay out the mounting hardware according to
the “where used” list on page 5.

2. Bolt the hitch bracket onto the rear of the
engine deck using (3) three 3/8-16 x 1-1/4"
bolts and (3) three 3/8-16 elastic stop nuts.
The bolts must be installed from the inside
facing out.

-Note-

If you are mounting the hitch bracket to an
older machine with only two holes on
the rear of the engine deck, you may use the
hitch bracket to locate the third hole.
Bolt the hitch bracket to the existing two
holes and mark the third hole using a
center punch. Unbolt the hitch bracket and
drill a 13/32" hole at the mark for the
third hole. You are now ready to mount the
hitch bracket.

3. Mount the hitch ball onto the hitch bracket
using the 3/4" lock washer and the 3/4"-16
hex nut.

4. Mount the wheel assemblies onto the wheel
spindles. Place the 1" wheel spacers onto the
wheel spindles, and install the "E" clip on to
each of the wheel spindles.

-Note-

There will be more wheel spacers in the
hardware package than you will use. Install
the appropriate sized wheel spacers onto the

wheel spindle to remove the back and forth
movement of the wheel assemblies with the
“E” clip installed.

5. Mount the sulky frame on the hitch ball and
secure in place by pushing down the locking
lever on the coupler.

-Note-

When performing steps 5 through 8 keep in

mind that the (3) three tie rods will have
one end that has RH threads and one end
that has LH threads.

Included in the hardware package are:

l (3) three LH threaded 1/2 x 1/2-20

ball joints.

l (3) three LH threaded 1/2-20 jam

nuts.

l (2) two RH threaded 1/2 x 1/2-20

ball joints.

l (1) one RH threaded 5/8 x 1/2-20

ball joint.

l (3) three RH threaded 1/2-20 jam

nuts.

6. Screw (2) two LH threaded 1/2-20 jam nuts
onto (2) two LH threaded 1/2 x 1/2-20 ball

joints.

7. Screw (2) two RH threaded 1/2-20 jam nuts
onto the (2) two RH threaded 1/2 x 1/2-20
ball joints.

8. There are three tie rods included in the sulky
assembly. The two shorter ones are the
wheel tie rods and the longer one is the
steering tie rod.

9. Screw the (2) two LH 1/2 x 1/2-20 ball
joints with jam nuts into the LH threaded
ends of the wheel tie rods. Screw the RH
1/2 x 1/2-20 ball joints with jam nuts into the
other wheel tie rod ends.

Figure 1

10. On the (2) two wheel tie rods, adjust the ball
joints on the tie rods so that you will get
12- 7/8” distance between the center of the
holes on the ball joints. (See figure1)

11. Tighten the (4) four jam nuts on the ball
joints against the tie rod ends to prevent
turning of the ball joints on the tie rods.

13. Bolt one end of the other wheel tie rod
below the lever on the right wheel spindle.
Place a 1/2" ball joint spacer between the ball
joint and wheel spindle lever. Secure using a
1/2-13 x 2" bolt and a 1/2-13 elastic stop
nut. (See figure 2)

14. Place the other end of the tie rod coming
from the left wheel above the larger lever of
the steering bellcrank located in the center of
the sulky frame. Place the other end of the
tie rod coming from the right wheel below
the larger lever of the steering bellcrank.
Place (2) two 1/2" ball joint spacers between
the (2) two ball joints and the steering
bellcrank lever. Secure using a 1/2-13 x 3
1/4" bolt and a 1/2-13 elastic stop nut. (See
figure 2)

12. Bolt one end of a wheel tie rod above the
lever on the left wheel spindle. Place a 1/2"
ball joint spacer between the ball joint and
wheel spindle lever. Secure using a 1/2-13 x

on the tie rod so that you will get 32-1/2”
distance between the center to center holes
on the ball joints. (See figure 3)

17. Tighten the jam nuts on the ball joints
against the tie rod ends to prevent turning of
the ball joints on the tie rods.

18. Connect the 1/2 x 1/2-20 end of the steering
tie rod to the small lever on the steering
bellcrank. Place a 1/2" spacer between the
ball joint and steering lever and secure using
a 1/2-13 x 2" bolt and a 1/2-13 elastic stop
nut.

19. Mount the 5/8 x 1/2-20 end of the tie rod to
the pin on the hitch bracket and secure with
the small quick pin.

20. Mount the seat spring and reinforcement seat
spring above the sulky frame and mount the
lower support plate below the sulky frame.
Secure using the (2) two 7/16-14 x 4" bolts,
(2) two 7/16" flat washer and (2) two 7/16­14 elastic stop nuts.

-Note-

There are extra bolt holes to choose from
when mounting the seat spring to the sulky
frame and mounting the seat and seat plate
to the seat spring. Choose the ones that
will provide the most comfort for the
individual users.

21. Mount the seat onto the seat plate. Place the
(4) four 3/8" flat washers between the seat
and plate. Secure using (4) four 5/16-18 x 3/
4" bolts and (4) four 5/16" lock washers.

22. Mount the seat and seat plate to the seat
spring using (2) two 3/8-16 x 1" bolts and
(2) two 3/8" lock washers.

23. Attach the arm rests to the seat back and use
set screws to adjust arm rests until they are
horizontal.

-Note-

A final adjustment may be required on the
tie rods for the sulky wheels to be aligned
straight with the SWZ machine and to have
proper toe-in adjustment. To adjust the tie
rods, loosen the two jam nuts and turn the
tie rod tube to lengthen or shorten the tie
rod. Retighten jam nuts.

24. The two sulky wheels should have a 1/16"
toe-in adjustment. To make this adjustment,
adjust the two wheel tie rods.

25. Start the engine and drive the mower with
the sulky attached. If the sulky does not
track straight behind the mower, you must
adjust the streeing rod so that the wheels are
even with the mower.

-Note-

For operator comfort the handles on the
SWZ should be raised to the highest
position. Refer to the SWZ's technical
manual for this adjustment.

-Note-
To move the sulky when not attached to the
mower, you must lock the wheels in a
forward position. The wheels can be
locked in the forward position by inserting
the ring pin through the holes in the sulky
frame and the steering bellcrank.
