ASSEMBLY INSTRUCTIONS  
-Note-  
5. Mount the sulky frame on the hitch ball and  
secure in place by pushing down the locking  
lever on the coupler.  
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.  
-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.  
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.  
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.  
-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.  
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  
balljoints.  
3. Mount the hitch ball onto the hitch bracket  
using the 3/4" lock washer and the 3/4"-16  
hex nut.  
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.  
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.  
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.  
-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.

Figure 1  
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)  
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.  
15. Screw the remaining LH and RH threaded  
1/2-20 jam nuts onto the remaining two ball  
joints.  
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  
2" bolt and a 1/2-13 elastic stop nut.

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.  
16. On the steering tie rod, adjust the ball joints  
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)  
23. Attach the arm rests to the seat back and use  
set screws to adjust arm rests until they are  
horizontal.  
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.  
-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.  
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.  
24. The two sulky wheels should have a 1/16"  
toe-in adjustment. To make this adjustment,  
adjust the two wheel tie rods.  
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.  
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.  
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 7/16-  
14 elastic stop nuts.  
-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-  
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.  
-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.
