GENERAL INFORMATION
2004 is the first year for the ZT. There are two models
ZT17 and ZT22. New for the ‘05 model year is a Kohler
Command 19 HP model with a 50” cutting deck.
This series of riders has the unique feature of not hav-
ing to reset the PTO switch if the end user tries to mow
in reverse. Once one lapbar is moved in to neutral or
forward the PTO will turn back on.
The “ZT 17” has a 17 HP Briggs & Stratton Intek which
is a single cylinder engine with full pressure lubrication.
The engine drives the dual Hydro-gear Hydrostatic
transmissions and the electric PTO. The PTO runs the
3-in-1blades on the 42” twin blade stamped deck. On
the front of the stamped frame is a large pivoting front
axle.
The “ZT 22” is very similar to the ZT 17 except for the
twin cylinder, 22 HP Briggs & Stratton Intek. There are
also 4 wheels, instead of 2, on the 50” triple blade
stamped deck.
1. DECK LEVELING
1.1. To adjust the deck pitch, front to back, loosen or
tighten the jam nuts located on the front stabi-
lizer bracket using a 15/16” socket and a 15/16”
wrench. The correct deck pitch should be 1/8” to
1/4” lower in the front than in the back, as mea-
sured from the blade tips. See Figure 1.1.
1.2. To level the deck, side to side, loosen the screw
on the left side adjustment gear using a 1/2”
socket. Using a 3/4” wrench, run the gear up or
down as necessary until each outside blade tip
is the same distance from the ground.
See Figure 1.2.

10. STEERING LINKAGE: ADJUSTMENT
10.1. Begin to adjust the steering by confirming that
both hydros are correctly adjusted for neutral
control. See Figure 10.1.
10.2. Lift and safely support the rear of the mower.
10.3. Disconnect the ferrule at the hydro end of each
lap bar control rod from the neutral return
assembly on each of the hydros. The ferrules
are secured to the neutral return assemblies with
hairpin clips. See Figure 10.3.
NOTE: In the course of normal service, it is very
unusual for the neutral return assemblies to
require adjustment unless someone has previ-
ously tampered with it. It is necessary to check
the adjustment because the rest of the proce-

dure counts on the neutral control being cor-
rectly adjusted.
10.4. Start the engine. With the control rods discon-
nected, the hydro should self-center to neutral.
The wheels should not rotate. If either wheel
rotates, the neutral return assembly on the hydro
that drives that wheel needs to be adjusted.
10.5. To adjust the neutral return assembly, loosen
the socket head cap screw that holds the center-
ing bracket in position on the housing using a
1/4” allen wrench. See Figure 10.5.
10.6. Rotate the assembly in whichever direction
causes the wheels to stop rotating. The point
where the wheels do not rotate with the engine
at full throttle is true neutral. Tighten the socket
head cap screw at true neutral. When making
this adjustment, the transmission should be
warm.
Figure 10.5
Socket Head Cap Screw
10.7. Align the post on the ferrule with the hole that it
seats into on the neutral return assembly.
Thread the ferrule up or down the length of the
control rod to center the lap bar in the neutral
recess in the control console. See Figure 10.7.
10.8. When each ferrule is in the correct position,
secure it to the neutral control assembly with a
hairpin clip.
10.9. Lower the machine to the ground. Test the oper-
ation of the hydros in a safe space.
10.10.Adjust the stop bolts so that it tracks as straight
as possible with both lap bars pushed to the full
forward position. See Figure 10.10.

10.11.The socket head cap screws that secure the
neutral return assemblies to the hydros act as a
travel stop at the hydro end of the linkage. The
lap bar pivot brackets should contact the stop
screws before the socket head cap screw con-
tacts the end of the slot on the neutral bracket.
See Figure 10.11.
10.12.If the lap bars are not aligned with each-other,
they may be adjusted using the slotted mounting
where they connect to the lap bar pivot brackets.
See Figure 10.12
10.13.After final adjustment, test the operation of the
reverse safety switches. They should turn the
PTO clutch off whenever both lap bars are in the
reverse position.
NOTE: With one lap bar in the reverse position,
and the PTO turned on, the PTO clutch should
turn off as soon as the second lap bar crosses
the threshold from neutral into reverse. Repeat
test for each side.
NOTE: When at least one lap bar is in the neu-
tral or forward position, the PTO clutch will oper-
ate. There is not a relay to re-set by cycling the
PTO switch off and on again, as is the case with
MTD front engine residential equipment.
10.14.If the reverse safety switch adjustment is not
correct, loosen the reverse safety switch bracket
using a 3/8” wrench. Pivot the bracket and
switch to a position that results in correct opera-
tion, then tighten the bracket. See Figure 10.14.
NOTE: It is not necessary to remove either con-
trol console to reach the reversesafety switches,
but it may be necessary to temporarily discon-
nect the blue wires in order to reach the mount-
ing screws for the brackets.

sides of wheel assembly.
11.4. Remove center wheel spacer and inspect all
spacers for damage. See Figure 11.4.

11.5. Lightly grease the wheel spacers during re
assembly. Using a grease gun fill the rest of the
cavity AFTER the wheel assembly has been
mounted.
11.6. Remove both caster wheel assemblies using a
9/16” wrench. See Figure 11.6.
11.7. Inspect flange bearing on top and bottom of
pivot axle. Replace if damaged. See Figure 11.7.
NOTE: Assure proper order during reassembly.
From the top down in this order: hex head cap
screw, lock washer, flat washer, flange bearing,
pivot axle, flange bearing, flat washer, and
caster bracket.
NOTE: Be sure to use a good quality grease
during reassembly.

11.8. Using a grease gun, fill the rest of the cavity
AFTER final assembly. Filling before final
assembly will allow the flange bearings to be
pushed out.
11.9. Remove both hex cap screws securing the axle
shaft to the frame. This will be done with a 3/4”
wrench. See Figure 11.9.
NOTE: Use removable threadlocking compound
such as “Loctite 242” during reassembly.
11.10.The axle shaft may be removed and inspected
for wear.
11.11. Inspect the flange bearing on each side of the
pivot axle for wear. Replace as needed.
See Figure 11.11.
11.12.AFTER reassembly use a good quality grease to
fill the axle shaft chamber.
12. SEAT REMOVAL
12.1. Disconnect the - (negative) lead to the battery.
12.2. Flip the seat forward. Keep one hand on back of
seat to prevent seat from trying to fall back. See
Figure 12.2.
12.3. Remove both wing knobs from under seat. Keep
track of washers and spacers. See Figure 12.3.
12.4. Slide seat forward to align seat spacers with

following procedures. Removing the right and left con-
sole are very similar.
The right console has the Key Switch, PTO switch,
Neutral Switch, Three Relays, Solenoid and a 20Amp
Fuse.
The left console has the Throttle, Choke Control, Hour
Meter and Neutral Switch.

13.1. Disconnect the - (negative) lead to the battery.
13.2. Using a 1/2” wrench, remove the three screws
securing the console to the seat frame.
See Figure 13.2.
13.3. From underneath remove the four #12-16 self-

frame at the front end of the console and the
rear of the console. See Figure 13.4.
13.5. The two other screws are located under the con-
sole mounting bracket. See Figure 13.5.
NOTE: If the console mounting bracket is slot-
ted, where it is attached to the seat frame box, it
may be easier to loosen the mounting screws
from the seat frame and leave bracket mounted
to the console.
13.6. Using a 1/2” socket and box end wrench,
remove the four hex screws connecting the lap-
bar levers to the pivot bracket. See Figure 13.6.
13.7. Remove the lapbars and set them aside.
NOTE: Before loosening the hex screws, mark

13.10.The throttle cable and choke knob does not
need to be removed. The console can be flipped
up on the unit and secured safely.
NOTE: There is different throttle and choke
cable routing for the different models.
NOTE: Not all models have a choke knob.
14. BATTERY REMOVAL
The battery can be removed two different ways.
Depending on the final out come of the work that needs
to be preformed is which technique you will use.
When just replacing a battery the fuel pump needs to
be removed.
If for any reason the right side control console has to
be removed in conjunction with removal of the battery,
the fuel pump will NOT have to be removed.
NOTE: THE FOLLOWING STEPS ARE FOR

THE RIGHT SIDE CONSOLE.
14.1. Disconnect the - (negative) lead to the battery.
14.2. Disconnect the + (positive) lead to the battery.
14.3. Disconnect the battery strap from frame.
14.4. Using a 3/8” wrench remove the two screws
securing the fuel pump to the engine. The hoses
don’t need to be removed. See Figure 14.4.
NOTE: When reinstalling the battery make sure
strap is hooked under the seat box before plac-
ing battery in the unit.
