2. Check that the fuel valve is fully open.
3. If battery is good and starter does not engage:
a. Check that the park brake is engaged and the
PTO switch is o.
b. Check the fuse on the wiring harness.
c. Check battery (+) and (-) wires to the engine.
d. Check the harness ground wire at the engine.
e. Check the harness power connection (purple)
at the battery terminal.
f. Check the connections of the (green) start
wire at the key switch, PTO interrupt switch,
brake interlock switch, and starter.
4. The starter may have failed. Check your engine
manual.
Moving the Mower if it won’t Start
• Open both of the hydro bypass valves by
rotating about 2 turns CCW.
• You will be able to move the mower up to a max
speed of 2mph without starting the engine
• When closing the bypass valves: DO NOT over
tighten the valves as this may damage the
pump.
Troubleshoot No-PTO Condition
1. Engine runs but PTO won’t engage.
2. Shut down machine, remove key, allow to cool,
and checking the belt and wiring going to the
clutch.
3. While the engine is o, disconnect the clutch
wire, turn on the blade switch and check for
battery power from the harness. The Blue wire
that goes to the red clutch wire is power from
the PTO switch. The black/orange strip wire
going to the black clutch wire is the ground wire
going to the relay, switch by the platform switch.
a. If no voltage, check relay, Operator Presence
Switch, and PTO switch
b. If battery voltage is coming from the harness,
check the clutch.
4. To check the clutch
a. Visually check the gap between clutch and
the armature. If the gap is excessive the
clutch is mechanically worn out of spec and
must be replaced. A worn clutch may work
when cold and not reengage once warm
and the magnetic coil increases electrical
resistance.
b. Use an ohm meter and measure the
resistance in the clutch. It should be
approximately 1.84 ohms. If the number is
much lower the coil has likely shorted out. If
the number is much higher (or innite) there is
likely a burnt or “open” coil.
Deck Lift Spring Adjustment
The ZXT is equipped with two deck-lift assist springs.
Deck lift spring tension is adjusted at the factory. If
the eort needed to raise and lower the mower deck
is not satisfactory, an adjustment to the right side
spring may be necessary.
1. Raise deck up and lock in the transport position.
2. Remove spring from the front spring
attachment.
3. Move spring into desired rear adjustment hole.
4. Reinstall spring to the front attachment.
Deck Adjustments
The mower deck can be adjusted for pitch and side-
to-side leveling. Pitch is the relationship between the
front of the deck and the rear of the deck in regards
to height of cut. In most cases, a positive pitch (front
of the deck lower than the rear of the deck) of 1
degree is the optimum setting.
These adjustments can easily be made by moving
any or all of the four deck lift brackets up and down
using a 1/2” ratchet & short extension. It is best to
use blocks to lower the deck onto to assist in the
deck adjustments.
Please note that deck pitch during operation may
dier from what is measured using the process below
due to factors such as tire pressure and operator
weight.
1. Park mower safely on a level surface and inate
tires to the correct pressure.
2. Set deck pin and lower deck to 3” height of
cut. (If using blocks place under deck prior to
lowering)
3. Align blades front to rear, measure front and
rear blade tips to grounds. Use the following
measurements as guidelines to achieve a 1
degree pitch on your machine.
