INTRODUCTION

HDZ ZT 01/17 Introduction Section 2-2

The Bush Hog Zero Turn is intended for use on lawns and other frequently maintained areas where a smooth, even cut is desired and superior maneuverability is needed. The Power Unit consists of a Briggs & Stratton, Kawasaki, or Kohler twin cylinder engine. The engine has a pressurized oil lubrication system with spin-on type filter, fused electronic ignition, electric start and the Zero Turn has a 9 gallon fuel system.

Two hydrostatic transaxles are used for propelling and steering. The Transaxles are belt driven by the engine output shaft. One lever for each drive controls both speed and direction. This independent control of each drive wheel coupled with continuously variable speed selection gives the Zero Turn mower exceptional maneuverability.

The Zero Turn Mower Deck is available in 61” or 73” cutting widths. The Zero Turn Mower has three cutting blades, driven by an electromagnetic clutch through a single v-belt.

Front, rear, left and right are determined by the normal direction of travel, the same as driving an automobile.

Ignition Switch

Choke and Throttle

The Ignition Switch is keyless and is the Red Button on the Console located on the right hand side of the Zero Turn Mower. This controls starting and stopping the engine.

A 4 digit code must be entered before the engine can be started.

This code will be supplied by the dealer at the time the purchaser takes ownership of the Zero Turn Mower. A code is programmed at the factory for use until

the owner changes it to his personal code.

It is recommended that the owner personalize the code as soon as possible after taking ownership of the Zero Turn Mower.

See Personalizing Your Key Code.

PERSONALIZING YOUR KEY CODE

1. Record your new Key Code (1-12 digits) for safe keeping. NOTE: Only a dealer service call can reset a for

gotten code.

2. Engine must be stopped and console unlocked (using the original code that comes with the Zero Turn Mower) and the PTO Switch down (OFF).

3. Hold KEY CODE BUTTONS 1 & 2 simultaneously for three seconds until the display shows “CHNGE” “CODE” followed by a blank screen.

4. Enter the new key code into the console. If more than 12 digits are used the display shows “FULL” NOTE: The display always shows the 5 most recently entered digits.

5. After entering the new code, pull the PTO Switch up. If the new code is unusable, the display will show “BAD” “CODE”. If this occurs push the PTO switch down and return to step 1 and try a different code. NOTE: If user does not enter a code and pulls the PTO switch up the display shows “EMPTY” “CODE”.

IGNITION

CHOKE

The Choke provides a richer fuel mixture to the engine to assist on cold starts. Pull the choke up to engage and once the engine starts push down to disengage.

THROTTLE

The Throttle controls the engine speed and blade speed when blades are engaged. To increase the engine and blade speeds push the Throttle forward and to decrease the speeds push the throttle toward the back. For best mowing performance run the engine at full throttle and control your ground speed with the Steering levers.

6. If the new code is usable, the console prompts the user to re-enter the code again by displaying: ENTER” “CODE” “AGAIN”. Re-enter the code used in step 4,

then push the PTO switch down

7. The console confirms that the two key codes entered in step 4 and 6 match. If they do match, the console saves the new unlock code and displays “SAVED” “CODE” before returning to the previous display mode. If they do not match the console displays “NO” “MATCH” and the user must return to step 1.

NOTE: If no input is received for 10 seconds the console displays”TIME” “OUT” before returning to the previous display mode, retaining the previous unlock code.

Steering Control Levers

Steering Control Levers control the direction and speed of the Zero Turn Mower in both forward and reverse travel. Turning is controlled by pushing one lever forward and pulling the opposite lever backward or to the neutral position. Moving the levers forward equally will cause the Zero Turn Mower to travel forward in a straight line. Moving the levers backward equally causes the Zero Turn Mower to travel in reverse. The further the levers are

moved forward or backward increases the speed of travel in that direction.

THE ZERO TURN MOWER WILL

TURN VERY RAPIDLY IF ONE

STEERING LEVER IS MOVED MUCH FURTHER

FORWARD THAN THE OTHER.

Moving the right hand lever forward and the left hand lever to the neutral position turns the Zero Turn Mower left. Moving the left hand lever forward and the right hand lever to the neutral position turns the Zero Turn Mower

to the right.

Moving the right hand lever forward and the left hand lever backward the Zero Turn Mower will achieve a zero turn to the left. Moving the left hand lever forward and the right hand lever backward achieves a zero turn to the right. These maneuvers should be done with extra

care at a slow speed when turning.

The Parking Brake is located on the left side of the Zero Turn Mower. To set the brake pull the lever up and push down to release. When engaging the brake the Zero Turn Mower must be completely motionless. Always set the

Parking Brake before dismounting the Zero Turn Mower and always release the brake before putting the Zero Turn Mower into operation.

NOTE: If the Parking Brake is not set in the Park position when starting, the engine will not start and the Parking Brake LED will be lit on the console. Release the brake after the engine has started.

OPERATION

HDZ ZT 01/17 Operation Section 4-2

Steering

Direction of travel and speed are controlled by the Steering Control Levers. The right hand lever controls the right

wheel and the left hand lever controls the left wheel.

All procedures listed below should be performed slowly and with caution

until the operator is confident in their ability to operate this Zero Turn Mower SAFELY.

Begin with the operator sitting in the seat and adjust the seat so the operator feels comfortable with the steering controls and can easily raise and lower the deck with the Foot Control Pedal.

Begin by bringing the engine to idle speed. Release the Parking Brake. Move the Steering Levers inward from the Neutral Lock position to the Neutral position.

To Move Forward or Backwards

Pushing the Steering Lever forward equally causes the Zero Turn Mower to travel forward in a straight line. The further forward the Levers are pushed the travel speed will increase.

Pulling the levers backward equally causes the Zero Turn Mower to travel in reverse and speed increases the further back they are pulled.

To Turn Left

To negotiate a left hand turn while moving forward pull the left hand lever backward toward the neutral position slowing the left wheel causing the Zero Turn Mower to turn left.

To Turn Right

To negotiate a right hand turn while moving forward pull the right hand lever backward toward the neutral position slowing the right wheel causing the Zero Turn Mower to turn right.

To Perform a Zero Turn

Bring both Steering Levers to the neutral position until the Zero Turn Mower slows or stops.

Pushing the Left Lever slightly forward and pulling the Right Lever slightly backward negotiates a Right Hand Zero Turn.

Pushing the Right Lever slightly forward and pulling the Left Lever slightly backward negotiates a Left Hand Zero Turn.

Operating the Mower

The Mowing Height is controlled by the Foot Control Pedal and a Height Adjusting Knob.

Mowing Height is adjustable from 1-1/2” to 5-1/2” in 1/4” increments.

NOTE: Mowing Height Adjustment should only be made

with the Zero Turn Mower deck blades disengaged.

To adjust the Mowing Height, place the right foot on the Foot Control Pedal and push forward. Turn the Knob to the desired cutting height to align with the indicator on the panel. Release the Foot control Pedal. When the mowing height has been established, start the

Zero Turn Mower, pull the PTO Switch up to engage the blades. Engine should be at full throttle when engaging

the blades.

When engaging the blades make sure no one is near to the Zero Turn

Mower.

Be sure the area to be mowed has been cleared of all debris that could be thrown by the rotating blades causing injury to bystanders and damage to the Zero Turn Mower.

Best mowing results are achieved when the engine is at full throttle and ground speed is controlled by the Steering Levers.

When mowing is completed, disengage the Zero Turn Mower deck blades by pushing the PTO Switch down.

Raise the Zero Turn Mower by pushing the Foot Control Pedal and place the Height Adjusting Pin in the 5” hole for transporting to the next location.

Mowing Tips

Before mowing check the area to

be mowed for debris that can be removed. Objects that are fixed and cannot be removed, flag the object so a collision does not occur.

●Start by setting the Zero Turn Mower at the desired cut-

ting height so desired result is attained. The

average lawn should be cut to a height of 2-1/2’’ during cool seasons and 3” during hot months. For healthier, better looking lawns mow often after moderate growth has occurred.

●Grass over 6” in height should be mowed twice. Make

the first cut relatively high and then mow a second time at desired height.

●Mowing results are best when the engine is a full throt-

tle (blades spin faster) and the travel speed is

low. If grass is low, travel speed can increase without affecting mowing results.

●Avoid mowing when grass is damp or wet. The mowing

results can be poor and cause the wet grass to clump under the deck and stick to the underside of the mow-

ing deck, resulting in an uneven cut.

After Mowing is Completed

●After the Zero Turn Mower is shut down and the engine

has cooled, use compressed air to clean the top surfaces of the Zero Turn Mower deck and frame. If compressed air is not available a leaf blower can be used.

●Avoid using water on top surfaces around engine and

electrical components.

●Raise the Zero Turn Mower deck to its highest position

and hose the underside of the Zero Turn Mower deck

to remove any build up of grass clippings.

Mowing Near Water, Ditches, and Embankments

Operating this Zero Turn Mower

near water where drop offs are present is unsafe. Wheels dropping over the edge can cause rollover or loss of traction resulting in serious injury or death by drowning.

Refer to SAFETY SECTION: Using ROPS & Seat Belts For Operating on Slopes Safety.

●Watch for ditches, holes, rocks, dips and rises that can

change the operating angle. Keep away from drop offs and steep banks. Tall grass can hide these obstacles.

●Use caution near drop offs, ditches, or embankments.

The Zero Turn Mower can suddenly turn over if a wheel goes over an edge of a ditch, drop off, embankment, or an edge caves in.

●Mow a safe distance from water’s edge (Ponds or

Lakes). A Danger Zone of 10 feet should be observed.

Transaxle Maintenance

This Zero Turn Mower has two Transaxles. The Transaxles have serviceablel filters for ease of maintenance. To ensure fluid quality and longer life, changing the oil and filter after the initial 100 hours of Zero Turn Mower usage then in 400 hour intervals thereafter is recommended.

NOTE: Recommended oil is API classification of SL is recommended. A 20W-50 engine oil has been selected for use by the factory and is recommended for normal operating temperatures.

NOTE:Biodegradable oils are not approved for this

unit as they degrade too quickly while in service.

Fluid and Filter Change Procedure

The following procedure can be performed with the transaxle installed in the vehicle. The Zero Turn Mower must be parked on a level surface, parking brake set and bypass valve on each transaxle applied.

Allow the Zero Turn Mower to cool down before proceeding to perform maintenance.

1. Place an oil drain pan (12” or more in diamter and 8 qt. capacity is optimal) beneath the oil filter. Remove the oil filter cover from the transaxle to drain the oil. Remove the O-ring from the cover and discard the Oring. Use Bush Hog Filter Kit 50072375 (Includes “O” Ring and Filter). Two Kits required per Zero Turn Mower.

2. After the oil has drained from the transaxle, remove the oil filter from the transaxle housing.

3. Install a new filter and a new O-ring onto the filter cover and install the filter cover.

4. Remove the top oil fill vent port plug and fill the transaxle with new 20W50 motor oil through the expansion tank port/fill port until oil reaches the oil fill vent port.

5. Install the top oil fill vent port plug and continue filling the system with oil until the fill line is reached in the expansion tank.

6. Drain old oil filter of all free flowing oil prior to disposal. Place used oil in appropriate containers and deliver to an approved recycling collection facility.

7. Proceed to the Purging Procedures.

Purging Procedures

These purge procedures should be implemented any time a hydrostatic system has been opened to facilitate maintenance or the oil has been changed.

Due to the effects air has on efficiency in hydrostatic drive applications, it is critical that it is purged from the system. Air creates inefficiency because its compression and expansion rate is higher than that of the oil approved for use in hydrostatic drive systems.

The resulting symptoms in hydrostatic systems may be:

1. Noisy operation.

2. Lack of power or drive after short term operation.

3. High operation temperature and excessive expansion of oil.

Before starting, make sure the transaxle is at the proper oil level. If it is not, fill to the specifications outlined in this manual. Refer to steps 4-5 under Fluid and Filter Change Procedure

The following procedures are best performed with the vehicle drive wheels off the ground. Then repeated under normal operating conditions.

If this is not possible, then the procedure should be performed in an open area free of any objects or bystanders.

1. Disengage the brake if activated.

2. With the bypass valve open and the engine running, slowly move the directional control in both forward and reverse directions (5 or 6 times).

3. With the bypass valve closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level, and add oil as required after stopping the engine.

4. It may be necessary to repeat Steps 2 and 3 until all the air is completely purged from the system. When the transaxle operates at normal noise levels and moves smoothly forward and reverse at normal speeds, then the transaxle is considered purged.

Console Maintenance

General Care

The Console is a completely sealed instrument designed to withstand exposure to outdoor environments. Pressure washing of the console face is acceptable when water spray pressure does not exceed 2000 psi while using a 30 degree or greater nozzle tip (fan spray) at a distance no closer than 12”. Oil, gasoline, chemicals and detergents spilled on the console should be wiped off immediately with a clean dry cloth.

Never use abrasive or corrosive cleaning products on the console.

Bypassed or Failed Safety Interlock Switch Detection

While monitoring the safety interlocks, the console identifies interlock switches that have failed, closed, or have been bypassed closed. When the console detects a failed or bypassed switch, it slowly flashes the corresponding indicator LED and flashes “SEAT”/”BRAKE”/”DRIVE” “INTLK” “FAULT” on the LCD.

The console allows the equipment to continue operating normally for a short time after detecting a potentially faulty switch to allow the equipment to return to a service area, locking out engine operation after this time is exhausted.

To clear this error, replace or repair the faulty interlock switch and open the switch while the console is unlocked by entering your Key Code.

Service Alerts

Service alerts remind the operator to perform specific maintenance tasks based on equipment run time. While the console is unlocked by entering your Key Code, click key code button 1 (12) once to enter service alert display, and again as needed to select the desired alert to display. The display returns to engine hour meter after 30 seconds of inactivity.

To Reset A Service Alert:

Select the service alert to reset by clicking keypad button 1(12) until the LCD shows the desired service message. c. Press and hold keypad button 1 (12) for 6 seconds. d. Release the button when the LCD shows “00000”.

Alarms

Low Oil Alarm - If the oil pressure switch closes for ten

seconds while the engine is running, the console displays “OIL” “PSI” on the LCD (11), flashes the low oil alarm LED indicator, and shuts down the engine. The alarm is reset when the engine is restarted, or when the console goes to sleep.

The alarm may also be configured to lock out the PTO but leave the engine running. In this configuration, the alarm is immediately reset when the oil pressure switch opens.

Low Voltage Alarm - While the console is unlocked by entering your Key Code, and the system voltage is below

12.0 V for 90 seconds, the console displays “LOW VOLTS” and the current system voltage. This alarm is reset when the system voltage rises above 12.0 V or when the console goes to sleep.

High Voltage Alarm - While the console is unlocked by entering your key code, and the system voltage is above

15.0 V for more than 2 seconds the console displays “HIGH VOLTS” and the current system voltage. This alarm is reset when the system voltage drops below 15.0 V or when the console goes to sleep.

STORAGE

HDZ ZT 01/17 Storage Section 7-1

Winter Storage

At the end of the mowing season, or when it will not be in use for more than 30 days, the Zero Turn Mower should be readied for storage. Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function. Fuel stabilizers are an acceptable option as regards to the sticky residues that can occur during storage. Add stabilizer to the fuel in the tank and in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if you have added stabilizer.

Never store an engine with fuel in

the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. Gasoline Fumes are very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame or sources of ignition. Never use gasoline for cleaning. Use a degreaser and warm water instead.

Preparing the Machine for storage:

1. Thoroughly clean the Zero Turn Mower, especially under the Zero Turn Mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the Zero Turn Mower deck to avoid corrosion.

2. Inspect the Zero Turn Mower for worn or damaged parts and tighten any nuts or screws that may have become loose.

3. Change the engine oil; dispose of properly.

4. Empty the fuel tanks or add a fuel stabilizer. Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.

5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then re-install the spark plugs.

! WARNING

6. Lubricate all grease fittings, joints, and axles.

7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold or freezing.

8. Store the Zero Turn Mower in a clean, dry place and cover it for extra protection.

New Season Preparation

Before starting the mower following post season storage,

the following service is required:

Always check that fresh oil has been added to Zero Turn Mower. If oil is drained at season’s end and not replaced, engine damage will result.

1. Clean Zero Turn Mower, removing trash and dirt accumulation.

2. Check engine oil and hydraulic oil levels.

3. Fill fuel tank with fresh fuel. Run Zero Turn Mower at half speed for 5 minutes, checking operation of steering control lever. Stop engine and check for oil leaks, loose fittings.

4. Tighten any bolts that have loosened and make sure all hair pins, cotter pins and clevis pins are in place.

5. Check that all safety shields are in place and secure and review safety precautions listed in this manual.

6. Check Mower belt and drive belt for damage or severe cracking and replace if needed.

7. Check Mower blades for sharpness and damage. Replace or sharpen if needed.

8. Check and inflate tires to 15 psi / 1 bar / 103 kPa.

9. Install fully charged battery and attach the battery cables.

10. Check Safety system startup. Refer to Safety Sys

tem in the Maintenance Section.

11. Refer to engine manual for more information.

IMPORTANT!
