Oil Recommendations

Oil Capacity

We recommend the use of Briggs & Stratton Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF, SG, SH, SJ or higher. Do not use special additives. Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

A| SAE 30 – Below 40 °F (4 °C) the use of SAE 30 will result in hard starting.
---|---
B| 10W-30 – Above 80 °F (27 °C) the use of 10W-30 may cause increased oil consumption. Check oil level more frequently.
C| Synthetic 5W-30
D| 5W-30

Check Oil Level

Before adding or checking the oil Make sure the engine is level. Clean the oil fill area of any debris.

1. Remove the dipstick and wipe with a clean cloth.
2. Install and tighten the dipstick .
3. Remove the dipstick and check the oil level. Correct oil level is at the top of the full indicator  on the dipstick.
4. If oil level is low, slowly add oil into the engine oil fill C.
5. Do not overfill. After adding oil, wait one minute and then recheck the oil level.
6. Do not add oil at the quick oil drain , if equipped.
7. Reinstall and tighten the dipstick.

Oil Pressure

If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or activate a warning device on the equipment. If this occurs, stop the engine and check the oil level with the dipstick.  If the oil level is below the ADD mark, add oil until it touches the FULL mark. Start the engine and check for the correct oil pressure before you continue to operate the machine. If the oil level is between the ADD and FULL marks, DO NOT start the engine. Contact an authorized service dealer to correct the oil pressure problem.

Fuel Recommendations

Fuel must meet these requirements:

• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.

NOTICE: Do not use unapproved gasolines, such as E15 and E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. Use of unapproved fuels will cause damage to engine components, which will not be covered under warranty. To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. All fuel is not the same. If starting or performance problems occur, change fuel providers or change brands. This engine is certified to operate on gasoline. The emissions control system for this engine is EM (Engine Modifications).

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON) gasoline is acceptable. For carbureted engines, high altitude adjustment is required to maintain performance. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions. Contact a Briggs & Stratton Authorized Service Dealer for high altitude adjustment information. Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude adjustment is not recommended. For Electronic Fuel Injection (EFI) engines, no high altitude adjustment is necessary.

Adding Fuel

WARNING
Fuel and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. When Adding Fuel

• Turn engine off and let engine cool at least 3 minutes before removing the fuel cap.
• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
• Fill fuel tank outdoors or in a well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the bottom of the fuel tank neck.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting engine.
  • Clean the fuel cap area of dirt and debris. Remove the fuel cap
  • Fill the fuel tank with fuel. To allow for expansion of the fuel, do not fill above the bottom of the fuel tank neck
  • Reinstall the fuel cap.

Starting the Engine

WARNING
If you do not understand how a specific control functions, or have not yet thoroughly read the Features & Controls section, do so now. Do NOT attempt to operate the tractor without first becoming familiar with the location and function of all controls.

• While sitting in the operator’s seat, make sure the PTO switch is disengaged and the ground speed control levers are locked in the START/PARK position.
  Note:  The parking brake is automatically engaged when the ground speed levers are locked in the START/PARK position.

• Set the engine speed control past the FAST position to the CHOKE position.

Note
A warm engine does not require choking. Some engines are equipped with a separate choke control. Some engines are equipped with a Ready Start feature, and do not feature a choke.

•  Insert the key into the ignition switch and turn it to START.
•  After the engine starts, turn off the choke (if equipped), and warm up the engine by running it for at least a minute before engaging the PTO switch or driving the rider.
• After warming the engine, always operate the unit at full engine speed when mowing.
• In the event of an emergency the engine can be stopped by simply turning the ignition switch to STOP. Use this method only in emergency situations.
• For normal engine shut down follow the procedure given in Stopping The Rider And Engine .

Stopping the Rider

Return the ground speed levers to the middle (or neutral N’) position to stop rider movement. Pivot the levers outward to lock them in the START/PARK position.

Note

• Moving the ground speed levers to the START/ PARK position automatically engages the parking brak
•  Disengage the PTO by pushing down on the PTO switch
• Move the engine speed control to the SLOW position and turn the ignition switch to OFF.
• Remove the key.

Driving

Zero Turn Driving Practice

Before attempting to drive the zero-turn riding mower make sure you have read the Features and Controls section and understand the location and function of all of the unit’s controls. The ground speed control levers of this zero-turn riding mower are responsive, and learning to gain a smooth and efficient control of the unit’s forward, reverse, and turning movements will take some practice. Spending some time going through the maneuvers shown and becoming familiar with how the unit accelerates, travels, and steers, before you begin mowing, is absolutely essential to getting the most out of the zero-turn riding mower. Locate a smooth, flat area of your lawn, one with plenty of room to maneuver. Clear the area of objects, people, and animals before you begin. Operate the unit at mid-throttle during this practice session (ALWAYS operate at full throttle when mowing), and turn slowly to prevent tire slippage and damage to your lawn. We suggest you begin with the Smooth Travel procedure, and then advance through the forward, reverse, and turning maneuvers.

Smooth Travel

• The lever controls of the Zero Turn rider are responsive.
• The BEST method of handling the ground speed control levers is in three steps
• FIRST place your hands onto the levers as shown.
• SECOND to go forward gradually push the levers forward with your palms.
• THIRD  to speed up move the levers farther forward. To slow down smoothly, slowly move the levers toward neutral.

Basic Driving

Forward Travel Practice

Gradually move both ground speed control levers evenly FORWARD from neutral. Slow down and repeat.

NOTE
Straight forward travel takes practice. If necessary, top speed can be balance-adjusted see the Speed Balancing Adjustment in the Adjustments section.

Reverse Travel Practice

LOOK DOWN & BEHIND, then gradually move both ground speed control levers evenly BACK from neutral. Slow down and repeat.

NOTE
Practice backing up for several minutes before attempting to do so near objects. The rider turns sharply in reverse as well as forward, and backing up straight takes practice.

Practice Turning Around A Corner

While traveling forward allow one handle to gradually return back toward neutral. Repeat several times.

NOTE
To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.

Practice Turning in Place

To turn in place, Zero Turn gradually move one ground speed control lever forward from neutral and one lever back from neutral simultaneously.

NOTE
Changing the amount each lever is pulled forward or back, changes the “pivot point” you turn on.

Advanced Driving

Executing an End-Of-Row Zero Turn

Your Zero Turn Rider’s unique ability to turn in place allows you to turn around at the end of a cutting row rather than having to stop and Y-turn before starting a new row.
For example, to execute a left end-of row zero turn:

•  Slow down at the end of the row.
• Move the RIGHT ground speed control lever forward slightly while moving the LEFT ground speed control lever back to center and then slightly back from center.
• Begin mowing forward again.
• This technique turns the rider LEFT and slightly overlaps the row just cut eliminating the need to back up and re-cut missed grass.
• As you become more familiar and experienced with operating the Zero Turn rider, you will learn more maneuvers that will make your mowing time easier and more enjoyable.
• Remember, the more you practice, the better your control of the Zero Turn will be!

Mowing

• Make sure the PTO switch is disengaged, the ground speed control levers are locked in their START/PARK positions, and the operator is in the seat.
• Start the engine. See Starting the Engine .
• Set the mower cutting height. See Cutting Height Adjustment .
• Set the engine speed control to FAST.
• Engage the PTO by pulling up on the PTO switch.
• Pivot the ground speed levers in from the START/PARK position to the neutral ‘N’ position.
• Begin mowing. See Operator Safety for tips on safe mowing practices.
• When finished, shut off the PTO.
• Stop the engine. See Stopping The Rider And Engine .

Centre Cut Mower Decks

Some models feature a Centre Cut mower deck that can be configured for side discharge or rear eject operation. To convert between available mower deck configurations, see your dealer.

WARNING

Suspension Adjustment (if equipped)

The shock assemblies front shown, rear similar) can be adjusted to vary the amount of pre-load applied to the springs. This allows the operator to customize the ride according to operator’s weight and operating conditions.

Less Pre Load:

•  Light operator weight
•  Softer, more cushioned ride
•  Best for relatively flat terrain

More Pre Load

•  Heavy operator weight
• Stiffer, more rigid ride
• Better handling and greater stability on hilly terrain

To Adjust the Spring Pre Load

Park machine on a flat, level surface. Disengage the PTO, pivot the ground speed levers out to the START/PARK position, and stop the engine.
Turn the pre-load adjustment collar  to a higher notch (-) to decrease the pre-load, or to a lower notch (+) to increase the pre-load. Make sure all shocks are set to the same amount of pre load.

Check the Spark Plugs

WARNING

• Unintentional sparking can result in fire or electric shock.
• Unintentional start-up can result in entanglement, traumatic amputation, or laceration.
• When testing for spark
  • Use approved spark plug tester.
  •  Do not check for spark with spark plug removed.
  • Spark plugs have different heat ranges.
• It is important that the correct spark plug is used, otherwise, engine damage can occur.
• Replace the spark plug with the same type or equivalent one.

Clean Spark Plug

• Clean the spark plug with a wire brush and sturdy knife.
• Do NOT use abrasives.

Check Spark Plug Gap

Use a spark plug feeler gauge to check the gap between the two electrodes. When the gap is correct, the gauge will drag slightly as you pull it through the gap. To adjust the spark plug gap, use a spark plug gauge and gently bend the curved electrode. Make sure that you do not touch the center electrode or the porcelain.

Install Spark Plug

Tighten the spark plug with your fingers, and then, tighten it with a wrench 180 in lbs 20 Nm OR 1/2 turn when you install the original spark plug 1/4 turn when you install a new spark plug.

Pushing the Rider By Hand

Unsafe Operation Hazard

DO NOT disengage the transmissions and coast down slopes. DO NOT use Roll Release to disengage the transmissions unless machine motion can be controlled and engine is off.

NOTICE

Do not tow rider. Towing the unit will cause transmission damage. Do not use another vehicle to push or pull this unit.

1. Disengage the PTO, lock the ground speed levers into their START/PARK positions, turn the ignition OFF, remove the key, and wait for all moving parts to stop.
2. To disengage the transmissions, move the roll release levers depending on model), into the PUSH position.
3. Pivot the ground speed levers in from the START/ PARK position to the neutral ‘N’ position to disengage the parking brake.
4. The rider can now be pushed by hand.
5. After moving the rider, re-engage the transmissions by moving the roll release levers back to the DRIVE position.

Cleaning

1. Clean dirt and debris from the rider and mower deck. Note: Some mower decks feature a washout port.
2. Clean any debris buildup in the engine compartment and from on or around the engine.

WARNING

Fire Hazard

Yard debris is combustible.

• Clean dirt and debris from the rider and mower deck.
• Clean build-up from around the engine.

Washing The Mower Deck

The washout port allows you to connect a typical garden hose to the left hand side of the mower deck to remove grass and debris from the underside.

WARNING

Amputation and Thrown Object Hazard

Contact with the mower blades, or with objects thrown by the mower blades, could result in death or serious injury. Before running the mower, make sure the hose is properly connected and does not come into contact with the blades. When the mower is running and the blades are engaged, the person cleaning the mower deck must be in the operator position, with no bystanders in the area.1. Place the unit on a smooth level surface. Attach the quick disconnect to garden hose and connect to the washout port (A) on the mower deck. Run water to remove grass and debris from the underside of the mower deck. Turn the mower on and place in the highest cutting position. Turn the mower off. Remove the garden hose and quick disconnect from the washout port when completed.

Storage

WARNING

Fire and Explosion Hazard
Never store the unit (with fuel) in a closed structure without sufficient airflow. Fuel vapors can travel to an ignition source such as a furnace, water heater, etc. and cause an explosion. Fuel vapor is also toxic to humans and animals.

When Storing Fuel Or Equipment With Fuel in Tank

Store away from furnaces, stoves, water heaters, or other appliances that have pilot lights or other ignition sources because they can ignite fuel vapors.

Equipment

Disengage the PTO, lock the ground speed levers in the START/PARK position, and remove the key. Battery life will be increased if it is removed. Put in a cool, dry place and keep fully charged during storage. If the battery is left in the unit, disconnect the negative cable.

Engine Oil

While the engine is still warm, change the engine oil. Before starting the unit after it has been stored .

• Check all fluid levels. Check all maintenance items.
• Do all recommended checks and procedures.
• Let the engine warm up for several minutes before use.

Storage Fuel System

Fuel can become stale when kept in a storage container for more than 30 days. Each time you fill the container with fuel, add fuel stabilizer to the fuel as specified by the manufacturer’s instructions. This keeps fuel fresh and decreases fuel-related problems or contamination in the fuel system. It is not necessary to drain fuel from the engine when fuel stabilizer is added as instructed. Before storage, turn the engine ON for 2 minutes to move the fuel and stabilizer through the fuel system.

Power Ratings

The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive Engineers code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are derived at 2600 RPM for those engines with rpm called out on the label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given the wide array of products on which engines are placed, the gasoline engine may not develop the rated gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc., application limitations, ambient operating conditions temperature, humidity, altitude, and engine-to-engine variability. Due to manufacturing and capacity limitations Briggs & Stratton may substitute an engine of higher rated power for this engine. The engine information contained in this manual applies to Briggs & Stratton engines only.
