Automatic Controlled Traction (ACT)
Automatic Controlled Traction (ACT) applies a preset amount of torque to both rear wheels even if one starts to slip. A transmission without ACT will lose traction completely if one rear wheel starts to slip. This preset torque is just enough to give additional traction, and still let the wheels turn at different speeds in a tight turn without damage to the lawn.
Under certain circumstances, the ACT system limit can be exceeded, and one of the rear tires may slip. For example, if you turn up a hill, when you accelerate. This is normal. If you start to lose traction, do not speed up. Instead, slow to stop, straighten the steering wheel, and slowly accelerate. Stopping the tractor lets the transmission get more traction.

Cruise Control
To engage:

Push down on the cruise control lever (S, Figure 3) until the desired speed is reached.

To disengage:

Pull back on the cruise control lever or push the brake pedal (P).

Tire Pressure Check

For correct traction and best mowing performance, make sure that the tire inflation pressure is 12-14 psi (0,82-0,96 bar). Refer to Tire Pressure Check in the Maintenance Schedule. Also, see Tire Inflation Pressure in the Specifications section.
Note: The Tire Inflation Pressure can be slightly different from the “Maximum Inflation” shown on the side of the tires.

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.

NOTICE
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 (A, Figure 15) 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 as shown in Figure 16.

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.

Disconnect the Power Take-Off and stop the engine.
Turn the water OFF.
Remove the garden hose and quick disconnect from the washout port (C).

Storage

WARNING
Never store the unit (with fuel) in an enclosed, nonventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion.

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
Turn OFF the Power Take-Off (PTO), and set the parking brake. Remove the starter insert. Let the machine cool.
If you remove the battery, the battery life will increase. Make sure that the battery is in a cool, and dry location, and keep it fully charged. If the battery is left in the unit, disconnect the negative cable.

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 STA-BIL 360°
® PROTECTION™ 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 STABIL 360° ® PROTECTION™ is added as instructed. Before storage, turn the engine ON for 2 minutes to move the fuel and stabilizer through the fuel system.

Before starting the machine after it has been stored:

Check all fluid levels. Check all maintenance items.
Do all recommended checks and procedures found in this manual.
Make sure the engine is warm before you use it.

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.
