Getting Started with Your Craftsman T240 Riding Mower
Welcome to the world of effortless lawn care with your new Craftsman CMXGRAM1130044 T240 riding mower. This versatile machine is designed to make mowing a pleasure rather than a chore. Before you hit the lawn, it's crucial to ensure your mower is correctly assembled and ready for operation. This guide will walk you through the essential setup steps, operational controls, maintenance tips, and common troubleshooting solutions, drawing directly from the provided operator's manual.

Tractor Preparation: Ensuring a Smooth Start
Proper preparation is key to a long and productive life for your Craftsman T240. Here’s what you need to do:
Manually Moving the Tractor
For initial positioning or if the engine isn't running, you might need to move the tractor manually. Locate the transmission bypass rod on the rear of the tractor frame. Pull this rod outwards to disengage the transmission, allowing you to push the tractor. Remember to push the rod back in to re-engage the transmission before operating the mower. If the tractor doesn't move freely, ensure the bypass rod is fully engaged or that the brake isn't applied.
Installing the Operator’s Seat
If your seat assembly requires installation, follow these steps carefully:
- Remove any securing straps and packing material from the seat assembly. Be extremely cautious not to cut the wiring harness connected to the seat switch.
- Locate and remove the two shoulder screws and flange lock nuts from the seat pan.
- Position the seat correctly onto the tractor.
- Secure the seat using the previously removed shoulder screws and flange lock nuts. Ensure the wire harness is not crimped or damaged during this process.
- Use the provided harness clip to secure any excess wiring to the fender.
Lower Deck Discharge Chute Deflector
Check the mower deck for any shipping braces that might be holding the chute deflector in an upward position. If a brace is present, lift the deflector fully upwards and remove the brace. Then, lower the deflector to its normal position.
Installing the Front Bumper (If Equipped)
If your model includes a front bumper, the necessary hardware is likely pre-installed. Remove the four hex screws from the bumper. Position the bumper brackets inside the tractor’s frame and secure them using the four hex flange screws.
Adjusting the Seat
For optimal comfort and control, adjust your seat. Lift the seat adjustment lever, slide the seat to your preferred forward or rearward position, and release the lever. Ensure the seat is securely locked in place before operating.
Connecting the Battery Cables
For shipping purposes, battery cables may be disconnected. Identify the positive (+) and negative (-) terminals. Attach the red cable to the positive terminal and the black cable to the negative terminal using the provided bolts and hex nuts. Replace the protective rubber boot on the positive terminal. If the battery date indicates it hasn't been serviced recently, charge it according to the manual's instructions.
Setting the Deck Wheels
The deck wheels are an anti-scalp feature and should have a small clearance. On a level surface, check tire pressure and ensure the deck is level. Adjust the deck wheels so there is between 1/4" and 1/2" clearance above the ground when the deck is set to your desired mowing height. To adjust, raise the deck to its highest setting, remove the wheels by undoing the flange lock nuts and shoulder bolts, set the deck to your desired mowing height, reinsert the bolts into the appropriate index hole for the correct clearance, and tighten the nuts.
Fuel and Oil: The Lifeblood of Your Mower
Proper fuel and oil management is essential for engine health and performance.
Fuel Recommendations
Use unleaded or low-lead automotive gasoline with a minimum of 87 octane. Gasoline containing up to 10% ethanol or 15% MTBE is acceptable. Never use a gas/oil mixture or contaminated fuel. Refuel in a well-ventilated area with the engine off, and avoid smoking or open flames. Do not overfill the tank and ensure the cap is securely closed. Wipe up any spilled fuel before starting the engine.
Adding Fuel
Ensure the engine is off and the area is well-ventilated. Clean the fuel cap area, then slowly add fuel from an approved container until it reaches the bottom of the fuel tank neck. Replace and tighten the fuel cap securely. Clean up any spills immediately.
Engine Oil
Always refer to your Engine Operator’s Manual for specific oil type and capacity. The tractor may feature an oil service minder that alerts you when an oil change is due (typically every 50 hours). A "LO OIL" indicator signifies low oil pressure or level, requiring an immediate check of the oil level. Note that the low oil function relies on an oil pressure switch.
Operating Your Craftsman T240
Understanding the controls will make operating your mower intuitive and safe.
Control Pedals
- Forward Drive Pedal: Located on the right side. Pressing it forward controls speed; the further you press, the faster you go.
- Reverse Drive Pedal: Located on the right side. Pressing it downwards controls reverse speed.
- Brake Pedal: On the left side. Used for stopping and engaging the parking brake. Must be fully depressed to start the engine.
- Differential Lock Pedal (if equipped): On the left side. Engages for increased traction in slippery conditions.
Throttle/Choke Control
This lever, on the left dash, controls engine speed. Pushing it fully forward, past the detent, activates the choke for cold starts. Always operate the cutting deck with the throttle in the FAST position.
Parking Brake
To set, fully depress the brake pedal, press down and hold the parking brake/cruise control lever, then release the brake pedal. The pedal should remain down. To disengage, lightly press the brake pedal.
Cruise Control
To set, reach your desired speed with the forward pedal, then press and hold the parking brake/cruise control lever. Release the forward pedal; it should stay down to maintain speed. To disengage, lightly press either the forward or brake pedal. Cruise control cannot be set at the tractor's maximum speed.
Deck Lift Lever
Move the lever left and into the desired notch to raise or lower the cutting deck.
Headlights
Headlights are active when the ignition key is turned from the STOP position.
Engaging the PTO (Power Take-Off)
This engages power to the cutting deck or other attachments. Ensure the throttle is in the FAST position. For electric PTO models, pull the PTO switch up. For manual PTO, push the PTO handle forward. To disengage, push the PTO switch down or pull the PTO handle rearward.
Mowing Techniques for a Perfect Lawn
Achieve a professional finish with these mowing tips:
- Avoid engaging the mower deck while it's lowered in tall grass. Raise it first.
- Mow up and down slopes, not across. If a turn is necessary on a slope, turn downhill.
- Avoid stopping on slopes if possible. If you must stop, accelerate smoothly to prevent tipping.
- Set the throttle to FAST and engage the PTO. Lower the deck to the desired height.
- Control your ground speed with the forward drive pedal. Mowing too fast can affect cut quality.
- When turning at the end of a row, slow down or stop before turning. Align the mower for the next strip, overlapping approximately 3 inches.
- To prevent turf damage, alternate mowing direction by about 45 degrees each time you mow.
Using the Differential Lock
When encountering poor traction, stop the tractor using the brake pedal. Press the differential lock pedal to engage. The lock engages when wheel speed differences are detected and disengages when speeds equalize. Release the brake pedal to move. The lock only functions while the pedal is pressed.
Service and Maintenance: Keeping Your Mower in Top Shape
Regular maintenance ensures longevity and peak performance.
Cleaning the Underside of the Deck
Utilize the deck wash system after each mowing. Connect a garden hose to the water port, start the engine, set the throttle to FAST, and engage the PTO for at least two minutes. This flushes out clippings and prevents corrosion. After rinsing, run the deck for another two minutes to dry the underside.
Cleaning the Tractor
Clean the tractor after each use, especially in dry or mulching conditions. Use compressed air or a leaf blower to remove debris from around the engine, under the hood, and around the transmission. Avoid using water on most parts of the tractor, as it can damage bearings and electrical components. Promptly clean any fuel or oil spills to reduce fire hazards. Do not mow excessively tall, dry, or piled grass/leaves, as this can create a fire risk.
Changing the Engine Oil
Warm the engine slightly to help the oil flow. Locate the oil drain hose, place a suitable container underneath, and remove the oil fill cap. Open the drain valve, attach the provided drain tube, and drain the oil. Close the valve, replace the oil filter (place a towel to catch drips), and refill with the correct type and amount of oil as specified in your Engine Operator’s Manual.
Off-Season Storage
To prepare for storage:
- Treat the fuel with a stabilizer or drain the fuel system completely to prevent gum formation. Run the engine briefly after adding stabilizer to circulate it. If draining, run the engine until it stalls or disconnect the fuel line and drain.
- Remove the spark plug, pour about an ounce of engine oil into the cylinder, and crank the engine a few times to distribute the oil. Replace the spark plug.
- Clean debris from the engine and other areas, touch up paint, and lightly oil areas prone to rust.
- Store the tractor in a clean, dry, well-ventilated area away from ignition sources and high humidity.
- Ensure the tractor remains level during storage.
Removing From Storage
Check the oil level. If fuel was drained, fill the tank with fresh gasoline. The engine may smoke briefly on startup if the cylinder was oiled, which is normal.
