Speed Selection: The seven forward and seven reverse speeds allow for precise maneuvering around obstacles and efficient operation in both large open areas and tight spaces․ Selecting the appropriate speed optimizes cutting quality and reduces operator fatigue․
Maintenance Considerations: Regularly check the transmission fluid level and condition․ Refer to the maintenance schedule for recommended fluid change intervals․ Proper transmission maintenance ensures reliable performance and extends the lifespan of this critical component․ Avoid abrupt shifts and excessive strain on the system․
Operating Instructions
Get Started Safely: This section details the proper procedures for starting, operating, and safely stopping your Craftsman T140 riding lawn mower efficiently․
Starting and Stopping the Engine
Pre-Start Checks: Before attempting to start your Craftsman T140, ensure the blade is disengaged, the parking brake is firmly applied, and no obstructions are present around the mower deck․ Verify sufficient fuel levels and oil levels according to the engine specifications․
Starting Procedure: Turn the ignition key to the ‘ON’ position․ If the engine is cold, engage the choke․ Depress the brake pedal and turn the key further to the ‘START’ position, holding it until the engine ignites․ Gradually release the choke as the engine warms up․
Stopping Procedure: To stop the engine, disengage the blades, shift the transmission into neutral, and slowly turn the ignition key to the ‘OFF’ position․ Always allow the engine to come to a complete stop before dismounting․ Remember to remove the key to prevent accidental starting․
Mowing Techniques for Optimal Results
Overlap & Direction: For a clean, even cut, overlap each mowing pass by approximately one-third of the blade width․ Alternate mowing direction with each subsequent cut to prevent grass from leaning in one direction, ensuring a healthier lawn․
Mowing Speed: Maintain a consistent, moderate mowing speed․ Avoid rushing, as this can lead to an uneven cut and increased strain on the engine․ Adjust speed based on grass height and density․
Grass Height: Never remove more than one-third of the grass blade length at a time․ This promotes healthy growth and prevents scalping․ Regularly mowing at the appropriate height encourages a thicker, more resilient lawn․ Consider mulching clippings for added nutrients․
Adjusting Cutting Height
Height Adjustment Levers: The Craftsman T140 utilizes individual height adjustment levers on each wheel․ These levers offer multiple height settings, typically ranging from 1 to 4 inches․ Ensure all four levers are set to the same position for a level cut․
Procedure: To raise the deck, move the levers to a higher numbered setting․ To lower the deck, move them to a lower number․ Always stop the engine and engage the parking brake before adjusting cutting height․
Checking for Level: After adjustment, verify the deck is level by measuring the distance from the blade tips to the ground at multiple points․ Fine-tune the levers as needed for a consistently even cut․ Regular checks are recommended․
Maintenance & Repair
Essential upkeep ensures your Craftsman T140’s longevity and peak performance; this section details routine tasks and repair procedures for optimal operation․
Routine Maintenance Schedule
Regular maintenance is crucial for a long-lasting and efficiently operating Craftsman T140․ After each use, inspect the mower deck for debris and thoroughly clean it․ Check the tire pressure and ensure all bolts are tightened securely․
Every 25 hours of operation, or annually, change the engine oil using the recommended SAE 30 oil․ Clean or replace the air filter to maintain optimal engine performance․ Inspect the drive belt for wear and tear, replacing it if necessary․
Seasonally, before storing the mower, stabilize the fuel or drain the fuel tank to prevent gumming․ Lubricate all moving parts, including the wheels and steering components․ A thorough inspection of all components will ensure readiness for the next mowing season․ Always refer to the engine manufacturer’s manual for specific oil and filter recommendations․
Blade Sharpening & Replacement
Maintaining sharp blades is essential for a clean cut and healthy lawn․ Inspect blades regularly for dullness, nicks, or damage․ Sharpening can be done with a file or a blade grinder, ensuring the original angle is maintained for balanced cutting․
When sharpening, always wear gloves and eye protection․ If blades are severely damaged, bent, or cracked, they must be replaced․ Use only genuine Craftsman replacement blades or equivalent․
To replace blades, securely block the wheels, disconnect the spark plug wire, and use a wrench to remove the blade bolt․ Install the new blade, ensuring it’s facing the correct direction, and tighten the bolt to the manufacturer’s specified torque․ Always balance the blade after sharpening or replacement to prevent vibration․
Belt Replacement Procedures
Replacing worn belts is crucial for maintaining proper transmission function․ Begin by disconnecting the spark plug wire for safety․ Locate the belt(s) requiring replacement – typically the deck belt or the transmission belt․
Carefully remove any covers or guards obstructing access to the belt․ Note the belt routing before removal; a diagram can be helpful․ Use a belt tool or wrench to relieve tension and remove the old belt․
Install the new belt, following the original routing precisely․ Ensure the belt is seated correctly in all pulleys․ Reinstall covers and guards, and reconnect the spark plug wire․ Always verify proper belt tension and operation before resuming mowing․
Troubleshooting Common Issues
Diagnosing problems quickly ensures your Craftsman T140 remains operational; this section provides solutions for engine, deck, and transmission related difficulties․
Engine Won’t Start – Diagnosis & Solutions
A non-starting engine is a frequent issue․ First, verify the fuel tank isn’t empty and the fuel shut-off valve is open․ Check the spark plug – disconnect it, inspect for fouling, and ensure a proper gap․ If the plug is wet, the engine may be flooded; allow it to dry․
Next, examine the air filter; a clogged filter restricts airflow․ Confirm the safety interlocks are engaged correctly – the seat switch and blade engagement lever must be activated․ Inspect the starter solenoid; a faulty solenoid won’t engage the starter․
If these steps don’t resolve the issue, a carburetor problem might exist, potentially requiring cleaning or rebuilding․ Always disconnect the spark plug wire before performing any maintenance․ Consult a qualified technician if you’re uncomfortable with these procedures․
Deck Issues – Uneven Cut, Noise
An uneven cut often indicates dull or damaged blades․ Sharpen or replace blades, ensuring they are balanced to prevent vibration․ Check for debris buildup under the deck, which can interfere with grass flow and cutting quality․ Inspect the deck levelness; an unlevel deck causes scalping․
Unusual noises during operation could stem from loose hardware – tighten all bolts and nuts on the deck and blade assembly․ Worn or damaged bearings in the blade spindles can also create noise․ Examine the belt tension; a loose belt may slip and cause a rattling sound․
Finally, ensure the tires are properly inflated, as uneven tire pressure affects deck stability․ Regularly cleaning the underside of the deck prevents buildup and maintains optimal performance․
Transmission Problems – Shifting Difficulties
Difficulty shifting gears on your Craftsman T140 often points to a low transmission fluid level․ Check the fluid level using the dipstick, and top off with the recommended transmission fluid type․ A worn or damaged shift cable can also hinder smooth shifting; inspect the cable for kinks or breaks․
Sticking gears may indicate internal transmission wear․ Avoid forcing the shifter, as this can cause further damage․ Ensure the engine is completely stopped before attempting to shift gears․ Inspect the linkage connecting the shifter to the transmission for proper adjustment and lubrication․
Regularly check and maintain proper belt tension within the transmission system․ If problems persist, professional servicing may be required to diagnose and repair internal transmission issues․
