The recommended oil type for the Simplicity 2690421 Conquest Tractor is SAE 30 for temperatures above 32°F (0°C) and 10W-30 for temperatures below 32°F (0°C).
To change the drive belt, first disconnect the spark plug, remove the mower deck, release belt tension by moving the idler pulley, and then replace the old belt with a new one following the belt routing diagram.
If the tractor won't start, check the battery charge, ensure the fuel valve is open, inspect the spark plug for damage, and verify that the safety switches are engaged properly.
It is recommended to perform maintenance every 25 hours of operation or at the start of each season, including oil changes, air filter cleaning, and checking tire pressure.
To store the tractor, clean it thoroughly, change the oil, drain the fuel or add fuel stabilizer, and store it in a dry, covered location. Disconnect the battery if storing for an extended period.
For uneven cutting, check the tire pressure, ensure the mower deck is level, inspect the blades for sharpness and damage, and adjust the cutting height as needed.
If the tractor is overheating, check for debris blocking the air intake, ensure the cooling fins are clean, verify the oil level, and make sure the engine is not overloaded.
To replace the air filter, locate the air filter housing, remove the cover, take out the old filter, and install a new one ensuring it is seated properly before replacing the cover.
If the transmission is not engaging, check the transmission fluid level, inspect the drive belt and linkage for wear or damage, and ensure the shift lever is properly adjusted.
To improve fuel efficiency, keep the engine properly tuned, maintain correct tire pressure, use the recommended oil type, and avoid overloading the tractor.
