To start the Simplicity 7100 Series Tractor, ensure the parking brake is engaged, shift to neutral, adjust the throttle to the middle position, and turn the ignition key clockwise until the engine starts.
It is recommended to use SAE 30 oil for temperatures above 32°F (0°C) and SAE 5W-30 oil for temperatures below 32°F (0°C).
Routine maintenance includes checking and changing the oil, replacing the air filter, inspecting belts, cleaning the deck, and lubricating moving parts as specified in the user manual.
Check the battery connections, ensure there is fuel in the tank, verify the spark plug is functional, and make sure the safety switches are engaged.
To adjust the cutting height, use the lever located near the driver's seat to select the desired cutting position. The height can usually be adjusted between 1.5 to 4 inches.
Refer to the manufacturer's specifications in the user manual, but typically, the front tires should be inflated to 14 PSI and the rear tires to 10 PSI.
Ensure the mower deck is level, check for worn or bent blades, and make sure the tire pressure is consistent on all tires.
Clean the tractor thoroughly, change the oil, add a fuel stabilizer, disconnect the battery, and store it in a dry, sheltered location.
Check the drive belt for wear or damage, ensure the transmission fluid is at the correct level, and inspect the linkage for any misalignment.
To replace the blades, ensure the tractor is off and secure, lift the deck, remove the blade bolts, and replace with new blades, ensuring they are properly aligned and tightened.
