Poulan Pro RT900 Operator's Manual

To start the Poulan Pro RT900 Tiller, ensure the fuel tank is filled with fresh gasoline. Set the choke lever to the 'start' position, pull the starter rope slowly until resistance is felt, then pull quickly. Once the engine starts, gradually move the choke lever to the 'run' position.
The recommended maintenance schedule includes checking the oil level before each use, changing the oil every 25 hours of operation, cleaning the air filter after every 10 hours, and inspecting the tines and drive belt for wear and damage regularly.
If the tiller won't start, check for fuel in the tank, ensure the spark plug is clean and properly gapped, examine the fuel line for blockages, and verify that the air filter is clean. If these steps don't work, inspect the ignition system and carburetor for issues.
To store the tiller, clean it thoroughly, drain the fuel tank or add a fuel stabilizer, change the oil, and store it in a dry, sheltered location. It's also advisable to remove the spark plug and add a small amount of oil into the cylinder to prevent rust.
If the tines are not rotating, first check the tine engagement lever to ensure it is in the correct position. Inspect the drive belt for wear or breakage, and check that the tine shaft is not obstructed by debris. Replace any damaged parts as necessary.
To adjust the tilling depth, use the depth stake at the rear of the tiller. Raise the stake for deeper tilling or lower it for shallower tilling. Ensure the adjustment is secure before operating the tiller.
The Poulan Pro RT900 Tiller engine typically requires SAE 30 oil for temperatures above 40°F (4°C) and SAE 10W-30 for temperatures below 40°F (4°C). Always check the manufacturer’s manual for specific recommendations.
To reduce vibration, ensure all nuts and bolts are tight, the tines are not damaged, and the engine is running smoothly. Balancing the tiller on flat ground and adjusting the handle height for comfort can also help minimize vibration.
If the tiller is leaking oil, check for visible cracks or damage in the engine block, inspect seals and gaskets for wear, and ensure the oil drain plug is tight. Replace any damaged components and refill with the proper oil level.
To change the spark plug, disconnect the spark plug wire, use a spark plug socket to remove the old plug, and check the gap on the new spark plug. Install the new spark plug hand-tight, then tighten it with a socket wrench. Reattach the spark plug wire.
