This article is designed to empower you with the knowledge to confidently start and maintain your Toro 721E snowblower. We will delve into the specific steps for a successful startup, explore preventative maintenance practices to prolong its lifespan, and offer solutions for those occasional hiccups. By the end of this guide, you'll be well-equipped to face any snow event with your Toro 721E performing at its best.
Pre-Start Checks: Setting the Stage for Success
Before you even think about pulling the starter cord, a thorough pre-start check is crucial for both safety and optimal performance of your Toro 721E. Begin by inspecting the overall condition of the snowblower. Look for any loose parts, damaged components, or debris that might have accumulated during storage. Ensure all safety guards are in place and securely fastened. This initial visual inspection can prevent potential hazards and costly repairs down the line.
Next, focus on the fuel and oil levels. For the Toro 721E, it's essential to use fresh, unleaded gasoline. Stale fuel can lead to starting problems and engine damage. Check the fuel tank and fill it to the recommended level, but avoid overfilling. Similarly, verify the engine oil level using the dipstick. If it's low, add the correct type and weight of oil as specified in your owner's manual. Proper lubrication is vital for engine longevity and smooth operation.
Finally, examine the auger and impeller. Ensure there are no obstructions like rocks, sticks, or ice lodged in the auger housing or the impeller. Clear any debris carefully. Also, check the shear pins, which are designed to break if the auger encounters a solid object, protecting the engine. Make sure they are intact and properly seated. A quick check of the tires for proper inflation can also contribute to easier maneuverability.
The Starting Sequence: Bringing Your Toro 721E to Life
With your pre-start checks complete, you're ready for the actual starting sequence of your Toro 721E. First, ensure the snowblower is on a level, stable surface. Locate the choke lever, typically found on the control panel. For a cold engine, you'll want to engage the choke fully. This enriches the fuel-air mixture, making it easier for the engine to ignite.
Next, prime the engine by pressing the primer bulb located near the carburetor. You'll usually need to press this bulb three to five times, or until you see fuel filling the bulb. This action pushes fuel directly into the carburetor, aiding in the initial combustion process. Once primed, move the choke lever to the "run" or "start" position, depending on your model's specific markings.
Now, grasp the starter rope handle firmly and pull it with a steady, strong motion. Avoid yanking or jerky movements. You may need to pull the rope several times. Once the engine begins to sputter or run briefly, you can gradually move the choke lever to the "run" position. This allows the engine to receive a leaner fuel mixture as it warms up. If the engine stalls, you may need to repeat the priming and starting process.
Essential Maintenance for Longevity and Performance
Regular maintenance is the cornerstone of a long-lasting and reliably performing Toro 721E snowblower. After each use, it's good practice to clear away any accumulated snow and ice from the auger, impeller, and discharge chute. This prevents ice buildup and potential corrosion. A quick wipe-down of the exterior can also keep your snowblower looking its best and prevent rust.
At the beginning and end of each snow season, a more thorough maintenance routine is recommended. This includes changing the engine oil. Refer to your owner's manual for the correct oil type and capacity. Inspecting and cleaning or replacing the spark plug is also vital for efficient combustion. A fouled spark plug can lead to hard starting and poor engine performance.
The air filter is another component that requires attention. A clogged air filter restricts airflow to the engine, reducing power and efficiency. Inspect it regularly and clean or replace it as needed. For the Toro 721E, checking the drive belts for wear and tension is also important. Worn belts can slip, affecting the auger and wheel drive. Finally, lubricating moving parts, such as the auger bearings and control cables, will ensure smooth operation and prevent seizing.
Troubleshooting Common Starting Issues
Even with proper maintenance, you might occasionally encounter starting problems with your Toro 721E. One of the most common culprits is stale fuel. If your snowblower has been sitting for an extended period with old gasoline, it can gum up the carburetor and prevent ignition. In such cases, draining the old fuel and refilling with fresh gasoline is often the solution.
Another frequent issue is a dirty or fouled spark plug. If the engine is getting fuel but not firing, remove the spark plug, inspect it for carbon buildup or damage, and clean or replace it. Ensure the gap is set correctly according to your owner's manual. A blocked fuel line or a dirty fuel filter can also impede fuel flow to the engine.
If the engine cranks but doesn't start, check the choke operation. Ensure it's engaging properly for a cold start and that you're gradually moving it to the run position as the engine warms. Sometimes, a simple obstruction in the auger or impeller, even if not immediately apparent, can cause the engine to seize or refuse to start. A thorough inspection of these areas is always warranted.
Safety First: Operating Your Toro 721E Responsibly
Operating any snowblower, including the Toro 721E, requires a strong emphasis on safety. Always read and understand your owner's manual before operating the machine. Wear appropriate clothing that is warm but not so loose that it could get caught in moving parts. Sturdy, non-slip footwear is essential for maintaining balance on icy surfaces.
Before starting, ensure the area you intend to clear is free of obstacles such as rocks, branches, toys, or electrical cords. These can be thrown by the auger at high speeds, causing damage or injury. Never operate the snowblower in a confined space where exhaust fumes can accumulate, as carbon monoxide poisoning is a serious risk.
When the snowblower is running, keep your hands and feet away from all moving parts, especially the auger and impeller. Never attempt to clear a clog while the engine is running. Always turn off the engine and wait for all moving parts to stop completely before attempting to clear any obstructions. If you need to adjust the chute direction, do so only when the engine is off.

Frequently Asked Questions
How often should I change the oil in my Toro 721E?
It is generally recommended to change the engine oil in your Toro 721E at least once per snow season, typically at the beginning or end. Refer to your owner's manual for the specific oil type and capacity, and follow the manufacturer's guidelines for oil change intervals based on operating hours if you use it extensively.
What type of gasoline should I use in my Toro 721E?
Your Toro 721E is designed to run on fresh, unleaded gasoline with an octane rating of 87 or higher. It is crucial to use fresh fuel, as gasoline can degrade over time, leading to starting problems and engine performance issues. Avoid using E10 or higher ethanol blends if possible, as they can be harsher on fuel system components.
My Toro 721E is hard to start. What could be the problem?
Hard starting can be caused by several factors. First, ensure you are using fresh fuel and that the primer bulb is being pressed correctly. Check that the choke is engaged for a cold start. If it still struggles, inspect the spark plug for fouling or damage and clean or replace it. Also, ensure the air filter is clean and that there are no obstructions in the fuel lines or carburetor.
How do I clear a clog in the auger of my Toro 721E?
To clear a clog in the auger of your Toro 721E, always turn off the engine and wait for all moving parts to stop completely. Use a clearing tool, such as a stick or a dedicated auger cleaning tool, to carefully dislodge the obstruction. Never use your hands or feet to clear a clog while the engine is running or could potentially restart.
What is the purpose of the shear pins on my Toro 721E?
The shear pins on your Toro 721E are safety devices designed to protect the auger and engine from damage. If the auger encounters a solid object, such as a rock or a thick branch, the shear pins will break, allowing the auger to stop spinning while the engine continues to run. This prevents more severe damage to the gearbox and engine components.
