Understanding Your Craftsman 7.25 Lawn Mower
Before diving into the starting process, it’s crucial to familiarize yourself with the different components of your Craftsman 7.25 lawn mower. This knowledge will help you troubleshoot any starting issues.
1. Identifying the Engine:
Most Craftsman 7.25 lawn mowers are powered by a Briggs & Stratton engine, but there are other possibilities. Refer to your owner’s manual or the engine itself to identify the specific model.
2. Locating the Fuel Tank and Controls:
- Fuel Tank: The fuel tank is typically located on the side or the top of the mower deck.
- Choke: The choke lever is usually found near the engine, often attached to the handle.
- Start Lever/Button: Depending on the model, you might have a lever or a button to start the engine.
- Throttle: This is typically found near the handle and controls the engine speed.
Starting Your Craftsman 7.25 Lawn Mower: Step-by-Step
Now, let’s get down to the business of starting your Craftsman 7.25 lawn mower. Follow these steps carefully:
1. Fuel Up:
- Check the fuel tank and ensure you have enough gasoline.
- Important: Always use fresh, clean gasoline for your mower. Old fuel can gum up the engine and cause starting problems.
2. Prepare the Engine:
- Choke: Engage the choke lever fully. This enriches the fuel-air mixture, making it easier for the engine to start.
- Priming: Some Craftsman 7.25 lawn mowers have a primer bulb. If your model does, gently squeeze it a few times to introduce fuel into the carburetor.
3. Starting the Engine:
- Lever/Button: Pull the start lever or press the start button.
- Important: On some models, the start lever may have a safety mechanism, such as a blade brake, which must be engaged before starting.
- Don’t Overdo It: If the engine doesn’t start after a few pulls, release the start lever and try again.
4. Disengage the Choke:
- Once the engine starts, gradually disengage the choke lever.
- Important: Allow the engine to warm up before engaging the throttle to full speed.
Troubleshooting Starting Issues
Despite following the steps above, you might still encounter problems starting your Craftsman 7.25 lawn mower. Here are some common issues and their solutions:
1. No Spark
- Symptom: The engine makes no noise at all when you try to start it.
- Solution: Check the spark plug. If it’s fouled or damaged, replace it. Make sure the spark plug wire is connected properly.
2. Lack of Fuel
- Symptom: The engine sputters and dies immediately.
- Solution: Ensure the fuel tank has enough gasoline. Check for a clogged fuel line or a faulty fuel filter.
3. Clogged Air Filter
- Symptom: The engine struggles to start and runs poorly.
- Solution: Clean or replace the air filter. A dirty filter restricts airflow, preventing proper combustion.
4. Battery Issues (For Electric-Start Models)
- Symptom: The starter doesn’t engage or the engine turns over slowly.
- Solution: Check the battery terminals for corrosion. If the battery is weak, recharge or replace it.
5. Engine Overheating

Frequently Asked Questions
What are the essential safety precautions I should take before starting my Craftsman 7.25 lawnmower?
Before starting your Craftsman 7.25 lawnmower, ensure you wear appropriate safety gear, including sturdy shoes, long pants, and safety glasses. It’s also crucial to inspect the area for any obstacles, such as rocks, debris, or toys, and clear them away to prevent accidents.
Furthermore, always disconnect the spark plug wire before performing any maintenance or repairs on the engine. This prevents accidental starts and potential injuries. Never operate the mower on steep inclines, as this can lead to loss of control and rollovers.
How do I check the fuel level and add fuel to my Craftsman 7.25 lawnmower?
To check the fuel level, locate the fuel tank, usually situated on the side of the mower. There’s a clear fuel gauge on the tank that will indicate the fuel level. If the fuel level is low, you’ll need to add gasoline.
Always use fresh, clean gasoline that’s recommended by the manufacturer. Never fill the tank to the brim, as this can lead to spillage. Ensure the fuel cap is securely closed after refueling to prevent leaks and spills.
What type of oil should I use for my Craftsman 7.25 lawnmower?
Use only the type of oil recommended in your Craftsman 7.25 lawnmower’s owner’s manual. This is crucial for proper engine lubrication and performance. Generally, SAE 30 oil is recommended for most lawnmowers, but check your manual for specific instructions.
Always use fresh oil and change it regularly as specified in the manual. Inspect the dipstick to ensure the oil level is within the appropriate range. Overfilling the engine with oil can cause damage and should be avoided.
How do I adjust the cutting height on my Craftsman 7.25 lawnmower?
The cutting height adjustment mechanism is typically located on the deck of the mower. It usually involves a lever or a series of knobs that control the height of the blades. Refer to your owner’s manual for specific instructions on how to adjust the height for your model.
Adjusting the cutting height is straightforward, but it’s important to understand the different height settings and their impact on the lawn. Higher settings will result in longer grass, while lower settings will provide a shorter, neater cut.
How do I start the Craftsman 7.25 lawnmower?
Starting a Craftsman 7.25 lawnmower is simple. Ensure the choke lever is in the “choke” position. Then, pull the starter cord slowly until you feel resistance. Once you feel resistance, pull the cord quickly and firmly. If the engine doesn’t start, repeat the process.
Once the engine starts, release the choke lever and let the engine idle for a few minutes to warm up. Always follow safety precautions like wearing safety glasses and clearing the area around the mower before starting.
What are some common problems I might encounter with my Craftsman 7.25 lawnmower?
Common problems include engine starting issues, poor cutting performance, and clogging of the mower deck. Engine starting issues can be caused by a lack of fuel, a clogged air filter, or a faulty spark plug. Poor cutting performance can be caused by dull blades, improper cutting height, or a clogged mower deck.
To troubleshoot these issues, check the fuel level, inspect and clean the air filter, replace the spark plug if necessary, and sharpen or replace the blades. Regularly clean the mower deck to prevent clogging. Refer to the owner’s manual for detailed troubleshooting instructions.
What should I do with my Craftsman 7.25 lawnmower after I’m done using it?
Once you’ve finished mowing, allow the engine to cool down before performing any maintenance or storage. Remove any grass clippings or debris from the mower deck and clean the underside of the deck.
Empty the fuel tank, as gasoline can degrade over time. If you’re storing the mower for an extended period, it’s advisable to drain the engine oil and clean the spark plug. Refer to the owner’s manual for specific instructions on storing your mower properly.
