You’re left with one disheartening realization: your drive belt has snapped. This can happen to the best of us, leaving you with a seemingly unusable mower. But don’t worry! Replacing a drive belt is a fairly straightforward DIY task, and this guide will walk you through the process step-by-step. We’ll cover everything from identifying the right belt to the final reassembly, ensuring you can get your mower back in action quickly.
Overview
Replacing a drive belt on an Ariens lawn mower involves disassembling the mower deck, removing the old belt, installing the new one, and reassembling the deck. This process typically takes about 30 minutes, depending on your experience level and the specific model of Ariens mower you have.
Getting Started: Safety First and Tools Needed
Before you dive in, remember safety comes first. Always disconnect the spark plug wire from the spark plug to prevent accidental starting. Also, wear safety glasses and gloves to protect yourself.
Here’s what you’ll need:
- New drive belt: Ensure you get the correct size and type for your Ariens model. You can find the specifications in your owner’s manual or by contacting Ariens directly.
- Wrench set: You’ll need wrenches to loosen and tighten bolts.
- Screwdriver: A Phillips head screwdriver is often needed for removing and replacing screws.
- Pliers: Pliers can be helpful for gripping and removing parts.
- Work gloves: These will protect your hands while working with the mower.
Identifying the Drive Belt
The drive belt is usually located under the mower deck and connects the engine crankshaft to the mower blades. To find it, first, locate the engine and the mower blades. The belt will be the long, rubber band-like component that wraps around both.
Disassembling the Mower Deck
Remove the blade: Before you can access the drive belt, you’ll need to remove the mower blade. Use the wrench set to loosen and remove the blade bolt.
Remove the deck: Depending on your model, you might need to remove the entire mower deck or just a portion of it. Consult your owner’s manual for specific instructions.
Locate the drive belt: Once you have the deck partially or fully removed, you’ll see the drive belt. This is a good time to inspect the old belt for any signs of wear, fraying, or cracking. This will help you determine if it’s time to replace it.
Replacing the Drive Belt
Remove the old belt: Carefully remove the old drive belt by loosening the tensioner (if applicable) and sliding it off the pulleys.
Install the new belt: Position the new belt around the pulleys following the same path as the old belt.
Tighten the tensioner: (If your model has one). Once the new belt is in place, adjust the tensioner to ensure the belt is taut but not overly tight. Check your owner’s manual for the recommended tension.
Reassembling the Mower Deck
Attach the blade: Once the new belt is installed, re-attach the blade, ensuring the blade is securely tightened.
Replace the deck: Carefully reassemble the mower deck. Double-check all screws and bolts are securely tightened.
Reconnect the spark plug wire: After reassembling the deck, remember to reconnect the spark plug wire to the spark plug.
Testing the New Drive Belt
Start the engine: Turn the ignition key to start the engine.
Check for proper function: Once the engine is running, check that the mower blades are spinning at their normal speed.
Adjust tension if needed: If the blades are spinning too slowly or too quickly, adjust the belt tension (if your model has a tensioner) accordingly.
Maintenance Tips for Your Drive Belt
- Regular Inspections: Inspect your drive belt regularly for signs of wear and tear. This includes checking for cracks, fraying, or loose strands. Replace the belt if you see any of these signs.
- Proper Tension: A drive belt that is too loose can slip and cause damage. A belt that is too tight can put unnecessary strain on the engine and other components.
- Cleanliness: Keep the drive belt and surrounding areas clean and free of debris.
Troubleshooting Common Problems
If you encounter problems after replacing the drive belt, here are a few common issues and potential solutions:
- Belt slips: Check that the belt is properly tensioned and that there are no obstructions preventing it from moving freely.
- Blade doesn’t spin: Verify that the blade is securely attached and the spark plug wire is connected. You might also check if the blade is loose or bent.
- Engine overheats: Make sure the drive belt is not too tight, as this can put extra strain on the engine. Also, check the air filter for clogs and ensure proper cooling airflow.

Replacing a drive belt on your Ariens lawn mower is a simple repair that can save you time and money. By following these instructions, you can quickly get your mower back in working order and back to enjoying your yard.
Remember to prioritize safety, use the right tools, and refer to your owner’s manual for specific details on your Ariens model. With a little effort, you can keep your mower in top shape for years to come.
