How to Tighten a Drive Belt on a Craftsman Riding Lawnmower, step by step
Ever witnessed your Craftsman lawnmower not mowing properly or leaving patches of uncut grass? A loose drive belt might be the very reason. Luckily, the entire process is relatively easy, and all you’ll need for the adjustment is just a socket wrench. If you’ve never performed self-maintenance on your Craftsman lawnmower before, then don’t worry as we dissect this information for you in a step-by-step approach.
How to tighten a drive belt on a Craftsman riding lawnmower, step by step:
- Step 1: Test thetension in your existing lawnmower drive belt
- Step 2: Inspect the components on the mower such as the pulleys, belt, spring, and swingarm and check for any damage
- Step 3: Pull back the clamp holding the cable and tighten it so that the spring attached to it is stretched
- Step 4: Start the engine and engage the blade lever to check for the belt operation after adjustment
Drive belts are components that connect the engine’s transmission shaft to the transaxle pulley and are responsible for the transmission of torque and power to the blades. It is situated underneath the mowing deck in case of riding lawnmowers.
The belts usually wear out after continued use. Due to elongation in their tensile cords, drive belts have been known to become loose with time. Most often, the remedy is a replacement. However, in cases when elongation isn’t much, you can always adjust the belt tension, and we are looking at that in this article.
The article covers all the steps needed to tighten the drive belt in case of your Craftsman lawnmower. I will also provide a brief overview of some frequently asked questions regarding drive belts and lawnmowers. Stay tuned.
Troubleshooting and Adjusting the Drive Belt on a Craftsman Riding Lawnmower, step-by-step:
The steps that need to be followed for fixing the Craftsman lawnmower drive-belt are mentioned below:
Step 1: Test current drive belt for operation:
Before we dig into it, we first need to see whether the current drive belt is worth tightening or not. Most Craftsman models have a blade engagement lever next to the steering wheel. After the cutting deck is lowered to the ground, the lever engages the blades to make contact with the grass and perform their function.
To see if your current drive belt is loose or not, start your engine and push your throttle lever to the highest. Next, engage the cutting blades by pushing the lever upwards. If you hear the blades’ cutting sound right after you push the engagement lever, it indicates that the drive belt has the requisite tension in it and doesn’t need any adjustment.
If you notice that the blades aren’t cutting the grass after the very instant you push the lever and give a whirring sound, it means that your drive belt is slipping, thus pointing out the need for adjustment or replacement.
Step 2: Inspect the mower deck components:
As we’ve seen, the drive belt is slipping; we need to troubleshoot this for the components located on the mower deck. To do this, lower the deck as much as you can and pull back your blade engagement lever. Then, you need to inspect the following components:
Belt: Make sure that your drive belt is intact and doesn’t appear damaged with chunks missing and cracks. If it seems damaged, then you should replace it right away.
Swingarm: The swingarm is a component on the deck where the springs are connected, and a pulley is mounted. The arm is pivoted at one end and free to rotate at the other end. Make sure that the arm is free to rotate. If it is not, drop some oil or a lubricant at the pivoted end, which might have been jammed.
After the above components are functioning correctly, push the lever again to engage the blades.
Spring: The cable that comes from the lever is connected to a spring. Touch the spring to see if it’s completely stretched or loose. Also, touch your belt at the same time and notice if it appears loose. If it does, we shall move on to the next step, adjusting the belt tension.
Step 3: Tighten the belt by adjusting the cable:
After you’ve seen your belt loosened up, disengage the blade lever again. You would have noticed the wire that comes from the blade lever and is attached to the springs. On the deck, it is mounted on a bracket.
Loosen the bolts on the bracket is push it back in the direction away from the spring. You now feel that the spring is tightened up.
Step 4: Test the belt for tension:
After the bracket has been pulled back, start your lawnmower engine at full throttle. Now, push the blade engagement lever upwards and immediately notice the cutting action of the blades. If the blades begin cutting without delay, it means that the belt tension is now optimal. However, If the belt still seems loose enough, it indicates that this method didn’t add the required tension, and therefore you should think about replacing the belt.

How to remove and replace the drive belt on a riding lawnmower?
In most cases, tightening the drive belt does not solve the problem, and you often need to replace it altogether with an identical one. The steps for doing that are listed below:
Step 1: Disconnect the spark plug
First, you should turn off the ignition switch and remove the key. Next, you need to pull the mower hood upwards and disconnect the spark plug wire.
Step 2: Disassemble the mower deck
Next, you need to disconnect the entire mower deck from the main body of the lawnmower.

– Step 2.1: Lower the mower deck
As a first step, lower the mower deck on the ground to the lowest position and disengage the blades.
– Step 2.2: Roll the belt off
Roll the belt off the engine pulley and release the belt keepers.
– Step 2.3: Detach the deck
Now, you need to remove all the linkages that connect the mower deck to the upper portion from both sides of the mower deck. To do this, remove the retaining pins and washer supports from the lift link, suspension arm, and rear end bracket on both the left and sides of the mower deck. The deck should now be detached completely.
– Step 3.1: Take a picture
Note the routing of the blade belt on the mower deck. We recommend taking a picture to record the layout.
– Step 3.2: Remove the old belt
You might see three pulleys on the deck, namely one idler pulley along with belt keepers and two mandrel pulleys. Remove the old drive belt from the three pulleys.
Step 4: Install the new belt
Loop the new drive belt around the mandrel pulleys and pass it around the idler pulley through the belt keeper. Push the deck back under the mower.
Step 5: Reconnect the mower deck
Reconnect all the removed links such as the lift links, suspension arms, and rear end bracket back onto the mower deck through the retaining pins and washers. Attach the belt back to the engine pulley.
With the mower deck assembled, reconnect the spark plug wire and insert the key in the switch. Start your mower and test the new belt for performance.
How long is the drive belt on a Craftsman riding lawnmower?
Drive belts are responsible for transferring power from the engine pulley to movable parts in the mower, such as the blades. Craftsman lawnmower models consist of primary and secondary drive belts. Both belts have a length ranging from 42-55 inches depending on the particular model.
Why does the belt keep slipping off the lawnmower?
The drive belt of your lawnmower may come off for various reasons. The exact reasons may depend on the design of your machine. However, some general reasons resulting in this problem are listed below:
– Damaged parts:
The drive belts and idler pulleys may affect the belt operation if they are not in working condition. over, the swing arm should be able to rotate freely about its pivot. You need to check the mower deck’s adjustment as well. For normal conditions, the deck’s front is generally lower 1/8 to 1/4 inches than the back. A pitch greater than this may cause the belt to keep slipping off.
– Debris Buildup:
The buildup of dirt and dust between the pulley and bracket may also reduce the friction attaching the belt onto the pulley. Make sure that no soil, grass, or sticks are found along the drive belt. This condition is quite imminent under rough operating conditions and low maintenance.
What are the two significant forms of drive belts used?
Transmission belts in machine design may be of the V-type or synchronous design. V-belts have a wedge-shaped cross-section. Friction is the only force keeping the belt attached. On the other hand, synchronous belts have a notched profile along their inner circumference, much like gears. They are generally mounted on gears and pinions and are used in timing operations.
Craftsman lawn tractor drive belt problems
If you want to replace the drive belt in your Craftsman lawn tractor, but do not know how to, use the following tips:
- Make a short video or take some pictures before removing the old belt.
- Ensure that you use the correct belt. You can use the model number that is often under the seat for this.
- Check the idler tensioner springs and brake arms, and replace them when needed.
If the belt was damaged and it is gone, you can not find any information on how the belt should be routed. Use the following to understand where the belt needs to go:
- Most Craftsman lawn tractors have up to 5 pulleys for the drive belt. They are easy to recognize.
- The pulley underneath the engine is the drive pulley.
- The pulley above the blades is easy to find. There can be 1 or two.
- Generally, there is one spring-loaded pulley, that keeps the belt under tension. In some models, there is no spring-loaded pulley, but they can be moved to tension the belt.
- The remaining pulleys are fixed pullies that take care that the belt is running around other objects.
Craftsman Belt Keeps Coming Off or Breaking
Generally, a craftsman belt can keep coming off due to several reasons:
- Check for debris: Check the underside of the lawnmower for any debris that may lead to the belt coming off.
- Damaged or stretched belt: When the belt is damaged or stretched it will become loose. A little bit of extra tension will be compensated by the tensioner, but if it loosens too much it will quickly come off. If the belt is damaged or stretched, it needs to be replaced. If you notice that the belt is slippery, maybe due to oil, clean it.
- Damaged pulley bearings: If the bearings from one or more pulleys or from the spindle housing get damaged, it can result in too much slack for the belt. Check the different pulleys for movement, and replace the pulleys.
- Belt keeper: If your Craftsman lawnmower uses a belt keeper next to the pulley, it may be bent or damaged. In that case, it may be the reason why the belt keeps coming off.
- Dirty pulleys: The different pulleys have a groove that keeps the belt in the correct location. If those grooves contain dirt, it can lead to the belt coming off. Check and clean the pulleys.
- Tension spring: The belt is kept at the correct tension with the tension spring. If the spring gets worn out, it may not do its job correctly. Check the tension bracket and spring. If the spring and bracket look ok, check if they can move freely. If not, grease all the moving parts. Replace the spring and bracket if damaged or the spring is worn out too much.
- Wrong belt: Ensure that you use the correct belt for your Craftsman Lawnmower. The wrong belt, even if it may look fine, can result in coming off easily.

Lawnmower belt maintenance may be one of the most frequently occurring instances, mainly if the mower hasn’t been well maintained in the past. We recommend cleaning your lawnmower occasionally and adequately checking the mower deck working components to see if they are in proper working order. Furthermore, you should always consult the owner’s manual when making a belt replacement. It is better to exercise caution while making these replacements to don’t end up accidentally starting your lawnmower.
How To Tighten Drive Belt On Craftsman Self-Propelled Lawnmower
If you’re looking to make a few changes to your lawnmower, ensure the drive belt is adjusted correctly. The loose belt may cause vibration, making it harder to control the mower.
The drive belt should be tightened at all times, especially if the mower is trailer-mounted or has a more independent structure.
This prevents the belt from tangling up in the gears and prevents it from moving freely between driving and stop positions during significant acceleration or deceleration.
How to tighten drive belt on craftsman self-propelled lawnmower
A loose drive belt is one of the most common reasons a self-propelled lawn mower will quit working. The tricky part about finding the right replacement belt is that many parts houses will offer extended warranties on their product only to cover manufacturing defects.
This means if you purchase a defective part, you could be on the hook for thousands of dollars without ever receiving a replacement, hence you can buy a self-propelled lawn mower under 400.
To avoid this unfortunate situation, always conduct your research and speak with a dealer or manufacturer before beginning maintenance projects. Here are well-detailed steps you can follow to tighten your drive belt.
Testing current test drive
The easiest way to check the drive belt tension is with an adjustable wrench. Loosen the set screw and turn the wrench counter-clockwise to adjust the drive belt on a lawn mower.
Use a torque wrench on more giant diameter belts. However, many newer belt tension devices are explicitly designed with smaller diameters and small ground stakes.
When using a torque wrench, paying close attention to blade tension is essential, as this can easily make or break a lawnmower operation.
Checking the mower deck components
The first thing to look at when troubleshooting a slipping drive belt is the entire drive belt assembly. If anything, wrong with it, it could be the difference between keeping the ride smooth or ending with a rough ride.
Inspecting the entire unit will allow you to see what material is being used, which helps determine if it’s old or new.
Of course, the best way to know is by looking at the engine bay for any signs of worn threads or cracks that may imply there are problems with the belt.
Belt– The belt on a mower is one of the most critical components to ensure proper steering and handling. Rust or mildew can easily ruin the tension on this belt, growing on it.
Inspect the drive of the belt itself for wear and make sure that it’s not rickety or poorly made. An adequately installed belt will hold the mower steady during rough riding conditions without creating additional damage to the drivetrain.
Swingarm– The first thing to inspect is the swingarm and the bearings. Scrutinize these for wear, scratching, or damage. Next, scrutinize the swingarm for cracks or other damage. If there are any issues with the swing arm at all, it will need to be replaced.
Finally, inspect both ends of the frame for cracks or other damage. If any of these issues cause the mower not to function as expected, it will need to be removed and professionally rebuilt.
Spring– The belt’s tension is another critical tube that allows the mower to kick back in high gear. If the belt has too much slack, the kickback will be uneven, eventually pulling the right part of the blade away from you towards the target.
If too much tension is put on the spring, though, it can snap back when you stop moving it—damaging the cable or pulling out teeth on the lever. If the tension on either of these two parts is too much, you may end up in a dangerous situation where the blade moves toward you without you being able to stop it – which could cause severe injury or even death.
Adjust the cable to tighten the belt
If the belt tension has become tight after a few uses, it shows that the tension cable is damaged. If this hurts the belt, then you will have to replace it. Replace the belt with another one which is made from high-quality material.
To tighten the drive belt on a self- propelled lawn mower, to keep working, you must use the blade lever to apply pressure on the belt, which will tighten up the sash. Whoever wants to work with a belt has to learn how to control it properly.
Keep in mind; this is not just a matter of feeling good about yourself—although that makes a difference! It is also necessary to know how the belt will react in different circumstances:
If you apply too much pressure at once or without raising the belt all the way, it cannot tighten as much as it would with less force. Therefore, using a screwdriver or vice versa is potentially dangerous when working around power tools.
The purpose of the drive belt should be to provide sufficient tension for the grass cutter to work well. Tighten the drive belt on a self-propelled lawn mower several times while mowing the lawn, but this depends on how much grass is on the blades, how often you will use the mower on uneven ground, and so on.
Adjust the drive belt on a lawn mower accordingly. A properly adjusted belt will not only make it easier for you to use the machine for more extended periods without getting sore or tired, but it will also save you from pulling on unnecessary grass sections that could eventually cause dents or damage to the blades if they are excessively pushed onto.
FAQs
How do you tighten the belt on a Craftsman lawn mower?
Keep your Craftsman lawn mower in tip-top shape by regularly replacing belts and cleaning components like the chain, tension cables, and lower driving handle assembly.
These easy-to-replace parts will keep the tension on the drive belt and help prevent flats or spins on uneven ground. Drive belt tension is essential, as it helps disperse the engine’s power between the front and rear wheels during acceleration and deceleration.

Will pushing self-propelled mower damage it?
It is possible to push a self-propelled lawnmower with some practice. However, it takes a lot of determination and care. As the pushing begins, check both the steering and throttle operation.
The power should be applied gradually until the ability is well-developed. Care should be taken with the brakes, as they may not handle the sustained speed required.
Do Lawnmower belts shrink?
Lawnmower belts shrink mainly when the right size is not used. For example, a long or short belt can cause belt shrinking. Also, some belts may shrink depending on their make due to stickiness when used as automotive belts.
Conclusion
It is easy to tighten the drive belt on a craftsman self-propelled lawnmower. But you know the difference between a regular drive belt and an extended one. The basic manual mower only has a primary control installed.
A drive belt comprises several parts that adjust and couple together to provide maximum power to the wheels and feet. An extended belt will often have additional movement parts that couple together to provide extra tension on the belt.
The pressure created will allow you to turn the mower either side-to-side or up and down without having to pull on the handle, especially with more extensive or heavier grass clippings in the area.
