Snapper Lawnmowers: Troubleshooting Cutting Problems
Some common problems you might face with the Snapper lawnmower (riding and self-propelled included) include failure to cut straight, uneven cuts on the grass, and failure to cut at all. All these problems are completely fixable with rather easy solutions.
There are a few reasons why the Snapper riding lawnmower may not be cutting straight.
The more obvious reason is damaged or blunt blades. However, that is not the sole issue. Un-anticipated problems such as poorly inflated tires or a fast mowing speed can also result in non-straight cuts to the grass.
Another reason for this problem is unbalanced blades which could be due to incorrect installation. Further, vibrations in the blade can also mess up the cutting patterns. Following are the steps that you can perform by yourself to alleviate the problem.
Here are some easy fixes for the problems causing a non-straight cut. Follow these steps.
- Blade: Check the mower blades to see if they are blunt. Sharpen them for a cleaner and more precise cut. Further, check if the mower blades appear unbalanced or tilted. This could be due to a fault in installation. Take them out and reinstall them.
- Tire: Check if the lawnmower tires appear imbalanced. This could be due to a decrease in air pressure in one of them. Check for damages to the tire and inflate them to the level instructed in the manual.
- Belt: To eliminate vibrations in the mower blade, check the belt for damages and repair or replace it. Additionally, check the mower deck for missing bolts, causing an imbalance.
- Mowing speed: If your mowing speed is too fast, slow down a little.
If you notice the lawn mower cutting uneven or jagged grass patterns, there could be issues with the mower deck, the blades, and even the tire inflation. The mower deck is likely damaged or clogged with grass debris which prevents clear cuts.
Similarly, uneven tire pressure in the lawn mower tires makes them unbalanced, causing uneven cuts. And it is no surprise that damaged, bent, blunt, or loose blades are the prime cause of uneven cuts.
Sometimes, the mowing speed can also cause uneven cuts. If you are mowing too fast or too slow, it will result in bad cuts. The cutting height is also an issue that sometimes prevents uniform cuts to the grass.
The problems may seem like a lot. However, they are likely to not all occur at the same time. Still, it is best to do a thorough inspection.
- Blade: Firstly, inspect the mower blades. Check to see if they are blunt, loose, bent, or damaged. You will need to sharpen them or tighten them. However, significant damage would mean a complete replacement is needed. Check that the mower blade is not tilted. If that is the case, remove it and reinstall it.
- Mower deck: Inspect the mower deck and shell for damages. If it is dented or breaking, you will need to clean it. If debris clogs the deck, scrape it off and clean it thoroughly.
- Tire: Uneven tire pressure can cause the mower deck to have an uneven height. Check all the tires and inflate them to the same height as instructed in the mower manual.
- Mowing Speed: Take a look at the manual for accurate mowing speed. Make sure you are not mowing too fast or too slow. Although some recommend running the engine at full throttle for precise cuts, that may not be ideal if your terrain isn’t perfectly level and has pits and bumps.
- Cutting height: Check the cutting height. Adjust it to the mark recommended in the manual.
If the lawnmower is functioning well but not cutting grass at all, the problem lies with the mower blades. Likely, the mower blades are not turning to cut grass.
This can be because the blades are likely installed wrong, that is, upside down. Since they are designed to turn in only one direction, the wrong installation will prevent them from turning correctly and cutting grass.
- Turn it over: Tilt the mower to inspect the blade. Make sure that the carburetor side is facing to prevent oil spillage.
- Remove the blades: Remove the blades and check which side should face up or down when installing. This is usually marked on the blades. Typically, mower blades have a curve that points toward the mowing deck when properly installed.
- Reinstall them: Install the blades correctly and try mowing again to see if the blades work.
A couple of drive problems can come up over time as you continue to use the lawnmower. Here are some common drive problems you may experience with the Snapper lawn mower.
One human error in why your lawnmower is not moving forward could be that the parking brake is engaged. The parking brake prevents the lawnmower from moving forward. Additionally, the drive belt can also be an issue. The drive belt transfers power from the engine to the wheels. If that is damaged or broken, the mower won’t go forward.
Another possible issue is a stuck brake or clutch. The mower will not move forward if these two haven’t fully disengaged. The mower will likely remain in the same position. Besides that, issues with the tire pressure, such as deflated tires, will also prevent the lawnmower from moving forward.
- Parking brake: Check if the parking brake is engaged. Make sure to disengage the brake before trying to move the mower.
- Drive belt: Check the drive belt for any wear and tear or bigger damages. If it’s loose, tighten it, and if the damage is too big, replace the belt to get the mower moving forward.
- Brake or clutch: If the brake or clutch is stuck, you should try lubricating them. This will allow them to disengage so the mower can move forward.
- Tires: Inspect the tire for damages or deflation. Repair the damages or replace the tires before inflating them again. Refer to the manual for accurate pressure.
Excessive vibrations in the lawnmower indicate several issues that could be the cause. To begin, unbalanced blades are one culprit. If the blades are bent, damaged, or improperly installed, they will create an imbalance that results in vibrations.
The belts driving the lawnmower blades and transmission can become worn out, loose, or damaged with time. The lack of tension in damaged belts causes vibrations in the lawnmower. Further, obstacles while mowing can cause damage to the mower deck. A bent or damaged deck will also create vibrations in the lawnmower.
Sometimes the issue can be with the engine mounts. The mower engine is mounted on a frame, and if the mounts become loose, the engine will vibrate excessively. This causes the entire mower to shake.
The vibrations in your lawnmower can go away in just a few easy steps:
- Mower blade: Check the mower blades for any visible damages. Replace them if needed. If the mower blades appear unbalanced, remove them and reinstall them.
- Drive belt: Inspect the drive belt for wear and tear. If it is loose, adjusting it will solve the issue. Otherwise, you will need to replace it in case of extensive damage.
- Mower deck: Inspect the mower deck for missing bolts or screws. Look for any dents, warps, or broken parts. Replace the mower deck if the damages are significant.
- Engine mounts: Check to see if the engine mounts or missing or loose. Replace or tighten them if necessary.
The lawnmower comprises certain steering components that can wear out over time, resulting in loose steering. In addition, improper wheel alignment, or positioning of the wheels, can also be the cause of loose steering.
Also, insufficient lubrication of the steering system can also cause loose steering. Finally, damage to the steering linkage, which connects the various steering components, can also cause loose steering in the lawnmower.
- Steering components: Inspect the different steering components, such as the steering wheel, tie rods, and steering shaft. Tighten or replace them if they seem worn out.
- Wheel alignment: Check the alignment of the front steering wheels and compare them to the alignment mentioned in the manufacturer’s manual. Adjust them if they are misaligned.
- Lubricate: Make sure no steering component is dried up, and lubricate them timely. You can check for the lubrication points in the manual.
- Steering linkage: Inspect the steering linkage and clean it thoroughly if debris or dirt is lodged in it. Finally, replace any worn-out or damaged parts to restore the steering function.
During its usage, a lawnmower’s tires come into contact with many obstacles and sharp objects. These objects can puncture these tires, causing them to lose air pressure and become flat. However, this issue is not difficult to resolve.
- Find a pressure gauge and inspect the tire pressure.
- Look for visible damages on the tires, such as scratches, tear marks, etc.
- Remove the damaged wheel and fix/patch the areas that are causing air to leak out.
- If the damage is big, you should replace the tire.
- Use an air compressor to pump air into the tire.
- Refer to the manual for the recommended amount of pressure.
If the lawnmower leaks oil, the damaged parts must be addressed urgently. A few common reasons can cause lawnmower oil leaks.
Frequently, overfilling the reservoir can cause an oil leak. Another common cause is worn or damaged gaskets. Gaskets are seals that prevent oil leaks from the crankcase of an engine.
Another reason could be a loose or faulty oil drain plug, responsible for draining oil during maintenance. Lastly, a cracked or damaged oil pan can also lead to oil leakage.
- Oil reservoir: When refilling the oil in the lawn mower, ensure it is filled to the 3/4th level and not overflowing.
- Leak area: Find where the lawnmower leaks and drain all oil from the mower. Store it somewhere for later use.
- Drain plug, gaskets, and oil pan: Fix or replace the damaged components, such as a worn-out drain plug, damaged gaskets, or a cracked oil pan.
Drive problems can also arise in Self-propelled lawnmowers. Issues include the inability of the lawnmower to move forward or problems with the throttle. However, there are some easy-to-perform fixes for these issues.
1. Lawnmower doesn’t go forward?
Your self-propelled lawnmower is not moving forward because of a broken or damaged drive belt that connects the engine to the transmission. Additionally, damages to the drive control cable mean the drive cable can’t engage the drive system, and the lawnmower won’t move forward.
Another issue can be clogged wheel axles. Any obstructions or damages to these will prevent the mower from moving forward.
- Drive belt: If the drive belt is broken or damaged, it must be replaced. To access the belt, you need to tilt the lawnmower and remove the mowing deck.
- Drive control cable: To fix the issues with the drive control cable, check if it is loose or damaged. Tighten any loose connections and adjust the cable tension. If the cable is beyond repair, you will have to replace it.
- Wheels: Inspect the wheels for clogged dirt or debris. Thoroughly clean them for better function. It helps to give them a routine clean now and then and ensure that the machine cuts and runs smoothly.
Many people don’t think of the carburetor when the throttle stops working. Debris and dirt can get lodged into the mower’s carburetor over time, causing it to interfere with the throttle’s function.
A more common issue is with the throttle cable, which is either loose or damaged, consequently failing to engage the throttle correctly.
- Carburetor: First, check the carburetor for dirt and debris. Thoroughly clean it and check the throttle function again. A clogged carburetor prevents the air-fuel flow to the engine; hence, the throttle cable becomes ineffective.
- Throttle Cable: Inspect the throttle cable for damages. In case of excessive wear and tear and lack of tension in the cable, replace the cable. If the throttle cable is in good shape, check if it is loose and can be tightened.
