Shafts and pulleys, especially on riding mowers made by Murray, let the blades know when the engine is turning. On a riding mower, there are only a few places where a problem with the mower’s ability to cut grass can be found.
Don’t worry if your mower isn’t cutting the grass well enough. You can try the nine simple fixes listed below on your lawnmower to try to fix any problems.
So let’s start fixing things so that your lawnmower can start cutting grass again the way it was meant to. So what?
Why Your Lawn Mower Might not be Cutting the Grass and How to Fix It
Most of the time, it’s because of a dull blade, but that’s not the only reason. What went wrong with your lawn mower, and how can you repair it?
Putting in a Blade the Wrong Way
Misplaced blades are most likely to cause your mower work inefficiently. Your mower won’t cut grass if the blades are not in the right place. The blades will turn correctly even if your mower’s blade is turned upside down. However, the edge of the blade that cuts the grass won’t be able to cut.
Change the blade in a manner that the beveled edge faces the direction in which the blades turn. You could easily avoid this from happening in the future if you put labels on the mower’s blades before taking them out. You now have a guide to help you put your mower blades back in place or change them out.
Problems with the Power Grid
Some lawn mowers have a clutch for power take-off that can connect or disconnect a drive pulley. It is done with the help of a solenoid and switches. If the solenoid, clutch, or switch wears out or stops working, the mower’s engine will start to run and move. However, the blades won’t work.
Check to see if the solenoid and switch still work, and replace any parts that are broken. If these equipment pass the tests of continuity, the clutch may be broken.
It’s possible that a frayed drive or worn-out chain has been stretched so far that it’s out of enough friction to move the pulleys. This happens whether the pulleys on a riding lawn mower are engaged by a grip or by mechanical means.
Replace drive belts that are broken or worn so that the pulleys can turn the blades once again.
Check to see if the Blades are Broken.
When cutting and gathering grass, a broken blade can cause a lot of trouble. Check your blade for damaged, bent, broken, or misaligned blade tips and any loose bolts.
Even if a blade looks like it’s in good shape, it will wear out over time. If it’s been used for more than four seasons, it’s probably no longer of use.
As a short-term fix, the blade needs to be changed. Put a new bolt and washer on the blade. They are treated and made for mowers in a special way, so bolts bought from the hardware store won’t work.
Torque wrenches can make sure that the bolt is tight enough. You can find the specifications by looking at your mower’s manual or the dealer’s website. Don’t try to fix or bend a blade because the metal has been treated and it could break if you do.
If you just put in a new blade, check to make sure it is facing the right way. A blade could have been put in backward. Don’t be afraid; even a Bishop could get hurt!
You can see the leading edge will move in a clockwise direction while looking down at the blade from above.
Replace: A new blade is the solution for a lot of problems. When you change the blade, you should also change the bolt and the washer.
The main reason why grass isn’t cut is a dull blade. The dull blade will quickly destroy your lawn because it breaks the grass while leaving a jagged edge. This makes the tips of the grass turn yellow.
You should sharpen your mower blade at least once a season. If you file your blade regularly, it is easy to keep it sharp. Grass that is green, lush, and healthy needs blades that are sharp.
Examine Engine Power
See if the throttle is fixed right; while cutting, it must be on fast or run. If you turn down the power of the engine, the mower won’t cut the grass well, especially if it comes across an area of thick grass.
No matter how they work, lawnmowers should be tuned up and the blades should be sharpened at the beginning of each season.
Change the oil in every 50 hours, and every twenty-five hours, or more often if you’re living in a dry, dusty conditions, the air filter should be changed. If your mower engine isn’t going as fast as it should, make sure the throttle can be used. Even if the lever is on full throttle, maybe the cable is not moving the end of the carburetor.
Then, check if the air filter. If it’s clean then, try to run the engine without its filter to see if anything changes.
Old gasoline is the main reason why an engine doesn’t work well. When fuel is a month old, it goes bad and clogs up the carburetor.
As a result, the ports where gasoline comes in are closed, leaving people without fuel. This slows down the engine and makes the yard look messy.
The Key Fell
A clutch system might be part of your tractor mower. The clutch gives the blades power from the engine. When the mower clutch starts to wear out, it slips, so the blades don’t spin with the very same speed or force as before. It will stand out more in taller, denser plants.
If there’s a separate switch to move the blade, you definitely have a clutch. Keep in mind that these hold systems are cable-operated, so in some walk-behind lawn mowers, you may only need to change the cable tension.
If you don’t have a grip point but can control the blades with another lever, you might be able to use a tightened belt to move them.
If lifting the bail lever’s work is to tighten the load on the belt as well as make the mower blades spin, it may just be that the belt tension needs to be changed.
Frequently Asked Question (FAQs)
Why won’t my mower’s blades cut?
First, make sure the pulleys are running well and are securely attached to the mower.
Why does my lawn mower leave a trail of grass?
If you see a trail of grass clippings on one side of your mower, it’s very likely that your mulch plug isn’t in correctly.
One of the most common reasons a lawn mower leaves clumps of grass is because the cutting blade is broken or not in the right place.
A lawn mower blade that turns but doesn’t cut is one of the most annoying things. I’ve done that before: pulled a lawnmower across a lawn while the engine screamed but didn’t cut any grass. You might be able to solve the problem by moving and changing a few things.
