I was backing up and the left rear tire got caught on the fencepipe. Now the mower blades seem to be turning at twice the normal speed and will not fully disengage.
What might have happened?
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
The possible causes of a lawn mower blade spinning but not cutting grass include a damaged or wrongly installed blade, a dull blade, or damaged lawnmower tires. Other possible reasons can be improper tire pressure, a clogged deck, or a broken mower belt.
Worn or broken blade drive belt – If the riding mower blades are not spinning, the blade drive belt may be worn or broken and unable to engage the blades. If the belt is intact, inspect it to see if it`s loose or slipping on the pulleys then replace it with a new one if necessary.
Power take-off (PTO) clutches provide a mechanical disconnect between the power created by gas and diesel engines or electric motors to another piece of equipment. The PTO clutches enable the transmission of that energy to auxiliary equipment that does not generate its own power.
Mower blades are spinning 4000 RPMs. An unbalanced blade spinning that fast will cause a significant amount of vibration, which will put stress on yout blade shaft, spindle, and even the engine.
Identify if Your Lawn Mower Blades Need To Be Balanced
So to ensure that your lawn mower blades need balancing, look for unbalanced lawn mower blade symptoms like your lawn mower is not giving your grass a quality and even cut, as well as vibrating and making odd noises while running.
The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.
Unfortunately, you can overtighten your mower`s blade if you aren`t careful. This can damage the blade itself in some cases – the blade can even break after hitting a hard object if it`s overly tight. Apart from that, the bolt that`s holding the blade in place can also get damaged (this is often the case).
The Blade Lock is a revolutionary safety device that holds a standard single edge razor blade on your clothing, tool poach, work space or anywhere a razor blade is needed. The razor blade can be accessed instantly and safely without the need for caps, retractors or holsters.
Place the blade bolt into the centre hole and then tighten it to a torque of 30-35Ft/Lb or 45–55Ft/Lb, depending on your mower type. It is important to check bolt specifications for your individual mower`s torque settings to ensure it is not over or under torqued.
If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.
Deformed Blade
In some cases, the unnatural shape of the blade can be enough to prevent you from tightening it properly. A bent shape can also mess with the blade`s overall balance. An unbalanced mower blade can produce vibrations that will loosen the bolt over time.

This operation is crucial to the overall functioning of riding mowers, and thus PTO clutch repair may need to be immediately performed on riding mower models that have a failed clutch. Fortunately, you can fix your clutch irrespective of your experience with PTO clutch installation.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

Power to turn the blades is intermitent. What should I look for?
ANSWER : Loose connection, corrosion on connections. If this machine is new to you, do you have to have the brake or clutch on to activate the blades? I would lean towards wires/connections as the cause of your intermittent problem.

Serviced my riding lawnmower runs great. but when I put in drive it dies out. Also when I engage blades it dies out. No problems last summer. It won,t stay running when I do these two steps
ANSWER : Probably the seat safety switch. If it’s not activated (from your weight on the seat) the engine is killed when you put it in gear, or engage the blades. Lift up the seat and check the switch – wires on tight? switch tightly mounted? You can take the switch out and tape it in the pushed-in position to test things. If that doesn’t let the mower run, the switch itself is probably bad, but it could also be a connector that knocked loose when you serviced the mower. Check wires and connectors. Good luck!
