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 :
You might have contaminated gas in the mower. Drain out the old gas. Change the fuel filter. Get new gas, non-ethanol if possible.
What are the Causes for Mower Blades that Won`t Disengage? The causes for mower blade disengagement are the loose engagement lever and the worn-out idler rod and cable. Other causes that can cause these bade problems are missing springs, defective idler arms, and mounting defects.
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.
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.
For riding mowers using a manual clutch, the mower blades are engaged by manually shifting a lever that moves a pulley assembly to tighten the blade drive belt. The rotating engine shaft will then drive the belt, which in turn, rotates the pulleys to spin one or more cutting blades.
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.
The most common reason a mower chute clogs are because the grass is too heavy, but there are lots of other reasons: Poor Cutting Conditions. Deck Too Low. Dull/Damaged Blade.
If the starter motor spins but does not crank the engine, you likely have a problem with… Faulty or damaged battery. To address this issues, check the battery and charging system for problems.
Typically, when the mower is cutting grass, the RPM of the majority of mowers drops to approximately 3000 RPM. Some even operate at speeds below 2,500 RPM but can still produce good cuts. When the blades are not cutting the grass, the majority of walk-behind and ride-on mowers operate at 3200 RPM to 3600 RPM.
Why would the cutting belt chirp or squeak when the cutting deck is first engaged? These belts are designed to suddenly grasp several pulleys and quickly get them up to a high RPM quickly. A short chirp or squeak is normal, especially when related components are new.
A perfectly tight mower belt can rotate without slipping off but not cause the engine to over-exert and overheat. If the belt does not slip off while working and is not producing unfavorable sounds that indicate wearing off of the belt, then that is the perfect tightness for it.
On average, a mower blade should be sharpened after every 20 to 25 hours of use time.
(1) The blades should always be turned on at full throttle if the mower has a electric P.T.O. switch.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
