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 :

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.
Blade(s) will not engage

If belt is too loose, make belt adjustment. Check engagement spring on deck engagement idler. If broken or damaged, replace. Check for and remove all foreign objects interfering with engagement idler travel.

Check your grass bag isn`t clogged

This is one of the most common causes of poor grass collection. If the lining of your grass bag is clogged with old grass you should clean it using a jet wash, air line or simply a brush and water.

Wet grass and debris clog the mower`s deck over time, eventually preventing the spinning blade from cutting more grass. Some solutions you can try when faced with this problem include replacing the blade, fixing the tire pressure of the mower, tightening the mower belt, or sharpening the blade.
The edge is sharp enough to roughly last for 25 hours of mowing and is dull enough so that the blade won`t get easily damaged by roots and rocks. If a mower blade has a super sharp edge, it would bend over in the first 5 minutes of mowing!
It could be your bearings and your spindle pockets, or spindles, have seized up,” says Oshel. If the blades are stuck, pump some grease into the fitting and carefully work the blades back and forth by hand until they move freely.
If the engine starts, but does not run smoothly, it means that the spark plug and ignition system are in order and you need to look elsewhere for the source of the problem. The usual culprit is air intake or fuel system related.
Why is my mower leaving a trail of grass on the right hand side? The issue is probably the amount of material that is being cut. The blades turn counter clockwise, so if you try to cut more material than the unit can handle, you will have a windrow of material build up on the right hand side.
The engine powers both the wheels and the blade, just like a walk-behind self-propelled mower. But instead of being directly connected to it by an axle, the blade on most riding mowers is powered by a belt connected to the engine.
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.
Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side. If you are unsure of how your mower rotates, check the position of the discharge chute; if it is on the right side angled back, the blade turns clockwise.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!
