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 :
Powershift PTO engagement problems could be from blocked hoses or fittings, bad connections or ground or the solenoid. Mechanical PTO engagement problems could originate from low air pressure, improper cable installation or back lash too tight.
Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try.
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.
Pump trouble is usually characterized by increased noise, increased heat, erratic operation of cylinders, difficulty or inability to develop full output, decreased speed of cylinders or hydraulic motors, or failure of the system to work at all.
For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. This locks the PTO output gear to the output shaft and allows work to be done. When the power shift PTO is disengaged, the solenoid de-energizes.
It may be a bad spindle bearing that is seizing up when you engage it which puts too much load on the engine and makes it die. You may hear some squealing sounds from the spindle and the belt may smoke. Most all these spindles can be taken apart and you can easily replace the bearings.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
When the Power Take Off (PTO) switch is turned ON, 12 volts is sent to the PTO solenoid to engage the PTO. This sends transmission pressure to the PTO to engage. When pressure is sensed, the PTO pressure switch sends a signal (usually ground signal), to the chassis controller indicating that the PTO is engaged.
PTO clutches generally overheat because of improper lubrication/greasing (both too much and too little can cause problems), excessive sideload, or a new installation. Operators are advised to reduce sideload and inspect grease levels first.
When air is present in a hydraulic system, the desired instant system reaction is slowed and results in a slower actuator response or a “spongy feel.” This is due to the compressible nature of the trapped air. The air contained in a system is alternately compressed and decompressed as the actuator is cycled.
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 power takeoff unit, more commonly known as a PTO, is a mechanical gearbox connected to the transmission that transfers power from the vehicle`s engine to an auxiliary component such as a hydraulic pump.

What is the Function of the pto control
It is to supply power the electric clutch that drives the mower deck.
If not functioning then the switch, PTO clutch, or wiring is not working properly. Note on some ZTRs when both handles are in reverse then electric clutch is disengage for safety.
My husqvarna zero turn mower has an auto safety shut off. I have isolated 3 (Brake, Left control level, and Right contol lever)trying to see which one was faulty, but I’m not sure where to go next. When I took the brake off, the mower stalled so I held the safety button down and when the brake was off the engine stayed running. But when I pulled the Left or Right Control level to move, it shut off, so I held those down to see if I could see which one was faulty. The engine stayed running, so I couldn’t figure out which one was bad. Every thing stayed running until I engaged the mower deck, and then it shut down again. I gave up at that point and figured I needed an experts help! Thanks, Jon Sable
There should be a switch under the seat. The system is designed to stop all functions if no one is setting in the seat. I believe the seat switch has failed.
Check it out and let me know.
I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.
Have a cub cadet GT 1554. When I engage the pto, it shuts the engine down. Could pto need replacing?
Probably spindles bad, or something wrapped around blades or belt
Lawn mower cranck but wont start…
Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.
Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
Husq 2348 riding mower blades engage, run for maybe 5 minutes, then disengage on their own
Sounds like your PTO switch or clutch has gone bad. Unfortunately, it is usually the clutch.
While cutting grass the pto clutch cuts off, i have to push switch in and back out to restart blades. I have replaced the switch and pto clutch
Pto kicks in and out while mowing was wondering if its electrical or something else i have a jd 420
Need the pto to work on a 6300 john deere tractor we have changed the fuses and changed the sencer on the back can you help
If you have tried a new sensor and a new switch the the next step is to replace the pto solenoid valve.If that proves fruitless then the b.c.u.needs to be replaced or bypassed.The solenoid valve will cure your problem 90% of the time.If that does not work,let me know,i can tell you how to by-pass the b.c.u..
