I was mowing lawn and the pto switch kicked off and the only way i can mow the lawn now is to hold the switch on
Your battery may be low. Check water level and charger often is power is low the electro magnet will let go. Holding switch could cause too much power and burn out coils on magnet.
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 :
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.
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.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
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.
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.
Adjust the pressure by turning the valve stem with allen wrench in the hole through the spool. Screw stem up into block for more pressure and thread it down or out of block for less pressure. Do not exceed 300 PSI or you`ll damage to clutch pack.
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.
An object or obstruction (such as an ant hill, clump of matted grass clippings or large tree branch) is jammed underneath the cutting deck or in the cutting deck drive system preventing the moving parts from engaging properly. Inspect for obstructions and carefully remove if necessary.
There are 4 safety interlock switches on our lawn and garden tractors. The locations vary slightly between Step-Thru® and box frame tractors. See Step Thru Riding Mower for help identifying a Step-Thru® frame tractor.
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.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
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.
Power take-offs (PTOs) are an attachment connected to large vehicles (such as trucks, harvesters and tractors) as a power source for a range of accessories including mowers, wood chippers, water pumps, compressors, and a range of farm equipment like balers. PTOs convert the rotating engine power into hydraulic power.
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.
On a Putzmeister MR 688 series the PTO Pump/Drive switch gets its power from a fuse located in the Mack fuse block.
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.
Stretched clutch cable/worn linkage. Air in the clutch hydraulic system/faulty seals. Adjustment not carried out correctly, or has come loose and backed off.
When the clutch is engaged, the disc is “squeezed” between the flywheel and pressure plate, and power from the engine is transmitted by the disc`s hub to the input shaft of the transmission. In layman`s terms, a pressure plate is a spring-loaded “clamp,” which is bolted to the flywheel.
If there is too much freeplay, the clutch may be dragging. Over time the clutch wears down and requires adjustments. The clutch freeplay must checked and adjusted at every 6,000 miles or as specified in the maker`s service schedule.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong. Don`t get left at the side of the road with a vehicle that won`t shift into gear.
The retainer nut on most of our riding mower blades are a 5/8″ thread diameter. This sized thread diameter nut normally requires a 15/16″ wrench or socket tool in order to remove/install.
There is a safety switch at the end of the cutter engage lever which has gone faulty and needs replacing, overiding the switch by keeping it pressed in will allow the mower to be operational till replacement switch is fitted.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
