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 :
The pulleys in your lawn tractor are driven by the drive belt, and turn the spindles. If a pulley doesn`t spin freely, it can cause the engine to die when the blades are engaged. To check the pulleys for sticking and damage, first remove the drive belt from the engine pulley and lift the lever to engage the blades.
The tractor`s stub shaft, often called the PTO, transfers power from the tractor to the PTO-driven machine or implement. Power transfer is accomplished by connecting a drive shaft from the machinery to the tractor`s PTO stub shaft.
This is most likely a safety switch issue. Usually the seat safety switch will cause this problem. The mower dies because it thinks nobody is sitting in the seat, and shuts off for safety reasons.
Clogged or Dirty Air Filters
It is one of the most common problems that cause lawnmowers to sputter. The mowers take the air from the surrounding through air filters and mix it with fuel inside the engine. So, if the air filter is clogged or dirty, it will affect the flow of air into the carburetor.
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.
The design of the PTO itself is a two gear mechanically shifted Rear Mount PTO that is attached to rear mount apertures of a transmission.
The 540- and 1000-rpm speeds allow for standard PTO operations for higher power requirements within the constant power range.
The PTO (or power take-off) belt is part of a pulley system that operates the blades on your riding lawn mower. It runs off the electric clutch system in your engine. If you hear squealing during operation or see dry rot on your PTO belt, you may need to replace it.
Sounds like your mower can`t produce enough power to cut the grass, although it does produce enough to run. This could be caused by not enough air getting into the system, not enough fuel getting into the system, or the fuel/air mix not burning well enough once it gets into the cylinder.
Most problems that will cause a John Deere lawn mower to stall after 20 minutes occur due to the distribution and rate of flow in the fuel and air systems. If these systems are dirty or restricted, the mower will stall out and be difficult to restart.
(1) The blades should always be turned on at full throttle if the mower has a electric P.T.O. switch.
Clogged or Dirty Air Filters
Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.
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.
Broken, damaged or badly fitting PTO guards are as dangerous as an unguarded PTO shaft and can easily give a false sense of security and so increase the danger. Remember, never wear loose clothes when operating machines powered by PTOs.

The most common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.

Mowerdeck will not engage… – John Deere 195HP Hydrostatic 42" Cut Riding Mower
ANSWER : I own a similiar John Deere model (L130, 23HP with a 48″ deck). I would check the electric clutch (called a PTO). To do this check the wires to this clutch and look for something disconnected. These wires (to this PTO clutch) should have twelve volts with the key on and the blades engaged.
