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 your tractor cranks, but won`t start, you`ll want to look at a few different engine components. Is the fuel making it to the cylinder? Check the fuel level, the shutoff valve, and the fuel filter. If those components look ok, air might not be making it to the cylinder.
According to Raby, the primary reason a diesel tractor turns over but won`t start is because air is present somewhere in the fuel system. Running a tractor till it`s low or out of fuel and a clogged fuel filter are two of the more common ways air gets into the system.
Reasons A Diesel Engine Won`t Start After It`s Been Sitting
The most common are interrupted fuel delivery, problems with injectors, or a contaminated fuel line.
A spark plug is the most likely cause of a hot starting problem and is the easiest problem to solve. A new spark plug should be fitted at the start of every season.
If your battery doesn`t have enough power, it can keep your tractor from starting. Check if it needs to be recharged or replaced. You can tell if the battery needs to be recharged below 12.6 volts. If it`s above 12.6 volts, but the tractor still won`t start, it might be time for a new battery.
Fuel injection pressure
If your diesel engine won`t start, the problem could be the amount of pressure in the fuel system. The engine may not start if the fuel pressure is too low. Fuel pressure that is too high can cause damage to the exhaust system while also increasing soot pollution in the exhaust.
Glow Plugs and Block Heaters: The use of glow plugs or block heaters will start the vast majority of diesel engines on a cold day. Glow plugs work by heating the internal combustion chamber so that conditions are suitable for compression and ultimately ignition.
When you run low on diesel, your fuel pump might send air through your fuel system instead of gas. If that happens, your vehicle will shut down and not restart until the air is removed. This is called “bleeding” the fuel system, and depending on your machine, it can take several hours to complete.
Also the most common reason of the difficult diesel engine warm start – wear-out of the plunger and barrel of the fuel pump. If plunger and barrel are worn out – cold fuel can be transported; however, as soon as the fuel warms up – it becomes more watery and cannot be transported by plunger and barrel easily.
“Hot-starting” refers to the ability of an engine to fire up and start whilst still at operating temperature (after a breif period of being off).
Broken or Damaged Ignition
If your headlights can turn on, but your car won`t crank, that means that your battery is charged, but either the starter or ignition is the problem. If the starter or ignition is the problem, a starter engine can be jumped by using a charged battery.
In bypass starting, you touch a wrench or a screwdriver to the terminals of the starter motor, to the solenoid of a tractor, or to other equipment. This bypasses all tractor-neutral starting switches. Sparks fly and electricity snaps as the circuit is completed, the starter engages and the engine starts.
Why does the tractor make a clicking sound and not start? If the riding mower makes a heavy clicking or a rapid clattering sound when the key is turned to the start position, there is a problem with the battery or a part of the starting circuit. The clicking noise comes from a part called the starter solenoid.

If your tractor is making a clicking sound when you turn the ignition, this may be a sign that there is an issue with your tractor starter motor. If you hear a whirring sound it may be due to the pinion gear not engaging with the flywheel.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.

1 Start motor engages but the engine doesn`t turn
The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.

I have John Deere GX345. It does not start consistently. When it doesn’t start the plugs have no spark. The problem is intermittent.All electrical connections look clean and no corrosion. Re- seated all connections. Fuel flow is good because I can smell raw fuel while cranking the motor. I replaced the fuel lines last year. Thank you for your help. Daryl Witowski
ANSWER : Look for a small silver box with 1 wire on it mounted to the motor. It is a temp sensor and will keep it from firing…Just had to replace mine…

My Tractor (425) won't start – John Deere 420,1020,2010,2020,2510,2520 Tractor Float
ANSWER : If you have no spark the first thing to replace the time delay module on the left rear side of engine. Its black and about 2 inches by 1 inch with yellow,red,orange and black wires going to it. Replacement is round shaped with same amount of wires.If no fuel to carb check for flow at filter, if theres flow but no pressure look for a split fuel line in tank between pump and sender.

How can I restart my 4020 diesel after it ran out of diesel?
ANSWER : Crack open the line coming into the injection pump from the fuel pump (near the top of inj. pump, towards firewall). Pump the lever on fuel pump until fuel comes out of loosened line. Tighten line. Loosen at least two injector lines at injection pump head. Crank engine with starter until fuel pulses from loosened lines. Tighten lines. Crank engine again. Engine should begin firing on these cylinders first, followed by the remaining cylinders.
