That dosnt make sense. i would guess that the spark plug wire is shorting out to the metal in the handle but if that was true the machine should die as soon as you gave it gas
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 :
(1) The blades should always be turned on at full throttle if the mower has a electric P.T.O. switch.
The lawnmower requires a working throttle to start. If the throttle is stuck in one position, the engine might not receive the correct fuel mixture to start. Most throttle problems are solved with cleaning, lubrication and slight adjustments of the throttle cable, which leads from the throttle control to the engine.
Lawn equipment (including lawn mowers, lawn tractors, and even trimmers and blowers) is designed to run at full throttle to give the best performance. Your blade will turn faster at higher throttling, which is essential to proper cutting.
An improperly routed belt can cause the engine to die when the blades are engaged. To check belt routing, lower the deck to its lowest setting and remove the belt guard by the drive pulley. Next, lift the belt over the pulley and remove the pins that support the deck at the rear.
The best speed to engage the PTO clutch is always the lowest possible speed that provides a smooth engagement for the machine. There is some misinformation published by some manufacturers that the clutch should be engaged at the fastest possible speed.
The blade is designed to slip and shear the pins under these conditions, that`s why the correct torque is so important. Tightening the blade bolt dead tight using guesswork won`t allow the blade the critical amount of movement, and so instead your crankshaft bends – engine damaged beyond economic repair.
Blade bolts should always be torqued to the proper range. For the 7/16 GR 8 bolts (5/8″ wrench) used on some mowers, torque to 45-55 ft lbs. Please use the factory bolt because there must be a recessed area in the washer. For the 3/8 x 24 GR 8 bolts (9/16″ wrench) used on other tractors, torque to 30-40 ft lbs.

Replaceing mower deck belt on 20 hp 42 mower model no 917275660. Got the belt on. How do I get the cluch spring back on.
ANSWER : Are you refering to the spring attached to the end of the cable that runs up to the lever on the dash to engage the blades? All you needed to disconnect was that cable on top of the idler arm that’s held in place by a ‘hairpin’ and the left pulley cover to put the belt on.

The mower deck clutch cable broke so blades will not engage and lever is loose on my Sears Craftsman 42-inch lawn tractor (917-271-742). I fished out the top piece of the cable, about 12 inches down to a rusty point where it broke. If I get the clutch kit (175067), which includes the cable, spring, etc., can I replace it from the top, or do I need a lift to get to the mover deck from the bottom? I do not have a lift or ramp that would work. What would I need to remove to get to the location where the cable/spring assembly hooks up to engage the blades?
ANSWER : I just got the kit 175067. Have the old one off except for where it’s attached to the lever, schedule and weather has kept me from going further. Very simple to reconnect things at the pulley and above but not too sure how to connect the rest onto the lever and haven’t had a chance to get a good look at how the old one might be connected yet. Should be a simple fix.

I have a TORO XL380H Lawn Mower. When cutting long grass yesterday, the engine cuts out, as it often does when encountering grass that’s too long. I normall restart the engine, move teh mower to shorter grass, re-engage the baldes and off I go. This time, when I re-engaged the blades, it immediately cut out again. Assuming, there was probably long grass tangled in the blades, I restarted the mower, drove around a bit and then tried re-engaging the blades (by pulling out the PTO button). This time, they appeared to engage (the engine normally splutters slightly and the tractor jolts as they engage) but they almost immediately disengaged (you can tell by the engine noise). Also, when engaged, I am unable to get the ‘Keychoice’ function to work. This suggests to me the blades are not engaged. Help!

When I engage the clutch, the engine dies. The baldes turn freely, so it looks like and electrical problem. Is there a safety device that would kill the engine when the clutch is engaged?
ANSWER : All modern riding mowers now days have several safety switches and or relays/micro switches. Some are simple blade switches that make or break contact depending on the position of a lever. There is a contactor under the seat that will kill the engine if you fall off(you have to sit on it for it for the engine to keep running). There is one that kills the engine if you put the mower in reverse with the blades engaged. And there is a contactor that senses wether the mower blades are in fact engaged or not. It may be awkward but you can look at all the mechanisms and find where the different contactors are and move the levers back and forth to see if they aren’t dirty, bent, or a securement screw is loose or missing. It is also possible that one of the wires are broken or have come off of its connection point. Once you inspect them you should be able to determine the next course of action. These are not hard to fix although they can be difficult to get to. If it has a micro-switch at one of these locations you may need to test it with a continuity meter to determine if it is good or not.
