You need to get deck about 6" off ground for working room. Have someone hold a
blade while you give wrench a good bump with block of wood or soft face hammer to break the nut loose. Use something to protect your hands-handling the blades. They can cut you, as I did. When reinstalling the blades, be sure bevel of blade is turned up, or they won't cut when running. Only hold the pulley in starting the nut back, until you
can hold the blade. Older mowers with friction type blade holding will be much harder
to tighten and may be a special tool for that. Use all safety procedures and check the
factory manual recommendations for doing this. You can do it, it worked for me!
Most lawn tractors don't have any fancy clutch system, but simply use the belt to engage and disengage the blades. When the blades are disengaged, the drive belt is slack and there isn't enough friction to the pullel to drive the blades. When engaged, the belt is taught and the belt drives the blades. Tension is controlled by a spring loaded pulley. When you pull the lever to disengage the blades, you pull this pulley away from the belt. When you engage the blade, the spring pushed the pulley into the belt, tensioning it.
If it is a push lawnmower, probably (Although I have seen one with an electric starter). If it is a riding mower, probably not. On a push mower, the hub where the blade is bolted onto is attached to the engine driveshaft via a keyway and a fastener (nut). Therefore, the blade is not driven by a pulley. On the contrary, on a riding mower, the blades are usually driven by a belt that transfers motion from the engine shaft pulley to another pulley that spins the blade(s).
probably a loose or streched drive belt. also the drive pulley could be loose. the main thing wrong is that it is a craftsman. my experience with craftsman products has been very unhappy, they are starting to make junk. try a John Deere product the next time you will be glad you did.
If the engine is running properly and the blades are not working there are a couple things that could be causing it. 1) The cable or linkage that operates the pulley to engage the blades is broken or bent. 2) One of the pulleys are bad. 3) The belt is broken. #3 would be the most common problem.
On a 2007 MTD Yardman riding mower, the pulley tension spring is typically attached to the deck engagement lever and the idler pulley. The spring helps maintain tension on the idler pulley to ensure proper belt engagement for the mower blades. To install it, locate the spring attachment points on the lever and idler pulley, ensuring it's securely connected for optimal performance. Always refer to the mower's manual for specific diagrams and instructions.
The electric PTO Clutch is Electromagnetic. There is a stator which creates a magnetic field when voltage is applied and this causes the free spun pulley to lock into place with the crankshaft of the engine. When voltage is release, spring pressure forces the pulley away from the stator. This is over simplified but that is about it.
"Craftsman" is an entire range of tools and equipment and YOU haven't even said what the tool is !How do you expect a reply giving you a proper answer.
The part of a pulley where the rope lies is called the groove or the sheave. This is the part of the pulley that provides the surface for the rope to run along while the pulley rotates.
The antonym of pulley is likely "fixed point" or "immobile point". A pulley is a mechanism that rotates around an axis, while a fixed point does not move or rotate.
Use a puller so you do not bend the pulley.
To replace a Craftsman starter pulley, first, disconnect the spark plug to ensure safety. Remove the starter assembly by unscrewing it from the engine. Take off the old pulley by detaching any retaining clips or screws, then install the new pulley by reversing the process, ensuring it is securely in place. Finally, reassemble the starter assembly and reconnect the spark plug before testing the starter.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
