Cannot remove mower blade pulley nut - John Deere 22HP VTwin 48" Riding Mower

Pully shaft runs through deck to blade spindles. Wear floves amd wrap heavy rag around blade and hold tight whist undoing pulley nuts. Another option is to place a oil filter strap wrench around pulley grooves and tighyen to achieve leverage. Happy fixing.

OK I HOPE THIS WORKS I HAVE A T-13560 GUESSING THEY'RE CLOSE, I HAD TO PULL OFF THE TOP COVERS SHAPED LIKE A "V" WITH ONE NUT HOLDING IT ON ,FIRST REMOVE THE CENTER BLADE BOLT UNDERNEATH ...THEN YOU'LL SEE THEIRS 4 1/4-20 HOLDING THE BLADE DRIVE ON BUT FOR ME I ACTUALLY TOOK THE FOUR BOLTS OUT HOLDING THE ENGINE MOUNT OUT IE. THE CENTER OF THE DECK TO EXPOSE THE TOP OF THE CENTER PULLEY (MY BAD ONE) AT WHICH POINT I COULD TAKE AN IMPACT WRENCH TO REMOVE THE PULLEY NUT ...THEN UNDERNEATH REMOVE THE BLADE MOUNT ....MY BOTTOM BEARING FELL APART SO I COULD PUT THE SHAFT IN A VISE , HEAT IT UP AND TURN IT COUNTER CLOCKWISE ...THEN REASSEMBLE GOOD LUCK

Changing the Blade Drive Belts:
a.Set the parking brake. Remove ignition key and both spark plug caps.
b.Unscrew the wing nuts from the deck covers and remove both covers.
c.Using a 3/8" socket breaker bar or socket ratchet insert the drive end into the 3/8" square opening in the lower idler arm assembly and push the idler arm counterclockwise. While holding the idler arm back, loosen the blade drive belt from the pulley and slide the belt away from the pulley.
d.Remove tension of the PTO belt by moving the belt tensioning rod. Loosen the belt retaining bolt.
e.Pull the tensioner pulley away from the belt and remove the PTO belt then remove the blade drive belt.
f.Reverse the process to install the belt.

Sounds like the large nut on top of the spindle may have loosened up or the splines on the pulley are chewed up. Turn the blade and try to hold the pulley on top. If the blade turns and the pulley doesnt, its one of the two things I just described.

With most small lawn tractors I've dealt with, you want to unhook the deck-blade drive belt, some have one large belt that turns the blades as well as the rear wheels, others have more than one belt.. usually you will find four brackets that suspend the entire mower deck below the lawn tractor. To locate these brackets raise the mower deck so that its not resting on the ground, then push the mower deck side to side and notice where the attaching arms are moving under mower but above the deck, once you find the four brackets, lower the deck 2 its lowest point. remove the connecting pins noting the exact hole each pin came out of, if you have not removed the belt bye now do so at this time. you may find a stubborn piece of metal preventing the belt from coming off near the larger pulley Don't bend it out of the way just remove or loosen its nut,its there 4 a reason. so now, 1 the belts off the pulley. 2. the pins or bolts have been removed from the suspending arms and the hole positions have been noted. remove any other actuating rods or levers remaining so that the mower deck can slide out from under the mower. you may have to put the front wheels on a 4x4 blocks or similar to accomplish this. once you've got the deck out carefully turn it upside down, use blocks to keep from mashing pulleys, etc. you will probably see two or three blades, remove hex head bolt w/ washer holding blade to spindle, be sure to note cutting side of blade and direction of travel. If you don't see bolts in the center of blade look for my other solution for changing blades and blade bearings.

With the blade on and tight, block the blade with a piece of wood or someother means of securing it so it will not turn when you try to remove the nut. I then use a fifteen inch breaker bar and "massage" the bar with a four pound sledge hammer. A few moderate taps and it starts to loosen.

I hope this helps you get it off.

Before you put the socket on the nut on top of the pulley, you need to take a piece of wood and place under the deck in such a manner as to stop the of the blade when you turn the nut. You can also use a set of vice grip locking pliers or a large c-clamp to stop blade rotation also by clamping to side of deck. Then you should have no difficulty removing the nut from the spindle releasing the pulley.

If really helpful, please rate.

Hello. REmove the deck from your mower so you can easily get at the belt and the blade. Make a drawing of how the belt is installed so you can install the new one the same way, loosen the idler pulley and remove the belt. Generally you have to remove a couple of parts to get the old belt off in one piece and get the new one on. You will need a set of socket wrences. To replace the blade use a block of wood to hold the old blade stationary and a large socket wrench to loosen the nut holding the blade in place.

Hello jejodaro:

>>You have to Hold the Shaft on the Blade Side with a Pipe or Strap Wrench or Depending on the Model, you can Block the Blade an Hold the Shaft so the Pulley Nut can be Loosened/Removed.
>>If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
