John deere 325 garden tractor. bought it used, can't get blade bolts loose to replace blades. is there a trick?

It is self centering. The "Plastic" fan should have 2 nubs that align into slots/holes on flywheel. The fan must be rotated so that it seats in the flywheel indentations. Then the flywheel bolt and washer anchor the fan in the position required as to not damage fan,

Need slap out cable. On side of deck loose bolts

Most have a bolt. Hope bolt doesn't get loose. Retight the bolt good. Most blades have a certain place the blade seted.

check the wires just as they go into the clutch i have had them break there and have been able to repair the wire

Hi, warm the nuts up with a heat gun or oxy torch then try the impact gun while they are hot, regards Phil.

the drive and the mower deck use different belts

Of course with everything off, reach under the deck and turn the center blade by hand. If:
1. the blade turns by itself and nothing else moves, you need to tighten the retaining bolt more.
2. the blade, retaining bolt and drive shaft turn, check to see if the pulley above it is turning.
a. If the pulley turns freely check that the drive belt is going around it to power the blade.
b. If the blade turns with the drive shaft and the pulley doesn't, check that the pulley is still properly connected to the blade shaft. Some have a key in them that can split, others just have a bolt on top holding them tightly on the shaft.

As you are looking at the blade and bolt from under the mower, if the blade is rotating counterclockwise, then the blade bolt is standard threaded and will turn counterclockwise to loosen. If the blade is turning clockwise, then the bolt is left hand threaded and will turn clockwise to loosen. John Deere produces mower decks with both setups.
Good luck!

Always unscrew the bolt in the same direction of blade travel.If the blade travels clockwise,loosen bolt by going clockwise.

I have a John Deere lawntractor, 105. Won't start. Gas getting to the carb, but not getting into carb. Is this a common problem. Has been setting for a year. Any suggestions on problem
