SOURCE: replace blades on a john deere L120 mower deck

First make sure you have the tools, metric that is. The deck must be removed and turned over. To do this you must put the deck in the lowest position. Using a 15mm socket pull the belt tension spring pulley forward to detach from clutch. Next remove retaining pins located at the five deck brackets. This will allow the arms to slide off and the deck can be dragged out from under the mower. Turn deck over. Use a 18 inch 2x4 to block blades while removing the two 15mm bolts. The bolt heads will need to be cleaned so the socket can seat on bolt head. I use my torque wrench to get more leverage and i can use it to reset blade bolts to 64 ft lbs. While blades are of it is a god time to thoroughly clean underside of deck.

SOURCE: My John Deer L120 riding mower is shutting down

Two things to and fuel. Lets start with the simplest....check and replace the fuel filter, drop bowl off the bottom of carb to make sure float is working properly. If this dosen't work...your looking at a new coil. Some coils will go quickly where others are gradual. As they heat up...they will stop working until allowed to cool down again.

SOURCE: Electric Clutch want engage the mower deck on my l120 john deere

They wear out. How old is the mower? Mine just gave out this week in the peak of hay season. (my grass) The wire can be unhooked from the PTO clutch and a 12 volt jumper can test it, if it jumps, it is good, if not, it is shorted out, they are expensive, I found 3 of them all the wrong size for mine. Try to find the same one. Ebay has a couple on there right now. Check it out.

I have a probably 20 year old John Deere 130 lawn mower the mow deck is stuck in the highest setting and will not lower, how do lower it, Thanks

a 130 that's 20 years old , does this one have a black deck or a yellow deck , the black deck ones used a hydraulic cylinder (commercial model) and the yellow deck models used a grab bar just infront of the seat , you need to squeeze the handles together to get catch to release , then it should just fall down to it's lowest setting , that is if it's not rusted in place , a few squirts of soaking oil will do wonders on this

The blades only turn when the electric clutch is engaged. Sounds like you may have a short in the wiring possibly at a terminal that is shutting down the clutch. Or it might be in the "reverse button" you have to push to keep the blades turning when you back up. Try holding in on the button when it stops and see if they start back up. I think it's definitely in the wiring somewhere.

The left blade on my John Deere LT155 stopped working

Besides the drive belt, there is a timing belt inside the mowing deck. The left blade is run by the timing belt. I imagine the timing belt is broken.
