    Question New 155 and can't get bolts off to change blades

    I bought a new 155 lawn tractor last fall. I bought some mulching blades to put on it this spring. I removed the deck and when I try to take the blades off they do not move. I've even tried with my drill and a socket adapter. I'm at a loss and will have to take it to a shop unless anyone here has a good idea for me. Any recommendations?

    Thanks

    A 155? What exact model do you have? The bolts can be very tight initially. Are you blocking the blades with a piece of wood so they cannot turn? It sometimes requires a breaker bar or an impact gun. I doubt just using a drill/socket will bust them loose.

    Block the blade from turing with a piece of wood. 1/2” breaker bar should take them right off.

    A drill will never have enough power to do it.

    Head to harbor freight and get their 2', 1/2"drive breaker bar! If that does not work, get a 1/2" drive impact.

    Hello from a fellow Georgian. I would invest in a impact gun, either air or electric depending on if you have a compressor handy. Beats grunting any day of the week. Also, use an impact socket with it.

    My snap on impact sometimes won't break them loose. I use a 4x4 block, a 1/2 good breaker bar and a 1 inch x 2 foot pipe added to the end. Make sure you position the block so it doesn't slip out and isn't going to bend something important. It works every time but can be a little dangerous especially if the blades are sharp. Don't ask me how I know.

    How much are you torquing the bolts?

    For the OP’s deck it calls for 42 ft lbs.

    Even for my 62D deck it calls for only 90 ft lbs - easy enough with an 18” breaker bar.

    I see in your signature you have a 54D deck - that calls for 50 ft lbs. You shouldn’t need a 2’ cheater pipe for that.

    And yes - I realize the blades can tighten a little on their own but I have never needed more than an 18” breaker bar - and I’m weak!

    It sounds like you could benefit from a little dab of anti-seize on those bolts. My blade bolts get torqued to 50 ft-lbs and my Milwaukee cordless impact loosens the bolt in about 1-sec.

    I'm talking about buying something that some ape has manhandled completely past the torque specs and I've even had issues on factory bolts also. I think the factory uses some type of thread locker or has on some. I've had to use my gorilla tactics on brand new tractors too. After I've put them back I've had no issues.

    I can see that happening. While not on my tractor I have been subject to one of those manhandling apes with my truck......
