The manufacturers instructions should include the blade size for your weed eater lawn mower.
15/16''
Mow-Aerator Riding Lawn Mower is the one you want to get.
A push lawn mower is easier to store if space is an issue. They are ideal for smaller yards and come in many varieties. A riding lawnmower would be ideal if you have a large yard and space to store the mower isn't an issue.
Remove the bolt holding the blade to the left
Use a 9/16" Socket on a ratchet. There is one bolt in the center of the blade. Brace the blade with a block of wood to prevent movement. Loosen the bolt, remove the bolt and washers. Blade should come off easily now. Place your new blade in the spindle cradle and transfer the bolt and washers to it. Tighten with socket/wratchet. It's that easy! Unless, the bolt is stripped, in which case the mower deck will need to go to a machine shop to get the bolt out.
It will depend on what kind of mtd mower you got but generally there is a bolt in the center of the blade that you take off and the blade will come right off. It is alot easier to take it off with an impact but if you dont have and impact you will have to put something to hold the blade and break lose that bolt and make sure when you put it together the blades go back on the same way and if the blades have any kind of bracket on it you put those back on the same way as well.
Sometimes Evelyn's lawn mower does this too. I take a sledgehammer and break it.
You can remove a rear wheel from your Husqvarna riding lawnmower by loosening and removing the lug nuts. The wheel should come off.
That's not much info to work with. But, assuming that you are talking about a riding mower which quits when you engage the blades, I would tell you to check out the seat safety switch. For some readon the mower doesn't think there is anyone on the seat. It will not run with the blades engaged with no one on the seat. Somewhere attached to the seat you will find a small switch with two wires going to it. It may have come unplugged or it could just be a bad switch.
Commonly counterclockwise. Most left-handed threaded fasteners will have some marking.
Try going to www.managemyhome.com and entering your model number there. That is the best place I have come accross for manuals.
In order to learn how to remove the real wheel on a Cub Cadet riding mower one may want to look on the Cub Cadet forums for advice. For a more efficient fix, though it will cost more, taking it to a lawn mower repair shop might be best.
