I have a Toro Timecutter SW3200 ZT single blade mower I am trying to change for the first time. I am having trouble getting the bolt loose. I do not have an impact wrench. So, far I have just tried using a wrench and no luck. Before I go to more extremes I want to make sure I am pulling the right direction. Is lefty loosey counter clockwise the proper loosening direction? Years ago I fought with lug nuts on an old Chrysler until I noticed the "L" stamped on the stud. :ashamed: I don't want to snap off the bolt in the mower. I will spray it good with some lube and use the old block of wood.
