hello good people! So I have finally broken down and purchased my own impact wrench to make life easier. Today I used the method where you drive your front castors up on your trailer gate to get underneath to remove the blades. The only blade that I had enough clearance to remove was the center blade. The side ones were too close to the ground still. I tried several angles, etc. Any bright ideas would be great, besides buying one of those jacks. I am in search of a very cheap, temporary fix for now....if there is one. At least my middle blade is sharp! ha ha.
