I'm assuming you take that red cover off the top then, with the front end of the mower held up with a 4x4, you put one wrench on the bolt near the blade and another wrench on the bolt in the middle of the pulley. IS that right? First I read the manual... not the best manual. It doesn't seem right to me, I'm thinking a whole lot of parts are going to come tumbling down. And none of my wrenches fit, it must be at least 1 inch these bolts and nuts. I tried it with two smallish cresent wrenches but I didn't have the strength to budge it one bit. I even had my guy holding the bottom bolt while I tried twisting teh top but it just spun out of his hand. It's brand new and I've never had a large wb before. I guess I'm asking do I need to go and buy extra large and extra long wrenches? I'm waiting for a certain cordless Impact wrench to go on sale.. every few weeks it goes down to half price. I could sure use it now though.
