Not often do I have to cut the bolts off. I have the blade carrier on the bench, place the bolt head on a socket so that it is held up inside the blade carrier and the rattle gun gets them off 99% of the time. You do realize that the 550 uses the big heavy blades that are used on the 24's and I think that you probably should have gone for a 24 as these are the real deal when tacking bigger areas, only downside is they are not self propelled but they really tackle kikuyu with ease.
Hi Norm,
I actually tried exactly this but had no luck at all - I also tried all manner of things pushing against the bolt head and none of them helped even going so far as to use an off centre g-clamp I had. The bolt would always spin as the diamond shape in the carrier disc had been damaged by the previous owner & also they were rusted, put on with no lube and also put on incredibly tight.
Alas 24's not being a SP really wouldn't help me that much - I will keep them in mind for the future BUT I really need a SP for the summer months and how thick and fast the grass grows on the slopes here. :-)
