Hello,
I'm trying to service my Hayter self-propelled mower. I want to be
able
to get the blade off by unscrewing the nut underneath.
unfortunately it
has been put on too tight by one of those machines they use. I've
trawled the DIY shops, but have been unable to get anything that
will do
the job. A simple sprocket set just isn't strong enough- I need a
machine!
They must be available somewhere, but I need to know what they are
called and where I can get one.
Thanks.

How about a Socket Wrench Breaker
bar?http://lmgtfy.com/?q=socket+wrench+breaker+bar

Absolutely. And if that doesn't do it slip a 3' piece of pipe over
the breaker bar handle.

Don't know the name of it and it's out in the workshop under tons of
other stuff, but there is a spray can of something, it foams when
applied, and you soak the culprit overnight. The next morning you can
almost loosen the thing with your fingers. If you want I'll try to
find my can and give you the name.
