Aelf, Good to have you with us at LMF...
Blocks ramps lifts or hoists, there have been lots of lift methods gone over... what ever method you use it is not going to be perfect, but fortunately you do not have to get under it often. U use my big tractor and pallet forks to lift things up to the point I can see what is going on under them without having to lay on the ground...
I'm old enough that once I lay down .. the first thing that comes to mind is a nap... especially if the warm sun is shining...
Good luck with your Murray, AND you will be very satisfied with the work done on it, if it's done by YOU.
There is not much more rewarding than doing any job yourself... :smile:KennyV
