The last time I had to adjust the head on my "30" I realized how old & weak Im getting....almost powered me out to crank the damn thing so that wheel looks like just the ticket.
I started going thru my memory bank trying to remember who in the neighborhood would have an old Massey combine with the "header lift wheel" still on it...'but came up empty( memory is another "old man" affliction) so i came up with the idea that a trip to a local transport truck wrecker for an old steering wheel that might give me a big enough radius to ease the cranking effort.
