Georg,
I too, was inculcated in the ways of Gravely from an early age... from about 5 years on, I mowed about 3 acres with Dad's walk-behind, riding the tag-along sulky. The most important thing ( aside from not getting killed ) was no to stall the engine in heavy grass, because then I'd have to walk back and find Dad to start it again... strap starter, and I didn't have enough weight / strength to pull that beast over.
I grew to love them, and in HS had a small lawn-mowing business, using a couple of 1940's Gravely's that an uncle had given me, lugging them around in my Grandad's 1954 Chevy ¾ ton pick-up. (This was circa 1984)
There doesn't seem to be any middle ground with Gravely - folks either LOVE them, or HATE them, either way with a passion.
Eventually, I found a "Custom Convertible" from 1964, with the "Swiftmatic" two-speed axle, and an electric starter

... and many of the accessory toys...
I live in a city residential street, and an 18" Lawn-Boy is more than enough to take care of my little patch of grass, but I still love my Gravelys, and will probably hang onto them until I croak.
With all the myriad attachments made & sold for the Gravely tractor, I'm surprised a phonograph powered from the power-takeoff wasn't among them...
