If you name her "Snow Queen" you may feel awkward during the summer. Perhaps a little research on ancient Greco Roman goddesses that were associated with the outdoors?
You have a point there. ;-)
Of course, in July and August, the name could be laced with irony. ;-)
In Roman mythology, Diana the Huntress was certainly an outdoorswoman. But Angerona 's festival was celebrated on the 21st of December, associating her with the Winter Solstice.
The Norse analog to Diana was Skadi or Skathi. She was associated with bow-hunting, skiing, Winter, and mountains. She was also the goddess of justice, vengeance, and righteous anger.
In this circumstance, Skadi/Skathi may fit well, as I am a lawyer by profession. (I am also an Electrical Engineer, so please cut me some slack if you have an aversion to lawyers.)
There are a lot of bow hunters around here.
In Greek Mythology, Khione is the nymph of snow. She is the daughter of Boreas (the North Wind), and Oreithyia, a mountain Nymph . Boreas and Oreithyia lived in a cave on Mount Haimos (Mount Haemus) in Thrake (Thrace).
The Norse god Ullr was often depicted wearing skates or skis. Many skiers pay homage to Ullr, at least metaphorically.
Maybe I should call the tractor Jack (short for Jack Frost), or in homage to one of my favorite bands, Spirit, Uncle Jack.
(I did have an Uncle Jack. Unfortunately, I never met him. He was a navigator on a B25, shot down in Burma during World Wr II after he had flown his 25 missions. On that fateful day, he filled in for someone else who could not fly. He was the Officer of the Day., so he filled the void. He never came back. I was recently contacted by the Army and asked to submit a DNA sample, as it appears that remains may have finally been found.)
Other possibilities...
Cailleach Bheur: the Celtic goddess of Winter. As you can probably guess from my surname, my forebears were Celts. As the saying goes, I am as Irish as Paddy's Pig, on both sides, as far back as is traceable.
To anglicize, it, Kayleigh. I like the ring of that. My best friend from college not all that long ago sent me some music recorded by a band called Marillon. One of the tunes was called
Kayleigh.
Yuki-onna.. the Japanese Snow Woman. A woman dressed in white, who appears on snowy nights. Now, if she were wearing greige and red, that would be perfect. Still, I love Japanese food, architecture, and art. And the Japanese make some very good tractors, as well as very good internal-combustion engines. The 4500Y, as you know, has a Kubota engine.
