Yep this mower is a HONDA Model: UM-T12 imported from Japan (new price, Japan 123,000 Yen.) Mini Mower
2-stroke gasoline engine, code GTV60, mix ratio 50:1, size 2.4 PS (PS = about 0.9863 of one horsepower) driven by 1 forward gear, 1 reverse gear. Cutting circle size, blade width about 30 cm., 1 cutting blade ,about a 12 inch cut.
Also have seen a few 2 stroke Honda line trimmers UMT28 .
The 123,000 Yen new, was a price I saw a seller in Japan saying that's what the new price was but I can't confirm it's right as that is $1,528. Australian dollars, looks like an over inflated price to me ,I've seen the UM-T12 listed second hand it Japan for a little over $500 Australian dollars but also seen them listed in Japan for a $100 Australian dollars.
