Interesting tractor... Sanyo was a Chinese company before Panasonic bought them out.
The engine is likely one of the usual Mitsubishi industrial that is/are/were used worldwide, what does the block plate say the model is on it? That will go a long way to identify what it crosses over with.
Load Master was/is a made in America brand but the logo seems off and is reminiscent of the 60/70's style, for something built in the 1980s.
If someone can confirm the language on the decals, you would get more information about where it was possibly built.
I suppose it is possible that it is a hybrid MT280 grey which would have it at 28hp?
Half expect it is likely a rebrand Iseki version, post coldwar sentiments and all that.
Edit: maybe it is simpler and the dealer had a falling out with their supplier/distributor and was barred from selling the brand so they slapped a new sticker on the inventory to clear it out.
