Possible explanation: RScotty once posted that after Yanmar closed its dealerships here mid-80's, there was a warehouse of unsold US-model tractors that sat for many years before the final one was sold.
I don't think anyone but individual owners renovates the US Yanmars. I bought several renovation parts for my YM240 from the local wholesaler of VN 'refurbs'. Their shop was always busy on warranty repairs and bodywork to repair shipping damage. I asked if they could renovate the appearance of my YM240. They wouldn't touch it - too rough,
more beat up appearance than what their VN factory buys for renovation, they said.
