My wife and I had a chance to try out the Kubotas yesterday. (in OK, no NY trip here)
The difference in ergonomics is amazing. As expected, the standard 'L' was basic (but better than I thought it would be). The Grand was better - but not in the same league as the Yanmar. this is important to us b/c she will operate it even more than I will.
Mechanically, the Yanmar beats the economy 'bota in almost every respect. Not surprising, as the red one is a deluxe model. But they are priced the same. The Grand was significantly higher priced. And still no Yanmar for ergonomics.
The Kubota salesman suggested that they sell the economy rig about 20 to 1 for the the Grand. From the paint fading, I think he might have been understating the proportion. From my casual observations, most folks are buying the economy machines. My wife gasped when i showed her the difference in specs (dump, lift height, hydraulic flow, etc). I know that the limited number of folks that I have spoken with have ended up being frustrated with the economy tractors.
I think Yanmar could push out more tractors if they offered an economy one. But, I for one agree that their machines set a high bar for technical, mechanical, and ergonomic design.
I am interested in hearing what impressions others have.
