check out this YouTube Exmark vantage Maintenance clip
It states that the spindles are greaseless. This makes me wonder if the possible typo (see above post) regarding the listing of greasless for the compact models is maybe an error in that the full size frame models left off the word greaseless. I look forward to Toro's reply to my questions above.
Also, unrelated, has anybody noticed the ground speed control of the Exmark Vantage compared to that of the Toro GrandStand? The Toro uses a dash-mounted lever while the reference bar of the Exmark Vantage moves and locks into position tightening-up the amount of 'throw' of the two control levers. This can be seen in a different YouTube video on the Exmark Vantage.
