Well...it is done...delivery next Saturday. Ended up w/ a X354 (4 wheel steering) but only because there was still a couple of 2018 model year units still in inventory. Same specs as a 2019 but discounted additionally beyond the current Deere promotion. Simple, beefy mechanical linkages and zerks to grease them so we'll see how it goes. In the end, the cost differential wasn't bad at all over a 2019 X350.
Also picked up the core aerator and de-thatching attachments both pull-behind). Oh...and the brush guard, too.....even though I don't have much brush or landscaping. Tbh...I feel compelled to put a light bar on it for some reason.
