Thanks for the update; I'm sorry it didn't work out for you (Especially with the drive) but I'm glad you'll be getting something you feel happy with.
If you haven't already found them,
coldwater tractors is about the same distance from you as Yakima, (in Hoquiam) but on your side of the Cascades. They're an advertiser here, and build loaders for basically anything you can find, as well as providing some opportunity to check out a variety of models.
As you found, it's awfully hard to beat loader controls on a joystick and a hydrostatic transmission for loader work. If you drive a skid steer, it will spoil you even more. They are all better than a shovel and wheel barrow though.
Some of the Yanmar tractors (the xx10 and xx20 series, and some US market machines) have what is called a Powershift transmission.
In practice, it works out like a clutched automatic transmission that is manually selected. It's a nice combination of a manual transmission and an HST, and basically splits the difference between them. It allows you to up or down shift to meet changing conditions without having to come to a full stop first, but doesn't give you the infinitely variable control within each speed range, only a few gears per range, but it's a good splitting arrangment. You can instantly reach neutral through the transmission, and not have to use the clutch, which can be an advantage to some. In point of fact, I think that once it's been started, those tractors could be run exclusively via the operators' hands, even if they were paraplegic, except for PTO control.
Good luck in your search! Let us know what you find, regardless of color/brand.
