Just an update: today I put the down payment down on a DK45 with filled R4s, KL1590 FEL with tooth bar, KB2385 BH, RB22-84 84" offset back blade, hitch/log skid, sun shade, grill/brush guard, and a 4" piston PTO log splitter. Soil implements like box blade, tiller, bush hog, etc can wait at this point until next Spring. One interesting thing is that the add-on cab kits from Kioti will apparently be out soon, and it looks like for around $2500 you can get a nice cab and heater for your DK. Not as fancy as the pre-built cab, but much less pricey, and nice for northern climes...
Delivery will probably be late next week, except for the log splitter and tooth bar which may be a week or two later. I'm looking forward to doing some serious work with this beast. Thanks to all for your expert help and advice. I'll post pics when I've got 'em.
