I'll add and confirm the above posts...I tested out and decided to purchase a B2601 last weekend at a dealer here in Ohio. After discussing with the sales rep the options I wanted (3rd function valve, rear hydraulic remotes, wheel spacers, alternator kit), he said he would get them on order and let me know when things should be in.
Fast forward to yesterday, everything has been ordered...half the items are either shipped or due to ship out by end of next week. Others though (wheel spacers) are not due to ship until late November/early december! I emailed Messicks and asked if they had any in stock, and they also confirmed that the spacers won't be available until early december.
I thought about just having them deliver the tractor after the hydraulics are complete and doing the spacers myself, but the tires are going to be filled and I figured it is just as easy for them to put the spacers on before they are filled.
Patience is the is key right now...COVID has definately messed up supply chains and likely will for forseeable future.
