I needed:

Metric socket set.
Needle nose pliers.
WD 40
#2 phillips screwdriver

Helps: cordless impact wrench or drill.
Adapter to put sockets on wrench/drill.

A: Remove left panel. Held on with a bunch of 8 mm hex head phillips screw (It's a bolt head with a phillips star) and 2 12 mm bolts.
B: Remove hood. The hinge bolts have pins. Remove with needle nose. If you don't notice this the bolts are very hard to remove.
C: Radiator is held by two bolts under the bottom edge. Also pinned. I was able to get the left one undone. The right one remains stubborn.
D: Remove the 4 phillips head screws that hold the fan shroud.
E: Loosen the bolt in the centre of the adjustment pulley.
F: Unscrew adjustment screw. On mine this just came out instead of pushing the pulley carrier. Tap with hammer.

At this point I could swing the left edge of the radiator forward about an inch.

G: With several skinned knuckles I worked the new belt over two of the blades of the fan, then passed the the other side of the belt over the front face of the fan. Combination of turning the fan, tweaking with finger tips, and holding my tongue in the corner of my mouth. Fortunately my dogs are tolerant of my language.

Drive pulley on engine has a spline protruding from the front. A plate is in front of this. Remove plate. 2 more 10 mm bolts.

Put belt over drive pulley, then adjustment pulley. Tighten adjustment pulley. Tighten center nut of pulley.

Reverse the assembly.

My respect for Kubota declined over this. This is an aggravating amount of work for a common repair.

Replaced belt on my B2710 a couple of years back. Think all I had to do was pop off the side panels, had alternator off for bearing replacement (also reason for belt replacement) worked belt onto the fan blades and slowly rotated the blade till had old belt off and did reverse to get new belt over fan blade to pulley. Installed belt on to the fan pulley, alternator pulley after the crankshaft pulley. Tighten the belt, tighten the alternator bolts, snapped back on side panels.Think I used combo wrenches only. Sure big difference between the two. That is a lot of difference between the two models to me. My M6800 is even easier, no side panels.
