Kubotabooks ??
Curious, can you not get them from the dealer ?
parts drawings at Kubota and messicks.
I assume these are used and the seller lost the manuals ??
I have a PDF copy of the manual for B2781B (very similar just newer version) I can send you. I also have a series of 24 JPG pictures of the pages of manual for the B2733 quick hitch that someone sent to me. Not very convenient but worked for me when I needed a copy. Send me your regular email in a private message (conversation) and I can send them to you.
