I cant quite make out what tractor and winch you have, looks like a B series Kubota, and Farmi brand winch.
I see you have your logging chains hooked to the notches on your winch, don't take this the wrong way, but I never hook my chains in those notches on the winch plate like Fransgard says to, I always leave the chain hooked to the keyhole slider, that way when I come to a hard place, I drop the load go a head with the tractor then winch the trees back up. I heard of some people hooking the chains to those notches and they break their logging chains.
