We live down a single track lane, Mike. Get a lot of farm traffic. You should see the state of the Disco and our Mazda.
Actually it's not mine. Eldest grandson's. If I got in it, I could have trouble getting out again.
Get a trailer that will carry 1-1/2 ton or two. Twin axle. you never know how much more you will want to carry. One of those small plant trailers would be ideal.
That grease gun looks like the one Chris found in the barn on my last trip down south, on a visit to Johns place. That cleaned up ok and with a nipple connection of another gun I have, now resides in the C-81s toolbox for greasing in the finger bar.
The crank pin is not badly scored and may be repairable. I can't tell you spec and serial number as the have been painted over or lost. No balance gears fitted. Bore is ok so just new rings required. Need to price things before going any further. If going to be expensive it'll be a no go.
