Hay baler. , water carrier

Sorry, I don’t know the proper name for these two items. I bought them at an old farm yard sale some years ago. The one item is a lift for hay bales up to the second floor of a barn. The other is a device for an animal to carry buckets of water. Hope that’s close. I am asking 35 dollars for both. I have been corrected on both accounts and have priced accordingly. The first is called a ‘single tree’. It is a wooden yoke for oxen or horses. The second item is a ‘hay harpoon.’ It is a heavy metal device to lift hay bails into a barn. Thanks to the person who got me straightened out. Sorry - the ‘single tree’ or wooden yoke for oxen or horses has been sold. The ‘hay harpoon’ is still here.
