Bolt-on forks and trailer ball receiver for front loader bucket. I use these just about everyday, to lift, move, and position stuff. Would not be able to live where I live at my age without them.

Wood door shim to scrape food cooked onto pans. Free and gets off stuff scrubbies won't, without scratching the s** out of a pan using a metal one. Saves ruining wooden spoons doing the same thing.

Battery powered, brushless motor chain saw: i'm worn out before using up two lithium batteries, and get a lot more done with not expending energy pulling on a 2 cycle engine. Same for weedwacker, brush cutter and pole saw. Keep it sharp, works fine for this semi retired farmer, even after sitting idle all winter.
