I would love to have a bulb planter-sod plugger tool that would make a hole in the 2 1/2 to 3 inch diameter range.
As much as I hate to spray I guess my favorite tool is my battery powered backpack sprayer, I have to use it on my back for most of my beds with multiple rows in them, but for border beds with just two rows I can put in in my cart behind my riding mower and just cruise by while spraying.
I did get mine on sale much cheaper than listed here.
