I would have to say my most used is 2 ATVs, a trailer, and chainsaw equipment, pull behind sprayer, a spike toothed harrow, a pull behind spreader.
Not really equipment, but…The most enjoyable was my son to share all the experiences with, but he grew up and started his own family. I am hoping to get him back some day, and be able to do the same with the grandkids. Now I either do it myself, or when I need help, I have to negotiate with my wife to help her with stuff.
My dogs have always joined me in my projects, but now they are too old as well to walk back that far. But they use to be right next to me having a blast.
One thing to remember you will always have a list of projects that “need” to get done, but they can wait, sometimes life can’t. Don’t forget to have fun, and spend time with family and friends, and remember, they don’t have the same enthusiasm as you do.
