Looks like you have plenty already. Some very nice saws and a nice tractor. Just need to add more to the mix over time. Over time, the proper tools and know how allow you to do more yourself and in less time. This gives you more money and time to invest elsewhere. It is a snowball effect. I have had my Craftsman hand tools for 23 years now and they have paid for themselves so many times over it is insane. If I could not do all the repairs to my 1998 Ford Taurus, we would have had to replace the car a long, long time ago.
At the end of waterfowl season, I completely stripped down my Benelli SBE, which is 5 months older than my Ford Taurus. Put the recoil spring, mag spring, recoil spring tube, mag end plug, bolt, and trigger assembly in the ultrasonic cleaner. Dragged the bore snake through the barrel a couple times. Everything came out nice and shiny. As I was putting it all back together, my wife came in, looked at all the parts all over the counter, and asked "What do people do that don't know how to do this stuff." My reply was, "They take the gun to the gunsmith when it no longer works and pay to get it fixed. Just like taking a car to a mechanic when it is not working right."
