This is how I justified all my purchases. First the tractor - plow/repairs to my mile long gravel driveway. Clear the snow in my yard also. The FEL and bucket - move material on my driveway and anywhere on my 80 acres. The 3-point rear blade - driveway maintenance and creating trails anywhere on my property. My Wallenstein
chipper - I thin and chip my pine stands. 800 to 1200 small pines almost every spring.
Let "necessity" be your guide to what you need to purchase.
I did purchase a disk harrow. Land Pride DH1040. It is WAY to light and has proven to be worthless for me. One of these days I will get around to selling it.
