I have a Boxer 427 w/tracks. I bought it new about 2.5 years ago. I know it has made me money and as important it has saved my back. What has really made the machine even more useful and valuable is the 30 hp stump grinder attachment I bought last year. I bring the Boxer, BMG, and stump grinder to the job and it is very efficient setup. Recently I bought a used Swinger loader and root grapple. Now when there is the room I bring the larger machine but the mini still goes out each week.
