I have a al540, adding 3” wheel spacer greatly improved the machine. It can lift incredible weight.
-pros- lifts like crazy, and doesn’t tear up lawns. Great for pushing over trees.
-cons-difficult to feed chipper with brush grapple. Weights a 8000lbs+_ so towing it daily sucks.
It goes out 1 a week or 1 every other week after I bought my ditch witch. It weight half as much so it easier towing, feeds the chipper much better, still room in trailer for logs and machine. It can also move dam big wood. If I were to do it again I would buy a mini first. Much more versatile machine. I have 1000hrs on my witch in 2 years, 450 hrs on my loader in 3.5 years.
