Matt,
If you look at the picture above those pallets are brick pavers with 13 layers per pallet. What I do is take off 3 layers per pallet off and restack on an empty pallet. Not the best solution I know, but a quick one. We needed about three pallets of pavers for a job last week so we restacked a pellet with 9 layers on it and the others were 10 layers.
This did not take near as long as having to move an additional piece of equipment in to handle this job.
For a large portion of my work moving several pieces of equipment would be alot of trouble, buying larger equipment means you need a larger truck and trailer to move and it is costing you more money. So I can understand your dilema, and remember when I was considering a Cat 902 wheel loader and a 304 excavator but the two pieces of equipment that needed to be moved for each job made me leary. I will admit I wanted these two pieces of equipment to work out for me but they just didn't make sense.
I finally settled for the 8 in 1 tool, the 110 and having had it now for almost 5 years I can tell you that for my work it was the best all around machine to buy.
The 4520 is a different kind of purchase though, I bought it because I wanted it, I could have gotten by using the 110 for 3 pt work, having it though means I can leave the backhoe on most of the time. The tractor then is not encumbered by the loader, which is a real pet peave of mine.
All I can do for you is relate the experiences I have had and tell you what has worked for me. Hope you can figure out a combination that works for you.
