MTM,
Can you budget $1000 for a good boxblade? If so then keep an eye out for a used bb from a 210 landscape loader.
Something else to keep in mind, moving full buckets of heavy materials will require the larger rear ballast as discussed above. Moving lighter loads of branches and small trees you could get by with a lighter implement on the rear.
By the time you dug up all the stumps and cleared the debris out of the way you should be able to find a deal on a boxblade. Don't really need it until you have cleared the area enough to be able to use it.
About the machine choices mentioned imo the 110, M59 and L45 are all good choices for this work. I prefer the Deere pedal arrangement, that is a personal choice.
I could pull that off, I definitely wouldn't be purchasing one of them until spring/summer though as I'd have no use this time of year. What is the model number for a 210 box blade so I could look it up? What's the difference between those and the BB42 series? I would ideally get a nice BB42 but we'll have to see - I'm just trying to get a price guesstimate for how much this will all be. I'm really pushing to get the 110 now but the boss is insisting we wait till spring. I think I could make it happen, we'll see - got to keep the boss happy you know!
I too prefer the Deere pedal arrangement but I've been running the twin touch since I got my lawn tractor in 2000 so 11 years now. I'm sure I could get used to it but from the little experience I had on it it was more like moving your entire leg vs just your ankle, but maybe I was doing it wrong. As far as if you need a larger machine than a 110 the M59 is definitely a good option.
