Need some advice, I have a 4310 with a 48* Hoe I purchased for my house projects in 2003, landscaping, snow removel and moving dirt to build a garage at my house some day.** The problem is the machine has been great for many projects at the house and I have logged 120-130 hours . Most of them our loader and chipper hours, with 150 hours for my business* moving material and backhoe hours.This machine falls short for lifting* and digging for my buisness , I need to lift tower sections and heavy steel, dig electric ditches and foundations in mountain tops of rock and granite. I sub out a lot of* trackhoe work , but we still need a machine on site that is small to do the finish work and move material in the middle of the woods.I have been offered a good deal for trade on my machine for a 4120 with the 448 hoe or keep my 48 hoe with the new 4120.* This machine will give me the lifting capacity I need , but I think the 110Tlb will give me a great deal of durability I need to dig rock and rent breakers with the skid style attachment capability the machine offers.* I do love the small footprint my 4310 gives me at my house and the turf tires do not destroy the lawn or the driveway. I know I will miss the machine and moving a 4120 or 110Tlb will be more weight to move from site to site.Also keeping two machines is out of the question. I want to keep my* life simple , I have several buildings, employees,fleet vehicles and stuff to maintain now .* My latest is a 17 month old daughter that has been in the works for* 19 plus years and I want to spend more home life and less building businesses and more equipment.So,long story short what do you think 110tlb OR 4120?***
