I didn't know that the backhoe was removable on the Deere 110. I wonder how often that's done?
For my place, I bought a used 2WD New Holland 555E backhoe that's done everything I've wanted. I think it's better to have a dedicated digging machine, like a backhoe or excavator, then trying to do everything with just one machine. For almost 20 years, I just had the backhoe and a small 37hp tractor for mowing and 3 point attachments. I now have three tractors for doing farm things, but only use two of them. The small 37hp tractor has just been sitting for the last couple of years. I'm going to put the 6 foot cutter on it and use it for small areas, but with the 12 foot batwing on my bigger tractor, there's no rush.
Having the backhoe ready to go, anytime I need it is what makes it so useful. Trees fall down in the Spring from thunder storms. Animals pass away and need to be buried. Trenches need cleaning out so water goes where I want it from the storms. The backhoe is also very good at pulling me out when I get stuck!! But most of the time, I use it for digging out trees so I can increase the size of my pastures, of clear open areas for my fence. Trees too close to a fence will destroy it over time. My goal is to remove every tree that's 50 feet away from my fence. Having a backhoe means that I can do that when I have the time, and not have to change anything. I can mow one day, take out trees the next, or do both in the same day!!!!
