Ok, I had a chance to finally use it.
This was my first time using a 3pt hitch implement, so it meant removing the backhoe, which was also a first. I'm pleased that it all went well, though the hydraulic line was in a place I didn't like. I may have to revisit that.
Attached the 3pt hitch hardware went off without...well...a hitch. Even hooking up the box blade was much easier than I'd feared it'd be.
The target for use was my aunt's gravel driveway. I screwed up the courage to smooth where some potholes had formed. The scarifiers are a little interesting to use. There's, I think, 4 holes on them. At the "normal" setting, I think that they just BARELY stick out under the box. So that's kinda useless. So you can move them up a hole and they're then well clear. That leaves 2 settings for depth of digging. I chose the not-so-aggressive depth and got to work. Wow. It worked great. Broke up the gravel just wonderfully. I was only using it on a small section of driveway, so it only took maybe 10 minutes to have it all turned up. Then jump down, move the teeth all the way up, and use the box. Wow, that drags a lot of gravel around. It was fun trying to be gentle on the 3pt hitch lever to slowly let out the stored up gravel...but my neck sure didn't like looking behind me all the time. I hate being old. Then when I'd dragged the gravel all around (potholes no longer visible at all), I dropped the box and adjusted the top link so I could drag and smooth. And that worked great as well, but it was a bit of a pain adjusting the top link. I can absolutely already see the value of a hydraulic top link, but that's gonna be pretty hard for me to justify with only 1 hitch implement and not a gravel driveway of my own to use it on...
Feeling pretty happy with the result, I took on the next challenge. In the middle of their driveway, in front of the house, a very large rock was embedded in the driveway, about an inch or more proud of the rest of the driveway. It was clearly very large and very deep. I dropped the teeth again and gave some passes at it, in low, but not full speed. Wow, it stopped me cold. I then would give it some throttle and raise the box to try and pry the rock up. It just chipped at it. So I got down and dropped 2 of the teeth to the lowest setting. This proved kinda difficult because there's not much to hold onto and the teeth are quite heavy and smooth. I ended up holding it from below while I put the pin in. Not a problem really, but some kind of knob or something to be able to hold onto from above the tooth would be nice. I then took 2 more passes on the rock with the lower teeth, and up it came!
I did some more work but was hampered because a sudden downpour threatened to turn everything into mud, so I didn't do everything I wanted. I've come to the conclusion that working only a small section of driveway at a time is really annoying because you need to:
- Drop the teeth down and break it all up
- Pull the teeth up and blade it all around
- Adjust the top link to use the back blade to smooth it all over
And that's a lot of getting down and adjusting of screw links and all that. So, when I get the chance to go back, I think I'm going to try and do the entire driveway at once instead of a little section at a time, to minimizing all the adjusting.
I can't think of what else to share about it. My first box blade, so I have nothing to compare it to, but I was VERY HAPPY with what it allowed me to do.
