Today a friend of mine came over (hi Jason! ) with his 2720 to work on a land leveling project with me. We removed some old raised bed garden plots and the plan was to cut down a ridge and make the entire area smoother. Between his 2720 to fit into some smaller areas near the house and my 5320 for the heavy grunt work, we were set. The Artillian forks made quick, simple work of removing old railroad ties, and the 5320 moved a lot of dirt with the loader.
Then, it was time to take the box blades and cut down the ridge. Simple enough, right? Sure! I started in one spot, Jason in another. We were doing well until a rock was discovered. Now, the rock shouldn't have been much of a surprise. I've had various trouble with them before, including destroying a subsoiler on my 5320 when I hung a basketball sized buried rock. I have another rock removal project in the works down near the driveway. It's just part of having a house on the side of a hill, you get some rocks.
The 2720 was cutting right along, when the box blade rippers hung our new discovery and stopped the tractor cold. I mean dead stopped, all four wheels spinning and going nowhere. He backed up, got away from the rock and everything was fine. Removing the rock was the next course of action, and it was clear that the 2720 was just a little too light for the job. I'm not slighting the tractor at all, it's a really great machine. Just a little light for unearthing boulders in one shot. We had a bigger tractor, so we dug out the rock a bit and decided to see if the 5320 would be any more successful at getting it out of the way.
I approached the rock from a different angle, in low range, low gear. The rock didn't seem to be too large, and not buried too deep, so the thought was we could hook it with the ripper teeth on my box blade and just pop it out of the dirt. Simple enough, right? We both watched in slow motion as the box blade teeth hung the rock, and then...the hitch supports on the blade twisted into a nice S shape , the blade tilted up and slid right over the rock.
Yeah. That didn't really work out so well. :empathy3: At that point it was decided that perhaps we should just bury the rock. This is a little clearer photo of the damage to the blade. It's actually not bad. The support arms are wrecked, but they're simple enough to fabricate and replace. I'm considering reinforcing them when I repair it, but overall this blade isn't super heavy duty so I don't know that it would make a big difference.
In any case, it was a great day hanging out with a great friend. The box blade was just collateral damage.
