It took a few months, but we finally got to do the excavator demo today.
We had a Yanmar SV100 excavator. The dealer had put a valve on the machine to push most of the flow to the head. You could over ride this by holding a button on the right joystick, but I didn't use it much. If you used the button, you could move the boom a little faster. I used it when returning the boom to the drive position to move to another spot.
The head was the same as the model listed, but had a new rotor and tooth design that's due out later this year. I couldn't take any pictures of the rotor. The teeth were planer that had 25 hours on them and hadn't been sharpened.
Most of what we cut was heavy brush along a steep ditch on the side of the road. Some trees were mixed in up to 6" in diameter. For this application, there was plenty of power to run the head. Even on the 6" stuff (softwood) I could barely tell the RPM's on the head dropped even being pretty aggressive with the stumps.
I took out a 12" oak stump and 8" ash tree. On these larger trees, performance better than our T320 with carbide teeth.
Overall, I was pleased with the performance of both the head and the excavator with the exception of the reach. We needed about 6 more feet to accomplish what we needed to. Now I've got to research the reach on various excavators. We need to stay under 30K lbs.
I shot a time lapse video of the demo, but for some reason the lighting was so bad I just deleted it. It was a bright, sunny day so I'm not sure what happened.
