What happens here

After accessing the internal components, the belt drive system is showcased. The main pulley is connected directly to the engine, driving a triple-banded belt. This belt is also responsible for powering the hydraulic pump, which in turn operates the hydraulic motor that controls the feed rollers. The hydraulic pump's operations are electronically controlled through the chipper's operating system. Marty demonstrates how to adjust the feed roller speed using a designated knob; it should be set to slow for larger materials (like 9-inch logs) for efficient processing, and can be increased for smaller brush.

Goal: Understand the belt drive and hydraulic systems, and learn to adjust feed roller speed.

Yeah, we're going to check the belt out. We just took the There's four bolts that hold the cover on. Yeah, Zav, you want to grab the other side there? Let's lift this right off and set it right on the back of the pickup. So, this is the belt drive system. As you can see, main pulley off the engine. Uh, this is driving a, you know, triple banded belt. This also drives our hydraulic pump. The hydraulic pump is responsible for the operations of the hydraulic motor. Um, you know, it's plumbed directly into the valve. Um, and the valve, of course, is all controlled electronically through our operating system. Now, hit the clutch a couple times for me, would you? So, that's how you engage the valve. Yep. So, you're going to want to start it neutral and then uh give it about 25% throttle or so when the machine's running. Uh, the
