What happens here

Chris clarifies the function of the brake pedals in modern payloaders. When either brake pedal is pushed, it triggers a 'transmission disengage' feature, automatically shifting the machine into neutral. This allows the engine to maintain high RPMs, ensuring that hydraulic functions (like lifting the bucket) operate at optimal speed even while the machine is braking. This is particularly advantageous for tasks like stockpiling, where quick and powerful hydraulic response is needed without driving through the brakes. He emphasizes that this is a feature of modern, load-sensing hydraulics, unlike older gear-driven pumps that required operators to hold the brake and hit the accelerator for faster lift response.

Goal: Understand how modern payloader brakes affect transmission and hydraulics for efficiency

What they say

Hide

move? Um, so we have two brake pedals on the floor. Um, they're both they both do the same thing. And then also an accelerator pedal all the way to the right. It's where your brake is on your car. It's your accelerator. So So it's just set up now. Is you got two brake pedals? Is one an engine brake and one a wheel bra? They're they're both brake They're both brake pedals. Um, we do have like what we call transmission disengage. So a lot a lot of guys if they're stockpiling, they'll they'll
