I constructed a sturdy grade beam and secured it with strong cleats for easy handling, allowing me to efficiently move large quantities of material. However, an unintended inward curl on the bucket, paired with pressure relief on the thumb, causes the bucket to gradually scrape the ground and lift the beam into the air, about 5 feet in front of the blade. This constant readjustment frustrates me – is it a matter of my skills, the controls, or something else entirely? According to the salesperson, there may be a solution in installing a cutoff valve on the bucket curl function hose, but they need to confirm with the manufacturer first.
I am seeking clarification on the setup described. When grading, is the stick moving towards you with the bucket's bottom edge scraping the ground and the teeth pointing towards the cab, while the beam's bottom faces you in the cab? It's important to be mindful of the pressure on the beam when pushing down on the stick, as this can cause the bucket and thumb to slip, potentially hitting the bottom of the beam and causing the teeth to dig into the ground.
Is it common for heavy equipment machines to have the bucket curled in and the beam in an elevated position, similar to the image provided in the link? Or do they typically look different? Check out the discussion on heavyequipmentforums.com for more insights on equipment configurations.
This 10k size version boasts a unique feature - a beam incorporated into its design. Positioned in an outward curl, the beam begins to arc upwards right as it nears the blade, creating a striking visual effect.
When operating the machine, it's important to simultaneously roll the bucket out and engage the thumb function. The stick moves in an arc, so you must adjust its angle in relation to the stick to maintain the same position on the ground. The easiest way to do this is by activating and holding the thumb function while rolling the bucket out. Keeping the thumb valve engaged for extended periods won't cause any harm; it ensures constant pressure between the thumb and bucket, allowing you to roll the bucket out without losing the beam. If you're in the Seattle area and need a demonstration, I'm available to show you in person.
I just realized that holding my thumb down could help with unintentional curling when manipulating the bucket curl/boom control. I've started using just two fingers and applying pressure at the thumb tip, which seems to work better. I wonder if holding my thumb down might decrease the power to pull/rake in? A few months ago, I used a rental unit for rough grading and didn't have this issue, although I did have problems with thumb bleeding and the beam falling out. This control has no play in it. It's a JCB 8040, which I've heard referred to as the "KIA" of heavy equipment - not sure if that's true. Despite some issues like fiberglass hood covers and hydraulic leaks, I have 270 hours on it and overall like it. The Everett Brim tractor folks are great!

Answer: 1. Why is my grade beam lifting into the air when using the bucket on my equipment? - The inward curl on the bucket, combined with pressure relief on the thumb, may be causing this issue. Consider installing a cutoff valve on the bucket curl function hose as a potential solution.
Answer: - The issue of the grade beam lifting into the air may be a result of the equipment controls and the configuration of the bucket. It is advisable to explore solutions like adjusting the pressure relief or installing a cutoff valve on the bucket curl function hose.
Answer: - To address handling challenges with a grade beam, ensure that the equipment setup and controls are optimized. Consult with the manufacturer or a salesperson for potential solutions such as modifying the bucket configuration or implementing additional control mechanisms.
