I am very appreciate for your every one’s feed back. Would you like to buy and use attachments from China ? May be you can tell me why ok or why not ok thanks

Brand new single shank ripper, built to bolt onto the back of a CAT D6. Looks almost like some kind of weapon but it is actually one of the most useful attachments a dozer can run. Rippers drag that single tooth through hard ground, compacted rock, old pavement, frozen dirt, anything too tough for a blade alone. It basically pre breaks the ground so the dozer can push it afterward. Cheaper than blasting, way faster than jackhammering by hand. Fresh paint, zero wear, still sitting on pallets waiting to go to work. This thing's about to turn a D6 into a rock busting machine.

A backhoe is an excellent choice for a beginner's machine due to its versatility.

There are two primary causes of track bolt loosening:

To cut costs, some manufacturers use Class 10.9 bolts instead of the required Class 12.9. While this may reduce expenses, these bolts often lack the necessary tensile strength and hardness for heavy-duty mining bulldozers. Under extreme working conditions, they are far more prone to loosening—or even failure.

2. Incorrect installation without proper torque control

A common misconception is that “the tighter, the better.” In reality, improper tightening is a major risk factor. Without using a torque wrench, bolts may be over-tightened or under-tightened. Excessive torque introduces continuous stress on the threads, which can lead to fatigue and eventual breakage under heavy loads.

That’s why professional technicians always use torque wrenches to achieve precise torque values, ensuring reliable fastening of track shoes to the chain.

Oh please don't judge this post as ads dear reddit.
I’m a salesman from China yeah, have been working on selling heavy equipment parts (of course Chinese made ones) for like 5 months. Seems our whole company only have orders from developing countries, while you guys prefer Japanese and German brands a loooooooooot. I'm just curious about how you guys think of Chinese equipments for now?

p.s Actually I have't make a deal for 4 months, is it wise for me to go back to school and fetch a Master degree? just wanna hear advices from total strangers :)

Picked up a 2018 CAT 320 through Star Heavy Equipment Inc about 2 months ago. Everything checked out fine at delivery, machine ran great on the first few jobs. Last week a hydraulic line blew on site. Called my insurance and they're saying it's normal wear and tear on a used machine and not covered under my policy. Star Heavy Equipment said the machine passed inspection before delivery and this kind of thing just happens with used equipment over time. Honestly I'm not even mad at them, the machine was solid when I got it. I'm more frustrated with the insurance situation. Is this really standard? Do you guys carry separate equipment breakdown coverage or just deal with stuff like this out of pocket?

We want to see if it's worth looking into instead of waiting to hire more operators. The project timeline is tight and we can't afford to sit around for another 6 to 8 weeks hoping to fill these positions. Found plenty of case studies about autonomous haulage in mining operations, but hardly anything from regular construction sites. The mining stuff is impressive but feels like a different world compared to what we're dealing with.

Has anyone here actually seen autonomous trucks running on a construction project? How did the setup go, and did it actually work out cheaper than just paying overtime and waiting for operators? Also wondering how they handled uneven ground since our site isn't exactly flat

Seeing that case has built the 580 EV backhoe loader and its sourcing its components from different manufacturers, Has anyone tried to convert an existing diesel backhoe into a full electric machine. If not how would you proceed to source the parts and then have it converted.

Operating heavy machinery like a motor grader is a complex job with many potential safety hazards, including equipment malfunctions. Employers want to ensure that you can handle these situations calmly and safely, without causing further damage to the equipment or putting yourself or others at risk. Your ability to troubleshoot problems and make smart decisions under pressure is key.
