This case follows João, owner of an 800-head dairy farm in Paraná, Brazil. His two manure storage ponds suffered from thick, hardened sludge and crust. Old dredging equipment often clogged and failed to clear deposits, risking nutrient leakage and odor issues. Instead of building new ponds, João found the YG-900 dredging robot. After an on-site demo, the machine crushed solid crust and pumped manure slurry steadily. Its output hit 200 m³/h, far exceeding the old unit. The liner stayed intact, and dredged waste was separated and recycled as organic fertilizer, restoring pond storage capacity efficiently. Do you have a similar situation?

Before July, 2026
The Dairy Ponds Became a Growing Problem
João runs a large dairy farm in Paraná, Brazil, with around 800 cows. Behind the milking parlour were two effluent ponds, each about 4 meters deep and holding around 40,000 m³ of dairy manure slurry in total. Years of accumulation had created a hard surface crust and dense, low-water-content sludge underneath. A previous dredger struggled to enter the pond and frequently clogged, leaving much of the sludge untouched. At the same time, João faced pressure to control nutrient runoff, reduce odors, and maintain enough storage capacity. Building new ponds would have required significant time and investment, so he began looking for a more suitable dredging solution.
July, 2026
Searching for a More Powerful Dredging Solution
João spent several weeks researching YG dredging equipment for sale and comparing slurry pumps, floating dredges, and long-reach excavators. His main concern was that many conventional systems were designed primarily for water or relatively fluid sludge, while his ponds contained hardened dairy manure and fibrous material. He needed equipment that could both break up the crust and pump the resulting slurry. A farming cooperative introduced him to YG Machinery and its YG dredging robot. The recommended YG-900 featured a front crushing auger, 900 mm dredging width, 4-inch pump outlet, remote control, and a high-pressure water system, making it suitable for the conditions João described.
August 11, 2026
YG Conducted an On-Site Demonstration
In early August, João requested a demonstration before making a purchase. On August 11, he arrived at the YG dredging robot factory, where YG staff demonstrated the machine at a nearby pond. Unlike João’s previous dredger, the machine continued operating without the repeated clogging problems he had experienced. The technicians also adjusted the operating speed and water pressure according to the pond conditions, allowing João to see how the equipment performed in his actual working environment.
September, 2026
The YG-900 Started Full-Scale Dredging
João placed his order on August 13, choosing the YG-900 dredging equipment together with the high-pressure water kit and remote-control system. The equipment arrived in early September, and YG technicians helped his team launch and operate the machine. The YG-900 broke up hardened manure crusts and converted the material into pumpable slurry. According to the case, the unit maintained an output of about 200 m³/h, while the previous system managed around 20 m³/h under good conditions. The remote control also allowed the operator to guide the crawler cleaning robot around the ponds while keeping the hydraulic station on the bank.
After September 2026
Pond Capacity Restored and Waste Reused
After two weeks of operation, João inspected the HDPE pond liner and reported no cuts, tears, or scuffing. The dredged material was sent directly to a centrifuge, where solids were separated from liquid. The liquid was reused in the pond, while the dry solids were transported away for composting into organic fertilizer. The project helped restore the capacity of the existing ponds while addressing manure management and odor concerns. João also began sharing the YG dredging robot with neighboring dairy farmers and recommended requesting a demonstration to evaluate equipment before purchasing.

What João Tells Other Farmers After He Used YG Dredging Equipment
João is now a vocal advocate for YG. He’s spoken at two local dairy meetings. He’s shown videos of the robot working. He’s even invited neighbouring farmers to see it in action.
“If you are looking for dredging equipment, don’t just buy a pump,” he says. “Ask about crushing. Ask about dredging width. Ask about remote control. Ask about the liner. If the supplier can’t answer those questions, walk away.”
He now tells other farmers looking for dredging equipment to request a demo. “YG sent a demo unit to my farm before I bought anything. That’s how confident they are. They didn’t pressure me. They just showed me it worked.”
He also appreciates the support. “The technicians stayed until we were comfortable. They showed my workers how to run it. They gave us a maintenance schedule. We’ve had zero problems.”
