At the start of 2026, YG Company delivered two sets of hydro mulch machine to Argentina. One solved the revegetation problem of dry pastures, and the other broke through the spraying bottleneck of steep high slopes. If you are in need of a reliable hydroseeder trailer for sale, these two cases are the best proof.【WhatsApp/WeChat/Phone】+86 13837122632

Case 1: Dry Land Revegetation for Ranch Owner Rodriguez
Customer Background & Challenges
Mr. Rodriguez owns a large ranch in central Argentina. Due to long-term drought and overgrazing, soil desertification became severe. Traditional sowing methods led to grass seeds being blown away by wind or washed away by rain, with a vegetation recovery rate lower than 30%. He urgently needed a hydro mulcher for sale to restore grassland quickly and efficiently.
YG Solution
We recommended the YG-HP4 hydro mulch machine for him. With water as the carrier, the equipment fully mixes grass seeds, adhesives, fertilizer and covering materials in the tank to form a uniform slurry mixture. After spraying, it forms a film layer on the soil surface to prevent rain erosion and seed loss. This trailer mounted hydroseeder can be easily towed by a tractor and move flexibly on rough ranch terrain.
Project Process
Rodriguez learned about YG through a friend’s referral. After two video calls and an online equipment demonstration, he placed the order. The key to successful communication was showing him construction videos of our equipment working in arid areas like Chile.
Application Results
Two months later, the ranch vegetation coverage exceeded 85%. Deep root growth greatly improved soil water retention.Customer Feedback: “This hydro mulch machine brings my land back to life. It is 10 times more efficient than manual work, and the grass grows evenly across the whole ranch.”
Case 2: Slope Greening Project for Landscaping Company Owner Garcia
Client background and challenges
Garcia’s landscaping company won a contract for an ecological restoration project on a mountain highway. The slope was 28 meters high, with a gradient over 65 degrees, and the soil was mostly gravel and weathered rock. Regular hydroseeding equipment either couldn’t reach far enough, or the slurry wouldn’t stick. Several suppliers he contacted earlier had machines with a maximum vertical lift of less than 30 meters, which couldn’t meet the job requirements.
YG solution
We recommended the YG‑146 (146kW / 199hp) diesel‑powered hydro mulch machine. This model has an 8m³ tank capacity, covers 210–320㎡ per tank, and allows spray thickness adjustment from 0.5 to 5cm as needed. Its key advantages: horizontal direct range of 40–50 meters and lead pipe vertical lift of 50–100 meters—meaning that even on a 28‑meter high steep slope, operators can stand safely at the bottom and use extended hoses to send the slurry precisely to the top. Plus, the diesel version needs no external power, making it ideal for remote mountain sites.
Case process
Garcia found YG’s website (https://ygconstructionpro.com/) via Google Search. At first, he doubted whether the YG‑146 could form a stable sprayed layer on the gravel slope. Our technical team explained the principle of soil spraying in detail: the built‑in mixing system (mechanical chain variable speed + horizontal shaft inclined paddle + circulating jet) thoroughly mixes binder, water‑retaining agent, seeds, and mulch into a high‑density slurry (max solid content 70%). After spraying, it forms a layer of “artificial soil” on the rough rock surface, which resists erosion and helps seeds germinate. To completely ease his concerns, we arranged a live remote demo showing the same model working on a rocky slope in Yunnan—the slurry was sprayed steadily onto a 30‑meter‑high slope and stuck firmly. Garcia decided to sign the order on the spot. Key details that closed the deal also included our promise to provide a Spanish‑language operation manual and one week of remote commissioning guidance.
Results
After the machine arrived in Argentina, YG engineers guided Garcia’s team through the first commissioning step‑by‑step via video calls. In actual work, the YG‑146 performed beyond expectations: each tank covered about 300㎡ (with a thickness of around 3cm), spray time was about 8 minutes (direct injection), and fuel cost was only about 30 yuan per tank—very cost‑effective. In less than two months, the once‑bare gravel slope was covered with lush grass, with roots deep into the sprayed layer, and it passed the owner’s erosion test. The client commented, “This YG‑146 hydro mulcher for sale helped us crack the toughest nut. Its range and lift data are completely genuine, and the diesel engine is super fuel‑efficient. If we have a bigger project next time, I’ll choose YG again!”
Daily Maintenance Tips for Hydro Mulch Machine
To extend the service life of hydro mulch machine, please follow the tips below: Rinse the tank and pipelines with clean water right after each use to avoid blockage caused by dried residual slurry; Check the wear of mixing blades and nozzles every week; Add grease to bearings and transmission parts monthly; Drain all water and store the equipment in a dry and ventilated place if it will be idle for more than one month.
