Agile and High-Performance, Horsch‘s “Leeb Cs” Mounted Sprayers Target Professional Contractors and Medium to Large-Sized Farms
The Italian market for low-crop sprayers generally favors mounted equipment due to its greater maneuverability and flexibility compared to trailed systems.
Fields are often fragmented and relatively small in size, making it more practical to use equipment that’s easy to transport and deploy rather than high-capacity systems that may be less versatile in terms of logistics. However, a typical drawback of mounted sprayers is the limited tank capacity, which requires more frequent refilling of the spray mixture, increasing both downtime and costs.
Bridging the gap between the agility of mounted sprayers and the autonomy of trailed ones is the “Leeb Cs” series by Horsch. The tank capacities range from 1,650 liters in the entry-level “1.4 Cs” model, to 1,950 liters in the mid-range “1.8 Cs”, and up to 2,250 liters in the top-tier “2.2 Cs”. These volumes—critical for estimating the potential treatment area—are complemented by an additional 400-liter clean water tank and a 15-liter handwashing tank.
New application
This setup offers significant operational autonomy, particularly when measured in hectares that can be treated with a single tank load. With application rates between 200 and 400 liters per hectare, which are typical for most herbicides and crop protection products used on low crops, the machines can cover from a minimum of 4 hectares (with the lowest-capacity model and the highest application rate) up to 11 hectares (with the highest-capacity model and the lowest application rate).
For users seeking even greater in-field autonomy, Horsch also offers two front-mounted tank models: the “Leeb 1.4 Ft” and “Leeb 1.8 Ft”, with actual capacities of 1,500 and 1,900 liters respectively. Combining the top-end models—“2.2 Cs” and “1.8 Ft”—results in a system with a total capacity of 4,150 liters. At a usage rate of 200 liters per hectare, this configuration can treat nearly 21 hectares, a figure typically associated with trailed sprayers.
Due to the large tank volumes of the Horsch “Leeb Cs”, specific design adjustments were necessary. To maximize compactness, the tank was designed vertically, and to reduce the leverage effect on the tractor’s rear lift, it was mounted closer to the tractor than conventional mounted sprayers. This results in improved stability and compactness, with operational speeds ranging from 4 to 20 km/h.
Maximum Output, Minimal Effort
The rotary pumps powering the hydraulic circuits of the “Leeb Cs” offer flow rates of 400 liters per minute at a maximum pressure of 8 bar, significantly exceeding the flow and pressure requirements typical of plant protection treatments. This allows the pumps to operate under minimal strain, even when feeding 15 to 30-meter boom widths—all of which are height-adjustable from 30 centimeters to 2 meters above ground.
These are boom widths commonly found in trailed equipment, yet without increasing transport dimensions. The booms are split into hydraulically foldable sections, ranging from six sections on the 15-meter models to 42 sections on the 30-meter versions, keeping the transport width to just 248 centimeters, well within legal road limits.
