Product Overview
The SIVFORX S860LD is the ultimate flagship of our flail mower lineup - combining the S860L's PRO-grade configuration (15HP electric start, 860 mm extra-wide cut, 66 flail blades) with the S680LD's all-terrain track drive system (180 mm rubber tracks + rear stand-on platform). This is the definitive mowing machine engineered for large-scale commercial operations on the most challenging terrain.
15HP engine with one-key electric start. 860 mm cutting deck covering nearly a meter per pass. Sixty-six densely-arrayed flail blades delivering fine, uniform mulch. 180 mm rubber tracks holding firm on 30° slopes, mud, and sand - power, efficiency, and terrain capability all maxed out simultaneously. The rear stand-on platform preserves operator energy during extended shifts.
If the S680LD is your reliable partner on slopes, the S860LD is the ultimate weapon for large-scale commercial mowing on extreme terrain.
Founded in 2012, SIVFORX has shipped over 15,000 units to 30+ countries.

Key Features
The Ultimate Configuration - Four Flagship Technologies in One Machine
The S860LD is the only mower in the lineup combining all four flagship technologies:
|
Flagship Feature |
Specification |
Value |
|
PRO-Grade Power |
15HP + Electric Start |
Brush & thick grass domination, one-key ignition |
|
Extra-Wide Cut |
860 mm |
30% more coverage per pass, doubled efficiency |
|
Dense Blade Array |
66 Flail Blades |
Finer mulch, longer blade life |
|
Track Drive |
180 mm Rubber Tracks |
Slopes, mud, sand - true all-terrain |
15HP Electric Start - Big Power, One-Key Ignition
The 15HP engine delivers dominant power output through thick weeds, light brush, and rain-soaked heavy grass - no RPM drop, sustained efficiency. Electric start ignites this big-displacement engine with one key - zero exhausting pull-starts.
860mm Extra-Wide Cut - The Physics of Efficiency
An 86 cm cutting swath covers nearly 30% more area over the same walking distance. Combined with the S860LD's track drive that maintains steady travel speed even on slopes - all-day coverage far exceeds comparable-class machines.
66-Blade Dense Array - Tighter Coverage, Finer Mulch
Seventy-four percent more blades than standard 38-blade models means dramatically denser blade coverage. Finer, more uniform mulching. Lower load per blade - less individual wear, longer overall service life. Mulched clippings disperse evenly as ideal natural ground cover.
180mm Rubber Tracks - Conquer Extreme Terrain
Slopes (up to 30°):
●Strong grip, safe ascent/descent, no slipping
Mud / Wet Ground:
●Wide tracks, low ground pressure, no sinking
Sand / Soft Ground:
●Ample track flotation, continuous operation
Uneven Ground:
●Tracks conform to terrain, smooth stable progress
Stand-On Riding + 3F+1R Gearbox - Comfort Meets Control
Stand-on riding mode dramatically reduces physical fatigue during extended shifts. Three forward gears match different slopes and grass conditions; reverse gear enables safe tight turning on slopes.
10–80mm Adjustable Height - Fine Trim to Rough Clear
Tool-free rapid adjustment from 10 mm fine finish to 80 mm rough clearance - one machine, every application.

Applications
Mountain Ranches
Mountain pastures with steep slopes (15–30°) spanning thousands of acres - ordinary mowers either can't climb or are too slow. The S860LD's track + 15HP + 860mm triple combination is the only machine that simultaneously delivers "gets there" and "gets it done." Stand-on mode keeps operators safe and efficient on hillsides.
Wetland Large-Scale Pastures
Riverside, lakeside, and rain-season saturated large pastures - wheeled equipment sinks, narrow-deck machines are too slow. The S860LD's 180 mm wide tracks float over wet soft ground while the 860 mm cut covers ground fast. One machine, two pain points solved.
Large Commercial Orchards
Thousand-acre hillside orchards - steep slopes, vast area, fallen branches and stones on the ground. The S860LD is the only machine in the lineup fully adapted to this scenario: tracked climbing + debris-proof flail blades + wide-cut efficiency.
Highway & Railway Embankment Maintenance
Large-area embankments along highways and rail lines - steep grades, uneven surfaces, mixed vegetation. The S860LD's 30° climbing capability + 66-blade cutting power + 860mm efficiency is the optimal solution for these environments.
Government Large-Scale Ecological Maintenance
River levees, nature reserves, national parks - demanding the ultimate combination of terrain capability, efficiency, and reliability. The S860LD is an industrial-grade solution engineered for national-level projects.

Customer Success Stories
Case 1: Mountain Sheep Ranch - New Zealand
Customer: Sheep ranch on mountainous terrain (10–25° slopes, 3,000 hectares), New Zealand
Quantity: 8 × S860LD
Application: Mountain pasture height control and weed management
Client Feedback: "Our pastures are across mountain terrain - mowing was our biggest challenge. Wheeled mowers slipped on slopes; small tracked mowers were too narrow and slow. The S860LD is the first machine that solves both problems simultaneously. The 860mm wide cut covers ground fast. The tracks hold 25° slopes as steady as flat ground. 15HP has plenty of power - New Zealand grass grows dense and thick and the machine pushes through without hesitation. Electric start and stand-on mode make a huge difference for our workers."
Case 2: Mountain Coffee Plantation - Colombia
Customer: Specialty coffee growing group (terraced mountain slopes, 15–30°), Colombia
Quantity: 12 units
Application: Inter-row and terrace-ridge mowing across terraced coffee plantations
Client Feedback: "Our coffee is grown on terraced mountain slopes. Weeding between rows and along ridges is an enormous workload. The S860LD is the only machine that works efficiently on this terrain - tracks move safely between terraces, 860mm width clears an entire row in one pass. Flail blades handle fallen coffee branches and stones without any issue. Mulched clippings return naturally to improve the soil. This is the key piece of equipment for our mechanized plantation management."
