Rosco CSV Chip Spreader
The industry's most advanced variable-width chipspreader. Combine stepless 1' to 16' stone application, computerized Plus+1 CAN Bus aggregate gating, and a legal 8' 6\" width for permit-free hauling across Texas.
Engineered for Texas Roadways
Pavement Preservation Reimagined
Closner Equipment Co. is Texas's trusted distributor for pavement preservation machinery. The LeeBoy Rosco CSV (Chip Spreader Variable Width) represents the pinnacle of aggregate application technology. Built with a smaller total footprint to easily maneuver municipal environments and confined urban lanes, the CSV maintains absolute material distribution quality on rough, steep terrain and wide-open highway pulls.
Technical Superiority
Designed for Uptime and Precision
When aggregate costs rise and specs tighten, precise application determines profit. The Rosco CSV replaces mechanical estimations with digital accuracy and massive mechanical durability.
Plus+1 CAN Bus Rate Control
Computerized gate control system automatically monitors exact ground speed and adjusts gate openings in real-time. Maintains a precise, programmable aggregate application rate (lbs per square yard) during acceleration or braking.
1' to 16' Variable Spread Hopper
The variable-width spread hopper adjusts steplessly in motion from 1 to 16 feet. Highly flexible for narrow residential streets, cul-de-sacs, utility patches, or wide highway shoulders.
Permit-Free Transport Size
Designed with an 8' 6" legal transport width and an 8' 8" height (beacon retracted). Can be loaded onto a standard flatbed and hauled between jobs immediately without requiring costly wide-load permits.
Sliding Operator Console
The full operator station slides completely left or right on a robust platform, combined with dual joystick controls. Operator gains direct 360-degree lines of sight to haul trucks, hopper gates, and ground crews.
Reversing Smart Cooling Fan
A proportional hydraulic fan drive operates only as needed to save horsepower and reduce cabin noise. Features an automatic reversing cycle to blow asphalt dust, stone chips, and debris from the radiator core.
Dual 20" Hydrostatic Conveyors
Two independently operated conveyor belts run from 0 to 550 feet per minute. Feature floating mounts to reduce wear, and sonic sensors to monitor aggregate pile levels in the front hopper automatically.

Frequently Asked Questions
Detailed answers to key operational, hauling, and financial queries regarding the Rosco CSV chipspreader.
Why is the permit-free transport width of the Rosco CSV important?
Standard chip spreaders often exceed 10 feet in width, requiring contractors to secure wide-load escort permits, plan restricted routes, and incur high mobilization costs. The Rosco CSV folds down to a legal 8' 6" transport width and 8' 8" height, allowing it to be hauled permit-free on standard trailers. This saves hundreds of dollars in routing costs per move and allows immediate crew redeployment.
How does the Plus+1 CAN Bus system prevent aggregate waste?
Manual chip spreaders depend on operators opening gates to estimated sizes, leading to thick or thin stone layers that ruin the chip seal emulsion. The Rosco CSV's computerized CAN Bus system automatically monitors ground travel speed. It dynamically opens and closes the hopper gates to match acceleration and deceleration, ensuring the programmed application rate (e.g., lbs per sq yard) remains perfectly consistent.
Can the Rosco CSV handle rough or steep terrain?
Yes. Powered by a heavy-duty 275 HP Cummins QSB6.7 turbocharged diesel engine and supported by high-traction 385/65R 22.5 radial tires, the CSV delivers massive torque and pushing power. For severe Texas hill country paving or loose subgrades, contractors can specify the optional Hydrostatic Four-Wheel Drive (4WD) package to maintain stable tracking on steep inclines.
How does the proportional reversing fan reduce maintenance?
Chipping aggregate creates massive amounts of stone dust and airborne aggregate grit that rapidly clogs standard radiators, leading to engine overheating. The Rosco CSV incorporates a smart, proportional hydraulic fan drive that reverses air flow automatically at set intervals. This blows accumulated dust out of the cooling fins, maintaining low engine temperatures and avoiding costly mid-shift downtime.
