The NSS Charger 2717 DB 6402734 combines a 27-inch wheel-drive burnisher, 350AH battery configuration, 1700 RPM pad speed, 80 pounds of pad pressure, Vac-Trac dust control, and a sulky setup for high-productivity large-area floor maintenance.

Features:

• Sulky Configuration – The key upgrade over the standard 350AH Charger 2717 DB, adding a sulky setup for greater productivity across large floor areas.

• 350AH Battery Configuration – Provides a high-capacity battery setup for extended cordless commercial burnishing.

• Wheel-Drive DB Design – Uses a dedicated drive motor to propel the machine, reducing operator effort compared with the pad-assisted AB configuration.

• Twist-Grip Throttle Control – Gives the operator convenient control of powered movement for easier operation across large areas.

• 120V Charging Configuration – Designed for charging from compatible standard commercial electrical service.

• 27-Inch Working Width – Covers a wide floor area with each pass for productive maintenance of large facilities.

• 1700 RPM Pad Speed – Provides high-speed burnishing performance for restoring gloss to compatible floor finishes.

• 80 lb. Pad Pressure – Combines substantial floor pressure with high rotational speed for effective polishing.

• Vac-Trac Dust Control System – Captures floor-finish powder generated during burnishing directly at the pad-motor shroud.

• Suitable for Concrete Polishing – Powerful motor performance makes the Charger 2717 suitable for use with compatible Twister diamond pads.

• 68 dB(A) Sound Level – Supports relatively quiet operation in commercial and institutional environments.

• Battery-Electric Operation – Eliminates propane exhaust, fuel handling, oil changes, and combustion-engine maintenance.

• Wide-Area Productivity – The combination of a 27-inch pad, wheel drive, and sulky setup is designed for efficient coverage of expansive floors.

• Lower Routine Maintenance Requirements – Electric operation reduces many of the service demands associated with propane burnishers.

• Designed for Large Facilities – Well suited for schools, hospitals, retail environments, warehouses, airports, and other expansive finished-floor areas.

The NSS Charger 2717 DB 27-Inch Walk-Behind Auto Burnisher with Sulky 6402734 is designed for facilities that want the high productivity of the wheel-drive Charger 2717 platform with the added efficiency of a sulky configuration.

It retains the core Charger 2717 DB features, including a 350AH battery setup, 27-inch working width, 1700 RPM pad speed, 80 pounds of pad pressure, twist-grip wheel drive, and Vac-Trac dust control.

Sulky Configuration

The primary difference between model 6402734 and the standard 350AH Charger 2717 DB configuration is the sulky setup.

The sulky is intended to improve productivity across larger facilities by reducing the amount of walking required during extended floor-maintenance routes.

It can be especially useful in:

• Warehouses

• Schools

• Hospitals

• Retail stores

• Airports

• Convention spaces

• Long corridors

• Other large commercial facilities

350AH Battery Configuration

Model 6402734 is equipped with a 350AH battery configuration.

The higher-capacity battery setup is designed to support extended cordless operation across large floor areas.

Actual operating time will vary depending on:

• Battery condition

• Floor condition

• Pad type

• Burnishing load

• Operator technique

• Facility layout

Wheel-Drive DB System

The Charger 2717 DB uses a dedicated powered wheel-drive system.

Unlike the AB model, which relies on the pad motor to help pull the machine forward, the DB uses a separate drive motor for propulsion.

This can provide:

• Reduced operator fatigue

• More controlled movement

• Easier operation over large areas

• Improved productivity

Twist-Grip Throttle

The powered drive system is controlled through a twist-grip throttle.

This gives the operator intuitive control over machine movement during operation.

120V Charging Configuration

The battery system is configured for 120V charging.

This makes it practical for facilities using compatible standard North American commercial electrical service.

27-Inch Working Width

The Charger 2717 provides a 27-inch / 69 cm working width.

The wide pad increases productivity by reducing the number of passes required across large open floor areas.

1700 RPM Burnishing Speed

The burnishing pad operates at approximately 1700 RPM.

This high-speed rotation is designed to restore the glossy appearance of compatible finished hard floors after scrubbing and routine maintenance.

80 lb. Pad Pressure

The Charger 2717 applies approximately 80 pounds of pad pressure.

The combination of substantial pressure and high pad speed helps efficiently restore floor-finish luster.

Vac-Trac Dust Control System

High-speed burnishing can generate fine floor-finish powder.

The Charger 2717 incorporates NSS’ Vac-Trac Dust Control System into the pad-motor shroud to collect debris as it is created.

This helps reduce loose dust left behind after polishing.

Concrete Polishing Capability

NSS identifies the Charger 2717 as suitable for concrete polishing with compatible Twister diamond pads.

This expands the machine beyond conventional floor-finish burnishing for facilities maintaining polished-concrete surfaces.

Battery-Electric Operation

The Charger 2717 DB uses battery-electric power instead of propane.

This eliminates the need for:

• Propane fuel purchases

• Fuel-cylinder storage and handling

• Engine oil changes

• Combustion-engine maintenance

• Indoor combustion exhaust during operation

68 dB(A) Sound Level

The Charger 2717 operates at approximately 68 dB(A).

Its relatively quiet electric operation can be useful in facilities where floor maintenance may take place during occupied or extended operating hours.

Professional Applications

The NSS Charger 2717 DB with Sulky is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Warehouses

• Airports

• Convention facilities

• Office buildings

• Government facilities

• Commercial cleaning contractors

• Finished VCT floors

• Polished concrete with compatible Twister diamond pads

• Large commercial floor areas
