Twin-engine configuration of the Schwarze A4 Storm regenerative air sweeper is driven by a Cummins QSF 2.8L auxiliary engine rated 74 HP to Tier IV Final. That unit turns a 30 inch closed-face turbine moving 12,000 CFM behind an 80 inch pickup head, feeding a 4.5 cubic yard hopper. Non-CDL municipal routes run daily, so the QSF 2.8 accumulates hours far faster than chassis mileage suggests.

Trailer-mounted dewatering pumps built by Cummins under the QSF4X4 and QSF6X6 names run on the QSF2.8 at 74 hp with 221 lb-ft of peak torque. The 4x4 moves up to 1,350 gpm against 150 feet of head; the 6x6 reaches 2,600 gpm at 104 feet. Heavy cast iron construction and continuous pumping duty in construction, mining and wastewater work load the 2.8-liter around the clock

MAX-Series cab versions of the ASV Posi-Track RT-75 keep the same Cummins QSF2.8 turbo diesel at 74 hp and 221 lb-ft, paired with high-flow auxiliary hydraulics up to 35.7 GPM at 3,300 psi. Attachment-heavy work loads the 2.8-liter continuously rather than in bursts. Operating weight runs 9,060 lb with rated capacity up to 2,800 lb depending on configuration.

Heavy-duty forestry and mulching work on the ASV Posi-Track RT-75 HD is carried by a Cummins QSF2.8 at 74 hp, delivering 221 lb-ft of torque through direct-drive hydraulic motors with no planetary drives to service. The 2.8-liter meets Tier 4 Final with a diesel oxidation catalyst that needs no regeneration or exhaust fluid. Three-panel hood and tilting cooler open the engine bay for service.

Compact track loaders take on hours faster than almost anything else on a jobsite, and the ASV Posi-Track RT-75 runs a Cummins QSF2.8 turbocharged 2.8-liter making 74 hp and 221 lb-ft. Tier 4 Final compliance comes through a diesel oxidation catalyst alone, with no regeneration, no sensors and no DEF to manage. Rated operating capacity is 2,650 lb at 3.6 psi ground pressure.

Carrydeck cranes working inside plants and refineries use the Cummins QSF 2.8L diesel, rated 55 kW with no DEF requirement, in the Grove GCD09. The crane lifts 8.1 tonnes on a 33.2 foot three-section boom and carries 14,000 lb on the deck. Confined-space industrial lifting means long idle and duty hours on the engine rather than road miles.

Pavement marking removal crews running the MRL Mini GrinderPro work behind a Cummins QSF 2.8 rated 74 hp, a four-cylinder Tier 4 Final turbo diesel. The engine carries an eight inch cutting head up to 13 inches wide plus a 1,500 CFM vacuum system and 60 CFM air supply on a 7,700 lb machine. Grinding, grooving and slot cutting load the unit continuously through a shift.

Rubber track carrier versions of the CME-45C, cataloged as the CME-45C/300, carry the same Cummins QSF 2.8 turbocharged four-cylinder at 65 hp and Tier 4 Final. Steel core reinforced tracks with embedded grousers carry the rig onto ground a truck cannot reach, and each track runs its own hydraulic motor and planetary drive off engine power. Rotary speeds reach 760 rpm.

Soil boring and environmental drilling on the CME-45C is powered by a Cummins QSF 2.8L rated 65 horsepower at 48.5 kW under EPA Tier 4 Final. Twin 68 inch stroke hydraulic feed cylinders sit in line with the rotary drive coupling, putting force straight onto the tooling. The same drill is configured on truck, trailer, skid, ATV, tracked carrier and helicopter-portable mounts.

Geotechnical drilling contractors running the CME-45B rely on a Cummins QSF 2.8 producing 65 hp from 171 cubic inches to Tier 4 Final. The four-cylinder turbo diesel feeds a heavy-duty clutch and four-speed transmission delivering up to 4,858 lb-ft of rotary torque. Mounted under 26,000 lb GVWR so no CDL is needed, these rigs run auger and coring work continuously.

Erosion control and hydroseeding crews running the FINN T170 work behind a Cummins QSF 2.8 rated 65 hp and 48 kW to EPA Tier 4 Final. The engine drives a centrifugal pump through an over-center clutch on a single shaft, moving 320 gallons per minute at 115 psi from a 1,500 gallon working tank. Highway, mine reclamation and large commercial sites all load this unit hard.

Oscillatory compaction on the Sakai SV414ND lets the operator switch between oscillation and vertical vibration in the same drum, useful in no-vibe zones near structures. The eight ton class, 67 inch roller draws on a Cummins QSF2.8 producing 74 hp. Sakai drives oscillation through gears rather than belts, so the engine sees a direct mechanical load with no belt slip absorbing shock.

Padfoot configurations of the Sakai SV414, sold as the SV414T and shell-kit SV414TF, carry the same Cummins QSF2.8 rated 74 hp at 55 kW. Maximum operating weight with padfoot drum and shell kit reaches 18,464 lb. Two frequency settings at 1,800 and 2,280 vpm let the operator match amplitude to the material, and the engine carries that load without a particulate filter or regeneration cycle.

Smooth drum site work on the Sakai SV414D pairs a 67 inch compaction width with Cummins QSF2.8 power at 74 hp. The roller works cohesive clay and silt as readily as sand, gravel and crushed rockfill, holding traction on grades approaching 63 percent. Roadway subbase, parking lot prep and commercial site work all load this 2.8-liter four-cylinder continuously rather than intermittently.

Single drum soil compaction in the eight ton class runs on the Cummins QSF2.8 across the Sakai SV414 series, rated 74 hp and 55 kW from 2.8 liters. Bore and stroke measure 94 by 100 millimeters in a water-cooled, turbocharged, direct injection four-cylinder. These machines are assembled in Adairsville, Georgia, and site prep work keeps them loaded through the full working day.

Tracked commercial pavers sold as the Dynapac FC1400C II carry the Cummins QSF 2.8 at 74 hp and 2200 rpm under EPA Tier 4 Final certification. Basic paving width is 2.60 meters, extending to 4.30 meters, with 400 tonnes per hour theoretical placement capacity. This model was superseded by the D14C using the identical power unit, so both names point at the same QSF2.8 installation.

Commercial paving crews running the Dynapac D14C tracked paver work behind a Cummins QSF 2.8 rated 74 hp at 2200 rpm to EPA Tier 4 Final. The machine lays a 2.60 meter basic width out to 4.30 meters at 400 tonnes per hour, with a 12 kW screed heating generator drawing off the same power unit. Dynapac also cataloged a Tier 3 QSF 2.8 at 54 kW on this platform.

Dual-engine Elgin Road Wizard sweepers carry a 5.4 cubic yard hopper and a 360 gallon water tank, with all sweep functions run off a separate auxiliary diesel in the 74 horsepower class. Cummins covers that node at Tier 4 Final with the 2.8-liter QSF2.8 and its passive catalyst. Because the rear engine runs whenever the broom turns, hour accumulation outpaces the chassis by a wide margin.

Elgin Eagle four-wheel mechanical broom sweepers drive the sweep system from a dedicated 74 hp Cummins auxiliary engine rated 55 kW at 2500 rpm. That is the QSF2.8, the only Cummins engine certified in the 49 to 74 hp Tier 4 Final node. Municipal fleets sweeping curb lines year round put heavy hours on the rear unit while chassis mileage stays low, and new surplus QSF 2.8 stock is held for them.

Wide-drum compaction on the Dynapac CP1200W pneumatic roller comes from an 81.9 inch rolling width backed by Cummins QSF 2.8 power at 73.8 hp. The 2.8-liter four-cylinder carries 221 lb-ft of peak torque and clears EPA Tier 4 Final using cooled EGR with a passive catalyst, so there is no regeneration cycle to stop a mat. New surplus QSF2.8 long blocks are stocked for this platform.

Rubber tire and asphalt compaction equipment in the sub-75 horsepower class is a core home for the Cummins QSF2.8, which delivers 73.8 to 74 hp from 2.8 liters with 221 lb-ft of peak torque. Hydrostatic roller drivelines demand strong low-speed response, and over 80 percent of peak torque is on tap early in the range. Tier 4 Final compliance needs only cooled EGR and a passive catalyst.
