Sakai has released its SV544-1 Series vibratory single drum soil compactor.

The latest update to the 84-inch SV544 line, the SV544-1 introduces targeted powertrain improvements designed to enhance overall performance and efficiency on the job site.

The primary change to the SV544-1 is the integration of the Cummins F3.8 Performance Series engine, which now delivers 148 horsepower. This engine provides a 14% increase in peak horsepower over the previous 130-horsepower model at the same rpm.

Operators will also experience a 23% increase in peak torque, rising from 360 lb.-ft. to 443 lb.-ft., delivered 100 rpm sooner for improved responsiveness under load. Alongside this power increase, the SV544-1 offers improved fuel efficiency by an estimated 8% and features an ECO mode for further savings.

The engine also operates with reduced noise levels and provides an 8.2% reduction in CO2 emissions by utilizing the proven Cummins "Single Module."

"The SV544 has long been our best-selling model, known for its proven Sakai reliability, ease-of-use, and durability," said Brad Belvin, manager of sales and marketing at Sakai America. "With the SV544-1, we are improving that legacy by giving contractors more usable power, while simultaneously cutting fuel costs. It’s a practical update designed to support job site efficiency."

To support these mechanical upgrades, Sakai engineers have also implemented a simplified ECM harness for improved machine integration as well as other packaging changes. The SV544-1 otherwise retains the familiar features operators rely on, including straightforward analog controls that eliminate the need for failure-prone touchscreens or multifunction panels, Sakai says.

The machine continues to come standard with user-selectable traction control, a heavy-duty center hitch, and long-life isolators engineered to last up to 5,000 hours.

"We are proud that the SV544-1 is fully assembled in our Georgia factory," said Wes Shepherd, VP of operations at Sakai America. "As we prepare to celebrate 50 years in North America and 25 years of local manufacturing here in Adairsville this fall, producing this updated model is a testament to our team's ongoing commitment. We continue to combine legendary Japanese engineering with reliable USA-based assembly and support".

The Sakai SV544-1 Series is currently shipping to authorized Sakai dealers. The model line features operating weights starting from 24,405 pounds and offers up to 63% (32-degree) gradeability. Every unit is backed by Sakai's 3-year/3,000-hour warranty.
