The best-in-class Rehlko Command PRO® 41 hp engine becomes the technical protagonist of the first-ever world record attempt to mow the area of an American football field.

Louisville, KY — October 23, 2025 — Rehlko will supply the power behind Cutting History, an official attempt to set a GUINNESS WORLD RECORDS™ title for the fastest mowing of the area of an American football field (approximately 1.32 acres / 5,800 m²). The event will feature the Command PRO® 41 hp engine in a real-world challenge designed to measure performance under demanding, high-load conditions. The attempt will take place on grass standing at a minimum height of six inches, creating a test that reflects genuine field performance rather than controlled laboratory conditions

Command PRO® 41 hp: The Engine that Redefines Dominance

The Command PRO® 41 hp(999 cc), represents the most powerful engine in Rehlko’s lineup and serves as the technical foundation for the record attempt. Built for durability and consistent torque output, it features closed-loop EFI, advanced cooling, reinforced internals, and a service-first design aimed at maximizing uptime and reliability.

“Cutting a record is impressive. Doing it without the right power is impossible,” said Nino De Giglio, Marketing Communication Director at Rehlko. “With 41 hp of true, repeatable big-block performance and industry-grade durability, the Command PRO® 999 cc makes the difference between attempting a record and actually setting one. This is not just a stunt, it’s a technical showcase.”

The engine delivers best-in-class big-block output with optimized torque delivery. Its closed-loop EFI system provides instant load compensation and improved fuel efficiency compared with carbureted systems. The enhanced cooling package and reinforced internal components allow extended operation under high load, while its service-first design—featuring easy access points, a Clean-Spin™ dripless oil change system, hydraulic lifters, and advanced intake protection—simplifies maintenance and reduces downtime.

The 36 hp and 38 hp variants of the Command PRO® 999 cc engine are currently available, with the 41 hp version entering production in Fall 2026.

“Cutting History”: The World-First Mowing Challenge

Rehlko today announced Cutting History, a bold global initiative that will attempt the first-ever GUINNESS WORLD RECORDS title for mowing a full field — equivalent in size to an American football field (≈1.32 acres / ~5,800 m²) — in under one hour. To raise the stakes, the grass will stand at a minimum height of six inches, creating a challenge designed to prove real-world power, durability, and efficiency.

The attempt, planned for Spring 2026, will showcase the Command PRO® 41 hpengine as the true enabler of the record. With a professional ZTR mower provided and prepared by Rehlko technicians, the stage is set for a world-first performance that connects endurance, precision, and raw power.
