Scag 52IN RC Extreme Slope Mower W/ 37hp Briggs Vanguard - SRC-52D-37BV-OG-EFI
The Scag RC Extreme Slope Mower SRC-52D-37BV-OG-EFI is engineered for safe mowing on extreme slopes, embankments, detention ponds, and hard‑to‑reach areas where a ride‑on machine would be unsafe. A hybrid system combines a 37 hp Vanguard BIG BLOCK EFI/ETC engine with Oil Guard driving a 7 kW alternator that recharges the onboard 9 kWh battery pack, which in turn powers the electric drive system and 52" cutter deck. The unit is fully remote controlled, so the operator can stay clear of hazards while maintaining precise control of travel, steering, and cutting functions.[web:143][web:147][web:158]
