We just released a 29hp Command PRO EFI repower engine spec configured specifically for Exmark Lazer Z and Toro Z-master ZTRs that were manufactured between 1998 and 2011 with horizontal shaft carbureted Kohler Command PRO engines. Our Command PRO EFI engine utilizes the industries only Closed-Loop EFI system. Now standard in the automotive industry, Closed-Loop EFI provides greater reliability, optimal power, turn-key startability, and maximizes fuel efficiency. Commercial landscapers who have switched from a carbureted engine to a comparably powered Kohler Command PRO EFI engine have saved up to $600 a year in fuel costs while experiencing up to 25% better fuel economy.
