The Scag Turf Tiger is more powerful and efficient than ever
before with the KOHLER® Aegis® 31hp EFI (Electronic
Fuel Injection) engine. Experience tremendous power, productivity,
and fuel savings with this winning combination of engine and machine.
With its automotive-style radiator, closed-loop injection system, and heavy-duty air filtration
system, the Aegis delivers superior performance, custom made for
the most demanding conditions.
The Kohler Aegis engine features a liquid-cooling system that ensures
consistent flow and superior cooling to each cylinder. The results
are less cold-start friction, faster warm-up time, lower oil temperatures,
reduced engine wear, more power, and longer engine life. By integrating
the overhead valve design of other successful Kohler engines, this
engine offers optimal fuel efficiency, consistent running temperatures,
and quiet operation. Easy-to-access service points, a solenoid shift
starter, and a 3-year limited warranty* put the finishing touches
on this impressive package.
- Closed-loop Electronic fuel injection for maximum fuel efficiency
- Aluminum block with cast-iron cylinder liners
- Automotive-style radiator increases overall engine life and reliability
- Industrial grade air filtration system ensures maximum protection of interior engine components
- Dual air filters deliver maximum performance. The main filter traps dirt and debris while the inner filter prevents carburetor contamination during main filter servicing.
- Overhead valve design produces more power, improves fuel economy and cooling, and reduces oil consumption.
- Full pressure oil lubrication system with spin-on oil filter.
- Oil-pressurized valve lifters ensure that push rods remain in constant contact with rocker arms, eliminating valve adjustment; keeps valve train nearly maintenance free.
- Various user-friendly features: dual oil drains, easy-access oil fill, low-oil protection, in-line fuel filter
- Commercial grade solenoid shift starter means quick, reliable starts.
- Three-year limited engine warranty*
