SF450 and SF438 are perfectly designed for professional users. The both machines provide comfortable operation and excellent cutting/collecting performance with high power engine, large capacity of HST and 1300L container capacity as well.
Powerful Engine]

With 48HP engine, SF450 is the most powerful outfront mower in ISEKI range.

The fuel tank capacity of both SF450 and SF438 is the largest (48L) in this product segment. Fuel tank is located in left side of fender, which helps easy access to refill the fuel.

To prevent grass from clogging on the screen of the radiator, the radiator fan reversely rotates every 5 minutes automatically. This function can lead to enough cooling capacity for producing full engine performance. Reverse rotating works automatically in case engine starts or it may overheat.

[Large capacity of HST]

Large capacity of HST pump and motors achieves faster traveling speed: max. 21km/h for SF450 and max. 19km/h for SF438.

SF450 and SF438 have the cruise control function for great cutting performance and comfortable operation. Cruise control keeps constant working speed without depressing HST pedal, which can ease vibration from pedal.
[Mower decks]

60-inch mower deck is available for SF450 and 54-inch mower deck is available for SF438 with grass collectors.
Mulching kit is also available for 60-inch mower deck as standard. Adding only one plate converts the rear discharge deck to the mulching mower deck.
The mulching plate can be attached by a bolt easily.

Mower deck can be flipped up without detaching universal joint for daily maintenance.
