Both models come equipped with New Holland’s patented SmartLift technology, which not only aids in lifting the mower for transport but also helps in maintaining the correct cutting angle while in operation. This innovation contributes to even wear on the blades and enhances the overall lifespan of the equipment.

Moreover, the 451 and 456 are designed with user comfort and safety in mind. They feature easy-to-reach controls and ergonomic designs, which help reduce operator fatigue during long hours of use.
