The 6400 Hillsider serves a single all-important function: it brings unmatched traction, stability, safety, and productivity to slope mowing. With six-wheel drive for positive traction, a certified ROPS for maximum operator protection, and a low, low center of gravity, the 6400 means safety and performance on the most difficult inclines. True zero-degree turning jumps productivity in a way that no other slope mower can match. The 6400 walks over uneven, rutted terrain with no loss of traction, and then it trims close to buildings and highway guardrails with an excellent quality of cut.
