engines that provide the torque you need to power through tall
grass and rugged environments.

dial lets you adjust
the cutting height
in precise 1/4”
increments.

the cutting height without leaving your seat. Simply

FOLDABLE ROPS
The ROPS on the Z400 Series
mowers meets ISO 21299
specifications to ensure safe
and efficient operation. The
ROPS easily folds down to allow
the mower to pass under low
obstructions, as well as permits
easier storage in a garage or shed.
24" Rear Tires
Big tires mean a softer ride.
LOW PROFILE TIRE
The Z400 Series' new wide low-profile
tires not only look good, they provide
better traction for all types of mowing
tasks. They also have a larger footprint
that reduces ground compaction as
well as turf damage during turns.
