ladders on both sides, features a wrap-around tinted
windshield, has front and rear wipers and includes
many other features which contribute to improved
safety, visibility and comfort. The 4 comes
standard with an AM/FM cassette player and can
even be ordered with an optional 25,000 BTU
air conditioner.
Kawasaki and their dealer organization
offer comprehensive support and service
programs designed to keep you on the job.
PUTTING THE 4 TO WORK
Like all Kawasaki loaders, the 4 has a 35-year
heritage of strength and reliability. Dual lever hydraulic
control with a single lever option and single twist-grip
transmission control offer ease of operation.
The 4 comes equipped with a 3.25 cubic yard
bucket with a bolt-on cutting edge. A third spool valve,
control lever, linkage and line are available to handle
a number of attachments and extend the 4’s
versatility. Other buckets, Quick Couplers and
attachments are also available.
The outboard-mounted, four-wheel sealed wet disk
brakes are designed for long life and easy access and
overhaul. Standard spin-on filters, remote mounted
grease fittings and oil drain simplify maintenance.
The standard 20.5 x 25-12PR (L2) tires and optional
23.5 x 25-12PR (L3) tires use heavy duty three-piece
rims for easy servicing in the field.
