Multi-functional Rotary
Snowplow

01Auger (ribbon screw type)

A ribbon screw type auger incorporating the latest in rotary technology is offered as a standard feature. It is also designed to prevent jamming by snow chains left on the road.

02Engine
High-torque engine produces enormous power.

Fills up a 10 ton truck
in 30 seconds

03Chute
Blows snow that has been gathered. Operator can adjust height and blowout angle at will.
04Snow cutter
Cuts through snowbanks and snow.
05Blower
The blades behind the auger rotate to blow up snow.

06Operator's cab

Engine rotation and speed are controlled separately with a pedal-lever drive mode for greater efficiency. Features cutting-edge electronic technologies including a vehicle monitoring system.

07Transmission

Features a proprietary power transfer system that distributes engine power efficiently between work and drive systems.

06Variable steering
modes to meet any plowing needs

Center pin pivot mode (rotary)
Front steering mode (i-piow)

When working with a rotary, the snowplow pivots on a center pin to enable changing directions easily even in narrow intersections.

Cuts cost by serving 2 roles.

09Grader
In action

Scrapes ice from the road surface, and levels the road after removing snow to create a smooth surface.

Clearing device replaced
in just 10 minutes for greater efficiency

Nichijo Manufacturing, a Kawasaki group company, is Japan's leading manufacturer of large rotary snowplows. It was the first in Japan to develop a hydraulic drive system for snowplows.
The HTR300M multi-functional rotary snowplow is Nichijo's latest and most cutting-edge offering. This snowplow allows easily replacing the clearing device at the front of the truck—it can be fitted with either a blade-type plow or a rotary plow. After pushing snow toward the road shoulder with a blade plow, it uses the rotary to blow snow off the road.

While these tasks used to be performed by two separate vehicles in the past, the HTR300M was "developed to enable efficient operation according to the amount of snowfall, ultimately saving costs," says Umeda.
Its simple detachable mechanism allows the operator to easily replace the clearing device in a short time. This is a big innovation in snowplows that is actually little known.
