Benefits & Features
Grade With Ease and Accuracy
Improvements were made in various areas of blade control, using new technology features. Options such as Slope Indicate, Slope Assist and Stable Blade, offers the operator simple, intuitive control of the blade especially during finish grading and contributes to increased productivity and less operator fatigue.
Choices for any Application
The family of Small Dozers offers a choice of both track frames and undercarriages.
Track frames are available in two configurations:
XL undercarriage - where flotation and side stability are not extreme
• LGP undercarriage - for soft underfoot conditions where additional flotation is required
Undercarriages are available in two configurations:
• Sealed and Lubricated Track (SALT) Undercarriage
– Track is not bushing limited
– May require pin and bushing turn
• SystemOne™ Undercarriage
– Track is bushing limited
– Bushing rotates continuously
– Does not require bushing turn
– Designed to maximize the life of all undercarriage components
