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
