The mid-size 259D compact track loader from Caterpillar
Caterpillar is introducing (October 2013) three new Cat D Series Compact Track Loaders and three new Cat D Series Multi Terrain Loaders as well as two updated D Series Compact Track Loaders. The new and updated machines feature a completely new cab that enhances operator comfort and control, a new lift arm design for improved sight lines, and increased engine performance for greater productivity. The eight D Series rubber-track loaders range in rated operating capacity (50% of tipping load) from 2,800 to 4,650 pounds.
Mid size-frame models, as narrow as 66 inches, are the 257D Multi Terrain Loader (MTL) and 259D Compact Track Loader (CTL). Larger-frame models are the 277D and 287D MTLs and the 279D and 289D CTLs. These six models feature an electronically controlled 3.3-liter engine that meets Tier 4 Final (Stage IIIB) emissions standards. The Cat C3.3B engine provides 74 hp (55 kW) with 8% more torque and 6% improved fuel economy compared to the previous models.
The largest D series models, the 299D and 299D XHP CTLs, were launched in early 2012 and continue to be powered by an electronically controlled 3.8-liter engine, which meets Tier 4 Interim (Stage IIIB) emissions standards. The Cat C3.8 produces 98 gross horsepower (73 kW) for the 299D and 110 net horsepower (82 kW) for the 299D XHP, which powers an auxiliary hydraulic system producing as much as 40 gpm of flow at 4,061 psi to handle the most demanding powered work tools. The 299D and 299D XHP also receive the new cab environment as well as the new lift arm design.
