Komatsu XT445L-5

Komatsu's new XT445L-5 set high industry standards for Tracked Feller Bunchers with the following features:  Gull-wing engine hood service access, Increased lift capacity, Cab relocated to the left side, Rugged new undercarriage, KOMTRAX® telematics system, Powerful fuel-efficient engine, and so much more.


Gull-Wing Style Engine Hood

Gull-Wing Style Engine Hood

Gull-wing engine hood folds down providing an elevated service platform.
Hydraulically-actuated with backup manual hand pump. Robust design provides a secure footing with 500 lbs (227 kg) load capacity.
Offers excellent visibility and access to all engine-related components.
Provides full access to engine oil filter, air filter, fuel filters, coolant, DEF fluid and hydraulic filters.

Relocated Operator's Cab - Increased Track Visibility

Relocated Operator's Cab

State-of-the-art cab relocated to the left side. Tracks are now highly visible through the side door and boom side windows
- Larger door window has an “L-shaped” flat bottom
- Engine/pump compartment is set-back; top 2/3 portion is indented rearward

Rugged New Undercarriage

Rugged New Undercarriage

Rugged new Komatsu undercarriage provides longer service life due to:
- Heavier 8.5“ track chain links have a thicker bushing strap which is stronger at resisting "twist”
- Track rollers & idler bushings are made of high-density material
- New track sliders have a reduced angle providing 30% lower contact
- Final drives use a new triple labyrinth seal to protect from mud-packing
- Crawler Box improvements include:
~ Removeable track guards have larger roller side openings to reduce mud packing
~ Additional set of steps has been added to each crawler box

75% Greater Lift Capacity

75% Greater Lift Capacity

Significantly increased lift capacity at full reach vs. XT-3 due to improved boom & arm geometry and larger cylinders.
Provides better balance between boom lift & arm holding capacity.
Broad line of Quadco high speed disc saws available.
