The new 544 is Tigercat's lowest weight class harvesting head for track harvesters.

Based on the proven 534 design, the 544 is a three-wheel drive head with triangulated wheel arm geometry. The chassis, covers and tilt frame are designed to handle the rigors of track carrier operating conditions. Four cast steel knife arms, and fixed front and back knives provide excellent delimbing quality.

Targeting trees in the 6-20 in. diameter range, the 544 has a maximum main cut capacity of 31 in. along with a 31 in. feed wheel opening, and 30 in. maximum knife arm opening to handle the occasional larger tree. Available with an optional 22 in. cut capacity top saw, the 544 is a great match for selective harvesting applications in mixed diameter hardwood and conifer stands.

Operating weight ranges from 3,760 lb. with standard rotator and link up to 4,720 lb., allowing the head to be mated to Tigercat H822 and H855 series carriers with standard or telescopic boom sets.

The hydraulically actuated measuring wheel promotes positive contact and reduces component wear. Diameter measuring on the wheel arms and front knife arms provides accurate measurement. An efficient high-flow hydraulic system matched to Tigercat carriers provides excellent performance and outstanding fuel economy. Optional 360 degree continuous rotation with through-tip hose routing and robust, stable wireless communication is available on select carriers. Various rotator, feed motor, feed wheel, knife arm, and wheel arm choices are available to tailor the 544 for specific applications.

For maximum productivity and performance in eucalyptus processing applications, the 544 debarking package includes several features to increase productivity and performance. The feed wheels and the wheel arm geometry are designed for debarking, spiraling the trees during feeding for better performance. The feed motor sizes are tuned for high demand and productivity. Unique front and back knife geometry provides comprehensive tree coverage.
