Tigercat has introduced its lowest weight class harvesting head, as well as a new smaller class mulching head.
The new 544 harvesting head is designed 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 rigours of track carrier operating conditions. The head is equipped with four cast steel knife arms, and fixed front and back knives provide excellent delimbing quality.
Targeting trees in the 15 to 50 cm diameter range, the 544 has a maximum main cut capacity of 79 cm along with a 79 cm feed wheel opening, and a 76 cm maximum knife arm opening to handle the occasional larger tree.
Available with an optional 56 cm cut capacity top saw, the 544 is a great match for selective harvesting applications in mixed diameter hardwood and conifer stands. The harvesting head’s operating weight ranges from 1,700 kg with standard rotator and link up to 2,140 kg, allowing the head to be matched 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. As well, an efficient high-flow hydraulic system matched to Tigercat carriers provides excellent performance and outstanding fuel economy.
As 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.
Mulching head

Tigercat’s new smaller class mulching head is well suited to niche applications like fire mitigation and remediation.
Designed for the Tigercat 470 mulcher, the 4054-20 provides a complete end-to-end Tigercat mulching solution for narrow swath applications and lower horsepower carriers. The 4054-20 head has a smaller diameter drum, a 2 metre mulching swath, a lighter weight and a more compact design. Key applications include fire mitigation and remediation, as well as right-of-way and site preparation projects requiring a smaller, more agile machine.
The smaller size and lighter weight of the 4054-20 means it can work on carriers with less power, while retaining similar recovery performance to larger heads equipped on larger carriers.
Various carbide tools and hardened steel knife tools are available to suit a range of applications. The Tigercat designed bolt-on tool system is available for both the open face rotor and the feed control rotor.

Carbide welding on the skis provides extra protection from wear. The robust housing with reinforced side covers adds to the heavy duty build quality and structural integrity.
The drive system efficiently transfers power with no belt slip and reduced belt tension maintenance. Large, heavy-duty bearings and shafts ensure long life and high uptime. Numerous removable access covers allow easy maintenance of wear items and service points. The wear liner can be serviced in the field and does not require welding or rotor removal.
