Waratah debuts efficient H424 harvester head


Waratah Forestry Equipment recently introduced the new H424, a highly manoeuvrable harvester head specially designed for mid-sized wheeled and tracked machines. With an excellent power-to-weight ratio, the H424 makes quick work of second thinnings and early regeneration cuttings as well as processing or debarking applications.
“The versatile H424 harvester head is equipped to make jobs more efficient and productive,” said Brent Fisher, product marketing manager for Waratah. “A combination of features including a Performance Evo (PEVO) valve, Supercut 100S saw unit and highly durable mainframe make it great for amplified productivity and durability.”
Greater efficiency
The H424 comes prepared with a variety of features for enhanced efficiency. One such feature is a PEVO valve, which provides increased hydraulic oil flow and head control for higher productivity with less fuel and improved hydraulic efficiency.
For operations in slopes and mountain areas as well as improved trunk following, the H424 provides an improved backwards tilt range. The optional heavy-duty (HD) tilt frame provides added durability for tracked machine applications, while enhanced processing arms have an extra offset for simplifying picking from bunch piles and the ground.
As a mid-sized harvester head, the H424 aptly handles later thinnings and final fellings in addition to early regeneration cuttings. The new harvester can also expertly handle crooked wood and hardwood with its powerful and slip-free four-wheel-drive feeding.
One of the main features of the H424 is the new SuperCut 100S saw unit, which provides automatic chain lubrication and tensioning for improved performance and increased uptime. The H424 has a cutting capacity of 620 mm (24.4 in.), giving the head superb performance. Increased saw motor selection, compatibility with wide tail saw bars and a new chain release mechanism help ease saw chain changes.
The versatile H424 also handles processing and debarking. Its four moving delimbing knives along with one fixed top knife and one fixed back knife follow contours of the stem. Knife geometry and long cutting edges also help ensure excellent delimbing quality for a variety of stem diameters while the rear knife has improved colour marking application for identification of assortments.
Superior durability
Beyond efficiency, the H424 is a durable, consistent performer. Weighing in at 1,105 kg (2,436 lb.), the head’s sturdy mainframe provides high durability with a reinforced saw box.
Other features, such as new functionality in arm design, keep measuring arms sturdy and durable. The feed roller arms feature durable bearings, built-in feed roller guards, and strengthened cylinders and pins.
The improved access to the valve and grease points reduces servicing time while improved hosing to feed motors provides extra protection to help increase both uptime and durability.
“Efficiency is great, but our customers also need durable machines that are going to work consistently,” Fisher said. “The H424 is that harvesting head. It’s a reliable and consistent workhorse.”
The Waratah H424 is currently available to customers in Europe, the United States, Canada, Australia, New Zealand, Russia, Asia Pacific, Brazil and Latin America.
