Tubeless Forestar

New, tubeless versions of the Alliance Forestar III 643 and 644 forestry tires from Yokohama Off-Highway Tires are proving themselves on cut-to-length (CTL) harvesters and forwarders worldwide.

“The new tubeless Alliance 643 and 644 eliminate all the hassling that comes with inner tubes—breaking valve stems, messing with flaps, and even just waiting for an inner tube when you need to be cutting timber,” says Terry Goodwin, National Forestry Tire Manager for Yokohama Off-Highway Tires America, Inc. “These new tires have a more durable sidewall, built-in rim guard and a reinforced, hexagonal bead bundle, so they don’t have to rely on an inner tube to hold the air.”

The tubeless Forestars fit on standard rims, Goodwin notes, so it is easy to switch from the tubetype designs.

Steel-belted construction, cutresistant compound, curb rib and buttressed lugs for extra durability, and an improved bead package keep CTL harvesters rolling no matter what the conditions are.

Tubeless Alliance Forestar III 643 sizes include 710/40-22.5, 750/55-26.5 and 780/50-28.5. Tubeless Alliance Forestar III 644 tires are available in 600/50-22.5, 710/40-22.5, 600/55-26.5, 750/55-26.5 and 780/50-28.5 sizes. Visit yokohama-oht.com.

Waratah Cutting

The new H423 from Waratah Forestry Equipment is designed to carry out a wide range of harvesting jobs from early to late thinnings, and even light regeneration harvesting. With outstanding multi-tree-handling qualities, a compact frame design and excellent power-to-weight ratio, the H423 masters fast and precise felling and crosscutting.

The H423 is well-suited for delimbing stems of all diameters. Its outstanding multi-tree harvesting qualities and excellent powerto-weight ratio take productivity to the next level.

Ideal for thinnings and other fellings where the tree diameter at breast height is 150-350 mm (613", the 955 kg (2,105 lb.), H423 features strong, fast feeding in a nimble design.

Additionally, the H423 boasts a 420 mm (16.5") tip-to-tip delimbing diameter providing ample range for superior delimbing—and when combined with its 580 mm (22.8") cutting capacity and optional multi-treehandling equipment, it is unmatched for productivity in varied diameter stands.

This new model features next generation hose routing from the boom to harvester head and well protected hoses to the feed motors, making interference from understory or limbs a thing of the past. Likewise, serviceability to the main valve is easier and possible thanks to a new hinged valve cover and improved access to greasing points. Visit waratah.com.
