Weighing in at 4-5 metric tons, the 650 and 750 articulated loaders represent Gehl’s expansion into the 60- to 80-hp size class. Both models have Tier IV-certified engine emissions technology: a Yanmar 64.4-hp engine on the 650 and a Deutz 74.3-hp engine on the 750. The Yanmar uses a diesel particulate filter after-treating system, while the Deutz engine uses a diesel oxidation catalyst after-treatment system, which allows users to choose their preferred emissions system.
The 650 and 750 models are the company’s largest wheel loaders and include standard convenience features such as a digital instrumentation display, Power-A-Tach Attachment Mounting System and a multi-function joystick. Digging and scraping performance is maximized through some of the highest breakout forces in their respective classes and front and rear locking differentials. A heavy-duty, oscillating articulation joint offers 45-degree turning angles to the left and right, and 10 degrees of oscillation in both directions for traction and maneuverability.
The bucket and tires follow a constant turning radius, so the rear tires of the loader follow the path of the front tires. Narrow machine widths allow access to tight, confined spaces that most skid steer loaders with comparable operating capacities cannot access. The “Z” bar-type linkage allows for mechanical self-leveling action in both the up and down directions, optimal bucket dump angles at the mid- and top-ranges of the lift path, mechanical return to dig, plus solid forward reach.
Proportional auxiliary hydraulics are standard equipment and utilized with a roller switch on the joystick. Detent and pressure relief are included to optimize attachment hook-up and performance. Two auxiliary hydraulic lines with flat-face couplers power a variety of tools and make attachment changes easy. Additionally, the 650 and 750 are available with a three auxiliary circuit option to the front and rear, including high-flow.
An open canopy ROPS is standard and a complete cab enclosure option is available, providing enhanced comfort and safety for all-day-long operations. Full 360-degree visibility is achieved by positioning the operator above the load for safe operation and attachment perspective. A multi-function joystick controls the lift arm, bucket, float, travel direction, differential lock and auxiliary hydraulic functions. An inching pedal allows operators to vary ground speed while maintaining a fixed engine speed to optimally run attachments while enabling precise machine speed control. — Manitou Group, www.gehl.com; www.manitou-group.com
