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.
