According to John Deere, the new 724J, 744J and 824J wheel loaders are built to deliver optimal performance for their bucket size, resulting in faster cycle times and lower operating costs. Operating weights are 40,704, 51,196, and 57,339 pounds, respectively. A key feature of the J-Series is smart-shift technology. By continuously sensing speeds and loads and adjusting clutch pressures accordingly, the transmission delivers smooth shifts without any delay, Deere says. The loaders offer a spin-control system, which prevents tire spin when crowding the pile in 1st gear. Also, solid-state electrical distribution seals a significant portion of the components from moisture. Estimated list price: $219,000 to $330,000.
