John Deere has launched two new tracked waste handlers for landfill applications, the 950J and 1050J. Key features include a hydrostatic drive train, state-of-the-art cooling system and extensive guarding, making them well suited to the rigours of waste applications.
The 950J dozer has a 247 hp (184 kW) engine and weighs in at 58500 lbs (26.6 tonnes). The semi-U blade with trash rack has a capacity of 21.8 cubic yards (16.7 cubic metres) and is available with track pads from 22 to 26 inches (558 to 660 mm) wide.
The 1050J dozer has a 335 hp (250 kW) engine, and its operating weight is 81000 lbs (36.8 tonnes). The maximum blade capacity is 32.8 cubic yards (25.1 cubic metres) and track options range from 22 to 28 inches (558 to 711 mm) wide.
Guarding on both machines is extensive. The high ground clearance and smooth bottom guards keep the dozer riding over the trash without dragging and pushing it. All of the gaps were closed between the mainframe and belly pans, and cab and mainframe. Heavy duty tank guards protect the fuel and hydrostatic tanks from debris kicked up by the mainframe. Protective strips along the side of the mainframe prevent damage to the engine side shields and hinges. The turbocharger and exhaust manifolds are protected with thermal shields to reduce fire hazards.
The final drives have three layers of protection. The first layer is a bolt-on guard. Next is the stepped labyrinth to grind debris. The third layer is a dual-seal, oil-filled cavity. If anything damages the first seal, a light in the cab notifies the operator that the first seal has leaked oil. The second seal, which is still intact, holds the oil for the final drives.
They join Deere’s existing wheeled waste handlers, the 544J, 624J, 644J, 724J, 744J and its other tracked machine, the 850J.
