The base machine is unchanged to the VT7028 it replaces, and the VT7138 continues to run on the same six powered wheels (Mitas 900/60 R42), offers both four, six-wheel and crab steer, and is fitted with the in-house developed CVT.
The standard 32,000-litre slurry tank is the same, and the optional FlexTank (25,000-litre main tank and 7,000-litre collapsible version) continues to be available.
Main changes include the centrally-located exterior side panels and fenders, which like the 865-litre fuel tank and hydraulic oil tank, are made from polyester.
The new panels provide easy access for daily maintenance. On the one side, the engine oil dipstick and filling point are located next to the fuel pump, filter and diesel tank.
The panel on the opposite side of the machine opens to reveal the redesigned cooling package. The air filter, grease pot and air connection to clean the cooler are also close by. Below the air filter is a tool storage compartment and a clean water tank.
The cooling package has also been redesigned, and with the air-conditioning condenser folded out of the way, is easy to clean.
The PF12000 (12m³/min) positive displacement pump comes from the VT7028. New is the use of 10” (250mm) pipework throughout to optimise pump capacity, and the optional turbo filler at the top of the suction arm boosts slurry loading capacity to 16.0m³/min.
Available with Trimble or John Deere GPS-RTK with optional NIR and section control, the first VT7138-3’s will be delivered next spring.
