Mini Skid Steer Loader: Ditch Witch SK650

The Ditch Witch SK650, available since fall 2005, is the company's newest mini-skid. Powering the machine is a three-cylinder, turbocharged Kubota diesel engine, developing 31 net horsepower at 3,000 rpm. The SK650 features four hydraulic pumps: two variable-displacement types for powering the travel system, and two gear types for the implement circuits. The travel-system control levers are pilot operated (electric-over-hydraulic) and, according to Ditch Witch, the design results in precise, low-effort control with minimal vibration.

The implement control lever is a joystick type, operating the loader's lift-and-tilt functions, and an adjacent lever engages the machine's auxiliary hydraulic system. Linkage between the auxiliary lever and a foot pedal on the platform allows the operator to control auxiliary flow to powered attachments with the pedal, thus freeing hands for maneuvering the machine and adjusting the work tool. The machine's auxiliary-hydraulic system, says Ditch Witch, delivers 20.9 hydraulic horsepower.

Ditch Witch also calls attention to a couple of the SK650's generous dimensions, such as its 81-inch lift height, and its 43-inch track-on-ground measurement, which, says the company, contributes to stability and low ground pressure. Supporting the track is the SK650's eight-roller undercarriage, which is maintenance-free. In fact, the machine has no grease fittings, using instead permanently lubricated bushings.
