The Nodwell is Canadian in origin and is the largest of the rubber tracked vehicles in use at Casey.

The Nodwell can accommodate up to 6 people whilst the cargo tray can carry loads of up to 4 tonnes.

Towing capacity is limited because of its rubber tracks, but the Nodwell can haul loads of up to 3 tonnes on suitable sledges.

The Nodwell is powered by a Caterpillar 6 cylinder, turbo after-cooled diesel engine, and transmits power to the tracks through an Allison MT 654 transmission. It is of cab/tray configuration and is also fitted with a hydraulic telescoping cargo crane.

The Nodwell is used specifically to support scientific and other field programmes. It is not a general usage vehicle.

Because of the complexity, a mechanic or suitably experienced operator must always accompany the vehicle on any journey.

A Foremost Pioneer, a similar tracked vehicle, is used at Mawson. However it has a smaller cab which can carry a maximum of three people. It is not used for any long distance field work, but primarily for cargo work in support of air operations.
