For such a large beast the Stalwart is a formidable cross-country vehicle. Approach and depart angles are good, maximum speed on land is claimed to be 40mph, and trenches up to five feet wide can be tackled with impunity. Manoeuverability in water is good, steering being achieved by a combination of vectored thrust from the PTO driven twin Dowty water-jet propulsion units, and the road wheels. Speed through water is said to be about 6 knots. I'm glad you asked me that.
Suspension is independent all round, utilising torsion bars with parallel links.
There are a total of 22 telescopic hydraulic dampers. The engine is mounted at the rear, under the load deck, access being gained via six lift-off hatches. Drive is taken forward through a 12 inch Borg and Beck clutch, to the 5-speed primary gearbox, which incorporates PTO's for winch and marine drive. This diff can be locked, to fix all six wheels as one solid unit. Axle half shafts fitted with Tracta CV joints at each end join bevel boxes to wheel hub reduction gears.
