Over a hilly route with the same load the mileage is reduced to 28. Maximum gradient ability is 1 in 7 under full load.
Plastics is used for the cab, which has a floor and back of wood. There are a cushioned seat and back rest for the driver. A loading space 8 ft. long and 5 ft. wide is afforded by the open-sided dairy body. Aluminium is used for the roof and valances, and wood for the floor. Aluminium flooring is an alternative at extra cost.
The enclosed series-wound traction motor is fan ventilated and controlled by a solenoid contactor giving four speeds forward and reverse: Lockheed hydraulic 11-in. by 2+-in, brakes are fitted, with two-leading-shoe units at the front. The mechanical hand brake operates on the rear wheels only. Tyres are 6.00-16 in.. whilst suspension is by rubber-bushed leaf springs. A double-reduction helical-spur and spiralbevel-gear differential is installed in the rear axle.

A pivoted fork supports cantilevers carrying the single front wheel, movement of the levers being controlled by 12-in.-long heavy-duty coil springs in tension.
Greater Range
Capable of 15 m.p.h., the Tonner is faster than its heavier counterpart and has greater range. Allowing for 150 stops, a range of 25-30 miles is provided when the standard battery of 259 a.h. capacity is fitted. The totally enclosed series-wound motor is mounted over the rear axle and rated at 4.25 h.p.
