L.H.T Tractor (Milled Peat, Type III)
This tractor, fitted with attachment, is used for ridging the milled peat into the centre of the field.
The tractor is the half track type with front steering rollers.
The main frame is fabricated from standard steel angle and channel sections. The tracks are single chain cast link type with timber swamp shoes bolted on and runs on cast sprockets and intermediate supporting rollers. The front steering rollers are spoked with fabricated steel rims and cast iron hub and are mounted on stub axles on a pivoted axle beam which swings in the vertical plane. Steering is effected manually through worm reduction gearbox, drag link and track rod.
The tractor is powered by a water cooled diesel engine fitted with automotive type clutch.
The transmission consists of a speed step-up primary gearbox of special design, a standard agricultural tractor change speed gearbox and differential assembly with a chain reduction final drive between the standard trans¬mission unit half shaft and the track sprockets.
Since this tractor is used only for ridging operations during daylight hours no electric generator is fitted and the engine is hand started.
A hydraulic pump assembly is incorporated in the standard agricultural transmission unit and this is used to actuate the attachment hydraulic system.
