Agricultural machine working on narrow track

摘要

The machine comprises a narrow-track tractor (1) with narrow-track single-axle trailer (2). A telescopic boom (5,6) and articulated arm are always at right angles backwards to the axis of the trailer (2). The trailer follows along or swivels with the drawbar (3) and hydraulic cylinder (4) through the articulated joint (12) with the tractor always serving as the counter weight. The tracks of the wheels (11) of the trailer can be widened for road travel or for lifting work. The boom can be fitted with root ball cutters or lift platform (14,16).
