Turf cutting machine

A turf cutting machine, comprising a frame, the frame being mounted on a rear axle that carries a pair of rear wheels and on a front axle that carries a pair of front wheels, wherein the frame carries a rigid cutting blade that extends horizontally beneath the frame, that is configured to cut below a turf at a selectable depth, and that is arranged between the rear axle and the front axle, and a motor that drives both the front wheels and the rear wheels and the cutting blade, wherein the rear axle and the front axle are connected to the frame in such a way that they are movable from a first position, in which they are at a maximum distance from the frame, to a second position, in which they are at a minimum distance from the frame, and vice versa, wherein the turf cutting machine comprises a transmission arrangement for transmitting motion from the rear axle to the front axle, or vice versa, the transmission arrangement comprising a transmission belt mounted between a rear axle pulley integral with the rear axle, and a front axle pulley integral with the front axle, and wherein the transmission belt runs on a plurality of deflection pulleys, which are arranged in such a way that a path of the transmission belt passes above the cutting blade, wherein the path of the transmission belt includes a first portion, going from the rear axle to the front axle and comprising a first substantially vertical section, extending from the rear axle pulley to a first deflection pulley, a substantially horizontal section, arranged above the cutting blade and extending from the first deflection pulley to a second deflection pulley, and a second substantially vertical section extending from the second deflection pulley to the front axle pulley, and wherein the path of the transmission belt further includes a second portion, going from the front axle to the rear axle and comprising a first substantially vertical section, extending from the front axle pulley to a third deflection pulley, a substantially horizontal section, arranged above the cutting blade and extending from the third deflection pulley to a fourth deflection pulley, and a second substantially vertical section extending from the fourth deflection pulley to the rear axle pulley.
