Abstract
A driveline assembly for equipment, such as a tiller, includes a pair of counter-rotating bevel gears supported on a wheel shaft and rotatable relative to the wheel shaft. The driveline assembly includes a first slider gear movable between a first position in which the first slider gear is engaged with a first bevel gear of the pair of bevel gears, and a second position in which the first slider gear is engaged with a second bevel gear of the pair of bevel gears. When the first slider gear is engaged with the first bevel gear, the first bevel gear becomes operatively connected to a rotatable tine shaft to rotate tines in a first direction. When the first slider gear is engaged with the second bevel gear, the second bevel gear becomes operatively connected to the rotatable tine shaft to rotate the tines in a second direction opposite the first direction.
