A sand sifter apparatus includes a sifting head comprising that has a screen extending rearward from a leading edge of the screen and upward from an intermediate portion of the screen. The sifting head also includes a runner that is disposed below at least a portion of the screen and has a front section that is coupled with a front portion of the screen. A handle is coupled with a forward portion of the sifting head, where the handle is configured for a user to pull the sifting head forward over a bed of sand to draw sand over and through at least a portion of the screen that is elevated by the runner away from the bed of sand.

An articulated rake assembly attachable to an excavating vehicle having a bucket. The rake assembly has a rake mechanism adapted and constructed to retain material having a certain size. A reciprocating mechanism operationally connects the rake mechanism to the bucket of the vehicle, and is adapted and constructed to selectively reciprocate the rake mechanism with respect to the bucket, thereby selectively retaining material. The rake mechanism configurable to have either or both a push orientation and a gather orientation.

A striptill row unit includes a trash cleaner assembly, a coulter assembly, a knife assembly, a berm disc assembly, and a firming wheel assembly. The berm disc and firming wheel assemblies are independently movable between a raised transport position and a lowered field position. The knife assembly includes downwardly angled wings with leading edges extending substantially perpendicular to the line of travel of the row unit. Up/downforce systems are provided for various assemblies, with an independent actuator for each system. The berm discs are adjustable vertically, laterally, and angularly.
