Embodiments of the invention provide a table-free technique for detecting all temporal and spatial memory access errors in programs supporting general pointers. Embodiments of the invention provide such error checking using constant-time operations. Embodiments of the invention rely on fat pointers, whose size is contained within standard scalar sizes (up to two words) so that atomic hardware support for operations upon the pointers is obtained along with meaningful casts in-between pointers and other scalars. Optimized compilation of code becomes possible since the scalarized-for-free encoded pointers get register allocated and manipulated. Backward compatibility is enabled by the scalar pointer sizes, with automatic support provided for encoding and decoding of fat pointers in place for interaction with unprotected code.

A harvester for root crops such as beets is provided which preferably provides continuous flow of root crops from a header, along a transfer assembly, through a processing run, and to an elevator assembly. The harvester can be configured to include or accommodate interchangeable header assemblies having different numbers of rows and / or row spacings. The transfer assembly can be of a floating type and helps to provide an even distribution of beets to the grabrollers. The processing run includes full-length cleaning grabrollers disposed parallel to the direction of travel. Modular elevator assemblies can be provided to further enhance harvester versatility. Such an approach includes interchangeable ferris wheel and scrubber chain elevator assemblies. An improved scrubber chain elevator assembly can be used which has a wraparound scrubber chain design. A pivoting tank conveyor for evenly filling a holding tank can be included. Large diameter carrier wheels on a single axle positioned for improved balance, flotation, and maneuverability typically are important basic characteristics of the harvesters.

A towable apparatus adapted for the separation of rock, stones, or debris from topsoil, having a stationary, non-vibrating sifting screen. A hydraulically powered conveyor belt with paddles pushes the soil across the sifting screen. The system provides features to assist prevention of machine jamming by large debris. A method of use is also disclosed.

A fully-adjustable lightweight trimmer attachment assembly (10) broadly comprises a wheel (14), a rod (16) extending from the wheel (14), and a mounting mechanism (18) for rotationally mounting the rod (16) to a trimmer (12).
