A potato haulm topper is a piece of agricultural machinery used to remove the tops, or "haulms," from potato plants. The structure of a haulm topper typically consists of a frame mounted on wheels or tracks, with a rotating drum or cutter bar at the front. The drum or cutter bar is equipped with knives or blades that slice through the potato plant stems as the topper moves through the field.

The function of a haulm topper is to remove the tops of the potato plants in order to facilitate the harvest of the tubers. After the tops are removed, the potatoes are easier to see and access, making it easier and more efficient to harvest them.

The working process of a haulm topper involves attaching the machine to a tractor or other vehicle, and driving it through the field of potato plants. The drum or cutter bar rotates as the machine moves, cutting through the stems of the potato plants and leaving them on the ground. The tops can then be left in the field to decompose, or they can be collected and used as a source of mulch or compost.

It is important to use a haulm topper carefully and accurately, as cutting the potato plants too low can damage the tubers, and cutting them too high can result in excess foliage being left in the field, which can harbor pests and diseases.

Two main types of the potato haulm topper:

1. Compact potato haulm toppers are designed for use on small to medium-sized potato fields and are typically mounted on a small tractor or similar vehicle. These machines typically have two ridges, or rows, of blades or knives that rotate as the machine moves through the field, cutting through the tops of the potato plants and leaving them on the ground. Compact haulm toppers are relatively lightweight and maneuverable, making them well-suited for use in tight spaces or on hilly terrain.
2. Large potato haulm toppers, on the other hand, are designed for use on larger potato fields and are typically mounted on a larger tractor or similar vehicle. These machines typically have four ridges, or rows, of blades or knives that rotate as the machine moves through the field, cutting through the tops of the potato plants and leaving them on the ground. Large haulm toppers are typically more powerful and have a wider cutting width than compact haulm toppers, making them well-suited for use on larger, flatter fields.
