Kerian Machines, Inc.

Kerian Sizer

The Kerian Sizer uses a single set of rotating rollers, which gradually separate as they gently carry potatoes forward. The potatoes are thus sized accurately and consistently by diameter. The roller spacing is set by a pair of precisely machined spiral drives with increasing pitch along the length of the sizer. The extreme accuracy of the roller spacing allows precise separation of both long and round potatoes by minimum diameter, with quick adjustment possible by sliding a divider separating sizes. The Kerian Sizer comes in 13 standard models offering each grower a maximum value and a machine perfectly suited to their respective capacities and number of sizes.

656DD Windrower

Lockwood’s 656DD six-row windrower includes a double discharge, allowing a grower to dump potatoes in two different rows to improve harvester efficiency. Also available is the patented telescoping rear cross, which allows for either a left- or right-hand discharge. For better depth control, Lockwood has added pressure-sensing support wheels. Last but not least, experience industry leading visibility with a 656DD windrower also includes industry-leading visibility.

Air Harvesters

Lockwood has a fantastic solution for growers who grow potatoes in rocky soil conditions. Lockwood’s Air Harvesters are tough on rocks but gentle on potatoes. Using air for separation gently removes potatoes from rocks, minimizing bruising and maximizing cleaning. Many growers have experienced award-winning results year in and year out as Air Harvesters have helped enhance productivity and boost profits.

High-capacity capability allows harvesting of multiple rows, resulting in more acres harvested per day. Dual Crary blowers create optimized air flow, and a 60-inch vacuum chamber effectively lifts potatoes from rocks and other foreign material. Air Harvesters also include a rock box with an auto-dump feature and a can-bus system with user-friendly joystick control.


Safe-T-Pull, Inc.

Crop Shuttle

The Crop Shuttle is the largest, fastest and most versatile crop cart on the market. Choose from 36-, 46- and 56- ton capacity and discharge speeds up to 25 tons per minute. New for 2019 are multiple cleaning bed options that allow operators to remove tare and leave the dirt in the field. The Crop Shuttle is extremely versatile, allowing for use in multiple crops such as sugarbeets, potatoes, carrots, onions, red beets, cucumbers and even corn silage.

The Crop Shuttle is designed so that no PTO is needed to power the hydraulics. Its patented design has minimal moving parts and changing angles, meaning less buildup of debris while using less hydraulic power. The hopper rises into the air while unloading, creating the incline needed without a separate conveyor slowing down discharge and damaging crops.

Spudnik High-Capacity Storage System

In order to keep harvesting in the field moving forward, the Spudnik high-capacity storage system increases the efficiency of the overall harvesting season.

This high-capacity system will increase the storage rate up to 6,000 sacks an hour, allowing the grower to get more done in the critically short time frame of harvest.

Spudnik’s 1872 Even Flow Bin has a capacity of 600 sacks and a 72-inch elevator and bottom belt. A consistent, even flow of product is the key to the success of the entire high-capacity system. The hydraulically controlled back door sets the flow into the Eliminator and can be raised completely out of the way of the product for increased flow or to accommodate varieties with sensitive skin. The 42-inch Conveyor line moves the large volume of potatoes gently and smoothly through the storage to the 48-inch piler.
