About this file

This document is a technical specifications document for a Plot Research Combine procurement.

The combine must be a specialized agricultural harvesting machine designed for plot research with a 120 hp minimum diesel engine (4.5L minimum, Tier 4 emission standard), 40-gallon fuel tank, 5-gallon DEF tank, and three-speed hydraulic ground drive. Key performance requirements include a 55-bushel minimum grain tank with 18 liters per second unloading capacity, 4-wheel drive, hydraulic power steering, and a reversible cooling fan. The machine must not exceed 21.5 feet in length, 10.5 feet in height, 9.5 feet wheelbase, or 15,000 pounds in weight. Safety features are mandatory, including an OSHA-certified closed cab for two people, emergency stop mechanisms, fire extinguisher, and comprehensive lighting systems.

The threshing system requires a drum/straw walker configuration with hydraulically adjustable concave clearance, threshing cylinder speeds of 260-1,600 rpm, and a minimum 540 Nm torque for high-moisture corn processing. The combine must include two interchangeable headers (approximately 1.5m and 2m) with hydraulic floating capability and active feeding belts. A specialized weighing system with Mirus software integration must collect weight, moisture, and test weight data with capability to store plot weights and bag samples. Delivery to Stoneville, Mississippi includes on-site inspection, three days of manufacturer training (including header change procedures), two-year warranty, metric tool kit, and parts availability for overnight U.S. shipment. The combine must feature a 4-camera system, air ride seats, fully integrated multifunctional armrest controls, and simple electric/hydraulic systems for local mechanic serviceability.

Specifications

Plot Research Combine

Safety Features

• Closed cab with working area for minimum of two people

• Ladder to reach engine platform

• Railing on top of combine

• OSHA certified cabin (must provide OSHA certificate)

• Fire Extinguisher

• Emergency pedal in cab to stop machine from moving

• Emergency stop for header (grain table).

Warranty, Training:

• Onsite training by manufacturer’s technician.

• 2 Full days of training, including header change and adjustment of machine

• 1 Full day set up and training onsite.

• 2 years of Warranty on combine.

• Delivery to Stoneville, MS and inspection of machine on day of arrival with customer and manufacturers representative.

Basic machine:

• minimum 120 hp diesel engine

• minimum 4.5l diesel engine, minimum tier 4 emission standard

• minimum 40 gal fuel tank and 5 gal DEF tank

• Three-Speed hydraulic ground drive

• Hydraulic Parking Brake

• Front axle with one central drive motor and mechanical differential lock. The differential lock is needed to pull the combine in mud.

• Minimum 55bu Grain tank with hydraulic unfolding auger of minimum 13 height

• Grain Tank unloading through minimum of two augers in grain tank.

• Unloading of Grain Tank of 18L per second or more

• Hydraulic power steering

• Ladder that does not interfere with border rows while harvesting. We would prefer one that is concealed into the side of the combine during operation

• 4-wheel-drive

• Reversible cooling fan to keep radiator clean during harvest to prevent overheating.

• Front light, rear light, unloading auger light, grain tank light for harvesting in low light

• Rain Protection for Cyclone (needs to open or remove itself in harvest mode).

• Road Lights including indicators.

Cabin

• Fully integrated multifunctional armrest (for all buttons and switches) in driver’s seat

• Camera system with 4 cameras at following positions: weighing system, rear, straw walkers, cyclone

• Air Ride driver seat

• Air Ride passenger seat

• A/C, heater, headlights, security glass, windshield wipers, interior and exterior lights

• Indicators, horn, and lights for road use

• adjustable steering column (inclination as well as height)

Cleaning and Threshing System

• Threshing Drum/Straw walker system

• Concave clearance must be hydraulically adjustable

• Synchronized threshing system and straw walker system to improve clean out.

• Threshing cylinder speed adjustable between 260-1600 rpm

• Minimum Torque of 540 Nm on threshing cylinder for high performance threshing in high moisture corn

• Minimum threshing cylinder diameter 450mm and 800mm channel width

• Heavy-duty Concave and Standard Concave (Soybeans, etc)

• Concave Wrap Angle of 135°.

• 2-step cleaning surface/sieves with minimum of 23 sq ft cleaning area to ensure clean samples.

This includes 21 sq ft straw walkers to separate trash from seed.

• Hydraulically driven cleaning fan with quick adjustment from cabin, RPM of 450 – 1800

• Fuel Tank and Turbines need to pivot out for fast and easy clean out of entire machine

• Sieves for corn, soybean and wheat

• Distribution/straw Chopper. This is the system that chops the trash and spreads it over a wider area instead of a pile.

Feeder house:

• Chain Feeder-house to ensure high capacity in high moisture conditions. This prevents clogging of the seed auger.

• Easy Feeder-house dismounting within 15 min

• Quick Coupler to ensure all hydraulic hoses can be removed at the same time via a compact coupling system instead of removing hydraulic hoses individually

Cutting Platform (Header or Grain Table)

• Two headers are required so that in the future we can shift to different row spacing or combine can be used in other crops in future. One is approx. 1.5 m and the second is approx. 2m.

• Emergency Stop for Header.

• Hydraulic Floating Option to cut close above ground without constantly adjusting header

• Hydraulically adjustment of reel (vertical and horizontal)

• Brush Bars on Reel

• 6 bar reel

• Crop Lifters

• Sickle Bar, Auger, Crop Divider

• Active Feeding Belt behind entire sickle section to actively feed crop towards auger

Weighing; sampling:

• Weighing system to collect weight, moisture, test weigh.

• Weighing System needs to slide out completely for easy moisture calibration without operating combine (engine turned off for safety during calibration)

• Industrial Tablet with Mirus weighing system software including field plan

• Switch to deliver seed to either to the weighing system or to the grain tank

• Activation of weighing system cycle after plot ergonomically via joystick button

• Weighting system (including software and weight bucket) can store plot weights, take physical sub-samples, or bag the plot seed in the cab.

Combine Size:

• Length: Max. 21.5 ft. This is the max size of our plots.

• Height: Max. 10.5 ft

• Wheel Base: Max. 9.5 ft. Wheel base can be decreased if required to accommodate different plot size in future.

• Weight: Max. 15,000 lbs.

Maintenance:

• Operator Manual and parts book

• Tool Kit with metric tool and fire extinguisher. We do not have many metric tools

• Simple electric and hydraulic system to ensure local mechanics can diagnose and repair mechanical and electrical issues.

• Combine model parts needs to be available in the U.S. for overnight shipment to our location

• Hydraulic operations over belt solutions to reduce down time, combine should not have more than 7 belts, self-tensioning drive belts preferred
