The New Holland Pull-Type Forage Harvester is a series of agricultural machines designed for efficiently harvesting forage crops. This document provides detailed specifications for several models, including the 790, FP230, FP240, 824, 3PN, 890W, 27P, and 29P, covering both the base harvester units and various attachments like cornheads and windrow pickups.

Function Description:

The primary function of these machines is to cut, chop, and process forage crops, such as corn or hay, into a form suitable for silage or animal feed. The "pull-type" designation indicates that these harvesters are towed by a tractor, which also supplies the necessary power through its Power Take-Off (PTO). The harvested material is fed into a cutterhead, which chops it into small pieces. Depending on the model and attachments, the material can then be further processed by a crop processor for finer chopping or conditioning, and finally blown into a trailing wagon or truck. Different attachments allow the harvester to adapt to various crop types and harvesting methods, such as direct cutting of standing corn or picking up pre-cut windrows of hay.

Usage Features:

Versatility: The modular design with various cornheads and windrow pickups allows the harvester to be adapted for different crops and field conditions. Cornheads are designed for standing row crops, while windrow pickups are used for pre-cut and dried forage.
Adjustable Length of Cut (LOC): The ability to adjust the LOC is crucial for producing different forage qualities, from longer cuts for certain silage types to finer cuts for specific animal feed requirements. The FP230/FP240 models offer flexibility by allowing knife removal for even longer cuts.
Power Requirements: The range of recommended and minimum PTO horsepower allows farmers to match the harvester to their existing tractor fleet, optimizing efficiency and preventing overloading.
Knife Sharpener: Built-in knife sharpeners (2" manual for 790, 3" manual for FP230/FP240) facilitate on-site maintenance and ensure consistent cutting performance.
Recutter Screens: The availability of multiple recutter screen sizes (5 for 790, 6 for FP230/FP240) provides further control over the final chop length and consistency, especially when using the optional crop processor.
Vertical Wheel Adjustment: The 4-1/2" (114 mm) adjustment on the 790 and 6" (152 mm) on FP230/FP240 allows for proper ground clearance and leveling, adapting to varying terrain.
Quick Adjust Shearbar: The FP230/FP240 models feature a quick-adjust, reversible, hard-faced shearbar, which simplifies maintenance and extends component life.
Crop Processor (Optional): The CropPro™ Crop Processor for FP230/FP240 models enhances forage quality by further processing the chopped material, often by cracking kernels and conditioning stalks, which improves digestibility for livestock. Its hardened ductile iron and steel shaft construction ensures durability.
Overload Protection: Features like shearbolts (824 cornhead) and slip clutches (3PN cornhead, 27P/29P windrow pickups) protect the machine's driveline components from damage due to sudden overloads or blockages.
Metal Detector (Optional): The Metalert® III electronic metal detector (standard on FP240) helps prevent foreign metallic objects from entering the cutterhead, protecting the machine and ensuring feed safety.
Spout Extensions: Optional spout extensions allow for easier loading into taller wagons or trucks.
Hydraulic Swing Tongue: An optional hydraulic swing tongue provides greater maneuverability and ease of transport.
Automatic Wagon Hitch: An optional automatic wagon hitch simplifies the process of connecting and disconnecting wagons.

Maintenance Features:

Built-in Knife Sharpeners: As mentioned, these allow for convenient and regular sharpening of cutterhead knives, which is essential for maintaining cutting efficiency and reducing wear on other components.
Reversible Shearbar: The reversible design of the shearbar on FP230/FP240 models effectively doubles its lifespan before replacement is needed.
Hardened Alloy Knives and Shearbar: The use of hardened materials for critical cutting components ensures greater durability and resistance to wear, reducing the frequency of replacement.
Driveline Protection: Shearbolts and slip clutches are designed to be sacrificial components that break or slip under excessive load, preventing more costly damage to the main driveline. These are relatively easy and inexpensive to replace.
Accessible Components: While not explicitly detailed for all components, the design of agricultural machinery generally prioritizes access for routine maintenance, such as lubrication, chain tension adjustment, and inspection.
Crop Processor Construction: The use of hardened ductile iron and steel shafts in the CropPro™ processor indicates a design focused on longevity and resistance to abrasive wear from processed forage.
Tire Options: The availability of different tire sizes and ply ratings allows for selection based on anticipated load and field conditions, contributing to tire longevity and machine stability.
Chain Drives: Many components utilize chain drives (e.g., auger drive, cornhead chain size), which are generally robust and allow for visual inspection and relatively straightforward tension adjustments or replacement.
