RB451 quick profile
Product Overview
Outstanding capacity, density, and innovation in every bale.
The New Holland RB451 is part of the Roll-Belt family, combining heavy-duty steel rolls with short, tough belts to form dense, square-shouldered bales across hay, forage, silage, and custom baling work.
Product Features
Engineered for clean pickup, strong feeding, and consistent bale quality.
Roll-Belt Bale Chamber
Heavy-duty steel rolls and short, durable belts help create fast core formation and tight, uniform bales in a range of crop conditions.
Durable Pickup System
Strong tine bars, intermediate reel supports, a heavy-duty steel roller, and tine windguard help deliver a clean sweep and positive crop flow.
Fast Net and Twine Wrapping
Available wrapping systems help hold bale shape and give operators flexibility for crop type, storage plans, partial bales, and custom work.
Precision Baling Tools
ActiveWeigh bale scales, in-cab density control, factory moisture sensing, IntelliBale automation, and FieldOps data management help operators make better decisions in the field.
SuperFeed and CropCutter Options
RB451 SuperFeed and CropCutter configurations use large undershot rotors to move difficult crops directly into the chamber with fewer interruptions.
Bale-Slice Availability
The available Bale-Slice system helps produce dense bales that are easier to feed and break apart for livestock rations.
Improvements
Next-generation Roll-Belt refinements built around uptime.
The RB451 platform focuses on improved productivity, stronger crop handling, smarter data, and easier daily service.
Application and Field Use
Built for real haymaking conditions.
Dry Hay
Create dense, square-shouldered bales for storage, feeding, and transport while preserving bale shape.
Silage and Baleage
Use moisture and density tools to help manage high-moisture forage quality during short harvest windows.
Custom Baling
Handle varied crops, field conditions, and customer preferences with flexible tying and precision data options.
Residue and Tough Crops
Available feeding packages help move bulky, slippery, or difficult windrows into the chamber smoothly.
A practical in-field workflow
Set density from the cab, monitor bale moisture and weight, follow the windrow with the pickup, wrap the bale tightly, clear the chamber, and keep moving while conditions are right.
