The Vermeer 504R Signature Round Baler – 4' x 5', Twine is a variable-chamber round hay baler designed for producing consistent, high-density bales across a range of field conditions. Configured for twine tying, this Vermeer baler forms bales from 36 to 60 inches in diameter and 47 inches wide, allowing operators to produce compact bales for handling, storage, and transport. Its camless wide pickup, 540-rpm PTO driveline, standard moisture sensors, density gauge, and bale-shape indicators support efficient hay collection and dependable bale formation. The 504R Signature is suited to hay operations requiring a versatile baler with a 45-hp minimum PTO requirement and a recommended 55 hp.

Built for Flexible Round-Bale Production

The 504R Signature uses a variable-chamber baler design to produce round bales between 36 and 60 inches in diameter. This range provides flexibility for different crop volumes, handling requirements, and storage plans, while the 47-inch bale width delivers a nominal 4-foot bale format. The machine has a maximum bale weight of 2,000 lb, providing substantial capacity for demanding hay-baling applications.

Wide Camless Pickup

A 60-inch camless wide pickup collects windrows across the full tooth-to-tooth width. The pickup uses five tooth bars and 60 steel-coil teeth spaced at 2.83 inches, helping gather hay into the baling chamber. Standard gauge wheels with spring assist are included, supporting pickup operation in the field.

Twine-Tie Configuration

This product code identifies the twine configuration of the Vermeer 504R Signature. The twine-tie system uses a single arm to apply two twines, with adjustable spring-loaded tension plates for twine management. Storage is provided for four twine balls. This configuration is intended for operators who specify twine tying for their round-baling operation.

Monitoring and Operating Features

Standard moisture sensors, a density gauge, and bale-shape indicators help provide information during the baling process. The 504R Signature family also lists the Atlas control system. Round drive shafts and bearings are included as part of the baler design, and the 540-rpm, 80-degree CV driveline connects the baler to a suitably equipped tractor.
