Vermeer RR140S Single Rotary Rake – 12.5–14 ft Raking Width [RR1188641]

The Vermeer RR140S Single Rotary Rake is a PTO-driven hay rake designed for efficient, consistent windrow formation across a 12.5–14 ft (3.8–4.3 m) adjustable raking width. Its single-rotor design places the windrow on the left side, while hydraulic rotor lift and a partial-lift function help simplify headland turns and transport between fields. With a robust 420 mm (16.5 in) cam track, walking tandem axle flotation, manual windrow adjustment, and standard highway lights, the RR140S is suited to haymaking operations that need dependable field performance and practical road transport. Product code: RR140S001. Manufacturer model: RR140s.

Raking Performance

The RR140S provides an adjustable working width from 12.5 ft to 14 ft, allowing the rake to be configured for different crop conditions and windrow requirements. The rotor has an 11 ft (3.4 m) diameter and uses 12 tine arms, each fitted with four double tines. Windrow width can be manually adjusted between 28 in and 47 in, while the windrow is positioned on the left side of the machine.

The 420 mm cam tracks support the rotary rake’s operating system, and the modular rotor design contributes to a practical configuration for haymaking work. Hydraulic rotor lift enables the rotor to be raised when needed, including during headland turns and transport operations.

Tractor and Hydraulic Requirements

The Vermeer RR140S requires a tractor with at least 27 hp (20.1 kW) of PTO power. Vermeer recommends 40 hp (29.8 kW) for operation. The tractor must weigh at least 1,043 lb (473.1 kg) and must be equipped with a drawbar for the rake’s hitch connection.

Hydraulic operation requires one single-acting hydraulic circuit. The hydraulic system requirement is 2,000 psi (137.9 bar) with a flow rate of 5 gpm (18.9 L/min). Confirm that the towing tractor meets these power, weight, hitch, PTO, and hydraulic requirements before use.

Transport and Flotation

For movement between fields, the RR140S has a transport width of 6.8 ft (2.1 m), a transport length of 16.4 ft (5.0 m), and a transport height of 3.9 ft (1.2 m). Total weight is 1,570 lb (712.1 kg), including a tongue/hitch weight of 820 lb (371.9 kg). Walking tandem axles help the rake follow field contours and provide flotation during operation. Standard highway lights support transport visibility.
