2026 Massey Ferguson MF RB 4180V Xtra 

Variable Chamber Balers 
Massey Ferguson RB 4160V and RB 4180V variable chamber balers share a common platform and produce bales up to 1.60m or 1.80m in diameter respectively and feature patented bale formation system with Constant Pressure System (CPS) that combines spring and hydraulic action producing dense and uniform bales.

Consistent bale density is essential for all baled products, and the new range of MF variable chamber round balers offer farmers the best solution due to their class-leading compaction, cutter and pick-up capabilities.

Features May Include: 

MF RB Exclusive Package

• The “Exclusive” package, available for MF Xtra Round Balers, adds Load Sensing or TIM functionality. This new package of features uses the tractor’s Load Sensing hydraulic connection, or ISOBUS – (for tractors equipped with TIM), to automate many functions and reduce operator fatigue. Productivity is also improved, as Exclusive balers benefit from automatic tailgate operation, automatic pick-up raising and lowering, and automatic knife slot cleaning. These balers also offer additional possibilities to utilise smart farming data documentation - including moisture & weight measurements.

High speed pick-up

• Higher operating speeds are possible with the Massey Ferguson camless pick-up design. With fewer moving parts, the camless pick-up is quieter, simpler and more reliable. Low maintenance and less adjustments save time and increase productivity. The pick-up system has five tine bars with each one being spaced only 64mm apart, providing higher capacity and a smoother even feed at high speed. The extra-long flexible tines protrude 13 cm out of the segment plates, equipping them for a record-volume-intake. On the Massey Ferguson round balers, the pick-up is positioned very closely to the rotor, therefore improving crop flow and reducing the risk of blockage.

Xtracut for optimum cutting performance

• Designed for optimum performance, Massey Ferguson round balers can be equipped with 13, 17 or 25 knives. Cutter units are fitted with the longest knives on the market, making sure that no material will pass through uncut. Xtracut 17 and 25 feature two sets of hydraulically operated knife banks with separate control from the cab depending on customer requirements. 

Hydroflexcontrol - Two stage protection system

• The first stage of Hydroflexcontrol allows movement of the front part of the feed chamber floor and will automatically prevent up to 80% of potential blockages and will keep you going without unnecessary downtime. Should a major blockage occur, stage two of hydroflexcontrol is activated by the operator, and is cleared by lowering the rear of the feed table floor hydraulically from the cab, allowing for material to easily pass through into the bale chamber, therefore minimizing downtime.

Bale chamber

• The bale chamber side panels are securely aligned during the production process with two large diameter tubes welded to the frame, providing a hardwearing and rigid connection for extended durability and better bale density control. Four durable, double-ply, seamless belts have excellent grip on the bale. With two stretch-resistant core layers made of a special synthetic material, the belts can withstand high loads when forming heavy silage bales.

Constant Pressure System

• The Massey Ferguson Constant Pressure System (CPS) retains pressure using two large springs during bale formation, thus maintaining the correct pressure from the core outwards. Once the core is formed, the hydraulic system takes over, which increases the pressure until the complete bale is formed. This keeps the bale surface pressure constant throughout the complete cycle.
