Consistent bale density due to increase in pressure.

Bale chamber and belt hold the key

In order to guarantee bale rotation in all conditions, all variable Fendt round balers have an Additional Drive System ADS. The four infinite belts and the lower drive roller are reliably driven by another drive roller in the top section. The wide wrapping angle produces powerful friction between belt and roller and permanently prevents slippage.

CPS provides constant pressure

For best results, it is vital that the bale density is properly controlled. All Fendt round balers with variable chamber therefore have the Constant Pressure System (CPS). This system increases pressure with increasing bale diameters to ensure a consistent bale density throughout the baling process. A consistent bale density is generated by achieving a balance between mechanics and hydraulics. As a first step, the belt tension caused here by large springs ensures a perfect start to the bale with a fast start speed and highly compacted inner layers. As the bales grow, the hydraulics take over the tensioning of the belts. Two cylinders connected to the closed hydraulic system proportionally increase the belt tension whilst the bales grow, so that the set density is reached. The outer layers are therefore perfectly compressed.

Very strong belts

Four infinite rubber and synthetic belts ensure an optimal grip on the crop, and apply plenty of pressure on the bales thanks to their exceptional traction. Two special synthetic fabric liners mean that the belts can withstand high tensile loads. These liners are produced separately with long excess lengths. This avoids any problematic joins.

At the start of the baling process, the pressure on the belts is transferred by the powerful springs.

Due to the intelligent tail gate suspension on the linkage, it moves downwards as the bale grows.

Four symmetrically arranged infinite belts shape the bales. The drive is powered by two drive rollers to transfer just the right force.

The two front belt-carrying rollers drive the belt. This double winding of the rollers means that the rotation is totally reliable for any type of bale.

The small start chamber ensures a reliable and early core rotation. This forms the basis for perfect bales.

Our bale chamber: The guarantor of perfect bales.

Firmly under control

The secret of the perfectly-compacted and even bales which are consistently compressed using Fendt round balers lies in the tail gate. It has been designed to be particularly robust, because it has to be able to withstand exceptionally high loads. The patented flexible suspension offers outstanding benefits.

Tail gate in motion

The tail gate on the Fendt round baler ensures perfect compaction throughout the baling process. At the start of the bail, the tail gate is the top position in order to forma clean core. As the diameter grows, the tail gate moves mechanically downwards. The tail gate slides to move the bales towards the rear. This reduces the pressure on the feed section. The output is therefore maintained at its optimum level, whilst the bales retain their perfect shape. The even pressure distribution also reduces wear on the components.

Best locking for the best bales

All Fendt round balers have a mechanically-locked bale chamber. The fact that the secure locking latch prevents the tail gate from swinging to the rear ensures that firm and optimally-shaped bales are created on a continuous basis. The bale density is controlled by the Constant Pressure System. It is formed by the hydraulic system fitted to the tensioning feeder rake and the two dual tension springs. The operating terminal provides a convenient way to set the desired bale density from the cab.

Stable guidance for short downtimes

Two stable cylinders are used to swing the bale chamber’s tail gate open and shut. All you need is a single-acting control unit. All of this makes for short discharge times, and a Fendt Vario tractor will enable you to smoothly and steplessly raise the working speed within seconds. Fendt tractors and round balers thus make a perfect team.

The mechanical tail gate valve gives the variable baler system the constant pressure required to produce exact bale diameters.

The bale ramp - which can be adjusted without using any tools - gives the bale the desired momentum, and prevents a collision between the tail gate and the bale ramp.

Quick bale ejection, very short idle times: Net ties, the straightforward bale ejector control, and the continuously variable Vario gearbox on the Fendt tractors, will all take your operations to the next level.
