The PRIMOR GII 110.1 Polydrive is the embodiment of a new generation of straw blower-feeders, designed to make every stage of your operations as simple, ergonomic, and efficient as possible. The PRIMOR GII 110.1 Polydrive has been developed with a focus on compact overall height (only 2.67 m with the chute folded), ensuring maximum manoeuvrability with a single feed rotor (powered by the patented POLYDRIVE system, renowned for its high throughput, consistent flow, and versatility for straw, hay, and haylage).
With a load capacity of 11 m3, the PRIMOR GII 110.1 Polydrive can accommodate up to two 2.70 m square bales placed one behind the other and up to four 1.80 m diameter round bales, or three 2.00 m diameter round bales.
Outstanding hay and haylage feeding performance is delivered through its large-diameter all-fodder feed rotor, POLYDRIVE drive, and hydraulic regulating tine bank.
The patented UNROLL SYSTEM holds the round bales inside the body and ensures steady feed from the conveyor to the turbine while limiting the risk of jamming and reducing the need for frequent reverse manoeuvres.
The PRIMOR GII 110.1 Polydrive will be with you for a long time to come, thanks to its oversized components: its reinforced turbine drive casing, which boasts an outstanding rotational speed of 320-620 rpm, K-NOX turbine base, belt fitted with cast-iron sprockets and 14 mm marine-grade chain belt...

The PRIMOR offers maximum loading capacity:

New design, with multiple benefits!

The lowest machine in its class, offering better visibility at work and access to all buildings.

A design focused on the operator!

The PRIMOR GII 110.1 Polydrive is one of the largest straw blower-feeders over 10 m3 in the world, and has been designed to have exclusive dimensions. It’s able to load 2 square bales of 2.70 m with the tailgate closed as well as 4 round bales of 1.80 m: a challenge met thanks to its 5.50 m body length behind the feed rotor. This length also corresponds to the exact width of two loader buckets side by side, making it easy to load silage. Its height of 2.67 m gives operators the best visibility on the market, while still fitting into the lowest buildings.
Its overall length of 7.68 m, which may seem large at first glance, does not compromise manoeuvrability thanks to the specific position of its axle (wheelbase of 5.60 m).

The V-shaped body makes top loading easier (particularly when loading silage). With a body width of 1.40 m at the conveyor and 1.65 m at the top, loading round and square bales from the rear is also made easier, with no risk of snagging.

The optional patented UNROLL SYSTEM ensures optimal use of these large machines when working with multiple round bales. Available on all large KUHN PRIMOR straw blowers, the system uses two hydraulic clamps in the body to hold bales in place. The first bale being distributed unrolls freely, without being constrained by the waiting bales—a situation that often forces operators to move the conveyor forward and backward repeatedly. Once the bale has passed through the feeder, the operator releases the waiting bales to continue feeding or straw blowing. The added advantage of the UNROLL SYSTEM is that it allows the waiting bales in the body to be lifted, making it easy to remove strings or netting without effort.

Intuitive and easy to use!

PRIMOR GII 110 Polydrive is equipped with a host of features to enable operators to work in complete safety and comfort. The machine's electric control panels are compact and intuitive. Functions are clearly identifiable on the console. New operators can quickly and easily learn to use the PRIMOR GII 110.1 Polydrive.

Visual aids on the machine ensure correct settings: conveyor rotation indicator, position indicator for the hydraulic regulating tine bank, tailgate position indicator, etc. At a glance, you'll know your machine is working optimally.
The PRIMOR GII 110.1 Polydrive also has optional cameras: a reversing camera and one offering a view of the separating chamber. The latter allows you to adjust conveyor speed and the regulating tine bank according to how the bale is being distributed.

At every stage of work, this machine has been designed to provide easy operation.

An innovative loading station for improved ergonomics

As standard, the dual tailgate control allows the operator to control conveyor movement, tailgate operation, and the UNROLL SYSTEM from the rear of the machine. Without having to go back and forth to the tractor cab, the operator can perform all bale handling operations.
The new tailgate geometry with its patented bale-holding bar makes daily work easier. This bar closes automatically when a round bale is detected in the tailgate. In the “closed” position, the bar remains within the machine’s dimensions and does not affect overall height.
With a lifting capacity of 1.2 tons, the tailgate can handle even the heaviest haylage bales.
When placed on the ground, the curved shape of the tailgate holds the bale securely—preventing it from falling out the back while strings, netting, or tarpaulin are removed. The bar also features an attachment point for strings and netting, simplifying their removal. Safe access features at the rear of the body allow the operator to work in complete safety. Additional access is provided mid-length along the body with a step and handrail, making it easier to remove bindings from all bales inside.
The body’s sloping rear panels allow operators loading square bales from the rear to open the grab bucket without snagging the rear posts of the machine.

Outstanding performance in its category

The feed rotor system allows continuous adjustment of the flow according to the forage density

A combination of systems for a regular flow

To ensure a consistent output with a minimum number of moving parts, the PRIMOR GII 110.1 Polydrive is equipped with a feed rotor driven by the exclusive POLYDRIVE system. With a diameter of 340 mm, the feed rotor ensures bale unrolling without fodder winding issues, even with long strands. The feed rotor has been designed to minimise maintenance, with scrapers and half-moon openings to prevent fodder buildup around the bearings. Ten discs distributed across the width of the feed rotor are fitted with 60 sections, which cut long strands in combination with the five-tine bank.

The non-hydraulic 7-tine bank as standard can be set during machine startup: either in the low position for operators working mainly with long strands (to facilitate cutting) or in the high position for operators primarily using the machine for straw blowing (to increase access to the turbine and thus reduce straw cutting).
As an option, this regulating tine bank is available in a hydraulic version, allowing farmers seeking versatility (long-stem distribution and straw blowing) to switch configurations with a single press of the electric control. A position indicator on the turbine housing allows the operator to see at a glance the tine bank’s position.
To make handling this highly versatile straw blower-feeder even easier, an intuitive visual guide with setting recommendations is displayed on the turbine. You have all the information needed to adapt the conveyor speed, the regulating tine bank position, and the turbine speed depending on the format and type of forage.

POLYDRIVE drive system: combining power and flexibility

The exclusive POLYDRIVE feed rotor drive system uses a hydraulically disengageable 4-strand belt. Its many advantages include:

A combination of mechanical power (extra force generated by turbine inertia) and hydraulic flexibility for distributing long-strand fodder (haylage, hay).
Smooth operation. Since the feed rotor is independent of the turbine when disengaged, startup requires very little power.
Instant interruption of straw blowing or distribution thanks to the hydraulic disengagement of the feed rotor (ideal for working near posts, drinkers, etc.)
Safety: a conveyor circuit breaker automatically stops the conveyor when the feed rotor is disengaged, removing the risk of jamming during restart.
Quiet operation and low maintenance thanks to belt drive.

The POLYDRIVE disengageable belt drive offers power and flexibility of use

High-speed straw blowing turbine!

The strawblowing turbine on the PRIMOR GII 110.1 Polydrive has been developed for high output. The high-speed 310/620 rpm gearbox delivers 13% more rotation speed than other straw blowers on the market. This ensures straw blowing reaches even the deepest stalls.
The turbine wheel is fitted with 8 wide bolted blades. In case of foreign objects, access is easy. 6 short blades and 2 longer blades create speed differential within the turbine, ensuring more even straw distribution throughout the bedding area. The straw output is drawn into the turbine, avoiding over-cutting of the strands, important for bedding longevity.
To ensure longevity, the turbine base of the PRIMOR GII 110.1 Polydrive is made of K-NOX. This KUHN-exclusive material is highly resistant to forage acidity and wear caused by straw and silica.
The versatile chute, located above and in line with the turbine, ensures the working width of the machine is not compromised. It can be fitted with a manual (or optional hydraulic) outflow pipe that guides the flow of silage for distribution, dropping it by gravity instead of blowing it into the feed troughs—keeping feed corridors clean.
For hard-to-reach bedding areas, the chute can rotate 300°: 18 m to the right, 13 m to the left. Mounted on a circular rack and hydraulically driven, the chute angle is easily adjusted from the electric control panel.
For added precision, the chute cap can also be operated from the control panel, providing greater angular adjustment in tight areas.

Versatile chute: long reach and clean work

A long-term investment

Conveyor guided by cast-iron sprockets on 14 mm marine-grade chain, with or without the BOOST FLOOR option!

Oversized body and conveyor

The PRIMOR GII 110.1 Polydrive is equipped with an oversized, removable conveyor for long-term durability. The 14 mm marine-grade chain is guided at the front and rear by 4 large cast-iron sprockets—eliminating the risk of skewing of the slats or premature wear. Tubular slats bolted to the chains make maintenance easier. The PRIMOR GII 110.1 Polydrive can handle all forage types: straw, hay, haylage and silage.
A galvanized steel double floor prevents forage loss beneath the machine. Accumulated residue can be removed using the cleaning hatch at the rear. Unlike many straw blowers on the market, which recycle long fodder under the conveyor, the PRIMOR GII 110.1 Polydrive’s apron is positioned slightly inside the turbine. The turbine airflow provides a self-cleaning effect for the conveyor.

For frequent silage users, the BOOST FLOOR system is available as an option. This dual-drive conveyor system is activated from the main electrical control:

In straw blowing mode, only one hydraulic motor powers the conveyor, concentrating oil flow to achieve much higher speeds—especially useful at the end of a bale.
In distribution mode, hydraulic flow is split between two motors, giving lower speed but double the torque, ensuring steady forage flow even under heavy loads.

Day-to-day maintenance: a machine designed with farmers in mind!

The maintenance of the PRIMOR GII 110.1 Polydrive has been designed for everyday use:

The drawbar hitch is quick and ensures excellent tractor tracking during tight manoeuvres,
Lubrication is simplified thanks to centralised greasing points. Wherever technically possible, these points have been grouped on the right and left sides of the machine,
The turbine base, the first structural component exposed to wear, is made of K-NOX material, resistant to forage acidity and abrasion caused by silica in straw,
All hydraulic and electrical components are grouped on the same side under a single cover, making them easier to access and clean,
Rear LED lights are embedded in the body uprights: they stay clean longer and are protected from impacts.

Centralised greasing points simplify basic maintenance

For a clean working environment

To maintain a clean work environment, the PRIMOR GII 110.1 Polydrive is fitted as standard with a large projection guard above the feed rotor, guiding forage back into the body instead of onto the turbine.
Two side walls mounted at the top of the front of the body hold large-format round bales at risk of falling sideways to the ground, but also hold the strands in the body at the end of distribution or straw blowing.
The machine’s guards and covers are designed with sloped surfaces to minimise dust and fodder buildup.
For road travel or pasture feeding, optional mudguards are available to keep the exterior clean.

Equipment

Hydraulic outflow pipe recommended for silage distribution

To adjust the distance between the distribution flow and the machine

The outflow pipe guides the flow of silage to the trough. It ensures clean feeding corridors by dropping forage by gravity rather than blowing. As an option, this outflow pipe can be hydraulically adjusted from the tractor cab to drop the forage in the trough.

Manual pump-operated stand for effortless hitching

To facilitate frequent hitching

The manual pump-operated stand makes it easy and effortless to adjust the drawbar height for hitching with the bar supplied with the machine. It replaces the standard telescopic stand, which can only be adjusted by pin and crank.

The winning combination of conveyor speed and power

The BOOST FLOOR system allows the operator to adapt conveyor speed and torque depending on the load in the body. In straw blowing mode, only one of the two conveyor drive motors is engaged, providing accelerated conveyor speed. In haylage and/or silage distribution mode, both motors are engaged, providing higher hydraulic capacity and greater torque. In practice, the conveyor runs smoothly and evenly without jerks.

The exclusive UNROLL SYSTEM makes working with large-scale straw blower-feeders easier.

The only system capable of handling several bales inside the body.

The patented UNROLL SYSTEM consists of two hydraulic clamps positioned inside the machine body. It allows loading of up to three bales inside. The principle: temporarily block waiting bales to allow smooth, pressure-free unrolling of the bale during straw blowing or distribution.
Controlled from both the main and secondary machine controls, the UNROLL SYSTEM also reduces strain on the conveyor and prevents jamming.

The hydraulic regulating tine bank to adapt easily to all applications

For all types of forage and bale sizes

The manually adjustable 7-tine bank is also available in a hydraulic version. From the machine’s main electric control panel, you can continuously adjust the distance between the regulating tine bank and the feed rotor sections in order to apply more or less aggressiveness to the forage. This option can be retrofitted to PRIMOR GII 110.1 Polydrive models that were not originally ordered with this equipment.

60-tooth configuration feed rotor for tough conditions

For distributing long-fibre fodder

The standard feed rotor combines 60 teeth, grouped in two sizes: 103-100 and 80-95. For tough conditions with long fodder strands, cutting is improved thanks to additional cutting power. The “Heavy-duty Kit” equips the entire feed rotor with large 103-100 sections.

For working in tight buildings

Ideal for avoiding interruptions in straw blowing or distribution when a manoeuvre is required in the feeding corridor. The constant speed transmission (or wide-angle) allows you to work when the machine is not in line with the tractor: no risk of transmission breakage!

The adjustable chute cap provides greater precision at the drop point

It ensures accurate product flow for specific situations

Available as an optional feature, the chute cap can be adjusted independently of the chute angle. This additional movement is powered by a hydraulic cylinder. It "breaks" the flow so that the material falls vertically from the chute. Another advantage: straw blowing can be done with an overall machine height starting at just 2.67 m (compared to 2.90 m for standard machines without this option).
The hydraulic chute cap also makes it possible to blow straw with a reduced working height compared to the basic 2.90m machine.
This equipment is recommended for very narrow buildings, for those who need to blow straw behind obstacles (head gates, etc.), or in animal housing with low clearance (gutters, lean-tos, etc.).

Dust control system for cleaner straw bedding CLEANSTRAW

Dust control system for cleaner straw blowing

The CLEANSTRAW system helps to reduce dust circulating in your buildings during straw blowing by spraying fine water droplets. Built into the turbine drive system, water is sprayed by three nozzles in a controlled flow precisely at the right moment. The 64-litre tank, equipped with a suction filter, provides an autonomy of 12 to 18 bales.

Swivel chute for greater versatility during straw blowing

Designed for straw blowing in all building layouts,

the swivel chute can rotate 300°. Mounted on a circular rack, the chute is controlled from the machine's main electrical panel. Straw can be projected up to 18 m to the right and 13 m to the left.
To meet evolving building layouts, the versatile chute is pre-equipped to receive the 300° kit later if needed.
