ActiveMow

• Fully welded: Robust, sealed and permanently lubricated
• Long-lasting satellite drive with massive spur gears: quiet running and top efficiency
• No inner shoe for trouble-free cutting

The enclosed and fully welded cutterbar meets the highest quality standards and operates dependably and leak-free over many years of hard work. Massive and oil-immersed spur gears impress by very quiet and reliable running in sustained peak-load operation.

The cutterbar is driven by the right-angle gearbox just behind the inner top hat – for blockage-free operation on headlands and in awkward patches.

The established satellite drives were developed by KRONE and have proven extremely well all over the world for as many as 30 years now.Its massive spur gears with up to 59 teeth transmit the drive power down to the very last disc. The large-diameter gears rotate at reduced speeds, with a higher number of teeth meshing with the neighbouring gearwheels for even quieter running, ultimate efficiency and maximum longevity. The auxiliary gears drive one disc each and as a result are exposed to only minimum loading.

Using welding robots and CNC technology, KRONE manufactures its cutterbars to the highest quality standards, ensuring they are fully welded and permanently lubricated. After all, the cutterbar is the heart of every disc mower.

The completely welded cutterbar is maintenance free and won’t leak nor lose shape even in so many years of work. We give it special cleanings throughout the manufacturing process so we can implement permanent lubrication and eliminate the need for oil changes.

• SmartCut for stripeless cuts
• The wedge-shaped cutterbar guarantees clean cuts
• Heavy-duty spur gears run in widely-spaced double bearings
• Swathing or spreading

The wedge-shaped cutterbar offers many different setting options that allow you to make short cuts in meadows and pastures and higher cuts in long-stemmed forage crops. An ActiveMow mower delivers a reliable performance and clean cut.

Large-diameter spur gears with truncated teeth offer greater efficiency as a larger number of teeth is in mesh at any one time.

With some discs turning in pairs towards each other and others turning away from each other, it was necessary to redesign the degree of blade overlap to ensure cleanest cuts. For stripeless cuts in light and young crops, we have therefore increased blade overlaps on the discs turning outwards. In addition, the blades turning to the rear are set further apart to encourage a smooth flow of large volumes of crop.

The wedge-shaped cutterbar offers many height setting options. The spur gears run in massive double bearings, allowing the cutterbar to handle extremely high loads.

The spur gears are arranged in a forward position and eccentrically inside the gearbox right under the discs. The small auxiliary spur gears are removed from above, the massive main gears gearbox from the side.

We welded curved stops between the individual skids that protect the cutterbar from damage and also contoured the underside of the stops in such a way that no material can build up here and instead flows smoothly to the rear.

The eccentric bearings are positioned in such a way that the discs feed the material to the middle of the machine for the tractor to straddle it. With discs spinning in the A sense of rotation, ActiveMow R 200, R 240, R 280 and R 320 form one single swath whereas the ActiveMow R 360 forms two swaths with its discs also spinning in the A sense of rotation.

Swathing is the preferred option in wet and boggy terrain so the tractor wheels will not run on the crop for loss-free pick-up or tedding.

With discs spinning in the B sense of rotation, ActiveMow spreads the material across the full cutting width. Here the discs turn in pairs towards each other.

Spreading the material across the full machine width instead of swathing, it exposes a larger surface to the sun and wind for boosted and more uniform wilting.

• Fast blade changes for high productivity
• Replaceable pins and wear parts
• Wide skids protecting the cutterbar

There are many reasons for choosing an ActiveMow disc mower. Just think of the quickchange blades, the inexpensive wear parts and the perfect disc arrangement for stripeless cuts.

Quick-change blades are considered a must by many farmers and contractors. The blades are quick and easy to reverse or replace in situ.

The curtain folds up for cleaning and replacing the blades – a compact design that offers superb accessibility.

Spare blades are neatly stored in this mobile drawer.

The wide skids are fabricated from hardened boron steel to minimise the ground pressure and give enhanced contour following and cutterbar protection. The skids are bolted to the cutterbar so they are easy to replace.

Blades of 118 mm length orbit with a generous overlap, producing the typically clean cuts and feeding the material to the rear in a consistent flow.

Worn blade fixing pins and wear parts are not an issue for KRONE Active- Mow, because the modular design of the discs allows you to replace them individually. If you like, you can opt for bolts instead of pins.

• Full driveline protection
• Neighbouring discs will not collide
• Wear-free
• Quick-change roll pins for minimum costs

You know it too well – foreign objects can cause great damage and costly repairs.
KRONE SafeCut offers a maximum of protection and peace of mind. The system which comes
as standard specification offers a unique level of disc protection and functionality.

Orbiting within the sphere of the mower bed and never protruding beyond the skids, the discs benefit from two-fold protection. Besides, additional protection comes from the standard SafeCut system.

There is no load on the roll pins during operation. The bearing is tensioned by a nut and two clamping screws. As a result, the roll pins do not suffer from material fatigue and will break only at their inbuilt load level - even after many hours of use.

Each disc on the mower has its own individual impact protection. When the blade hits an obstacle the shockload is transferred to a roll pin which breaks. As a result, the disc automatically threads 15 mm up on the drive shaft.

If the system is suddenly overloaded, the impact is not directed to the spur gears in the driveline, instead a roll pin in the sprocket drive shaft shears off. The pinion shaft continues spinning, jacking up the disc in question, moving it out of the risk zone and the orbit of the neighbouring discs. As a result, SafeCut prevents damage to the spur gears and the neighbouring discs. The roll pins can be replaced in just a few minutes and cost next to nothing.

• Tractor attachment with three-point headstock
• Large travel range for superior performance in mountainous terrain
• Direct and frictional driveline ensures no power is lost
• Working a full width by refitting pin on the link arms

The side-mounted linkage is compact, low in weight and gives the mower large up/down travel. The ActiveMow mowers follow any ground contours and have proven absolutely well in mountain applications.

The break-back system relies on an adjustable coil spring, which responds instantly and dependably and allows the mower to swing back and up when impacting a foreign object.

Offering a large up/down travel range, the ActiveMow disc mowers are perfect for work on slopes and in undulating and rough terrain.

Offering a large up/down travel range, the ActiveMow disc mowers are perfect for work on slopes and in undulating and rough terrain.

The sturdy three-point headstock features a bracket to store the driveshaft after the machine is removed from the tractor.

You can side-shift the machine by refitting the pins on the link arms. This way you get the full cutting width despite different wheelbases when working on slopes and in combination with a front mower.

Drive power flows through a frictional driveline of pto shafts and gears for maximum effciency even in diffcult conditions.

The oil lines are tidily stored in a holder when the machine is not in use. The hose couplers have handles for easy attachment and removal.

The pin secures cat I and II top links and is locked to stop it turning.

• Coil springs provide the cutterbar suspension, optimise the ground pressure and ensure uniform cuts
• The springs are conveniently adjusted by resetting pins
• Extremely responsive for top contouring

Manually adjusted, the ActiveMow suspension springs rapidly adapt the ground pressure for the machine to produce perfect cuts in undulating terrain and at high work rates and as a result of this clean and high-quality forage as well as a fast and uniform re-growth.

The ground pressure of the cutterbar is controlled by adjusting the tension of the coil springs. The ActiveMow R 240, R 280, R 320 and R 360 models have pins that reset the spring tension without the use of tools. The ground pressure drops as the spring tension increases.

The low-deadweight ActiveMow R 200 has only one coil spring that provides infinitely variable adjustment.

The ActiveMow R 240 has two coil springs that are adjusted without tools. The inboard spring is adjusted on a spindle, the outboard spring by refitting a pin.

ActiveMow R 280, R 320 and R 360 have three adjustable coil springs – one that adjusts the inboard arm and two that control the outboard arm.

For convenient attachment/removal of the machine, release the spring tension simply by operating the latch on each spring. Such latches are specified on the ActiveMow R 240, R 280, R 320 and R 360 models where they eliminate the need for unhooking the coils.

• 100° transport position for safe travel on public roads and clear view behind
• Compact configuration for fast travel
• Stored on stands and in vertical position for minimum storage space
• Lower links are not raised during the headland turn

KRONE disc mowers offer a wide range of practical solutions that make your work easier andmore efficient. These include the 100° transport position for a uniform weight distribution and excellent visibility during transport and the optional vertical position for storage.

On the headland, the mower is raised hydraulically to enable convenient turns and avoid running on cut material. The link arms are not raised. A stop limits the lift range.

Stands are available as an option to store the machine either in work or transport position and save space in the machine shed during winter storage. The side guard folds automatically when ActiveMow moves into transport or park position, thereby reducing the machine’s height.

To get ready for transport, ActiveMow folds into a 100° angle position behind the tractor. Taking weight off the right wheel, it increases the road stability of the combination. The operator enjoys an unobstructed rear view in the mirror.

It takes as little as one single-acting coupler to move the ActiveMow into work or transport position. The tap that controls the parking position is in easy reach right next to the hydraulic cylinder.

Unlike a mower that swings horizontally behind the tractor, ActiveMow swings up, thereby taking less load off the front axle and increasing stability during fast road travel and work in rough fields.

High-cutting skids are the solution for those who want 80mm and longer stubble. Depending on how you bolt the skids to the cutterbar, you can increase the cutting height by 30 mm or 50 mm.

These deflectors are fitted to create narrower swaths. They avoid tractor wheels running on the cut material and are ideal in boggy terrain.
