Technical highlights

α-motion

Hitch-On – The 3 Click Strategy

1. Connect the mowing unit to the Weiste triangle and fix on the retaining chains.
2. Plug in the drive shaft.
3. Connect up basic shaft hydraulics.

Rapid-Reaction Spring-activated floating
Two large springs are built into the hitch-on rack.
They provide even suspension of the mowing unit over a large
working area and in all working conditions.
Springs stabilise the mower when turning on the headlands.

Lifting A simply acting cylinder is enough.

The “active” support frame

Every movement of the mowing unit controls the frame and activates the “floating cut”. If the terrain falls, the frame lowers, if the terrain rises, the frame lifts. Unrivalled protection of turf by perfect guidance over every ground contour – even at high speed and on wet ground. The mowing unit is protected from sharp impacts.

Additional lifting height

Through the “active” support frame – the ground clearance is also increased.

Hitch-on rack
Alpha-motion, the recently developed front technology, heralds a new age of disc and drum mowers. The mower can be hitched to any tractor of between 60 and 300 hp – regardless of model and size. The various different front linkages have no effect on the suspension and ground tracking of the front mower unit.
It takes just a few minutes to hitch up.

Circle of α-motion

The advantages of Alpha motion:

Mower can float by +/- 9.84” / 250 mm, or 19.69” / 500 mm in total, above or below the tractors front wheel level.
Angle of inclination of cutter-bar self-adjusts by +12°upwards, -9° downwards, so significantly less risk of soil damage and reduces wear.
Higher speeds can be reached – without having to remove the mowing unit.
Optimum protection of turf and machine.
Clearance of 13.78” / 350 mm on headland turns and transport setting.
Outstanding design provides perfect view of the mowing area.
Mower unit moves almost vertically, small slide paths on the drive shaft and significantly lower dynamic loads.

EUROCAT drum-type mowers

The newly-developed drums on the EUROCAT drum-type mowers deliver high-quality work in all conditions.

The ultimate design of drum body tackles the densest of crops without problem.
Not affected by dirt.
Swath can be placed using swath formers.
Changing from conditioner with wide-spread to swath formers takes just minutes.

Best crop flow

Low-slung design - trouble-free transfer from mower disc to conditioner.
Inner drum bodies are smaller diameter for improved clearance.
Heavy-duty inside body with large bearings.
Outer mower drum is bolted to gear trough for straightforward removal.

The big plus ...

EUROCAT with infinitely-variable cutting height adjustment system

The height of all 4 drums can be adjusted simultaneously from above.
The heavy-duty adjustment system is fully sealed in a metal housing encapsulated by a rubber boot.

Benefits:

Smooth working and always easy to adjust.
Easy access.
Cutting height adjustable from 35 to 60 mm.
High-cut saucers optional (20 mm extra cutting height).

Exemplary

Drum mounting bolted to gear trough - easy access from outside.

Central cutting height adjustment system on EUROCAT plus
All 4 drums adjusted simultaneously from above.

Detailed information

EUROCAT classic - Front mounted mowers

Shortened headstock

The shortened headstock places the mower closer to the tractor
The gearbox is now lower down to reduce the angle of the PTO shaft
The headstock is the key component for perfect ground hugging. The 3-point suspension system mounted on ball joints gives the mower multidimensional freedom of movement
Adjustable stabiliser springs are integrated into the headstock to keep the mower centred when raised during transport

Drive system

Power is transmitted from the PTO shaft through the incoming gear unit to drive connecting shafts and the hexagonal shaft that drives the mower drums
The hexagonal shaft runs submerged in oil to provide reliable drive to the mower drums
The driveline is protected by an overload clutch in the PTO shaft
A freewheel is integrated into the driveline

Weight alleviation provided by two powerful springs

Two powerful springs ensure a uniform ground pressure over the whole width of the cutter bar
The pressure the cutter bar exerts on the ground can be adjusted quickly and easily by adjusting the length of the chain

Guards

The guards can easily be raised and locked in position
The side guards can also be raised hydraulically if required, to increase operating comfort

EUROCAT alpha-motion - Front mounted mowers

alpha-motion headstock for front mowers - (R)evolution in mower technology

„Active“ carrier frame - a worldwide first. It responds immediately to every ground contour
Linkages and carrier frame react to every bump in the ground. The mower unit rises to float over each bump and is guided down into each dip. The result: unique ground hugging to protect the sward and the machine
Unique freedom of transverse movement +/- 16° due to ball joints on link arms
Rapid-response weight alleviation springs: vertical travel of +/- 250 mm (500 mm total) with constant weight alleviation
Optimised centre of gravity close to tractor
Fits any tractor between 60 and 360 hp
Perfect view of work area thanks to unique design
Higher travelling speeds possible - without the mower unit bouncing

Drive system

Power is transmitted from the PTO shaft through the incoming gear unit to drive connecting shafts and the hexagonal shaft that drives the mower drums
The hexagonal shaft runs submerged in oil to provide reliable drive to the mower drums
The driveline is protected by an overload clutch in the PTO shaft
A freewheel is integrated into the driveline

Weight alleviation provided by two large-dimensioned springs

Two powerful springs are integrated in the headstock
The springs ensure that the mower is evenly counterbalanced with 500 mm of vertical travel

Guards

The guards can easily be raised and locked in position
The side guards can also be raised hydraulically if required, to increase operating comfort
