Tractor Mounted Boom Mowers


Our Scorpion boom mowers have many innovative features that provide environmentally and economically benefits for the user while increasing the driving experience and road safeness.


A large selection of tools can be attached to the Scorpion boom mowers for roadside maintenance and hedge trimming. The wide range of attachment tools makes the Scorpion a popular choice throughout the entire year.


The Scorpion reach mowers are divided into 3 series which vary in reach, minimum vehicle size, equipment and available attachment tools.


The Scorpion 6-series consists of 4 different models: 530 S, 530 PLUS, 630 S and 630 PLUS. All models are rear mounted.


The Scorpion reach mowers are available in two variants, STANDARD and PLUS. The difference between them is mainly the hydraulic performance and the included equipment. For instance, the PLUS models have Rotor Flex and Auto Flex as standard equipment.


The boom mowers have horizontal reaches of 5.3 and 6.3 m (17'5" and 20'8"). It enables you to mow grass and shrubs on steep slopes by attaching a flail mower to the arm. You can also mount hedge trimmers and limb saws on the boom arm and reach high branches by extending the arm up to 5.1 or 6.1 m (16'9" or 20'). 


The Scorpion 6-series is designed for medium-sized tractors with a weight of at least 4000 kg (8,818 lb). 


The patented 4-point mounting system connects the tractor and the boom mower and gives 100% stability. It is also easy to mount. The Hybrid Arm System provides great flexibility and increases the work capacity and environment. The Danfoss hydraulic system on the 6 PLUS models ensures reliability and high output. Furthermore, the joystick is easy to operate.

The World’s Strongest Manufacturing Steel - Strenx 700

Strenx Steel is a collective name for all the high strength steel brands supplied by the Swedish Steel Group SSAB. It includes Optim, Weldox and Domex to name a few.

In June 2019, GreenTec became a certified user of Strenx Steel. It has cleared the way for more opportunities to manufacture new and competitive products in a lighter, stronger and environmentally friendly design.

All Scorpion boom mowers are manufactured in Strenx 700 steel and it optimizes the weight and strength ratio significantly.



Hybrid Arm System (Patented)


The Scorpion series has a Hybrid Arm System

The Scorpion models have an innovative arm control concept which provides new opportunities and advantages.

The brief explanation is that the Scorpion models can be controlled with or without parallel motion and you will achieve the best of both worlds on the same machine. The parallel motion takes place through a Master Slave System and is especially used for hedge trimming. The non-parallel motion shines in cramped conditions, such as forest roads and trails. It can also be particularly useful for grass mowing in slopes and ditches.

There is no need to acquire a telescopic extension for the arm due to the great flexibility of the Hybrid Arm System. The two outer arms on the reach mower are remarkably compact. With the use of the short inner arm, you can achieve the flexibility that a regular telescopic extension would give. It simplifies the construction of the machine and reduces the overall weight.

It is easy to disable or enable the use of the parallel motion through the control panel. The functionalities of the arm are controlled through a joystick.


Benefits from the Hybrid Arm System:


  • Increased flexibility
  • Greater capacity
  • Reduced weight
  • Satisfied customers



4-Point Mounting System (Patented)


Patented 4-point mounting system for Scorpion boom mowers


All Scorpions come with a patented 4-point mounting system.

Instead of the traditional three-point mounting, the Scorpion models have four mounting points on the mainframe.

The two lower points are connected to the tractor’s lift arms while the two upper points are attached to a triangular frame in the tractor’s top link bracket or a K80 ball hitch.

If the boom mower has a horizontal reach larger than 7 m (23’), the boom mower is stabilized with additional connections from the machine to the tractor’s drawbar or K80 ball hitch.

The 4-point mounting system is an incredibly easy solution and provides 100% stability between the boom mower and the tractor.



Forward reach with Rotor Flex


Forward reach with Rotor Flex


As a standard, the arm on the Scorpion models can be turned 155 degrees (55° forward and 100° back).


Rotor Flex is included on all Scorpion PLUS models and can puchased as optional equipment for the S models (except Scorpion 4 S).


With Rotor Flex, you can turn the cutting head up to 270° and adjust the cutting angle up to 180°.


Rotor Flex has a double pivot joint which enables you to move the cutting head forward, so it is in the driver’s natural field of vision.


The cutting head can also be moved behind the vehicle which is useful for verge mowing on small roads with oncoming traffic.


Rotor Flex automatically positions the vertical pivot joint correctly. It relieves the stress on the driver and is applied for hedgerow maintenance as the saw or cutter bar automatically is adjusted to cut vertically.



Auto Height Control (AHC) for Verge Mowing

The AHC is available as optional equipment for the Scorpion 6 and 8 series. It has been developed in close cooperation with Danfoss, the leading hydraulic specialist.

AHC is used for verge and ditch mowing. It ensures that the cutting head floats above the surface and does not mow into the ground by following the contours of the terrain. This is all done automatically. The driver does not need to maneuver the boom mower with the joystick.

AHC can be enabled from the cabin and the driver can concentrate on the traffic and potential obstacles in the way.

The fact that the cutting head floats above the ground contributes to far less stress on the device which results in fewer maintenance costs.

Benefits from the Auto Height Control:


  • Work relief for the driver
  • Increased road safety
  • Lower maintenance costs
  • Increased capacity
