Boom Mowers for Small Tractors
GreenTec's Scorpion range of boom mowers is based on more than 30 years of experience in the industry. The Scorpion series has many innovative solutions that increase the capacity and relieve the user. The machines are manufactured in a functional and simple design. It creates favorable conditions for both the environment and the bottom line.
In 2019, the Scorpion series was awarded a silver medal in innovation by the Agritechnica commission. It is one of the highest accolades for machinery in green area maintenance.
The Scorpion series is used in all seasons of the year as we provide a huge selection of hydraulic attachment tools for grass mowing, hedge cutting and hedgerow maintenance.
The Scorpion range consists of 3 series of boom mowers that vary in reach, required weight of the vehicle, equipment and available tools.
The Scorpion 330 & 430 are intended for small tractors, implement carrier, skid steer loaders and the like. The reach mowers are used for roadside maintenance by contractors and hedgerow maintenance by farmers who want to achieve high capacity and efficiency. All you need is a minimum vehicle weight between 1,500 and 2,200 kg (3,300 and 4,850 lb) depending on the model.
The Scorpion 4 series is build in a modular system and available in different versions.
PTO driven versions:
- Rear mounted in three-point suspension, category 1 and 2, 350-540 RPM
- Front mounted in three-point suspension, category 1 and 2, 600-1000 RPM
- Reverse mounted in three-point suspension, category 1 and 2, 350-540 RPM
Basic versions (Oil supplied from loader, implement carrier or tractor):
- Front mounted with loader brackets
- Front mounted with special brackets
- Front mounted in the three-point suspension
The small size of the boom mowers makes them suitable for areas with limited space, such as verge mowing on sidewalks and bike paths or hedge trimming in residential areas or gardens. The arm can be folded for transport position reducing the width to 1.8 m (5'11") for the Scorpion 330 or 2.2 m (7'3") for the Scorpion 430. The compact design of the boom mowers ensures a low transportation height of 1.22 m (4'). It gives the driver a perfect view to the arm and cutting head, especially if the boom mower is front mounted.
The 155º hydraulic turn of the arm provides many opportunities for the driver, such as free movement of the attachment tool to cut in front, behind or even beneath the vehicle. You can also reach across hedges to trim the branches on the other side.
The micro boom mowers are available in 3.3 or 4.3 m (10'10" and 14'1") working widths so you easily can mow grass in verges and small hills. The vertical working widths consist of 3.1 or 4.1 m (10'2" or 13'5") whereby the arm can be used for maintaining hedgerows.

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 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)
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
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 be purchased 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.
