Long Arm Mowers for Tractors

 

We have truly created a groundbreaking product with our Scorpion arm mower which has been awarded a silver medal in innovation by the Agritechnica Commission. The Scorpion boom mowers are designed for contractors and farmers who maintain large green areas.

 

The Scorpion series has many innovative features that ease the workload of the driver and significantly increase efficiency.

 

GreenTec has more than 30 years of experience in selling machines for landscape maintenance. The machines are developed and manufactured at our headquarters in Kolding, Denmark.

 

An extensive range of hydraulic tools can be attached to the Scorpion arm. We offer attachment tools for trimming trees and hedges, mowing grass in roadsides and slopes, removing moss and weeds from sidewalks, cleaning streams and ditches from sludge and mud, cutting grass under fences and guardrails, etc.

 

The Scorpion arm mowers are available in 3 series which vary in range, minimum vehicle weight, equipment and selection of tools.

 

The Scorpion 8 series consists of 4 different models: 730 S, 730 Plus, 830 S and 830 Plus. All models can either be front or rear mounted.

 

The Scorpion 730 and 830 are available in two versions - Standard and Plus. The difference between the versions is the hydraulic performance and the included equipment. For instance, the Plus models have Rotor Flex and Auto Flex as standard equipment.

 

The Scorpion 8 series contains the largest models of our arm mowers and is particularly useful for work that requires a long reach. Due to their size, the arm mowers must be mounted on a relatively large tractor. It is preferred that the arm mower is mounted in the back of the tractor for extra stability. The minimum required weight of the tractor is 6,000 kg (13,228 lb) for the Scorpion 730 and 8,000 kg (15,432 lb) for the Scorpion 830.

 

No slope or ditch is too long or steep for the Scorpion 8 series as it has horizontal reaches of 7.3 or 8.3 m (23'11" or 27'3"). The boom arms can also be used in forest areas for cutting branches off tall trees by using the large vertical reaches of 9.5 or 10.5 m (31'2" or 34'5") depending on model.

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 (Patent Pending)

 

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 (Patent Pending)

 

All Scorpions comes with a brand-new and patent pending 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 puchased as optional equipment for the S models.
 

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
