Overview

The Orbital will significantly increase output when mowing long runs due to its ability to work on either side of the tractor by swinging through 180 degrees. This feature eliminates non-productive travel and reduces tracking on embankments. The optional hydraulic carriage attachment reduces the gross vehicle weight of the tractor. A minimum of 120hp for 606 to a maximum 200hp for the 836.

● Autopilot automatic arm control system
● High output 80 hp piston power drive system
● Oil cooler for continuous high output
● Sensitive hydraulic proportional controls
● Parallel arm geometry for ease of use
● Quick attach axle mounting system

Features

       
Autopilot
Claimed to be the biggest advance in on-ground mowing since the flail mower! Automatically adjusts the height and angle of the cutting head to maintain the required setting, freeing the operator to drive safely at up to twice the normal.he simple and reliable award winning Autopilot system enables the flailhead to follow the ground contours accurately both up and down.
Custom flailhead
The Orbital flailhead is designed specifically for high output. The in-board motor and belt drive system minimises the "dead length" from the outside of the head to the first flail and facilitates cutting close to obstructions.
Ease of maintenance
The needs of the service engineer have been given priority at the Orbital desgin stage. The telescopic arm slides on special nylon wear pads with simple external screw adjustment for timly and easy adjustment.
Oil cooler
A themostatically controlled full flow oil cooler ensures the hydraulic fluid remains at it's most efficent temperature.
 
       
Piston power
High capacity mowing is made easy with the Spearhead 84hp piston pump and motor drive system. Automatic pressure modulation in the drive circuit eliminates pressure peaks on start up and shut down, increasing the life of the hydralic system.
High speed transort
High- speed transport is a key requirement with the Orbital range. Hydraulic slew puts the reach arm directly behind the tractor within the 2.6m transport width.
Hydraulic under carriage
The optional hydraulic under carriage reduces the weight of the tractor/ mower combination by 2.5 tons to bring 100bhp tractors within the manufactures gross vehicle weight limit.
   
       
 
 
Control Options

       
Proportional Controls
The Spearhead low pressure over high pressure hydraulic control system is widely used in the construction industry where precise proportional control and complete reliability are essential.

Ergonomically arranged with logical directional movements make the Spearhead controls the operators favourite.
 
Attachments

       
Flailhead
Spearhead flailheads are available in cutting widths of 1.2m or 1.5m with a choice of flails to suit all conditions. Please note that the 1.5m flailhead isn’t available on some models.
Sawhead
Available in variable sizes dependant on diameter and number of blades required. 600mm and 700mm diameter blades available with 4 blades dependant on width of cut required and size of Power Arm used.
Cutterbar
A standard cutterbar available in 1.2m and 1.5m cutting lengths. A cutting capacity of up to 20mm.
Ditch and grip cleaner
With a 600mm diameter and fitted with 3 cutting blades and 3 throwing blades the Spearhead ditch and grip cleaner is perfect for clearing any ditch.
