Page 21: Introduction
INTRODUCTION The Twose range of Boom Flail Trimmers has been designed with both the farmer and the contractor in mind - which has resulted in a boom flail with a very high specification - with many features not found on other machines. - Page 22 The cutter head design is of a ‘double skin’ construction for greater strength and longer life. The drive is by means of ‘vee’ belts from the hydraulic motor to the rotor, with the drive completely contained within the width of head for a cleaner cut. Twin ‘vee’...

Page 23: Tractor Selection
TRACTOR SELECTION Tractor Specifications TE480 – Tractor size must be a minimum of 45kW (60 HP) – 3000kg Tractors must be equipped with a power take off (PTO) shaft that must run at 450 rpm during operation. The PTO shaft should run clockwise when viewed from the rear of the tractor and ideally be of a 1⅜”... -

Page 32: Operation Information
FLAIL TRIMMER- OPERATION INFORMATION The vehicle driver should be conversant with all tractor controls and capabilities. It is always advisable for the tractor driver to practice the controls and operations of the Flail Trimmer, in a safe open location away from potential hazards, prior to setting off into work. -
Page 33: Rotor Control
DANGER VERY IMPORTANT It is very important that motor spool and motor spool control lever works in one direction only - From centre (OFF) position to selected (ON) 'rotor cut' direction position – permitting the rotor one direction of cut and the 'OFF' setting only. This eliminates the chance of going from ‘cut-up’... -

Page 36: Hydraulic Controls - Cutting Position
HYDRAULIC CONTROLS - CUTTING POSITION The cutting head must at all times be lowered gently into the cutting position. Never ‘drop’ a flailhead into a hedge at speed. When cutting at ground level (grass etc.) the head must be lowered gently to give a slight contact pressure of roller to ground. -
Page 37: Transportation
TRANSPORTATION For transport the machine should be ‘folded’ into a position that is as compact as possible within the confines of the tractor width. The cutting head should be placed into the vertical position with the flails outwards ensuring sufficient clearance of the tractor wheel to avoid possible contact or fouling during transportation. -
Page 38: Cutting Head Belt Adjustment
CUTTING HEAD ‘VEE’ BELT ADJUSTMENT To adjust the cutting head ‘vee’ belts the following procedure should be followed: - Position the cutting head on the ground in a safe level location with the drive end uppermost. Switch off the tractor engine, remove and pocket the key. ... -
Page 39: Cutting Head Belt Replacement
CUTTING HEAD ‘VEE’ BELT REPLACEMENT To replace the cutting head ‘vee’ belts the following procedure should be followed: - Hydraulically position cutting head to stand vertically on the ground with the drive end uppermost - this should be done on a firm and level location to ensure the cutting head is steady and safe in this position. -
Page 40: Rotor Removal & Replacement
ROTOR REMOVAL & REPLACEMENT Removal procedure: With the machine attached to the tractor, hydraulically position the cutting head vertically with the drive end downwards resting on the ground – select a firm level location and ensure the weight of the head is fully rested on the ground. ... -
Page 41: Roller Height Adjustment
ROLLER HEIGHT ADJUSTMENT The cutting height of the flail head may be adjusted to cut at 4 different heights; this is achieved by altering the mounting position of the roller on the flail head - refer to diagram below. To alter the roller position, each end bracket of the roller and the relative securing bolts will need to be positioned at either of the four position height options offered. -
Page 42: Machine Removal
REMOVING THE MACHINE FROM THE TRACTOR Select a good clear, level and firm site on which to detach and store the machine. IMPORTANT Use the hydraulics to lower the head onto the ground horizontally (as if you were cutting grass). ... -
Page 43: General Maintenance
GENERAL MAINTENANCE General Lubrication example illustration opposite indicates the general locations of lubrication points - all points should be greased on a daily basis and prior storage of the machine. New machines must be greased prior to first use. Gearbox Lubrication Check gearbox oil level on new machines prior to first use, top up if required before using the machine. - Page 44 SERVICE SCHEDULE Every Day Grease machine fully prior to work (and prior to storage). NOTE: New machines must be greased before initial use. Check for broken or damaged flails. Check tightness of flail nuts and bolts. Visually check for oil leaks and damaged hoses. ...
- Page 45 HYDRAULIC SYSTEM Oil Supply Check the oil level in the reservoir daily. Oil Condition & Replacement No fixed time period can be quoted for oil changes as operating conditions can vary widely but a visually inspection of the oil will often indicate its current overall state. Signs of a reduction in its condition will be apparent by changes in colour and appearance when compared to new oil.
- Page 46 Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections. All Hydraulic Hoses (BSP) fitted to Twose Hedgecutters have ‘soft seal’ connections on both flail and ram circuit hoses.
- Page 47 CONTROL CABLES The control cables operate on a push/pull system with the spool centring springs always returning the spool to the neutral position when the handle is released. Care should be taken during installation and operation to ensure that the cables are not trapped or kinked.
- Page 48 PTO SHAFT MAINTENANCE PTO Shaft Lubrication The PTO shaft should be lubricated on a regular basis using lithium based grease – each end of the shaft has 2 greasing points; one for lubrication of the universal joint and one for lubricating the rotating fixing ring of the shaft shield –...
- Page 49 TORQUE SETTINGS FOR FASTENERS The chart below lists the correct tightening torque for fasteners. This chart should be referred to when tightening or replacing bolts in order to determine the grade of bolt and the correct torque unless specific torque values are assigned in the text of the manual. Recommended torque is quoted in Foot-Pounds and Newton-Metres within this manual.
