The Spider is a remote controlled self-propelled mower for the maintenance of steeply sloping areas such as embankments, roadsides and hillsides; areas that are otherwise typically maintained by teams of brush-cutter operators or tractor-powered reach mowers. Although referred to as a mower, “it performs more like a remote-control slasher”, is a regular comment from those attending demonstrations. It capable of cutting waist-high growth, thick and wet kikuyu, weeds and small shrubs and plants. The Spider Mower cuts slopes up to 40 degrees with its 4 wheel drive lugged tyres, and up to 55 degree slopes with its optional winch system.

FEATURES OF THE SPIDER ILD01 SLOPE MOWER

POWER UNIT

• Kawasaki FS 541V Vertical crankshaft V-twin air-cooled 4 stroke 2 cylinder engine, producing 18 hp at 3600 rpm
• The engine runs on standard unleaded or premium 95 octane unleaded for maximum performance
• Alloy construction fits into the overall Spider design philosophy of light weight package for optimal power to weight ratio
• Electronic spark ignition for reliable starting and performance
• Pressurised lubrication system for long life on slope conditions

• Dual element air cleaner and dual barrel carburetor with fuel shut-off solenoid
• Rotating grass screen to assist effective engine air-cooling
• Cast iron cylinder liners
• Separate choke and throttle controls for easier starting
• Electric starter with a 12 volt on-board battery and electrical system
• 12 litre fuel tank capacity providing between 3 & 5 operating hours depending on slope and conditions

CUTTING DECK

• The deck body and super structure is made from aluminium alloy to obtain minimum overall weight of 245 kg
• The vertical engine crankshaft is coupled to an electric clutch for engagement/disengagement of the belt driven cutting blade
• The clutch unit incorporates a brake device to stop blade rotation on disengagement

• Cutting is done by a single mulching blade 780mm long (31 inches)
• Overall cutting width is 850mm (34 inches)
• The mulching blade is set well within the deck body to minimise the ejection of grass and debris during mowing. The blade is thick hard blade steel.

• Mowing deck height is electrically adjustable from 90 to 140mm
• The height setting is controlled from the operators remote control and is variable during cutting

DRIVE AND STEERING

• A hydrostatic Sauer Danfoss drive system provides continuously variable travel speed in two speed ranges (turtle and rabbit modes) from 0 to 7 km/h, in forward and reverse
• All 4 wheels are driven by the hydraulic motors. All speed, steering and direction controls are located on the operator's wireless remote control
• Steering is 360 degrees on all 4 wheels without lock-to-lock limits
• Tyres are lugged 16x6.5x8 tube tyres

• The Spider Mower is capable of cutting on slopes up to 40 degrees under its own wheel drive
• Beyond these angles, the optional winch system must be utilised to ensure machine stability and safety

• The normal steering mode is referred to as the "dancing" step and is the mode normally used for mowing. In this mode all 4 wheels turn at the same time

REMOTE CONTROL SYSTEM

• Other than the clearing of an Emergency-Stop and engagement of winch operation; all operator controls are performed through the wireless remote control station

• The controller comes with a belt strap and is normally strapped to the operator as two-hand operation is required
• If the controller is dropped or all hands released, the controls revert to the neutral position and the Spider mower stops driving
• Controls include: engine start, stop and rpm; E-stop, forward/reverse speed control, steering controls, deck engagement/disengagement, height control

ACCESSORIES

• A roll of the key tools required to undertake the daily checks and maintence tasks is strapped to the mower

OPTIONS

• The winch is hydraulically powered and integrated with the drive system
• At extreme angles, the winch system provides machine stability, traction and prevents rollover
• The integrated winch control is automatically synchronised with the drive wheel control, and does not require any additional operator controls
• The winch also maintains the engine orientation to ensure engine lubrication

• Extraordinary as it is, this is a 55 degree slope
• Such slopes would ordinarily be considered beyond the normal practical limit of a maintainable slope
• But the Spider Mower with integrated winch system is capable of cutting such slopes

• A typical illustration of the hydraulic winch system in operation
• In this example the winch rope is anchored to a road-side guard rail
