NetWizz Hi-Lift Mast Auto Tension

"NetWizz High Lift Auto Tension" is a machine for applying and removing bird netting in medium to large vineyards, orchards and anywhere crop cover is required. Netting is wound onto a simple spindle in an inter-woven pattern like a roll of twine.

This model is ideal for applying netting over fruit trees (pictured covering single row Tatura trellis, with mast offset 30º) and applying wide netting in vineyards. This mast incorporates a lot of the same features as the standard mast:

Key Benefits
  • Automatic speed and netting tension Fast, safe removal of netting without tears
  • Netting wound tight on steel spindles
  • For single and multiple row or full canopy cover netting.
  • Self loading and unloading of netting rolls
  • Very compact & safe design
  • Shear bolt protection which prevents damage to the arms or mast if hit by an object. 
  • Mast assembly rotates a full 360º and can be pinned at 90º and 15º intervals.
  • Main mast is raised and lowered with hyd ram.
  • Mast extension has three length settings and is quick, simple and safe to alter.
  • bottom mast eye is adjustable in length and has 3 rollers on for easy net applying.
  • When retrieving netting the mast is rotated to the front over the tractor making it a lot easer to remove netting.
  • Each arm is telescopic, adjustable in length and easily folded up then pinned against the mast for transport.
  • Mast can be easily fitted to any existing NetWizz Std Auto Tension.

Fast, safe removal of netting without tears

If netting gets caught the sensor automatically stops the spindle, preventing tears. The sensor automatically adjusts the spindle and wand speed to maintain a constant incoming net tension.

This unique sensor system (with rollers) greatly prolongs the life of netting.

Netting tension remains constant, no matter what size roll is being wound up or the tractor's ground speed.

 

Shear bolt protection for top arms & mast

The NetWizz mast incorporates a heavy duty shear bolt assembly which breaks a small bolt, preventing the top loop and mast from damage. This arrangement is now a lot heavier than before, Ø24 pin in 10mm plate

To work around power poles, trees and for transport, a spring loaded rotating pin is disconnected allowing the mast assembly to rotate.
All model masts can rotate a full 360º and can be auto-pinned at 15º intervals.

 

Self loading and unloading of netting rolls

Full spindles are loaded using the tractor’s 3PL. The tractor is simply reversed into the roll, with the aid of self-locating guides, then raised with the linkage. If required, an extra roll of netting can be carried on the two arms which slide out.

In its standard narrow setting (shown above), the larger roll is 15m wide x 300m long, the smaller being 10m wide x 100m long both on 1.1m long spindles.

The steel spindles protrude from the end of the roll enabling easy safe mechanical handling.

The new NetWizz models are easy to adjust in width from:
1.15m outside wide for long distance transport
1.1m spindle length setting (1.55m outside)
1.4m spindle length setting (1.85m outside) as pictured on left
The sides now have 45º deflection to brush overhanging branches and vines to avoid catching.

Automatic speed and netting tension

Netting tension is easily adjusted (by turning a screw) to suit different strength nets. Once the tension has been set to suit the netting there is no need to adjust it again.

All the tractor driver has to do is drive down the row and stop only if the netting becomes caught up on the vine trellis. No controls need to be adjusted while driving (retrieving or applying netting).

Netting wound tight on steel spindles

Netting is stored from the vine on square steel spindles and end covers are fitted when in use. These covers have high sides and large sealed ball bearings for easy operation.

New netting supplied in bags or on narrow rolls can be applied straight over the vine with the NetWizz without the need to first wind onto spindles.

The NetWizz comes with 8 spindles which are stored in the holder. These spindles are 50mm square x 1.6mm thick, being 1.1m long for standard setting and 1.4m for the wide setting.

Controlled net unrolling tension

When feeding out netting to cover the vines, the spindle hydraulic drive is simply disengaged which allows the net to unroll. A brake can be lowered onto the roll, allowing it to unroll at a set light tension regardless of diameter and also prevents over-run.

For single and multiple row or full canopy cover netting

The NetWizz is a fully proven market leader. Safely handling different types and widths of netting, over multiple rows or by rotating the top loop 30º to apply or remove from single rows and full canopy cover.

Improvements 

After 20 years, we have redesigned all NetWizz models. Frames are now much stronger, hydraulic motors 40% more powerful & 25% faster winding, top loop and mast from bigger steel, spindle drive coupling stronger, spindle covers stronger, bottom steel side & top plate now twice as thick, more compact, safer, easier to operate. High Lift Mast & arms made from heaver steel raises higher.

 

Roll Spike

Efficient handling of netting rolls.

A roll spike is available, which is clamped to fork-lift or front-end loader forks and is then inserted into the spindle. This system allows rolls to be stacked on top of each other for safe and very compact storage. It is strongly recommended when handling large rolls of netting.    (OPTIONAL EXTRA)
