Vineyard Netting Applicator
NetWizz Standard Auto Tension
NetWizz Standard 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.

- Fast, safe removal of netting without tears
- Netting wound tight on steel spindles
- For single & multiple row or full canopy cover netting
- Self loading and unloading of netting rolls
- High lift mast option for fruit trees
- Shear bolt protection for top loop & mast
- Very compact & safe design
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 loop & mast
The NetWizz mast incorporates a shear bolt assembly which breaks a small bolt, preventing the top loop and mast from damage. To work around power poles, trees and for transport the top loop easily rotates 90° and is self locking in five positions. The mast is telescopic and is raised and lowered using its winch and can be locked at seven height settings.
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. NetWizz frame is adjustable in width to handle very large rolls of netting.
Automatic speed and netting tension
|Self-loading and unloading|
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
|Easy tension adjustment|
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 (shown left) or by rotating the top loop 30° to apply or remove from single rows and full canopy cover.
