Comb Harrow, Hatzenbichler

Introduction

Comb Harrow Introduction

A multi-purpose tool, the Comb Harrow consists of fine spring tines, mounted on a contour-flexing frame, with working widths of 1.5m to 24m.

Its main use is for weeding crops and reducing chemical costs, and may also be used to break up capped soil or as a conventional harrow for seedbed preparation / harrowing.

Features

Comb Harrow features

Ultimate contour following ability for uneven ground

Even pressure is applied across every inch of the working width. The frame adapts to the ground contours with additional pressure being supplied from the accumulator to even the harrowing pressure across the working width.
Active harrow bed suspension on the implement frame.
An flexible harrow bed adapts to ground undulations.

Flexible bed

The flexible design of the tine beds allow them to follow the contours of the land ensuring effective coverage and even tine pressure. Each 1.5m bed has 48 tines spaced at 30mm centres apart and as well as ensuring good tine pressure onto the ground, this design allows it to self-clean as it moves through the weeds. 

Adjustable tine angle

Quick and simple tine angle and pressure adjustment, ground conditions will determine how aggressive tine pressure needs to be for effective harrowing. On the OPICO Comb Harrow there are 10 tine angle settings so pressure can be altered, ensuring the vibrating action of the triple coil spring tine can be maximised.

The oil hardened spring wire has three times the service life of a normal sprung steel wire. 

Construction

The construction of the headstock consists of interlocking pieces of steel so the Comb Harrow doesn't just rely on the welding for strength. The frames and beds are powder-coated and most of the other steel parts are anodised so your harrow will stay in good working order and looking newer for longer.

Folding system

When in transport position, the hydraulic and scissor folding models fold up between to 2.5m and 3m dependant on the model of Comb Harrow. This allows for easy transportation on the road and through narrow gateways.

Models

1.5m - 3.0m Non-Folding Comb Harrows

The rigid, non-folding Comb Harrows consist of 3 models, 1.5m, 2m and the larger model at 3m wide.

All three models can be supplied with either Category 1 or 2 pins if specified at the time of order.

4.5m - 8.0m Hydraulic folding Comb Harrows

The hydraulic folding models consist of 7 widths, 4.5m, 5m, two 6m versions, 6.4m, 7.5m and 8m.

The 6m comes in two different formats, one unit has 3x2m sections the other has 4x1.5m sections. The 3 section unit is able to fold down to 2.5m for transport which enables easier movement through narrow gateways and down the road. On the other hand the 4 section unit folds to 3m for transport but has improved contour following ability in the field.

9.0m - 12.4m Scissor folding Comb Harrows

The 9m, 10.5m, 12m, 12.4m and 15m uses a hydraulic scissor folding system to keep this wider range of machines to a transport width of or under 3m. The 15m machine is also available in a semi-mounted model that has a smaller transport height and width but needs more HP as its weight is more.

15.0m - 24.0m Semi-Mounted Scissor folding Comb Harrows

The 15m, 18m, and the big 24m uses a semi-mounted hydraulic scissor folding system to keep the wider range of the machines to a transport width of or uder 3m.
