LOGIC SUPER HARROW LSH150/200 uses Einbock® technology, which pioneered organic weeding and plant stimulation. Grass paddocks are rejuvenated by the action of combing, to aerate the soil surface and remove dead grass. It pulls out choking weeds like chickweed, as well as evenly spreading molehills and dried muck.
This system encourages grass growth over a longer season, with healthier grazing conditions and reduced fertilizer costs. It is equally at home on many all-weather surfaces where maintenance involves levelling and re-incorporating the top surface before rolling, e.g. running tracks and hockey pitches, etc.
Width options of 1.5m or 2.0m allow fast work rates, feature adjustable tine settings for various conditions and easy transport facility. The unit is raised and lowered by an electric ram actuator with remote control, this allows use behind a wide range of vehicles including ATVs, tractors or 4 x 4. The Logic Super Harrow is built with high quality components throughout, to ensure durability and long life.

HARROWS COMPARISON
There is a wide choice of harrows to choose from when deciding which product would be best suited to your requirements.
Factors to be taken into consideration when deciding which model to go for are :-
a) Capacity of the towing vehicle.
b) Size and frequency of the area to be treated.
c) Ground conditions eg. grass, all-weather surface, or preparing soil for landscaping etc.
d) The requirement to raise the harrows for transport between fields.
e) Cost.

BASIC CHAIN HARROWS are ideal for smaller areas and can be pulled by a mid sized ATV or small car. Their design hasn’t changed for 50 years, so they are a well - proven product. When more aggressive treatment is required, repeated use over the same area will eventually do the job.

TRAILED CHAIN HARROWS are suitable for areas of up to 10 hectares, where a larger ATV or 4x4 type towing vehicle will improve the performance of the harrow by towing at higher speeds, with the raise and lower frame holding down the web to prevent it from bouncing. The raise and lower facility comes into its own moving from one field to another and returning to store.

SUPER HARROWS are designed for use behind the largest ATVs, small tractors or 4x4 vehicles. They provide adjustment to facilitate the lightest of touches, ideal for all-weather surfaces, through a whole range of settings up to a really aggressive mode suitable for thatch removal, muck and mole hill levelling or soil preparation. Electrically controlled raise and lower allows use behind a wide range of vehicles with operation from the drivers seated position.
