DescriptionWhy buy the William Hackett H-HG04 Chain Harrow?

The H-HG04 is the entry size in William Hackett's fixed-tine family. It's the one a smallholder or yard manager can genuinely pull behind an ATV or 4x4 — the wider mats want a tractor in front of them. At 4 ft across it slips through paddock gateways and works neatly around single-horse turnout.

Tears thatch and knocks down mole hills

Fixed tines, one-way pull, aggressive bite. The mat scarifies harder than a reversible pattern — it rips matted thatch out of grass, opens compacted topsoil and flattens mole hills in a single pass. Run it over the menage and it keeps the surface even for schooling, too.

Light enough for a quad, heavy enough to work

At 37 kg the harrow drags behind a quad or 4x4 without bogging into soft ground, but it carries enough weight on the tines to bite. The drawbar is a heavy-duty steel tube with a chain draft, so pull stays even across the full width of the mat.

  • Working width: 4 ft — smallest in the family, sized for single-horse paddocks and ATV gateways
  • Weight: 37 kg — drags behind a quad without bogging
  • Ring/pin hitch — couples to ATVs, 4x4s and compact tractors
  • Fixed-tine, one-way aggressive action — scarifies harder than a reversible mat
  • Carbon-steel construction with heavy-duty steel drawbar tube and welded spacer bar
  • Chain draft to the hitch keeps pull even across the mat
  • British-made by William Hackett
  • Overall dimensions: 120 × 152 cm

I’m happy to endorse the product as below. Good luck in your endeavours. I have found the small chain harrow well made and easy to use. It is just about manageable by one person. I tow it around the edges of my small-holding fields behind an old landrover using just the tow bar but avoiding reversing. It is sturdy, quite easy to clean up and seems happy being stored outside with any slight rust rubbing off when the harrow is next used. If I get the time of season right it knocks back the encroaching bracken, brambles and nettles with two or three applications in a year. I would give it 5 out of 5 for doing what is demanded of it; and speed of delivery and help unloading were all first class.

I actually bought this for a neighbour who had a larger harrow that was better for me. As far as I am aware he has been very happy with it.

The Harrow did the job required. It was the right size for my mini tractor and the size of our fields, so I’d rate it 5 for my needs but they were very specific.

We are very pleased with our harrow and have had no issues at all. It was very good value for money and is perfect for our needs (harrowing horse manure into our paddocks).

It’s a simple bit of kit that’s done its job until next season and will sit in the yard until called upon.

I really like this small harrow, it’s easy to use and small enough to store. I do apply a little bit of extra weight for the harrow, normally consisting on a tractor tyre when harrowing the field but for my arena this is not required it works perfectly on its own as it is. I would highly recommend this piece if equipment!

I am very satisfied with this harrow and would recommend it to others. It is well made and did the job helping me level a paddock for sewing grass seed to cover patches. I would give this harrow 5/5.

Chain Harrow arrived in good time

Chain Harrow arrived in good time. Delivery guy helped to unwrap and unload it. Easy to use and has helped to level the ground well. Also very effective in removing moss and unwanted thatch from lawns.
