The rotary power harrow, manufactured by Thivierge of Quebec, is an excellent attachment for preparing seed beds prior to planting. We offer it in two sizes: 21″ and 32″.
It includes several sets of tines, which each rotate about a vertical axis (not horizontal like a rear tine tiller). Thus, they stir the soil in a motion similar to that of an eggbeater.
The horizontal stirring action of the harrow avoids disturbing soil layers and leaves soil structure intact, unlike the rototiller, which mixes topsoil with subsoil. This is healthier for your soil because it does not disrupt the soil microbiology as much. The horizontal action also reduces weed seed germination by not bringing new weed seeds already in the soil to the surface. In addition, soil compaction is less, helping to prevent the formation of hardpan.
The power harrow floats independently of the horizontal axle of the tractor, allowing it to follow and level out rough terrain.
The harrow now features what BCS calls the “Josephine” lever, which allows you to quickly move the implement into the transport position at the end of the row to simplify turning. After the turn, you can use the lever to quickly return the implement to its previously set depth.
- Easy depth adjustment, from 0 – 5 inches
- The horizontal stirring motion (like and egg beater) preserves the soil structure, reduces compaction and helps to minimize disruption of soil microbiology.
- Metal mesh roller helps to level the soil.

Size and Compatibility
As mentioned above, the power harrow is available in both a 21″ and 32″ size. The 21″ harrow is designed to work with BCS tractor models 722 and up. The 32″ model works with models 732 and up.
Market gardeners often choose the 32″ size harrow, which is ideal for working with 30″-wide garden beds. For both sizes, the depth is adjustable from zero to 5″.
We recommend using 12″ wheels on the walk-behind tractor when using the harrow with models 749 and up.
Use of the harrow requires a Bumper Weight Kit, which improves balance and makes turning easier at the end of the row. It also requires the use of a Quick Hitch bushing.
