Originally introduced in the 1980s, the Dyna-Drive quickly became one of the best selling Bomford products because of its simplicity, reliability and low operating cost, prior to production ceasing 10 years ago.
The decision to reintroduce the Dyna-Drive comes as arable farmers look to control blackgrass and other weeds by using a cultivator or harrows to quickly go over stubbles and encourage weed seeds to chit so that they can then be sprayed off prior to drilling.
In this respect, the Dyna-Drive is the ideal machine. One of the major design features is that because the two rotors are not PTO-driven, this reduces power requirement, so forward speed is not restricted allowing large areas to be covered quickly, so reducing operating cost in time and fuel.
Initially the Dyna-Drive will be available in working widths of 2.6m, 3.0m, 4.0m and 5.0m. Minimum suggested power requirements range from 80hp up to about 160hp for the 5.0m model. At an average forward speed of about 12km/hr, typically outputs of 3.13ha/hr up to 6.0ha/hr can be easily achieved, depending on soil type.

The Dyna-Drive comprises of two ground-driven rotors, linked by a heavy-duty Duplex drive chain. Fitted with alternating heavy-duty left and right twisted tines, the forward tines on the front rotor initially penetrate, then lift and break-up even the hardest of soils. The backward facing tines on the rear roller then firm the broken-up soil and leave a level finish. If required, a crumbler roller or packer roller can also be fitted to the rear of the Dyna-Drive for further consolidation on heavier soils.
“Judging by our sales of replacement points, it’s surprising quite how many machines there are still out there in regular use,” Bomford’s Chris Tucker said. “The Dyna-Drive was very popular throughout Europe, and the reaction to the new machine at Agritechnica 2013 was incredible and resulted in potential orders for up to 50 machines.”
Prices for the new Dyna-Drive range from £11,000 for the 2.6m model to £20,500 for the widest 5.0m version (prices correct at January 2014).
