The BCS Dual/Double Action Sickle Bar Mowers step it up a notch from its single-blade predecessor. This unique and fast sickle bar attachment mows using two moving blades, each moving in equal and opposite directions. The dual-action reduces vibration for the operator and increases efficiency in mowing applications. A common task for the dual action sickle, is cutting pasture for hay, specifically the version WITH "fingers".
BCS offers two versions of the Dual Action Sickle Bar: Dual Action WITH Fingers and WITHOUT Fingers. Both feature riveted guards on the lower teeth to allow for no clogging of mowed materials, and have spring-loaded blade tensioners for decreased vacillation.
The version with fingers is formerly known as "duplex", and has been available for many years. Compared to the standard sickle bar, it reduces vibration and enables mowing in faster speeds.
The version without fingers is better suited to use in woody material such as saplings, because the version with fingers can be prone to breakage. This version also includes heavier-duty self-adjusting tensioners.
Both versions of the Dual Action Sickle Bar are much wider than the wheelbase, so you can easily trim along slopes, ponds, under fences, and other low-clearance places you wouldn’t dare take a traditional mower. It can also be used for forage harvesting, most notably hay.
Self-adjusting tensioners are a key feature of all Dual Action Sickle Bar Mowers. Instead of static clamps as on the single-action version, moving arms with spring-loaded down pressure maintain optimal contact between the knives and the ledger plates. This reduces required maintenance because the owner won't have to manually adjust the clamps as they wear over time, being careful not to over-tighten them.
Dual/Double action Sickle bar cutter features:
NOTE:Dual/Double action sickle bar cutters should be run at 1/2 throttle or less !!! They do not need much power to do their job. Running the sickle bar cutter over 1/2 throttle, will result in premature fatigue/wear of the sickle bar components, it will consume more fuel AND cause extra vibration that will be transferred back to the operators body. If you need to mow faster, make sure to have a 2 wheel tractor with 3 working speeds.
The Single Action Sickle bar cutter is also available as a more "cost effective" option for certain types of mowing. It does have quite a bit more vibration and must be run slower than the Dual/Double action sickle. The single action sickle should be run at 1/3 throttle or less!
