Model 780 the latest Hydrostatic model from BCS and the first of the StarGate series of tractors. The Stargate series set out to redefine the two-wheel tractor with a focus on Performance, Reliability, Ergonomics, Safety, & Ease of Use. Model 780 features an updated and compact hydrostatic transmission, the PowerSafe hydro-mechanical clutch, AND more ergonomic reversible handlebars for both front- and rear-mount attachments.
Hydrostatic transmissions allow the machine’s speed to be continuously adjusted without having to stop and change gears. The continuous variation of speed in either direction occurs independently of the PTO and engine RPM.
The 780 employs the comfortable “EasyGrip” hydro lever on the handlebar for instantaneous changes to ground speed and direction of travel without altering the performance of the attachment and without the need to shift gears or change the throttle setting.
With a monolithic transmission structure made of light alloy, the machine is easily maneuverable and more compact than other hydrostatic units. This innovation allowed for an active and passive oil cooling system inside of the gearbox and via airflow from a dedicated fan without the need for external cooling coils.
The PTO is mechanically connected to the engine for minimal energy dissipation, allowing for more power to be transferred through fewer gears directly to the attachment for better performance.
Operationally, hydrostatic drive is a real game changer. Not only is the single lever control ultimately user-friendly (and fun), it also expands the functionality and productivity of the BCS attachments.
Example 1: When mowing the “outback” with the rotary brush mower, the engine is always at full throttle to assure maximum blade tip speed. As you move from tall weeds to woody brush, use the hydro lever to reduce your ground speed; thereby increasing the number of “cuts” per forward foot of travel. This overcomes the greater resistance of the brush, followed by the ability to instantly return to your higher weed-mowing speed.
Example 2: When trimming under fences, bushes, or low-lying limbs, the necessary back-and-forth motion of the mower is as simple as moving the hydro lever forward and backward.
Example 3: When mowing down a steep pond bank, the dynamic neutral of the hydrostatic enables the operator to stop and reverse direction, regardless of position, without fear of the mower freewheeling out of control.
Upgraded and more ergonomic handlebars allow for more relaxed working conditions and added shock absorption allows for smoother operation, especially with a sickle bar mower.
Other features of the 780 include Differential Drive and on-demand differential lock for posi-traction. Maneuverability is enhanced by individual steering brakes which are particularly useful when operating heavier attachments like the 35" Flail Mower. An external mechanical disengagement lever of the wheel axle allows the machine to be moved even with the engine off.
The 780 is powered by the dependable Honda GX390 engine, available in recoil or electric start. And that power is transferred directly to the PTO through the PowerSafe clutch. This patented, hydro-mechanical clutch is a super-durable multi-plate clutch, cooled by circulating oil, and designed to withstand the rigors of operating high torque implements, such as the Flail Mower and Chipper/Shredder, during long hours of operation. With the updated design, BCS Stargate series has simplified maintenance having the hydrostatic oil filter shared with the clutch circuit and the entire hydrostatic pump easily accessible on the unit.
