The BCS Two Wheel Tractors, specifically models 710, 728, 738, 740, and 750, are power units designed for various landscape machinery tasks. These tractors are equipped with a PowerSafe® Clutch, emphasizing safety and operational control.
Function Description:
These two-wheel tractors serve as versatile power units for a range of implements used in landscaping and ground care. They are designed to be operated by a single user, providing power to various attachments for tasks such as tilling, mowing, and other agricultural or horticultural activities. The PowerSafe® Clutch is a key safety feature, designed to stop the machine when released, preventing uncontrolled movement.

Usage Features:
The tractors feature a comprehensive set of controls for efficient and safe operation:
- OPC Lever (A): Red lever that stops the machine when released, integral to the PowerSafe® Clutch system.
- Engine Stop Lever (B): For stopping the engine.
- Clutch Control Lever (C): Engages and disengages the clutch.
- Gear Lever (D): Selects different gears, with gear locations shown on the selector.
- PTO Lever (E): Engages the power take-off for implements. It includes a safety device to prevent engagement with reverse gear.
- Throttle Lever (F): Controls engine speed.
- Handlebar Height Adjustment Lever (G): Allows adjustment of handlebar height for operator comfort.
- Steering Column Swivel Lever (H): For swiveling the steering column.
- Forward/Reverse Lever (L): Selects forward or reverse movement. Requires clutch engagement before use. Position depends on whether handlebars are over the engine or implement.
- Differential Lock Lever (M): Locks the differential for improved traction.
- Parking Brake Lever (N): Engages the parking brake.
- Right Brake Lever (O) and Left Brake Lever (P): Individual wheel brakes for steering and control (on models 740 & 750).
Starting Procedures:
- Petrol Engine: Check oil (10w/40) and fuel (unleaded petrol, 1" air space). Turn fuel tap ON. Set choke ON if cold. Ensure gear lever (D) is neutral and PTO lever (E) is disengaged. Apply half throttle (F). Move engine stop lever (B) to 'ON'. Pull recoil start handle gently until it engages, then give a strong pull. Release choke after a few seconds, return throttle to idle.
- Kohler Diesel Engines: Check oil (10w/40) and fuel (diesel). Ensure gear lever (D) is neutral and PTO lever (E) is disengaged. Apply 3/4 throttle (F). Move engine stop lever (B) to 'ON'. Pull recoil start handle gently until it engages, then give a strong pull. Return throttle to idle once started.
- Yanmar Diesel Engines: Check oil (10w/40) and fuel (diesel). Ensure gear lever (D) is neutral and PTO lever (E) is disengaged. Apply 3/4 throttle (F). Move engine stop lever (B) to 'ON'. Press and hold decompression lever. Pull recoil start handle gently until it engages, then slowly pull over 2-3 times to prime. Release decompression lever and pull over until compression is felt. Press (do not hold) decompression lever and give a strong pull to start. Return throttle to idle once started.
Operation:
- Set handlebar height (G).
- Hold handlebar, pull up clutch lever (C).
- Depress OPC lever (A), select speed (D).
- Ensure forward/reverse lever (L) is in correct position (back if handlebars over engine, forward if over implement).
- Engage PTO lever (E) for implement drive (pull towards you if handlebars over engine, push away if over implement).
- Release clutch lever (C) slowly and fully, keeping red machine stop lever depressed.
- Adjust throttle (F) as per implement manual.
- Commence work.
Stopping Procedure:
- Close throttle (F).
- Engage clutch lever (C).
- Locate gear lever (D) in neutral.
- Disengage PTO lever (E) backwards.
- Release clutch lever (C).
- Release OPC lever (A) completely.
- Move engine stop lever (B) to 'STOP'.
- WARNING: Exhaust cover may be hot - do not touch.
Attaching Implements:
- Models 710-740: Implements mount directly to the flange (Fig. 12, A) or with a quick release assembly (Fig. 13, C). Ensure fastening nuts (Fig. 13, D) are tight.
- Model 750: Implements mount to the machine coupler (Fig. 14, A) by attaching the implement's coupler (Fig. 14, C). Fitting/removal is by rotating knob (Fig. 15, R) (clockwise to lock, anti-clockwise to unlock). Ensure fastening nuts (Fig. 15, D) are tight.
Maintenance Features:
- Engine Maintenance: Refer to engine manufacturer's manual.
- Check engine oil level (10w/40) every day/week.
- Remove spark plug cap after every hour of operation, replace after checking oil.
- Gearbox & Controls Maintenance:
- Every Day: Check gearbox oil level (page 13), check nuts & bolts.
- Every Week: Check engine oil level (10w/40), check nuts & bolts, ensure clutch cable free play, check tyre pressure (20psi), lubricate control cable/linkages, check control cable operation, check operation of safety devices.
- Every Month: Check tyre pressure (20psi), grease gear speed detent ball.
- Every 6 Months: Change gearbox oil (page 13), grease gear speed detent ball.
- Gearbox Oil Level Check: On a level surface, oil level should be between two notches on the dipstick (Fig. 2, D).
- Gearbox Oil Filter Replacement:
- First 2 Weeks or 30 Hours: Replace gearbox oil filter ONLY (Fig. 1, A), part number 58056249.
- Every 100 Hours or 12 Months: Replace gearbox oil filter (Fig. 1, A), part number 58056249.
- To replace: Remove old filter with spanner. Smear oil on new filter's rubber gasket. Mount and tighten new filter by hand only.
- Gearbox Oil Change (Every 100 Hours or 12 Months): Remove drain plug (Fig. 3, B). Replace filter. Clean drain plug and refit. Fill with correct oil and quantity. Run machine 2-3 minutes, recheck oil level.
- Cleaning: Do not turn the machine on its side for cleaning. Pressure washing can remove lubricating grease.
- Lubrication: Keep all linkages, especially the gear speed lever detent ball, well greased.
Storage:
For long-term storage:
- Empty carburettor and fuel tank (or add fuel stabilizer).
- Empty engine oil.
- Petrol engine: Lubricate cylinder with a few drops of engine oil through plug hole, turn engine over several times without starting.
- Diesel engine: Remove injector, pour a little oil into the hole.
- Clean engine and machine thoroughly.
- Before restarting, check all security devices.
Safety Instructions:
- Always start engine in open air.
- Do not smoke when refuelling.
- Do not mix oil with fuel.
- Stop engine before adjustments, refuelling, moving, cleaning, or when unattended.
- Use only designed fuel containers, refuel outdoors, replace cap securely.
- If petrol spills, move machine away and allow vapours to dissipate before starting.
- Do not remove safety guards.
- Keep hands and feet away from moving parts; do not attempt maintenance while running.
- Clear work area of objects before starting.
- Do not allow children or uninstructed persons to operate; keep animals away.
- Wear suitable clothing, including good grip footwear. Avoid loose garments.
- Know how to stop in an emergency.
- Never interfere with engine control settings.
- Never select reverse gear with back to an immovable object.
- If a fault develops, contact supplier immediately.

- Operator is responsible for accidents/hazards.
Risk Assessment Summary:
- General: Use by trained operators only.
- Machine tipping over: Low risk, do not use on slopes over 25°.
- Machine running away: Low risk, red stop lever disengages drive if handlebars released. Check operation before use.
- Lacerations: Medium risk, remove spark plug cap before maintenance/cleaning. Wear gloves when cleaning/removing debris.
- Machine reversing and jamming operator: High risk, never reverse with back to a wall or similar object.
- Burns: High risk, be careful of hot exhaust. Turn off machine before refuelling. Allow 1" air space in fuel tank.
- Handlebar adjustment: Low risk, set height/sideways position before operating, never while moving.
