Sample Gostekhnadzor Category F — Agricultural Combine Harvesters Practice Questions

Try these sample questions to review concepts for the Gostekhnadzor Category F — Agricultural Combine Harvesters exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 88+ question experience with AI tutoring.

1What safety precaution is strictly mandatory before an operator or technician performs any inspection, adjustment, or maintenance underneath a raised combine header?
A.Fit the mechanical safety stops on the lift cylinder rods and lower onto them
B.Rely on the hydraulic valve in neutral with the engine idling
C.Place loose wooden blocks under the skids with the hydraulics pressurised
D.Put the hydraulic selector in float so the header rests on the ground
Explanation: Occupational safety standards for self-propelled agricultural machines strictly prohibit working under a raised header supported solely by hydraulic fluid pressure. Hydraulic hoses or cylinder seals can rupture or leak without warning, causing the heavy header to drop instantly. Operators must install or swing down the mechanical safety lock stops onto the hydraulic lift cylinder piston rods and relieve hydraulic pressure onto the locks before entering the area underneath.
2When attaching a grain header to the feeder house of a combine harvester, what mechanical step must be completed before lifting the assembly into operating position?
A.Connect only the hydraulic couplers and raise the header to full height
B.That the lower hooks engage the pins and the latches are locked with pins
C.Tighten the feeder drive belt fully before lining up the brackets
D.Engage the threshing drive to check the feeder chain alignment
Explanation: During header coupling, the combine feeder house throat must enter the header frame pocket, aligning the upper beam and allowing the lower hooks to engage the mounting pins. The operator or assistant must close the locking latches and secure them with retaining cotter pins or spring clips before raising the header. Lifting an unpinned header creates an immediate risk of detachment and severe machine damage.
3What is the mandatory safety protocol when replacing a damaged knife section on a combine harvester cutterbar?
A.Keep the engine idling and jog the knife into position with the drive lever
B.Have a helper turn the drive pulley by hand while the knife is held from below
C.Engine off, key out, parking brake on, heavy gloves worn
D.Disconnect only the pitman arm and leave the engine running for the work lights
Explanation: Servicing reciprocating cutterbar knives carries high laceration and amputation risks. Safety regulations require shutting off the combine engine, taking the ignition key to prevent unauthorized start-up, setting the parking brake, and using cut-resistant work gloves. Knife sections are razor-sharp, and accidental movement of the driveline can sever fingers instantly.
4Why must an operator maintain a minimum clearance between the reel spring tines and the cutterbar knife guards during harvesting?
A.To stop grain dust being drawn into the cab air intake filter
B.To make the reel turn at three times the combine's ground speed
C.To keep the engine cooling fan working well in damp crops
D.So the tines do not hit the knife sections, causing sparks or breakage
Explanation: If the reel is adjusted too low or too far back, flexible steel tines can catch in the cutterbar fingers or hit the high-speed reciprocating knife sections. This contact breaks the knife sections, bends the reel bats, and produces high-energy friction sparks that can immediately ignite dry crop residue and straw dust.
5What is the correct procedure for securing a combine header onto its dedicated transport trailer (тележка для жатки) before moving on roads?
A.Seat it in the cradles, fit all clamping pins and lock the hitch pin and chains
B.Rest it loosely on the trailer beams and rely on its weight to hold it
C.Tie it down with ordinary rope and point the cutterbar towards oncoming traffic
D.Leave the feeder partly connected to the header to steady the trailer
Explanation: A detached header on a transport cart must be securely settled into the designated support brackets and locked down using manufacturer-supplied screw clamps, locking pins, or chains. The trailer tow hitch must be secured to the combine or tractor drawbar with a lock pin, cotter pin, and secondary safety chain. An unsecured header can shift or slide off during road transit, causing catastrophic collisions.
6What is the primary function of the feeder house reverser mechanism (реверс наклонной камеры)?
A.To increase the crop intake speed in high-yielding maize
B.To back a blockage out of the feeder without reaching in by hand
C.To reverse the cleaning fan and blow chaff off the radiator screen
D.To disengage the reel automatically whenever the combine slows down
Explanation: When an excessive slug of crop material plugs the feeder house elevator or header auger, the mechanical or hydraulic reverser rotates the conveyor chain backwards. This expels the congested material out of the feeder throat onto the header table, allowing the blockage to be cleared safely from the cab without manual pulling near moving conveyor slats.
7Why is regular inspection and lubrication of the cutterbar knife drive gearbox (МКШ / планетарный привод ножа) critical for field fire safety?
A.Without lubrication hydraulic fluid enters the engine cylinders
B.Overfilling makes the knife stroke longer than the legal limit
C.A dry or failing drive bearing overheats and can ignite chaff
D.Dry gears create interference that disrupts the GPS system
Explanation: The knife drive mechanism operates at high reciprocating frequencies (hundreds of cycles per minute) under heavy load. If the gearbox or wobble box lacks lubricant or develops failing bearings, friction temperatures can quickly exceed 300°C–400°C. In dry field conditions, accumulated fine straw dust and crop chaff resting against the hot housing will ignite, sparking a rapid field fire.
8If a stone or metal object enters the feeder house, what immediate action must the combine operator take?
A.Increase forward speed to push the object quickly through the drum
B.Engage the unloading auger to take load off the engine
C.Raise the cleaning fan speed to blow the object out of the back
D.Disengage the drives, stop the engine and check the stone trap
Explanation: When foreign material or a loud mechanical impact is detected in the feeder house, the operator must instantly disengage the thresher drive clutch and stop the engine. Attempting to force stones or metal pieces through the cylinder will destroy rasp bars, bend the concave, pierce the drum cover, and can trigger catastrophic internal sparks leading to an instant combine explosion or fire.
9Why is standing or walking directly in front of the combine header strictly prohibited while the diesel engine is running?
A.The reel, knives or header can move or drop without warning
B.Engine exhaust gas collects on the ground in front of the cutterbar
C.Radar emissions from the loss monitor are a radiation hazard
D.People in front make the automatic steering camera lock up
Explanation: Gostekhnadzor safety regulations strictly forbid anyone from standing in the operational sweep of the header while the engine is running. Even if drives are disengaged, valve failure, electrical short circuits, linkage movement, or accidental control bumping can engage the reel or cutterbar, or cause the raised header to drop, resulting in fatal crushing or mangling injuries.
10Under what condition is towing an agricultural header trailer behind a combine on public roads strictly prohibited?
A.If the header is wider than 3 m when mounted on the combine
B.If the combine's fuel tank is more than half full
C.If the air temperature is above 25 °C
D.If it lacks working lights and reflectors, or safety chains and pin retainers
Explanation: Traffic and agricultural machinery safety regulations mandate that any trailer towed on public roads must be equipped with working electrical signaling (taillights, brake lights, direction indicators), reflective rear red triangles, an approved drawbar coupling with a secured lock pin, and secondary safety breakaway cables or chains. Moving without functional lighting or safety chains is strictly prohibited.

Gostekhnadzor Category F — Agricultural Combine Harvesters: Suggested Study Strategy

1Learn the official operating bans: no road travel or firebreak crossing with a full grain tank, no towing by the steered axle, and no work with open engine panels or without an extinguisher.
2Know the starting rules: never start with the threshing unit engaged, by shorting the starter or by towing, and always check around the combine and sound the horn first.
3Memorise power-line clearances by voltage and always cross under lines at right angles.
4Review safe maintenance: stop the engine before any work on moving parts, wait for the chopper drives to stop, lower the header or fit the safety stops, and keep everyone off a combine on supports.
5Revise slope rules: never change gear on a descent or switch off the engine while coasting downhill.

Frequently Asked Questions
