How tractor engines work and how their performance is measured — the single most reliably examined farm-power topic.
Our 33 Farm Machinery Training & Testing Institutes questions in this subject: 16 easy, 13 medium, 4 hard, across 14 units.
Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
These 10 were written to Farm Machinery Training & Testing Institutes and are not shown on any other exam's page.
The engine most commonly fitted to a walk-behind two-wheel power tiller is a
D. single-cylinder horizontal diesel
Power tillers use a small single-cylinder horizontal four-stroke diesel, often water-cooled with a radiator or hopper. Multi-cylinder turbocharged diesels power four-wheel tractors.
In a four-stroke engine the camshaft rotates at
A. half the crankshaft speed
Each valve opens once per cycle, and a cycle takes two crank revolutions, so the camshaft (and the injection-pump camshaft) turns at half crank speed.
The delivery valve with a retraction (unloading) collar in an injection pump
B. drops line pressure quickly at end of delivery so the nozzle closes sharply without dribbling
As the valve seats, the collar withdraws a small volume from the high-pressure pipe, which unloads it and prevents after-dribble, while keeping residual pressure for the next stroke.
In an oil-bath air cleaner, dust is removed mainly by
C. turning the air sharply over an oil surface and through oil-wetted mesh
Air impinges on oil, which captures heavy particles, and the oil-wetted mesh traps finer dust. Oil must be kept at the mark and changed when sludged. Pleated paper is the dry-type cleaner.
Ethylene glycol is added to engine coolant mainly to
A. lower the freezing point (and, with inhibitors, protect against corrosion)
Glycol-water mixtures freeze at a much lower temperature than water and also boil higher; inhibitors protect metals. Their specific heat is lower than water's, not higher.
A tractor overheats during wheat harvest-season field work although the coolant level is correct and the thermostat has been tested good. The first thing to check is
C. radiator fins blocked by chaff and dust, and the fan-belt tension
In dusty crop work, clogged radiator fins and a slack fan belt are the commonest causes of overheating once coolant level and thermostat are ruled out.
In the engine-oil grade SAE 15W-40, the '15W' refers to
D. the oil's low-temperature (winter) viscosity grade
SAE J300 multigrades meet a winter (W) low-temperature grade and a 100 °C grade (here 40). W stands for winter, not weight.
The bypass valve in a full-flow oil filter
B. bypasses a clogged element
If the element clogs, the bypass opens so bearings are not starved, but the oil is then unfiltered, so filters must be changed on schedule. Pump pressure is limited by the separate relief valve.
On test, a tractor engine runs at 2,310 rev/min at maximum no-load and 2,100 rev/min at rated full load. Taking governor regulation as (no-load − full-load speed) ÷ full-load speed, its value is
C. 10.0%
(2310 − 2100)/2100 × 100 = 10.0%. Dividing by the no-load speed gives 9.1% and by the mean speed 9.5%; always use the definition the question states. 110.0% divides no-load by full-load speed without subtracting.
On test, an engine delivering 30 kW consumes 50 mL of fuel (density 0.84 g/mL) in 20 s. Its BSFC is closest to
B. 252 g/kWh
Fuel mass = 50 × 0.84 = 42 g in 20 s → 42 × 180 = 7.56 kg/h. BSFC = 7.56/30 = 0.252 kg/kWh = 252 g/kWh. Ignoring density gives 300 g/kWh (a volume rate in mL/kWh); dividing by density instead of multiplying gives 357. 42 g ÷ 30 kW ignores the 20 s timing and gives 1.4 g/kWh.
This plan follows where our questions actually fall, so the time goes where the marks are likely to be. It is our reading of the syllabus, not the exam body's weighting.
Read the manual chapters for these first and do every worked question you can find on them.
Aim for one sitting per unit, then mixed questions across them.
Learn the definitions, classifications and standard numbers; these units are more often recalled than worked.
Come back to these after a first pass, untimed, and read every explanation, including for the options you rejected.
Do these early in revision so they are fast on the day.
