Original practice questions written to the published syllabus · not past papersFarm Machinery Training & Testing Institutes (Budni, Hisar, Anantapur, Biswanath Chariali) is a professional certification run by Ministry of Agriculture & Farmers Welfare, Government of India, for candidates in India. Not an exam: short training courses and machinery testing (commercial, batch, confidential, CMVR).

How farm machines are made: joining, casting, machining, heat treatment and measurement, up to building a prototype.

A technician must clear a blockage inside a powered workshop machine. What should be done first?
C. Isolate the supply, lock it off and tag it, then release or block any stored energy
Lockout–tagout isolates the energy source so no one can restart the machine, and stored energy in springs, hydraulics or raised parts is released or blocked. A start button can be pressed by someone else, gloves near moving parts are an entanglement hazard, and removing the guard first exposes the hazard while live.
Why must oxygen regulators and cylinder fittings never be lubricated with oil or grease?
D. Oil and grease can ignite violently on contact with high-pressure oxygen
Hydrocarbons in pure, high-pressure oxygen can ignite spontaneously and burn explosively; this is a fire and explosion hazard, not a maintenance nuisance. Diaphragm wear, arrestor clogging and tip soot are not the reason for the rule.
Why are power sources for manual shielded metal arc welding built with a constant-current (drooping) characteristic?
A. Arc length varies with the welder's hand, and current then changes only a little
With a steep drooping curve, a change in arc length changes voltage much more than current, so heat input stays steady despite hand movement. Fixed voltage with self-regulating arc length is the constant-voltage principle of wire-fed GMAW. No characteristic makes shock impossible.
A crack is suspected at a fillet weld on an austenitic stainless steel sprayer tank. Which surface test should be used?
B. Dye penetrant testing
Austenitic stainless steel is essentially non-magnetic, so magnetic particle testing will not work; dye penetrant finds surface-breaking cracks in any non-porous material. Hardness and spark tests identify material properties, not cracks.
A rough cast hub for a thresher pulley is irregular in shape and its bore must be set accurately true to a machined face. Which work-holding device suits it?
D. A four-jaw independent chuck set with a dial indicator
Each jaw of a four-jaw chuck moves independently, so irregular work can be clocked true to the feature that matters. A three-jaw chuck centres on the rough outside, collets need accurate round stock, and centres need centre holes in a shaft-like part.
Before mounting a new vitrified grinding wheel, a technician taps it lightly with a non-metallic object and listens. What is the purpose?
A. A clear ring shows the wheel is sound; a dull sound suggests a crack
The ring test detects cracks: a sound vitrified wheel rings, a cracked one sounds dead, and a cracked wheel can burst at speed. It does not identify grit size or grade and does not condition the wheel.
Several bolt holes must be drilled in a heavy cast gearbox housing that is awkward to move. Which machine suits the job?
D. Radial drilling machine
The radial drill's head travels along a swinging arm, so each hole can be reached without moving the heavy work. A bench drill is for small parts; a gang drill moves the work between fixed spindles; a horizontal mill is not suited to drilling scattered holes.
A small firm builds cultivator frames by welding square tubes. Hitch-pin positions vary by several millimetres from frame to frame, and some frames twist. What is the most effective remedy?
C. A welding fixture that locates every member and holds it during welding
A fixture locates each member to the same datums and restrains distortion, so hitch geometry repeats. Higher current adds heat and distortion; changing section does not fix location; inspection finds bad frames but does not prevent them.
A cracked grey cast-iron gearbox housing of a farm machine is to be welded in the field. Which practice reduces the risk of new cracks?
B. Nickel-based electrodes in short beads, each peened while hot, with low heat input
Cold welding of cast iron uses nickel-rich filler, which stays ductile, in short beads peened to relieve shrinkage stress; crack ends are drilled first. High heat input with steel filler forms hard martensite and white iron at the fusion line and cracks; quenching makes this worse.
Before welding a fatigue crack in a mild-steel cultivator frame, the technician drills a small hole just beyond each end of the crack. Why?
A. The hole blunts the crack tip, so the crack does not keep running during repair
A crack tip is a sharp stress raiser; drilling replaces it with a round hole that lowers stress concentration and stops the crack spreading. The root cause of the crack must also be corrected. Venting, reference points and weight are not the purpose.
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.
