CGM Equipment Operation & Safety Procedures 2 — Questions and Answers
Question 1: When operating a zero-turn radius mower on a slope, what is the maximum recommended grade for safe operation on most commercial units?
- 10 degrees
- 15 degrees (Correct answer)
- 20 degrees
- 25 degrees
Correct answer: 15 degrees
Most commercial zero-turn mowers are rated for slopes up to 15 degrees; steeper grades risk rollover due to the rear-wheel-drive pivot steering.
Question 2: A grounds manager discovers hydraulic fluid leaking from a skid steer loader before a scheduled job. The proper course of action is to:
- Add fluid and monitor during operation
- Tag the machine out of service and report to maintenance (Correct answer)
- Reduce workload and operate at lower RPM
- Apply a hydraulic sealant to the leak point
Correct answer: Tag the machine out of service and report to maintenance
Hydraulic leaks require tagging the machine out of service per lockout/tagout (LOTO) procedures because failure under pressure can cause catastrophic injury.
Question 3: Which type of fire extinguisher is most appropriate for a fuel fire on a gasoline-powered grounds vehicle?
- Class A (water-based)
- Class B (dry chemical or CO2) (Correct answer)
- Class C (CO2 only)
- Class D (dry powder)
Correct answer: Class B (dry chemical or CO2)
Class B extinguishers are rated for flammable liquid fires including gasoline, which is the fuel source in most grounds equipment.
Question 4: What is the primary purpose of the rollover protective structure (ROPS) on a compact utility tractor?
- Reduce wind drag on slopes
- Protect the operator if the tractor overturns (Correct answer)
- Mount additional lighting equipment
- Provide structural rigidity for loader attachment
Correct answer: Protect the operator if the tractor overturns
ROPS creates a protective zone around the operator's seat to prevent crush injuries during a rollover event.
Question 5: When refueling a hot gasoline engine in the field, the safest practice is to:
- Refuel immediately to maintain schedule
- Allow the engine to cool for at least 2 minutes (Correct answer)
- Fill slowly while the engine idles
- Refuel only in covered, shaded areas
Correct answer: Allow the engine to cool for at least 2 minutes
Allowing the engine to cool prevents fuel vapor ignition from heat near the carburetor, exhaust, or engine block.
Question 6: A crew member is mowing near a storm drain opening. Which hazard specific to this scenario requires immediate attention?
- Excessive noise near the drain grate
- Risk of the mower deck dropping into the opening (Correct answer)
- Fuel contamination of the stormwater system
- Vibration damage to underground pipes
Correct answer: Risk of the mower deck dropping into the opening
Mower wheels or the deck can drop into drain openings, causing the machine to tip suddenly and potentially injure the operator.
Question 7: According to OSHA 1928.57, which of the following is required when operating a tractor without a cab in areas where workers may be overhead (e.g., under trees)?
- Hard hat for the operator only
- High-visibility vest and boots
- ROPS and seatbelt in use (Correct answer)
- Spotter stationed nearby
Correct answer: ROPS and seatbelt in use
OSHA requires ROPS and seatbelt use for agricultural tractors in circumstances where overhead hazards or rollover risk is present.
