CFB CFB Field Equipment & Maintenance Operations 2 — Questions and Answers
Question 1: What is the primary purpose of a verticut (vertical mower) operation on an athletic field?
- To establish seed-to-soil contact when overseeding
- To remove thatch and reduce grain in the turf canopy (Correct answer)
- To level low spots by redistributing soil
- To apply granular fertilizer into the rootzone
Correct answer: To remove thatch and reduce grain in the turf canopy
Verticutting uses vertically oriented blades to slice through the turf canopy, removing thatch buildup and reducing grain that can cause unpredictable ball bounce.
Question 2: Which piece of equipment is used to apply a uniform layer of soil or sand amendment across an athletic field surface?
- Sod cutter
- Topdresser (Correct answer)
- Scarifier
- Slit-seeder
Correct answer: Topdresser
A topdresser is specifically designed to spread and distribute sand or soil material evenly across a field surface for leveling and soil improvement.
Question 3: What safety check must be performed before operating a riding mower on an athletic field with installed irrigation heads?
- Verify the irrigation controller is in manual mode
- Confirm all irrigation heads are fully retracted below the cutting height (Correct answer)
- Check that the mower's fuel tank is less than half full
- Ensure the field drainage system is fully operational
Correct answer: Confirm all irrigation heads are fully retracted below the cutting height
Irrigation heads must be fully retracted below the mowing height before operating a mower to prevent blade damage, equipment damage, and projectile hazards.
Question 4: What is the recommended practice for maintaining paint striping equipment between uses on a multi-sport athletic field?
- Store it filled with paint to prevent nozzle drying
- Flush all lines with water and leave nozzles clean and dry (Correct answer)
- Apply lubricating oil to all painted surfaces
- Disassemble the unit completely after every use
Correct answer: Flush all lines with water and leave nozzles clean and dry
Flushing all lines with water after use prevents paint from drying and clogging the nozzles and lines, extending equipment life and ensuring consistent application.
Question 5: Which maintenance machine uses oscillating tines to break up surface compaction and improve air infiltration without removing soil cores?
- Solid-tine aerator (Correct answer)
- Core aerator
- Rotary tiller
- Scarifier
Correct answer: Solid-tine aerator
Solid-tine aerators penetrate the soil without removing cores, fracturing compacted layers and creating channels for air and water without the recovery time of core aeration.
Question 6: What is the correct procedure for calibrating a rotary spreader before applying fertilizer to an athletic field?
- Apply product at the manufacturer's default setting without adjustment
- Weigh the product applied over a measured test area and adjust the gate opening accordingly (Correct answer)
- Estimate coverage by the number of passes made over the field
- Use GPS data from the spreader's onboard computer to set the rate
Correct answer: Weigh the product applied over a measured test area and adjust the gate opening accordingly
Calibration requires applying product over a known test area, collecting and weighing the output, then adjusting the gate opening to match the target application rate.
