EETC - Equipment & Engine Training Council Reel Technology and Setup Questions and Answers

Question 1

A technician observes a distinct 'washboard' or 'marcelling' pattern on a turf surface after mowing.
This issue is most commonly caused by the relationship between the height of cut (HOC) and which other operational setting?

Accepted Answer

Frequency of clip (FOC) being greater than the HOC

Answer

Bedknife to reel contact being too tight

Answer

An incorrect bedknife attitude

Answer

Front roller bearings being worn or loose

Question 2

What is the primary purpose of applying an abrasive backlapping compound to a reel and bedknife assembly?

Accepted Answer

To hone and mate the cutting edges of the reel and bedknife

Answer

To establish a relief angle on the reel blades

Answer

To remove large nicks and damage from the bedknife

Answer

To set the initial reel-to-bedknife clearance

Question 3

A technician is performing a 'relief grind' on a cutting reel. Which of the following best describes the goal of this procedure?

Accepted Answer

To reduce the contact area of the trailing edge of the reel blade

Answer

To make the reel perfectly cylindrical and concentric

Answer

To apply a hardened coating to the cutting edge

Answer

To sharpen only the bedknife by using the reel as a guide

Question 4

When performing a bench setting for the Height of Cut (HOC) on a reel mower, the measurement should be taken from a flat surface plate to the:

Accepted Answer

Top front edge of the bedknife

Answer

Centerline of the front roller

Answer

Lowest point of the reel blades

Answer

Bottom of the rear roller

Question 5

A technician is setting the reel-to-bedknife adjustment. After achieving a clean cut on a single sheet of paper across the full width of the reel, they notice the reel is very difficult to turn by hand and makes a heavy grinding sound. What is the most likely issue?

Accepted Answer

The reel-to-bedknife contact is too tight.

Answer

The backlapping compound was not fully cleaned off.

Answer

The reel bearings are failing.

Answer

The bedknife attitude is too aggressive.

Question 6

The term 'Frequency of Clip' (FOC) is calculated using which three variables?

Accepted Answer

Reel speed (RPM), number of blades, and ground speed

Answer

Reel diameter, number of blades, and engine RPM

Answer

Ground speed, height of cut, and reel speed (RPM)

Answer

Number of blades, bedknife angle, and reel diameter
