A farmer uses a tractor with circular front wheels that are 
33
33​ inches in diameter and circular rear wheels that are 
56
56​ inches in diameter. In one day of farming, the farmer drives the tractor a total of 
14
14​ miles. How many more times did the front wheel rotate than the rear wheel on this day?

To solve the problem, we need to calculate how many times each wheel rotates during the 14-mile journey and then find the difference between the number of rotations for the front and rear wheels.

### Step 1: Convert miles to inches
First, we need to convert 14 miles into inches, since the wheel diameters are given in inches. 

There are 63,360 inches in a mile. So, 14 miles is:
\[
14 \times 63,360 = 887,040 \text{ inches}
\]

### Step 2: Calculate the circumference of each wheel
The circumference of a circle (which represents one complete rotation of the wheel) is given by the formula:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle.

- **Front wheel diameter:** 33 inches
\[
C_{\text{front}} = \pi \times 33 \approx 103.672 \text{ inches}
\]

- **Rear wheel diameter:** 56 inches
\[
C_{\text{rear}} = \pi \times 56 \approx 175.929 \text{ inches}
\]

### Step 3: Calculate the number of rotations for each wheel
To find the number of rotations, divide the total distance traveled by the circumference of each wheel:

- **Front wheel rotations:**
\[
\text{Rotations}_{\text{front}} = \frac{887,040}{103.672} \approx 8,554.39 \text{ rotations}
\]

- **Rear wheel rotations:**
\[
\text{Rotations}_{\text{rear}} = \frac{887,040}{175.929} \approx 5,042.19 \text{ rotations}
\]

### Step 4: Find the difference in rotations
Now, subtract the number of rear wheel rotations from the front wheel rotations to find the difference:

\[
\text{Difference} = 8,554.39 - 5,042.19 \approx 3,512.20
\]

Thus, the front wheel rotated approximately **3,512 more times** than the rear wheel.
