Chopper blades will be mounted on chopper drums in the same manner as originally mounted by the manufacturer, that is, with the beveled side of the blade toward the front of the chopper when the blade is in contact with the ground. The Refuge Officer may order the removal and require replacement of any unsatisfactory equipment.

The contractor will furnish sufficient personnel and equipment to treat an average of 15 acres per working day.

Single Drum Chopping Woody Brush

This job consists of Single Drum chopping designated acres in the project area. The sites are in a variety of conditions. Most areas are fairly open. Ground conditions are generally mesic/wet flatwoods, but there are some wetter areas including areas adjacent to wetlands.

The purpose of this project is to reduce shrub competition, create a fuel bed for prescribed burning, and prepare the site for groundcover restoration.

In addition to all the above requirements, the following requirements apply:

1. All brush, trees and dead woody debris up to 4” in diameter measured 4-1/2 feet above ground will be chopped, unless otherwise designated by the Refuge Officer.

Living pine trees and snags larger than 4” diameter at breast height and taller than 10 feet will be left standing.

2. Chopper drums must have a minimum diameter of 40”, a width of 10 ft. (Drum dimensions do not include the frame or blades). The minimum acceptable blade length is 8 inches. The cutting edge of the blades must be kept sharp and must not exceed 1/4 inch in thickness. Broken blades will be replaced within 48 hours. The chopper unit shall be no wider than 12 feet (including frame) unless approved by the Refuge officer.

3. The drums must be filled with enough water to maintain a minimum weight to cut all woody material less than 2” diameter all the way through. No limbs/ tops or branches may be left more than 1 ft tall. This may require more than one pass of the chopper.

4. The chopper will need to be pulled with a crawler or rubber tired tractor with sufficient power to work at an average speed of at least 3 miles per hour. Swamp crossings, and parts of some stands can be wet. Low ground pressure equipment is required.

5. Each row of chopping shall overlap the preceding row by a minimum of 10% of the drum width. It will be acceptable to leave a buffer of up to 3 ft. around any leave trees or standing snags

6. Tractors must minimize soil disturbance and rutting. Turning areas and swamp crossings must be kept to a minimum. Rutting in the stands will not be acceptable.

Low ground pressure equipment is required. No heavy equipment will be allowed to operate within the treatment units sooner than 48 hours after a rain event of 2 inches or more.

7. Refuge officer may order a change in the configuration or off-set of the drum to achieve desired results. Changes in equipment configuration shall not affect the contract price for that area.

8. Contractor shall not damage pine trees > 4” in diameter measured 4-1/2 feet above ground.

Personnel Requirements - Contractor shall be responsible for providing the proper personal protective equipment for his/herself and crew.

Erosion Control - The Contractor's operation will be conducted to avoid unnecessary soil erosion. He will install and/or maintain drainage dips and water bars on skid trails and roads where designated by the Refuge Officer.
