ADI loppers use a steel cylinder instead of an aluminum cylinder like our competitors use. In addition, the cylinder and cylinder rod are also chrome plated and polished. This provides a very hard, smooth surface that extends the service life of the cylinder seals. The cylinder on an ADI lopper will greatly outlast the aluminum cylinders of other hydraulic tools. Despite the additional weight of the steel cylinder, the ADI loppers are still the lightest on the market.

ADI loppers come standard with a built in swivel between the handle and the cutting head. This makes penetrating a tree canopy much easier. If the cutting head must be turned, the operator is not forced to turn the handle of the tool and fight the working hoses. With an ADI tool, the operator can simply use the built in swivel to twist the cutting head. Studies have shown that most of the injuries caused from using hydraulic pruning tools occur when the operator uses the tool to flip brush out of the tree. The built in swivel on ADI loppers eliminates the operator’s ability to flip brush, lessoning the chance of injury.

We understand that there are those hydraulic pruning tool operators that have developed the ability to use the lopper to flip brush safely. We also understand that sometimes crew efficiency is dependent on this ability. With this in mind, ADI loppers can be ordered with the swivel locked in place. Also, the ability of an existing lopper to twist can be stopped by simply adding a 

locking washer.

Hardened, steel bushings are used at both ends of the linkage rod pivot points. These special bushings help to spread the load on the pivot points when cutting, ensuring long service life and minimal wear.

ADI loppers have a large diameter, chrome plated, center bolt that secures the blade to the anvil. Chrome plating allows the center bolt to maintain a hard, smooth finish that increases the longevity of the tool.
