II. Gerund as an Adverbial Modifier

1. After felling the trees Feller-Buncher places them in bunches.

2. In designing new model of Forwarder the designer tried to consider many things for reducing the operator fatigue.

3. In designing a unique pendulum-arm system they used combination of metals and plactics.

4. After having finished the Mechanical faculty he began to work as a logging equipment engineer.

5. The operator comfort is achieved by installing easy-to-reach controls, an adjustable seat and padded armrests.

6. By adjusting the pendulum arms the operator can level the machine while harvesting.

7. A digital monitoring system alerts the operator of potential hazards by displaying all vital machine information.

8. By lifting the cab by 1,2 m. a fixed cab riser provides the operator with a high viewing position.

9. Emissions are reduced by improving fuel combustion.

10. Without powerful diesel engine good dynamics and propulsion performance would be impossible.

11. Forwarder with large wheels can operate without disturbing the ground.

12. Engine oil, transmission and hydraulic filters can be removed without spilling.

III. Gerund as an Attribute

1. The modern supervising equipment provides the operator with the necessary information.

2. The design of the felling head provides good visibility.

3. The new turbocharged diesel engine has the high torque through the entire working cylce.

4. This machine can work effectively in sloping conditions.

5. Thinning is evenly distributed over the entire thinning area.

6. Maximum skidding performance is attained through the swing boom and grapple.

7. The thinning Forwarder Solid F9 was initially designed for thinning, but it can also be used for small-scale final felling.

8. The Forwarder has a good steering angle.

9. Parking brake is spring-applied and hydraulically-released.

IV. Gerundial Constructions

1. The cab’s having two doors offers exceptional ventilation and easy entry and exit.

2. The engine’s having the 4-stroke cycle delivers long power strokes and efficient fuel combustion with low emissions.

3. The Caterpillar’s being the world leading producer of Forest Machines is a well-known fact.

4. The saw’s pocket’s keeping stems straight is very important.

5. The boom and stick’s being mounted along the side of the cab makes them swing with the cab.

6. After the operator having repaired the machine it began to work without stops.

7. Due to his having invented the new metal alloy it became possible to make rugged, reinforced car bodies.

8. Because of the cab having a suspension design the vibration can be reduced.

9. Due to the Auto-Grab features monitoring and adjusting tong pressure loads are held while skidding.

10. I know of his working in the forest industry.

11. We heard of their having developed a new model of excavator.

12. I am not sure of the engine starting quickly in cold weather.

13. The operator insisted on the wagon being repaired.

14. We knew of their having done the selective cuts.

15. We know of Caterpiller engine oil being formulated to optimize engine life and performance.
