Key Features and Specifications
The 3500 Series A was equipped with features that were considered advanced for its time. Here’s an overview of some key specifications:
- Engine and Power
The International Harvester 3500 Series A loader is powered by a gasoline or diesel engine, depending on the model. Its engine typically offers a power output between 55 to 70 horsepower, making it suitable for a variety of medium-duty tasks. The choice between gasoline and diesel depends on fuel economy preferences and the power demands of the specific application.
- Operating Capacity
The 3500 Series A has a lifting capacity of approximately 2,000 to 2,500 pounds, which is appropriate for tasks such as moving bulk materials, lifting equipment, and even light digging.
- Transmission and Drive System
The loader features a hydrostatic drive system, which allows for smooth and efficient power transfer. This system was relatively advanced at the time, providing easy maneuverability and less wear on mechanical parts. The hydrostatic transmission provides variable speed control, which is crucial for precise handling in tight spaces.
- Loader Arm and Attachment Compatibility
The loader arms of the 3500 Series A are designed for durability and ease of use. The loader arms can handle a range of attachments such as buckets, forks, and even pallet jacks, making the loader versatile for different types of jobs. The lift arms are hydraulically powered, and the system is designed to work well in both lifting and digging tasks.
- Cab and Operator Comfort
The cab in the 3500 Series A is designed with basic features intended to provide comfort and safety to the operator. While not as advanced as modern equipment cabs, the layout offers straightforward controls and sufficient visibility to perform tasks effectively. The ergonomic design ensures that operators can work for extended hours with minimal discomfort.
