Abstract
An agricultural harvester having a combine and a header is provided. The combine includes a primary hydraulic system for use in operations of the combine. The primary hydraulic system includes primary hydraulic fluid. The header is attachable to the combine and includes a header hydraulic system having a header hydraulic fluid and a heat exchanger operatively connected to the primary hydraulic system and the header hydraulic system.
Claims19
An agricultural harvester header for operative attachment to a combine, the header comprising:
- an agricultural harvester header hydraulic system having a header hydraulic fluid, and
- a heat exchanger operatively connected to the agricultural harvester header hydraulic system and configured to transfer heat between the header hydraulic fluid and another hydraulic fluid.
An agricultural harvester header attachable to a combine having a primary hydraulic system that includes a primary hydraulic fluid, the agricultural harvester header comprising:
- an agricultural harvester header hydraulic system having a header hydraulic fluid, and
- a two-fluid type heat exchanger operatively connected to the agricultural harvester header hydraulic system and configured to exchange heat with the primary hydraulic system.
An agricultural harvester header for attaching to a combine comprising a primary hydraulic system having a cooler and a primary hydraulic fluid, the agricultural harvester header comprising:
- an agricultural harvester header hydraulic system having a pump, a motor and a reservoir and forming a closed hydraulic circuit therewith, and an oil-based header hydraulic fluid independent of the primary hydraulic fluid, and
- a heat exchanger operatively connectable to the primary hydraulic system and the agricultural harvester header hydraulic system downstream the pump.
