Power Steering, Loader Added To Old Case Tractor

Power Steering, Loader Added to Old CASE Tractor TRACTORS Loaders 15-5-10 When Washington farmer Edwin Ruff mounted a home-built front-end loader on his 1942 Case tractor he found that it steered hard so he added his own power steering system. "The added weight of the loader bucket made the tractor almost impossible to steer," says Ruff. "I already had modified the hydraulic system to operate the loader so I remodified it to add power steering." Ruff cut the steering drag link in two along the side of the tractor and mounted a two-way hydraulic valve between the two sections. He mounted a hydraulic pump in front of the tractor and a hydraulic cylinder alongside the tractor frame. The cylinder is connected to a bar that leads to the tie rod between the two front wheels. When Ruff turns the steering wheel the drag link pushes on the hydraulic valve's piston which in turn extends or retracts the hydraulic cylinder to turn the wheels. The hydraulic pump sends oil to the hydraulic valve first to operate the power steering system. Surplus oil is then used to operate the bucket. "The power steering system uses so little oil that I can use the bucket and the power steering system at the same time," notes Ruff.
