MECHANICAL
The Oliver 1870's 4x2 2WD chassis offers straightforward handling, making it suitable for various agricultural tasks but may struggle in uneven terrain compared to 4WD models. Its hydrostatic power steering facilitates maneuverability in tight spaces, enhancing operator comfort in open station or optional cab configurations. The advanced 18-speed three-range power shift transmission provides versatility for varying workloads, delivering seamless transitions between speeds, but the complexity may challenge less experienced operators.

OLIVER 1870 TIRES
The Oliver 1870 tractor utilizes a 10.00-16 front tire configuration and a robust 18.4-38 rear tire setup, optimizing traction and stability on diverse terrain. The larger rear tires provide enhanced load-bearing capacity and improved power transfer during heavy implement operations, making it suitable for farming tasks that require pulling force. However, operators should consider potential challenges in maneuverability due to the substantial size of the rear tires, particularly in tight spaces or uneven ground.
