Tank Driving in Finland: Piglet and the T55

Published on June 8, 2021
Duration: 13:06

This guide details the unique driving and steering techniques for operating articulated vehicles like the Sisu Nasu and tracked vehicles such as the T-55 tank. It highlights the differences in control systems, emphasizing the need for advance input in articulated steering and the physical effort required for tracked vehicle operation. Instruction is provided by Ian McCollum, demonstrating high authority in historical military hardware.

Quick Summary

Expert Ian McCollum explains the distinct steering mechanisms of the Sisu Nasu and T-55 tank. The Nasu uses hydraulic pistons for articulated steering, while the T-55 employs steering tillers that brake individual tracks. Both require specific techniques and significant physical effort for operation.

Frequently Asked Questions

How does the Sisu Nasu vehicle steer?

The Sisu Nasu, colloquially known as the 'Piglet', steers using hydraulic pistons that pivot the connection between its front and rear articulated units, rather than traditional wheel steering.

What are the key controls for driving a T-55 tank?

Driving a T-55 tank involves a three-pedal system (gas, brake, clutch), a gear shift lever (often starting in 2nd gear), and two steering tillers that control the tracks.

What is the main difference in steering between the T-55 and a Sherman tank?

The T-55 uses hydraulic power steering tillers, while a Sherman tank employs friction-based steering. The T-55's system has a distinct engagement point, though both require significant physical effort.

What is the purpose of steering tillers on a T-55 tank?

Steering tillers on the T-55 tank act as brakes for the individual tracks. Engaging a tiller slows or stops one track, causing the tank to turn in that direction.
