Power steering on the Ursus C-330 is one of the most popular upgrades that significantly improves the driving comfort of the tractor. The factory steering system is heavy to operate, especially when working with a front loader or on rough terrain.
There are currently two main types of power steering available:
Hydraulic – which is divided into systems with an actuator mounted along the engine and laterally between the steering knuckles. In addition, there are different ways to drive the pump – from the valve train, a V-belt, or directly through the driveshaft.
Electric – which uses an electric actuator mounted transversely. This type of power steering is becoming increasingly popular, especially among those looking for a simpler and cheaper solution. Electric power steering does not require interference with the tractor’s hydraulic system, which makes it easier to install.
Each of these solutions has its own advantages and disadvantages, so it’s worth carefully analyzing which will work best in your case.
Types of hydraulic power steering
1. power steering with the actuator along the engine
In this system, the hydraulic cylinder is mounted longitudinally to the axle of the tractor, usually on the left side of the engine.
Advantages:
Theoretically provides good wheel control and steering precision.
A proven and used design in various models.
Disadvantages:
Often causes excessive stress on the left steering knuckle, leading to faster wear.
There is a risk of damage to the pins, mountings and pulling the beam out of the bracket.
In practice, users often complain of rapid wear of steering components.
2. power steering with the actuator across.
In this solution, the hydraulic actuator is mounted transversely between the steering knuckles.
Advantages:
Durable and reliable solution that does not put excessive strain on one side of the steering system.
Good handling characteristics and turning stability.
Relatively simple installation and no need for axle reinforcement.
Disadvantages:
May require minor modifications for non-standard models.
Ways to drive a hydraulic pump
Hydraulic power steering can be driven in several ways:
Pump on the valve train – the most recommended solution, independent of PTO operation, providing constant pressure.
Pump on the drive shaft – can work well, but with heavier loads can cause performance drops.
V-belt pump – a less common solution, used on some models, but less durable than a timing belt pump.
Electric power steering
Electric power steering works on the principle of an electric actuator mounted transversely between the steering knuckles.
Advantages:
Quiet operation – no noise from the hydraulic pump.
Easier installation than hydraulic systems.
Lower purchase cost compared to hydraulic power steering systems.
Disadvantages:
More susceptible to wear – after a year of intensive use, backlash may appear.
Less durability compared to hydraulics, especially when working with a loader.
Dependence on the electrical system – if the tractor’s power fails, the system stops working.
Which solution to choose?
If the tractor is used for front loader work or in difficult terrain, the best choice will be hydraulic power steering with a cylinder across and a pump on the valve train. This is the most durable and reliable solution.
For those looking for a cheaper and easier-to-install solution, electric power steering can be a good option, but be aware that it wears out faster with heavy use.
In contrast, power steering with an actuator along has significant drawbacks and is less recommended due to the risk of damage to the steering system.
What’s Included in the Power Steering for the C360?
The C360 tractor is one of the most important implements on Polish farms and has been highly regarded for its durability and reliability for years. However, as with many older machines, steering a tractor without a power steering system can be a challenge, especially when the tractor is operating with additional loads, such as a […]
