The LX885 and Its Hydraulic System Design
The New Holland LX885 skid steer loader, produced in the mid-1990s, was part of a highly successful lineup that helped define the brand’s reputation for reliability and performance in compact equipment. With a rated operating capacity of approximately 2,500 lbs and powered by a four-cylinder diesel engine, the LX885 features a closed-center hydraulic system that powers both the loader arms and auxiliary attachments. The system includes a hydraulic reservoir, suction and return filters, and a tandem gear pump driven directly from the engine.
Hydraulic fluid in this system is not only responsible for powering implements but also for lubricating internal components and dissipating heat. Any contamination—especially water—can compromise performance, corrode internal parts, and in cold climates, lead to catastrophic freeze-ups.
Recurring Freeze-Up and Water Intrusion Symptoms
One long-term LX885 owner reported that since 2019, the machine’s hydraulics would freeze each winter, requiring a full system drain and filter replacement annually. Despite limited seasonal use and careful maintenance, water continued to infiltrate the hydraulic fluid, leading to:
Common Sources of Water Contamination
Water can enter a hydraulic system through several pathways:
To mitigate water intrusion and prevent winter freeze-ups:
Long-Term Maintenance Strategy
If water contamination has been a recurring issue for multiple seasons, it may be necessary to:
Conclusion
Water in the hydraulic system of a New Holland LX885 is more than a seasonal nuisance—it’s a threat to system integrity and machine reliability. By identifying the source of moisture, upgrading breather and storage practices, and using cold-weather-rated fluids, operators can prevent freeze-related failures and extend the life of their equipment. The LX885 remains a capable and durable machine, but like any hydraulic system, it demands vigilance when winter sets in.

Recurring Freeze-Up and Water Intrusion Symptoms
One long-term LX885 owner reported that since 2019, the machine’s hydraulics would freeze each winter, requiring a full system drain and filter replacement annually. Despite limited seasonal use and careful maintenance, water continued to infiltrate the hydraulic fluid, leading to:
- Sluggish or completely inoperative hydraulics in sub-freezing temperatures
- Milky or foamy fluid appearance, indicating emulsified water
- Ice formation in lines and valves, risking pump cavitation or seal rupture
Common Sources of Water Contamination
Water can enter a hydraulic system through several pathways:
- Breather cap failure: If the reservoir breather is damaged or missing its desiccant element, humid air can condense inside the tank during temperature swings.
- Condensation from infrequent use: Machines that sit idle for long periods, especially outdoors, accumulate moisture internally as warm daytime air cools overnight.
- Worn cylinder seals: External water can be drawn into the system through deteriorated rod seals, especially during snow removal or wet operation.
- Improper fluid storage: Using hydraulic fluid stored in open or unsealed containers can introduce moisture before it even enters the machine.
To mitigate water intrusion and prevent winter freeze-ups:
- Replace the hydraulic reservoir breather with a sealed, desiccant-style breather to block humidity
- Install a tank heater or hydraulic fluid preheater for cold starts
- Use premium hydraulic fluid with water separation additives and low pour point ratings
- Drain and flush the system thoroughly, including hoses, cylinders, and control valves
- Store the machine indoors or under cover when not in use
- Operate the loader periodically during the off-season to circulate and warm the fluid
Long-Term Maintenance Strategy
If water contamination has been a recurring issue for multiple seasons, it may be necessary to:
- Replace all hydraulic filters, including suction and return elements
- Inspect and clean the reservoir interior for sludge or rust
- Pressure test cylinder seals and valve blocks for internal leakage
- Install a fluid sampling port to monitor water content annually
