The Rise of the Case Uni-Loader Series
The Case 1835 Uni-Loader was part of a pivotal generation of skid steer loaders that helped define compact equipment in the late 20th century. Manufactured by Case Corporation, a company founded in 1842 and later merged into CNH Industrial, the Uni-Loader series was introduced to meet the growing demand for versatile, maneuverable machines in agriculture, construction, and landscaping.
The 1835 model, produced during the 1980s and early 1990s, was a mid-range unit in the lineup. It featured a robust mechanical drive system, a compact frame, and a reliable diesel engine. Though exact production numbers are hard to verify, industry estimates suggest tens of thousands of units were sold across North America, with many still in operation today.
Core Specifications and Terminology
The Case 1835 typically came equipped with:
As with many legacy machines, the 1835 presents a mix of mechanical simplicity and age-related wear. Key areas of concern include:
Operator Experience and Ergonomic Observations
The 1835’s cab is minimal by modern standards—no air conditioning, limited insulation, and basic instrumentation. Yet many operators appreciate its tactile feedback and mechanical control. The hand levers offer direct response, and the visibility from the open-frame cab is excellent for tight maneuvering.
One operator in British Columbia recalled using the 1835 to clear snow from a mountain cabin access road. Despite freezing temperatures and steep grades, the machine performed reliably, aided by its low center of gravity and chain-driven traction.
Parts Availability and Aftermarket Support
While Case no longer produces the 1835, parts remain available through:
Historical Context and Market Impact
The Uni-Loader series helped Case compete with Bobcat, New Holland, and Gehl in the compact loader market. Its success laid the foundation for later models like the 1840 and 1845C, which introduced improved hydraulics and operator comfort.
During its peak, the 1835 was a staple in rental fleets and small farms. Its simplicity made it easy to train new operators, and its durability ensured years of service with minimal downtime. Even today, it’s not uncommon to find 1835 units working in barns, feedlots, and rural construction sites.
Conclusion
The Case 1835 Uni-Loader is more than a relic—it’s a testament to mechanical reliability and design efficiency. While it lacks the electronics and comfort of modern machines, its straightforward engineering and field adaptability continue to earn respect. For those willing to maintain and upgrade, the 1835 remains a capable partner in earthmoving, material handling, and rural operations. Its legacy lives on in the hands of operators who value function over flash and durability over digital dashboards.

Core Specifications and Terminology
The Case 1835 typically came equipped with:
- Engine: A 4-cylinder diesel engine, often the Case D155 or equivalent, producing around 35–40 horsepower.
- Hydrostatic Drive: Dual hydraulic pumps powering each side independently, allowing zero-radius turns.
- Lift Capacity: Rated operating capacity of approximately 1,200 lbs (544 kg).
- Bucket Width: Standard 60-inch bucket, with optional attachments including forks, augers, and trenchers.
- Controls: Mechanical hand levers for drive and lift, with foot pedals for auxiliary functions.
- Uni-Loader: Case’s proprietary branding for its skid steer line, emphasizing single-operator versatility.
- Hydrostatic Transmission: A fluid-based drive system offering variable speed and torque without gear shifts.
- Auxiliary Hydraulics: Additional hydraulic ports used to power external attachments.
As with many legacy machines, the 1835 presents a mix of mechanical simplicity and age-related wear. Key areas of concern include:
- Hydraulic Leaks
Aging hoses and seals often develop leaks. Replacing with modern braided lines and Viton seals improves longevity.
- Drive Chain Tension
The chain-driven final drive requires periodic adjustment. Loose chains cause jerky movement and premature sprocket wear.
- Electrical System
Original wiring harnesses may degrade. Upgrading to marine-grade wiring and sealed connectors reduces shorts and improves reliability.
- Fuel Delivery
Mechanical lift pumps and injectors can clog over time. Installing a spin-on fuel filter and flushing the tank helps maintain flow.
- Cooling System
Radiators and fan belts should be inspected regularly. Overheating is common in dusty environments without proper airflow.
