Fitting Pallet Forks to a Case 1835C Skid Steer Without a Quick Attach System

[MikePhua]

The Case 1835C and Its Attachment Legacy
The Case 1835C skid steer was introduced in the late 1980s as part of Case’s compact equipment lineup. With a rated operating capacity of around 1,300 pounds and a 50-horsepower diesel engine, it became a popular choice for landscapers, farmers, and small contractors. Unlike modern skid steers equipped with universal quick attach systems, the 1835C used a proprietary pin-on bucket mounting system, which complicates the installation of aftermarket attachments like pallet forks.
Case Construction Equipment, founded in 1842, has a long history of innovation in agricultural and construction machinery. The 1835C was part of a transitional era before standardized quick couplers became industry norm. As a result, owners today often face challenges when retrofitting modern tools to older machines.
Understanding the Pin-On Mounting System
The original bucket on the 1835C is mounted using a pair of vertical pins that secure the attachment to the loader arms. This system lacks the flat-faced quick coupler found on newer machines, which allows attachments to be swapped in seconds. Instead, any new attachment must either replicate the pin-on geometry or be adapted using a custom interface plate.
Terminology:

• Quick attach: A standardized mounting system using levers or hydraulics to lock attachments in place
  
• Pin-on: A fixed mounting system using steel pins inserted through brackets on the loader arms
  
• Interface plate: A fabricated steel adapter that allows non-standard attachments to connect to a machine
  

Options for Adding Pallet Forks
Owners of the 1835C have two main options when adding pallet forks:

1. Fabricate a custom mounting plate that mimics the original bucket’s pin-on geometry
   
2. Purchase a universal pallet fork frame and weld it to a plate that fits the loader arms
   

Fabrication requires precise measurement of the bucket’s mounting points, including:

• Pin diameter and spacing
  
• Vertical and horizontal offset from the loader arms
  
• Tilt angle and clearance for hydraulic cylinders
  

One operator successfully built a plate using ½-inch steel with gussets and reinforcements, then welded a standard fork frame to the front. The result was a rigid, functional attachment that could be removed with basic tools.
Sourcing Fork Frames and Components
Pallet fork frames are widely available from agricultural and construction suppliers. Most are designed for quick attach systems, but the fork carriage and tines can be repurposed. When selecting a frame, consider:

• Width: 42 to 48 inches is typical for compact skid steers
  
• Fork length: 36 to 48 inches depending on load type
  
• Capacity: Minimum 2,000 pounds to match the 1835C’s lift rating
  
• Backrest height: Higher backrests improve load stability
  

Some manufacturers offer blank backplates that can be drilled or welded to match older machines. Salvage yards may also carry used fork frames from retired equipment.
Safety and Structural Considerations
When fabricating or modifying attachments, structural integrity is paramount. Pallet forks are subject to high bending forces, especially when lifting uneven loads or operating on slopes.
Recommendations:

• Use grade 50 or higher steel for mounting plates
  
• Reinforce welds with gussets at stress points
  
• Test the attachment with light loads before full operation
  
• Inspect pins and brackets for wear or deformation
  

One technician recalled a homemade fork frame that failed under load due to thin steel and poor weld penetration. The incident damaged the loader arms and required costly repairs.
Alternative Solutions and Retrofit Kits
Some aftermarket suppliers offer retrofit quick attach kits for older Case skid steers. These kits replace the pin-on brackets with a universal coupler, allowing use of modern attachments. While more expensive, they offer long-term flexibility and resale value.
Benefits of retrofit kits:

• Compatibility with hundreds of attachments
  
• Faster swap time between tools
  
• Improved safety and operator convenience
  

Installation typically involves removing the original bucket brackets and bolting or welding the new coupler in place. Kits range from $600 to $1,200 depending on model and supplier.
Conclusion
Adding pallet forks to a Case 1835C requires creativity, fabrication skills, and attention to detail. Whether building a custom plate or investing in a retrofit coupler, the goal is to create a safe, functional interface that respects the machine’s original geometry. With proper planning and quality materials, even a vintage skid steer can be equipped for modern tasks. In the world of compact equipment, adaptability is the true measure of utility.
