Hanomag’s Industrial Heritage
Hanomag, short for Hannoversche Maschinenbau AG, was a German manufacturer with deep roots in locomotive and military vehicle production before transitioning into construction equipment in the postwar era. By the 1960s and 1970s, Hanomag had become a respected name in compact and mid-sized wheel loaders, particularly in Europe. The 22C, 33C, and 35D models represent a generation of small loaders that combined mechanical simplicity with rugged utility, often used in municipal works, agriculture, and light construction.
Model Overview and Specifications
Each of these models was designed for maneuverability and ease of maintenance, with mechanical drivetrains and minimal electronics. While exact production years vary, they were generally built between the late 1970s and early 1990s.
While some Hanomag loaders used in-house engines, many units—especially those exported or built under license—were fitted with Perkins diesel engines, such as the 4.236 or 4.248 series. These engines were widely used in agricultural and industrial equipment due to their reliability and global parts availability. In some cases, Hanomag loaders were rebadged or co-developed with Massey Ferguson, particularly in the 1980s when MF sought to expand its construction equipment line.
Hydraulics and Drivetrain Simplicity
These loaders used open-center hydraulic systems with gear pumps and mechanical control levers. The simplicity of the system made them easy to repair in the field. The drivetrains were typically mechanical with torque converters or hydrostatic drives in later models. Articulated steering was standard, offering tight turning radii.
Parts Availability and Restoration Challenges
Today, sourcing parts for these machines can be challenging but not impossible. Key strategies include:
Operational Tips for Longevity
The Hanomag 22C, 33C, and 35D loaders remain symbols of mechanical durability and straightforward engineering. Though parts and documentation may be scarce, their simplicity makes them ideal candidates for restoration and continued use in light-duty applications. With care and creativity, these machines can still move earth decades after leaving the factory floor.

These loaders used open-center hydraulic systems with gear pumps and mechanical control levers. The simplicity of the system made them easy to repair in the field. The drivetrains were typically mechanical with torque converters or hydrostatic drives in later models. Articulated steering was standard, offering tight turning radii.
Parts Availability and Restoration Challenges
Today, sourcing parts for these machines can be challenging but not impossible. Key strategies include:
- Searching for Perkins engine parts through agricultural suppliers
- Contacting European salvage yards or vintage equipment dealers
- Fabricating bushings, pins, and seals locally using original samples
- Joining vintage equipment clubs or forums for technical diagrams and manuals
Operational Tips for Longevity
- Use modern hydraulic oil with anti-wear additives to extend pump life
- Replace all rubber components if the machine has sat idle for years
- Inspect steering knuckles and articulation joints for play
- Avoid overloading the bucket, as these machines were not designed for high breakout forces
- Keep the cooling system clean, especially on Perkins-powered units prone to overheating under load
