The Rise of CTLs in Winter Work
Compact Track Loaders (CTLs) like the John Deere CT322 have become indispensable in snow removal for rural properties, commercial lots, and municipal service yards. Introduced in the early 2000s, the CT322 was part of Deere’s push to offer a mid-sized CTL with a 67-horsepower engine and a rated operating capacity of 2,200 pounds. Deere’s CTL lineup quickly gained traction—literally and figuratively—thanks to their low ground pressure and ability to operate in soft terrain.
Unlike wheeled skid steers, CTLs distribute weight across a larger footprint, making them ideal for muddy or snowy conditions. However, their rubber tracks, while excellent for flotation, often struggle with grip on icy slopes or packed snow. This has led operators to experiment with various traction-enhancing methods, especially in regions with frequent freeze-thaw cycles.
Why Rubber Tracks Slip on Snow and Ice
Rubber tracks are designed for flexibility, vibration damping, and surface protection. But in winter, these benefits become liabilities. The smooth rubber compound lacks the aggressive bite needed to grip frozen surfaces. When snow is repeatedly packed by the machine’s own weight, it turns into a slick ice layer, especially on inclines.
Key factors contributing to slippage include:

• Low friction coefficient of rubber on ice (typically <0.1)
  
• Wide track surface area reducing ground pressure
  
• Lack of tread depth or edge definition
  
• Heat from friction melting snow, then refreezing into glaze
  

• CTL (Compact Track Loader): A tracked machine used for lifting, grading, and snow removal.
  
• Grouser: Raised tread or bar on a track pad that provides traction.
  
• Track Studs: Metal inserts or bolts added to rubber tracks to improve grip on ice.
  

• Slow and Steady Movement: Avoid spinning tracks, which polishes snow into ice. Gentle throttle control preserves surface texture.
  
• Clear to the Base Layer: When possible, scrape down to gravel or pavement to avoid building up slick layers.
  
• Avoid Repeated Passes: Driving over the same path repeatedly compacts snow and reduces traction.
  
• Use the Terrain Wisely: Work perpendicular to slopes when possible. Turning into a slope increases the risk of sideways or backward sliding.
  

• Sheet Metal Screws: Coarse-thread screws inserted into track pads offer limited grip but risk tearing out and damaging tires or pavement.
  
• Bolts with Fender Washers: Drilled through the track and secured with nuts, these protrude slightly to bite into ice. Effective but must be used sparingly to avoid structural damage.
  
• Dedicated Ice Studs: Products like iGrip or MaxiGrip studs are designed for rubber tracks and offer carbide tips for durability. These are more secure and less likely to tear out than improvised screws.
  
• Polar Tracks: Bridgestone and Camso offer winter-specific track designs with cross-bar patterns that outperform block-style treads in snow. However, they are expensive (often $4,000–$5,000 per set) and wear rapidly in summer.
  

• Screws and bolts may loosen and become road hazards.
  
• Studs can damage concrete or asphalt surfaces.
  
• Modified tracks may void manufacturer warranties.
  
• Overloading tracks with hardware increases wear and vibration.
  

• Inspect tracks daily for missing hardware or damage
  
• Clean snow and ice buildup from undercarriage
  
• Monitor hydraulic fluid temperature and viscosity
  
• Use bar magnets to recover lost screws or studs
  
• Store machines indoors to prevent ice formation on controls

The Case 1830 and Its Legacy in Compact Equipment
The Case 1830 Uni-Loader was introduced in the late 1970s as part of Case Corporation’s push into the compact equipment market. With a rated operating capacity of around 1,000 pounds and a robust mechanical drive system, the 1830 quickly became a favorite among landscapers, farmers, and small contractors. Its simplicity, mechanical reliability, and ease of service made it a staple in North American fleets for over a decade.
Case Corporation, founded in 1842 in Racine, Wisconsin, had already built a reputation for durable agricultural machinery. By the time the 1830 was released, Case was expanding aggressively into construction equipment, and the Uni-Loader series helped solidify its position in the skid steer segment. Thousands of 1830 units were sold before production ended in the mid-1980s, and many remain in service today thanks to their rebuild-friendly design.
Challenges of Rebuilding Without an Engine
Acquiring a Case 1830 without an engine presents both opportunity and complexity. The machine’s mechanical simplicity makes it a good candidate for repowering, but sourcing compatible components—especially the coupler that connects the engine to the hydraulic pump—can be difficult.
The coupler is a critical part of the powertrain. It transfers rotational energy from the engine’s flywheel to the hydraulic pump, which powers all loader functions. Without the correct coupler, even a perfectly mounted engine will fail to drive the system.

The Gehl CTL 85, a compact track loader, is designed for tough jobs that require high mobility, traction, and lifting capability. However, some operators experience issues when the loader fails to reach its expected high travel speed. This problem can limit its effectiveness on large job sites, where fast movement across rough terrain is essential.
In this article, we will explore potential reasons for the low travel speed on a Gehl CTL 85, provide a detailed overview of its components, and suggest practical solutions to resolve the issue.
Understanding the Gehl CTL 85
The Gehl CTL 85 is part of Gehl’s series of compact track loaders, known for their rugged design and versatility. These loaders are equipped with an advanced hydraulic system and a reliable diesel engine to perform a wide variety of tasks, such as digging, grading, lifting, and material handling. They are particularly valuable in environments where traction is needed over softer ground, thanks to their track-based undercarriage.
The CTL 85 comes with various features, including:

• Rated Operating Capacity: 2,700 lbs
  
• Engine Power: 85 horsepower
  
• Operating Weight: Approximately 9,500 lbs
  
• Maximum Travel Speed: Around 7 mph (11.3 km/h) in high gear
  
• Hydraulic Flow: 20-25 gallons per minute (depending on model)
  

1. Hydraulic System Problems
   The CTL 85's track drive system is powered by hydraulic motors, which are controlled by the hydraulic fluid pressure. If there is a drop in hydraulic pressure or an issue with fluid flow, the motor may not operate at full capacity, thus limiting the travel speed.
   • Low Hydraulic Fluid Levels: Insufficient hydraulic fluid can prevent the motors from receiving the necessary pressure to operate at high speed.
     
   • Clogged or Dirty Hydraulic Filters: A clogged filter restricts fluid flow, reducing the performance of the hydraulic system.
     
   • Damaged or Worn Hydraulic Hoses: Leaking or damaged hoses can also lower pressure, affecting the speed.
     
   Solution:
   • Regularly check and top off hydraulic fluid levels.
     
   • Change hydraulic filters according to manufacturer recommendations.
     
   • Inspect hoses for leaks or damage and replace them as necessary.
     
2. Track Issues
   The condition of the tracks and undercarriage components can impact the travel speed. Worn-out or improperly tensioned tracks may cause unnecessary resistance, preventing the loader from achieving its maximum speed.
   • Excessive Track Tension: Too much tension can cause friction and reduce the efficiency of the track drive motors.
     
   • Worn Tracks or Sprockets: Excessively worn tracks or sprockets can also create slippage, leading to a loss of speed.
     
   • Track Misalignment: Misaligned tracks can cause uneven wear and drag, slowing down the loader.
     
   Solution:
   • Adjust track tension to the manufacturer’s recommended specifications.
     
   • Regularly inspect tracks for wear and replace them when necessary.
     
   • Check for proper alignment and make adjustments to ensure even track wear.
     
3. Transmission and Drive Motor Issues
   A problem with the transmission or drive motor can result in a significant reduction in travel speed. The drive motor is responsible for transmitting power from the engine to the tracks, so any fault here can directly affect the loader’s speed.
   • Clutch or Gear Slippage: If the clutch or gears are slipping, the machine will not transfer enough power to the tracks.
     
   • Faulty Drive Motors: A failing drive motor can reduce the overall efficiency of the machine, particularly in high-speed settings.
     
   Solution:
   • Have the transmission and drive motors checked for wear or damage.
     
   • Repair or replace damaged gears, clutches, or motors to restore proper power transfer.
     
4. Electronic and Sensor Malfunctions
   The Gehl CTL 85 uses an advanced electronic control system to manage the performance of the loader, including speed settings. Faulty sensors or wiring can cause the system to limit the loader’s speed even when mechanical components are functioning correctly.
   • Speed Control Malfunctions: The electronic speed controller may be malfunctioning, causing the loader to operate in a reduced-speed mode.
     
   • Faulty Sensors or Wiring: Issues with sensors that monitor the machine’s operational parameters, such as load or engine performance, can trigger a speed reduction.
     
   Solution:
   • Inspect all wiring and connections for signs of wear or corrosion.
     
   • Test speed sensors and control modules to ensure they are functioning correctly.
     
   • Reset or recalibrate the system if necessary.
     
5. Engine Power Issues
   A reduction in engine power can also lead to a lower travel speed. The Gehl CTL 85 is equipped with an 85-horsepower engine, and if the engine is not delivering the expected performance, it will affect all operational functions, including speed.
   • Fuel System Issues: A clogged fuel filter or malfunctioning fuel injector can restrict the amount of fuel entering the engine, reducing its power output.
     
   • Air Intake Restrictions: A dirty or clogged air filter can starve the engine of air, leading to a loss of power.
     
   • Exhaust Restrictions: A clogged exhaust system can reduce the engine’s ability to expel gases, affecting performance.
     
   Solution:
   • Clean or replace the fuel filter and air filter regularly.
     
   • Inspect the exhaust system for blockages and clear them as needed.
     
   • Ensure the engine is receiving proper fuel pressure and air flow.
