2013 John Deere 135 RTS Excavator Review: What to Expect Buying One with 3200 Hours

[MikePhua]

Introduction to the John Deere 135 RTS
The John Deere 135 RTS is a compact excavator model that has gained popularity for its balance of power, size, and versatility. The RTS stands for "Rear Two-Speed," indicating the machine’s ability to switch to a higher travel speed, useful for job sites requiring relocation. The 135 RTS typically features a 14.4 metric ton operating weight and a standard 72-inch bucket, making it suitable for a variety of construction, landscaping, and utility tasks.
When buying a used 2013 John Deere 135 RTS with around 3200 operating hours, understanding its condition, typical wear points, and maintenance history is crucial to ensuring a reliable purchase.
Engine and Performance
The 2013 John Deere 135 RTS is powered by a 4.5-liter, 4-cylinder turbocharged diesel engine. This engine delivers around 90 horsepower, providing solid digging power and smooth hydraulic response. Users have reported that the engine runs smoothly if properly maintained, with no major issues cropping up early in the machine’s life.
With 3200 hours, the engine may be approaching mid-life depending on maintenance and operating conditions. Key maintenance points to watch include:

• Regular oil and filter changes, ideally every 250 hours.
  
• Fuel system cleanliness — fuel filters should be replaced on schedule to avoid injector problems.
  
• Cooling system integrity, including radiator condition and coolant changes.
  

Owners with well-maintained 135 RTS units have reported reliable performance at 3000+ hours, but neglected machines can show signs of power loss or excessive smoke.
Hydraulic System
The John Deere 135 RTS features a robust hydraulic system with variable displacement pumps, offering smooth, precise control over boom, arm, bucket, and swing functions. At 3200 hours, hydraulic components such as:

• Pumps,
  
• Control valves,
  
• Hoses and seals,
  

may begin showing signs of wear. Leaks or spongy controls are common issues on older machines. Early detection through visual inspection and test operation is vital.
Replacing hydraulic filters and fluid at recommended intervals (typically every 1000 hours or annually) significantly extends component life. Operators praise the 135 RTS’s responsive hydraulics when in good condition, but degraded hydraulics can drastically affect performance and operator comfort.
Undercarriage Condition
The undercarriage on compact excavators like the 135 RTS is a major wear component. Tracks, rollers, idlers, and sprockets face constant abrasion, especially in abrasive soils or rocky terrain.
With 3200 hours, the undercarriage might show:

• Track wear or stretching,
  
• Worn sprockets,
  
• Roller bearing play,
  
• Potential track shoe damage.
  

John Deere’s steel tracks are generally durable but expensive to replace. Inspect track tension, look for cracked or broken shoes, and check for unusual noises during operation. Undercarriage condition is often the biggest cost factor when buying a used compact excavator.
Cab and Operator Comfort
The 2013 model comes with an enclosed cab option, featuring heating and air conditioning for operator comfort. Visibility is generally good with large windows, and controls are ergonomically laid out. After 3200 hours, cab wear signs can include:

• Worn seat cushions,
  
• Faded decals,
  
• Faulty HVAC operation,
  
• Damaged door seals.
  

A clean, comfortable cab improves productivity, so inspect for electrical system issues or broken glass.
Electrical System and Controls
Electronics on the 135 RTS control engine management, diagnostics, lighting, and instrumentation. Common electrical issues in older units include:

• Faulty wiring connections,
  
• Sensor failures,
  
• Display malfunctions.
  

Checking fault codes and test-running all systems is advisable before purchase. John Deere machines generally have reliable electronics but watch for intermittent faults or corroded connectors.
Maintenance History and Records
A well-documented maintenance log is invaluable when buying a used 135 RTS. Service intervals typically include:

• Engine oil and filter every 250 hours,
  
• Hydraulic fluid and filter every 1000 hours,
  
• Track tension adjustments regularly,
  
• Cooling system flush every 2000 hours.
  

Machines with irregular or undocumented maintenance may hide potential expensive repairs. Buyers should request records or inspect service stickers.
Common Issues and Repairs Reported
Owners of 2013 John Deere 135 RTS excavators with similar hours have commonly reported the following:

• Hydraulic leaks around control valves or cylinder seals,
  
• Track undercarriage wear requiring partial replacement,
  
• Engine injector issues when fuel quality was poor,
  
• Electrical glitches in lighting or gauge clusters,
  
• Wear in the swing bearing or boom pins after heavy use.
  

Being aware of these can prepare buyers to negotiate pricing or plan future maintenance.
Additional Features and Upgrades
Some 135 RTS models have optional attachments and features, such as:

• Quick couplers for bucket changes,
  
• Auxiliary hydraulic circuits for tools like breakers or augers,
  
• GPS or machine control systems,
  
• Rearview cameras for enhanced safety.
  

When inspecting a used unit, verify that these systems function properly if included.
Real-World Case Story
One user shared a story of buying a 2013 John Deere 135 RTS with 3200 hours that had been used primarily for utility trenching. Because the previous owner maintained it religiously and replaced the undercarriage components around 2800 hours, the buyer enjoyed trouble-free operation for over 1000 hours post-purchase. However, after 3500 hours, the hydraulic pump required replacement due to wear.
This highlights the importance of maintenance and undercarriage condition as the key determinants of lifespan and cost of ownership.
Terminology Explanation

• RTS (Rear Two-Speed): A feature allowing the excavator to travel at a higher speed for quicker repositioning on site.
  
• Undercarriage: The track system including tracks, rollers, sprockets, idlers — crucial for mobility and stability.
  
• Hydraulic Pump: Converts engine power into hydraulic pressure to move the boom, arm, bucket, and rotate the cab.
  
• Control Valves: Direct hydraulic flow to different actuators.
  
• Injector: Part of the fuel system that sprays fuel into the combustion chamber.
  
• Quick Coupler: A mechanical or hydraulic device that enables fast attachment changes without manual pin removal.
  

Summary
When considering a 2013 John Deere 135 RTS with around 3200 hours, a thorough inspection focusing on engine condition, hydraulic system integrity, undercarriage wear, and maintenance records is essential. Machines well cared for can provide many more hours of reliable service. Understanding common wear points and typical repair costs helps buyers make informed decisions.
Purchasing from a seller who provides comprehensive maintenance history and allows test operation is ideal. While not immune to wear, the 135 RTS remains a versatile and capable excavator suitable for a broad range of medium-duty earthmoving tasks.
