Optimizing Auxiliary Hydraulics on the Kubota SVL-95-2S Compact Track Loader
#1
Model Background and Significance
Kubota, a Japanese manufacturer established in 1890, has long been known for its durable equipment. In recent years, Kubota’s compact track loader line has gained traction in construction, agriculture, and landscape sectors. The SVL-95-2S, introduced in 2022, is a mid-size model offering ~92 horsepower, premium operator ergonomics, and an enhanced auxiliary hydraulic system. It’s positioned between the more compact SVL-75 and the larger SVL-125, making it a versatile choice for mixed-application job sites. Sales figures place the SVL-95-2S among Kubota’s top-selling loaders in North America since launch, especially valued for its hydraulic capabilities.
Auxiliary Hydraulic System Explained
The SVL-95-2S comes standard with auxiliary hydraulics delivering 13 gpm at 3,000 psi—capable of driving a wide range of attachments like augers, mulchers, cold planers, and hydraulic breakers. Key system components include:
  • Gear pump supplying auxiliary circuit; visible in rear hydraulic module
  • Control valve manifold with dedicated left/right switch and flow control knob for precision
  • Detachable high-flow couplers, mounted low and accessible from the operator station
Common Questions and Solutions
Attachment doesn’t move or only pulses: Often caused by stuck couplers or trapped air. Solution: clean coupler faces, cycle open/close, bleed lines by slightly loosening a connected line with engine idling until fluid is steady.
Flow is too fast or too slow: The flow control knob on the joystick allows adjusting flow down from 13 gpm to roughly 5 gpm for small attachments or feathering.
Hydraulic oil overheats after prolonged use: The SVL-95-2S features a hydraulic cooler. Overheating usually comes from blocked fins. Solution: clean the cooler core aggressively with compressed air or low-pressure power washer while avoiding fins damage.
Hoses too short or lacking quick disconnect: Common on aftermarket attachments. Solution: use OEM length hoses from Kubota extended-length kit (approx. 8 ft) which maintain minimum bend radius and fit the quick coupler block.
Performance Specifications
  • Engine: Kubota V3307-CR-TE5B, 3.3 L, 92 hp @ 2,400 rpm
  • Operating weight: ≈8,600 lb (3,900 kg)
  • Auxiliary flow: 13 gpm (49 L/min), 3,000 psi
  • Drive system: Dual hydrostatic pumps for tracks providing 7 mph travel
  • Controls: Pilot joystick with auxiliary flow knob and detents
Real-World Insight
A landscaping contractor in Vermont reported that adding a brushcutter to the SVL-95-2S cut his clearing time in half. However, the initial setup ran the hydraulic oil temp to 260 °F within ten minutes on a hot day. He cleaned the cooler and re-routed hoses away from the exhaust, dropping the final oil temp to around 210 °F—well within operational tolerance and avoiding the shutdown warning.
Maintenance Tips and Best Practices
  • Daily: Wipe couplers, verify there’s no water or debris in hydraulic reservoir sight glass
  • 50-hour interval: Check cooler fins for debris, test auxiliary valve operation
  • 250-hour service: Replace hydraulic filter and inspect hoses for swelling or abrasion
  • Prevent flow loss: If auxiliary pressure drop is noticed, check for clogged filters or leaking attachments before suspecting pump issues
Summary: Why It Matters
The SVL-95-2S auxiliary hydraulics deliver substantial power in a compact package, making it equally suited to mulching, augering, snow-clearing, or trenching. Understanding its 13 gpm / 3,000 psi hydraulic system—and how to maintain couplers, coolers, valves, and hoses—ensures maximum uptime and early problem detection. Kubota's dealer network and parts availability further enhance long-term serviceability.
Key Details Recap
  • 13 gpm @ 3,000 psi auxiliary circuit with adjustable flow knob
  • Gear pump, joystick control valve, quick-disconnect coupler block
  • Hydraulic cooler near rear; requires cleaning for heat management
  • Daily and periodic maintenance keeps performance strong
  • Built on the reliable SVL-95-2S platform: ~92 hp, ~8,600 lb, great visibility and comfort
The Kubota SVL-95-2S stands out for operators needing serious hydraulic capability in a nimble loader—particularly when paired with the right preventive maintenance, it’s a reliable work partner across seasons.
