The Bobcat 863, a popular skid-steer loader, is known for its power and versatility. However, like many heavy machinery models, it can experience issues with its bucket controls. These controls are essential for operating the loader and managing attachments like buckets and forks. If you’re experiencing difficulties with the bucket controls, it’s important to diagnose the problem to ensure your machine functions properly. This article will explore some common issues with the Bobcat 863 bucket controls and provide troubleshooting steps.
Common Issues with Bobcat 863 Bucket Controls
To effectively troubleshoot the bucket control issues with your Bobcat 863, it’s important to approach the problem methodically. Follow these steps to identify the source of the issue:
The Bobcat 863 is a rugged and reliable machine, but like any piece of heavy equipment, it can experience issues with its bucket controls. By following a systematic diagnostic approach, you can quickly identify and resolve common problems such as unresponsive movement, erratic behavior, and sticking controls. Regular maintenance of the hydraulic system and controls will keep your machine running smoothly, improving both productivity and safety on the job site.
Common Issues with Bobcat 863 Bucket Controls
- Unresponsive Bucket Movement
- One of the most common problems is when the bucket refuses to move or responds sluggishly to control inputs. This can be a sign of issues such as:
- Hydraulic fluid problems (low levels or contamination)
- Malfunctioning hydraulic valves
- Worn-out or damaged control cables
- Faulty hydraulic cylinders
- Hydraulic fluid problems (low levels or contamination)
- One of the most common problems is when the bucket refuses to move or responds sluggishly to control inputs. This can be a sign of issues such as:
- Erratic or Inconsistent Bucket Movement
- If the bucket operates inconsistently, sometimes moving too fast or too slow, the issue might stem from:
- Air in the hydraulic system
- Damaged or worn-out hydraulic hoses
- Incorrect hydraulic fluid type or contamination
- Problems with the control valves or joystick controls
- Air in the hydraulic system
- If the bucket operates inconsistently, sometimes moving too fast or too slow, the issue might stem from:
- Sticking Controls
- If the bucket controls stick or feel stiff when operated, it can be frustrating and reduce operational efficiency. This could be caused by:
- Clogged or damaged control valve
- Deterioration of the control cables
- Lack of lubrication in the control system
- Wear and tear on the joystick or control handle
- Clogged or damaged control valve
- If the bucket controls stick or feel stiff when operated, it can be frustrating and reduce operational efficiency. This could be caused by:
- Uneven Bucket Functioning
- Sometimes, the bucket may not perform symmetrically, with one side moving slower or faster than the other. This could be due to:
- Uneven hydraulic pressure or fluid distribution
- One of the hydraulic cylinders malfunctioning or leaking
- Problems with the hydraulic lines or connections
- Uneven hydraulic pressure or fluid distribution
- Sometimes, the bucket may not perform symmetrically, with one side moving slower or faster than the other. This could be due to:
To effectively troubleshoot the bucket control issues with your Bobcat 863, it’s important to approach the problem methodically. Follow these steps to identify the source of the issue:
- Inspect Hydraulic Fluid Levels
- The first step in diagnosing any hydraulic issue is to check the hydraulic fluid levels. Low fluid levels or contaminated fluid can cause inconsistent or unresponsive bucket movement. Ensure the fluid is clean and filled to the recommended level. If the fluid appears dirty or discolored, consider flushing the system and replacing the fluid.

- Check Hydraulic Hoses and Lines
- Inspect all hydraulic hoses and lines for visible signs of wear, leaks, or cracks. Any leaks in the system can lead to pressure loss, causing the bucket to move slowly or erratically. If you find any damaged hoses or lines, they should be replaced immediately.

- Examine the Control Valves
- The control valves are responsible for directing hydraulic fluid to the bucket’s hydraulic cylinders. If the valves are malfunctioning, they may cause unresponsive or erratic movement. Inspect the control valves for any blockages, debris, or wear that might be affecting their performance. Cleaning or replacing the valves can often resolve these issues.

- Inspect Hydraulic Cylinders
- If one side of the bucket operates differently from the other, the issue may lie with the hydraulic cylinders. Look for signs of leaks, such as fluid around the seals. If a cylinder is leaking or damaged, it may need to be repaired or replaced.

- Test the Joystick or Control Handle
- The joystick or control handle that operates the bucket can become worn or stiff over time. Ensure that the control is moving freely and that no internal components are obstructing its movement. Lubricating or replacing parts of the control system may restore smooth operation.

- For Unresponsive Bucket Movement
- Top up the hydraulic fluid to the recommended levels.
- Replace any damaged hoses or cylinders.
- Ensure the hydraulic system is free of air, which can cause inconsistent movement.
- If needed, replace the control valves or clean them to restore proper fluid flow.
- Top up the hydraulic fluid to the recommended levels.
- For Erratic or Inconsistent Bucket Movement
- Check for air in the hydraulic system and bleed the lines if necessary.
- Replace or repair any worn-out or damaged hydraulic components.
- Ensure the correct hydraulic fluid type is being used and that the system is clean.
- Check for air in the hydraulic system and bleed the lines if necessary.
- For Sticking Controls
- Clean and lubricate the control valves, joystick, and control cables.
- Replace any worn-out or damaged cables or components.
- If necessary, replace the joystick or control handle to restore proper movement.
- Clean and lubricate the control valves, joystick, and control cables.
- For Uneven Bucket Functioning
- Inspect the hydraulic system for blockages or leaks.
- Ensure hydraulic cylinders are in good condition and not leaking.
- Check the fluid flow to ensure both cylinders are receiving equal pressure.
- Inspect the hydraulic system for blockages or leaks.
