The Bobcat 763 skid steer is a powerful and reliable machine known for its versatility and durability. However, like all heavy equipment, it can experience mechanical issues over time. One common issue reported by operators is a sticky float pedal—a problem that can impede smooth operation and hinder productivity.
The float pedal is an essential part of the Bobcat 763, allowing the operator to disengage the hydraulic system so that the machine can float over the surface. This function is especially useful for tasks like grading, leveling, and smoothing surfaces. When the pedal becomes sticky or unresponsive, it can cause difficulties in maintaining proper control and affect the overall performance of the skid steer.
In this article, we’ll dive into the causes of a sticky float pedal, how to fix it, and preventive measures to avoid this issue in the future. We'll also include real-world experiences to help you troubleshoot and fix the problem quickly.
Understanding the Float Pedal Mechanism
Before addressing the sticky float pedal issue, it’s important to understand how the system works. The float function on the Bobcat 763 skid steer uses a hydraulic circuit to allow the lift arms and attachment to move independently of the hydraulic system, which can be useful for tasks like snow removal or earth moving.
When you engage the float pedal, it disengages the hydraulic pressure from the lift system, allowing the bucket or attachment to float on the ground. However, for this to work smoothly, the pedal must return to its neutral position without any resistance. A sticky or stuck float pedal means that the hydraulic system is either not disengaging properly or the pedal itself is not returning to its neutral position.
Common Causes of a Sticky Float Pedal
A sticky float pedal can result from a number of issues, including mechanical wear, contamination, or issues with the hydraulic system. Below are the most common causes:
Fixing a sticky float pedal requires careful diagnosis and a methodical approach. Here’s a step-by-step guide to troubleshoot and resolve the issue:
A contractor in Nevada shared their experience with a sticky float pedal on their Bobcat 763 while working on a landscaping project. They initially noticed that the float pedal was becoming increasingly sluggish and didn’t fully disengage the hydraulic system, making grading difficult.
After cleaning the pedal area and checking the fluid levels, they found that the problem was caused by a clogged hydraulic valve. The valve had accumulated debris, which restricted fluid flow and prevented the float pedal from functioning correctly. Once they cleaned the valve, the float pedal returned to normal operation, allowing them to continue their work efficiently.
This story highlights the importance of regular maintenance and attention to the hydraulic system to avoid issues with the float pedal and other vital functions.
Preventing Future Float Pedal Issues
To prevent the float pedal from becoming sticky in the future, follow these preventive measures:
A sticky float pedal on the Bobcat 763 is a common issue, but with the right troubleshooting steps and regular maintenance, it can be easily fixed. By inspecting the pedal mechanism, hydraulic system, and related components, you can restore the smooth operation of the float pedal and ensure that your machine continues to perform optimally.
Remember, regular cleaning, proper fluid maintenance, and timely repairs are key to preventing issues like this from disrupting your work. Keeping your Bobcat 763 in top shape will not only improve its performance but also extend its lifespan, helping you tackle projects with greater efficiency.

Common Causes of a Sticky Float Pedal
A sticky float pedal can result from a number of issues, including mechanical wear, contamination, or issues with the hydraulic system. Below are the most common causes:
- Dirt and Debris in the Pedal Mechanism: Over time, dirt, dust, and debris can accumulate around the pedal mechanism, causing it to become sluggish or sticky. This is especially common in dusty job sites where the skid steer is regularly exposed to dirt and grime.
- Worn or Damaged Pedal Linkage: The pedal linkage connects the float pedal to the hydraulic control system. If the linkage is worn out or damaged, it may not engage or disengage properly, causing the pedal to stick.
- Hydraulic Fluid Issues: The hydraulic system plays a critical role in the float function. Low hydraulic fluid levels or contaminated hydraulic fluid can cause sluggish pedal operation or failure to disengage the float.
- Faulty Float Pedal Return Spring: The return spring is responsible for bringing the float pedal back to its neutral position after being depressed. If the spring becomes weak or breaks, the pedal may not return smoothly, causing it to feel sticky or unresponsive.
- Hydraulic Valve Problems: The float function is controlled by a hydraulic valve that diverts the hydraulic flow. If this valve becomes faulty or blocked, it can prevent the float pedal from engaging or disengaging correctly.
Fixing a sticky float pedal requires careful diagnosis and a methodical approach. Here’s a step-by-step guide to troubleshoot and resolve the issue:
- Inspect the Pedal Mechanism: Start by cleaning the area around the float pedal. Use compressed air to blow out any dirt or debris from the pedal mechanism and linkage. Check for any visible signs of wear or damage in the pedal or linkage. If the pedal is physically sticking, lubricating the mechanism with a silicone-based lubricant may help restore smooth operation.
- Check the Pedal Linkage: Inspect the linkage connecting the float pedal to the hydraulic control system. Look for any signs of damage or wear. If the linkage is bent or broken, it will need to be replaced. Make sure the linkage is properly adjusted to ensure smooth operation.
- Inspect Hydraulic Fluid Levels and Condition: Check the hydraulic fluid levels to ensure they are at the proper level. Low hydraulic fluid can cause the system to malfunction, including the float function. If the fluid is dirty or contaminated, drain and replace it with the manufacturer-recommended fluid.
- Examine the Return Spring: If the float pedal isn’t returning smoothly, it could be due to a faulty return spring. Check the spring for any signs of wear or damage. If the spring is weak or broken, it will need to be replaced. Ensure the spring is properly installed and is capable of returning the pedal to its neutral position.
- Check the Hydraulic Valve: The float function is controlled by a specific hydraulic valve. If this valve is clogged or damaged, it could cause issues with the float pedal. Consult the machine’s service manual to locate the valve and inspect it for any blockages or leaks. If the valve is malfunctioning, it may need to be cleaned or replaced.
- Test the Float Pedal: After performing these checks and repairs, test the float pedal by operating the skid steer. Engage and disengage the float function multiple times to ensure the pedal moves smoothly and the machine performs as expected. If the pedal is still sticking, recheck the linkage, fluid, and return spring for any additional issues.

Preventing Future Float Pedal Issues
To prevent the float pedal from becoming sticky in the future, follow these preventive measures:
- Regular Cleaning: Make sure to clean the pedal area frequently, especially if you’re working in dusty or muddy conditions. Keeping the mechanism free of dirt and debris will help maintain smooth pedal operation.
- Check Hydraulic Fluid Regularly: Keep an eye on the hydraulic fluid levels and change the fluid regularly to avoid contamination and ensure smooth operation. Follow the manufacturer's maintenance schedule for fluid replacement.
- Lubricate the Pedal Linkage: Periodically lubricate the pedal linkage with a silicone-based lubricant to prevent rusting and wear. This will help the pedal return smoothly after each use.
- Inspect Components for Wear: Regularly check the return spring, linkage, and hydraulic valves for any signs of wear. Replacing worn components early can prevent more serious issues from developing.
