The Case 70XT skid steer loader is a part of Case Construction Equipment’s line of powerful and versatile machines, designed for various construction, landscaping, and agricultural tasks. However, one area of concern that some operators have raised regarding the 70XT is its auxiliary flow rate and whether the manufacturer’s stated performance claims are accurate in real-world applications. This article delves into these concerns, addresses common problems, and provides insights into how to optimize the auxiliary hydraulics for peak performance.
Overview of the Case 70XT
The Case 70XT is a popular compact track loader known for its robustness, efficient hydraulics, and reliable performance. With an operating weight of approximately 7,000 lbs (3,175 kg) and a rated operating capacity of 2,000 lbs (907 kg), the 70XT is equipped to handle demanding tasks. One of its most notable features is its auxiliary hydraulic system, which powers attachments such as augers, breakers, and trenchers.

Auxiliary Flow Rate: The Manufacturer’s Claims
One of the key selling points of the Case 70XT is its auxiliary hydraulic flow rate of 18.9 gallons per minute (GPM), which Case claims is sufficient to power a variety of attachments. According to the manufacturer’s specifications, this flow rate allows for optimal performance with attachments requiring high hydraulic power, such as hydraulic hammers, planers, and compactors.
However, some operators have expressed concerns about whether the stated flow rate is accurate in practice, particularly when it comes to high-demand applications. This leads to questions about whether Case overstated the hydraulic capabilities of the 70XT to attract potential buyers.
Real-World Auxiliary Flow Performance
While the official specs provide a baseline, real-world performance can sometimes differ. Operators working with demanding attachments often find that the auxiliary flow rate may not always meet their expectations, especially under heavy load conditions. For example, when running high-flow attachments like hydraulic breakers or large augers, the hydraulic flow may feel underpowered, leading to reduced efficiency.
Some users have reported that while the 70XT performs adequately with standard hydraulic tools, there are issues when using attachments that require sustained high-flow hydraulics. Attachments such as large snowplows or stump grinders may not perform as efficiently as they would with higher-flow systems typically found on larger, higher-rated skid steers.
Possible Causes for Reduced Flow Performance:
Operators who rely on the 70XT’s auxiliary hydraulics for high-demand applications can take a few steps to improve performance and ensure that the loader operates within its intended limits.
1. Regular Maintenance and Inspection
Proper maintenance is crucial to ensuring that the hydraulic system continues to perform at optimal levels. Here are a few tips to maintain the 70XT’s hydraulic system:
Before purchasing or using an attachment, it’s essential to check the manufacturer’s recommendations for hydraulic flow and pressure. If an attachment requires more hydraulic flow than the 70XT can provide, you may need to either use a different attachment or look into upgrading to a larger machine with a higher flow rate.
3. Use High-Flow Options When Available
Some attachments are designed to be used with high-flow auxiliary systems. If you plan on regularly using high-flow attachments, consider upgrading to a machine with a higher-rated auxiliary flow, such as a Case 570N Tractor Loader, which offers 33.5 GPM for high-flow attachments.
Alternative Solutions for High-Demand Attachments
For operators who need to run high-demand attachments with the 70XT, there are some alternatives that can help optimize hydraulic performance:
While the Case 70XT compact track loader is a robust and versatile machine with a solid auxiliary hydraulic system, its 18.9 GPM auxiliary flow rate may not be suitable for every attachment, especially those that require sustained high flow. Operators who need to use high-flow attachments regularly may find that the machine’s hydraulic system falls short of their expectations. However, with proper maintenance, understanding attachment compatibility, and considering flow rate boosters or upgrades, operators can optimize the 70XT's hydraulic performance to better meet their needs.
By paying close attention to the machine’s hydraulic system, using compatible attachments, and maintaining the loader’s hydraulic components, the Case 70XT can provide reliable and efficient performance for a variety of tasks.

Possible Causes for Reduced Flow Performance:
- Attachment Compatibility: Some hydraulic attachments are designed to work with higher flow rates than what the 70XT can provide. Using these attachments with a loader that has a lower auxiliary flow rate may result in underperformance.
- Hydraulic System Efficiency: The efficiency of a hydraulic system can decrease due to wear and tear, particularly on older machines. Low hydraulic fluid levels, dirty filters, or worn hydraulic pumps can affect the overall flow rate, leading to less power reaching the attachment.
- Pressure and Flow Adjustments: In some cases, operators may need to adjust the hydraulic pressure settings to optimize the flow rate for specific attachments. This requires an understanding of how different flow rates affect attachment performance.
- Temperature Fluctuations: Hydraulic fluids can thicken in cold weather or thin in extreme heat, which may also impact performance. Ensuring that the hydraulic system is operating at optimal temperatures can reduce performance issues.

Proper maintenance is crucial to ensuring that the hydraulic system continues to perform at optimal levels. Here are a few tips to maintain the 70XT’s hydraulic system:
- Check Fluid Levels: Always ensure that the hydraulic fluid is at the correct level, and top it off if necessary. Low fluid levels can significantly affect the auxiliary flow rate.
- Replace Hydraulic Filters Regularly: Hydraulic filters can become clogged with debris over time, which restricts flow. Regularly replacing filters will ensure that the hydraulic system remains clean and efficient.
- Inspect for Leaks: Small hydraulic leaks can add up over time, reducing the overall efficiency of the system. Check hoses, fittings, and connections for any signs of leakage.

Alternative Solutions for High-Demand Attachments
For operators who need to run high-demand attachments with the 70XT, there are some alternatives that can help optimize hydraulic performance:
- Hydraulic Flow Boosters: Hydraulic flow boosters can be added to the machine to temporarily increase the flow rate for specific attachments. These devices are particularly useful in situations where the base auxiliary flow is insufficient.
- Hydraulic Upgrades: Some aftermarket solutions allow for hydraulic upgrades, such as installing a larger hydraulic pump or adjusting the flow rate to accommodate higher demands.
