Prevent Skid Loader Overheating When Mulching

 


Hydraulically powered attachments like mulching heads and brush cutters are very effective for converting skid loaders or compact track loaders into land management machines. These heavy duty attachments can also be abusive on the equipment and the operator. A mulching head causes the engine to work much harder than some other attachments.

Pairing the Perfect Match

It is critical when pairing a loader and attachments for land clearing applications to ensure they are not only compatible, but are also equipped to maximize machine operation and operator safety.  Be sure to select the right attachment for the job, based on the task at hand and the environment where they will be working. This will help determine which attachment is best suited for your needs.

For example, if large trees and stumps must be removed, a forestry cutter attachment and a stump grinder would be the best choice. If the primary application is clearing brush, however, a flail cutter or rotary cutter would be a good choice. Once you determine the best attachment for your loader and application, you can check with your local dealer for assistance with ensuring compatibility and optimal performance.

The most important specifications to evaluate would be the size of your track loader, the rated operating horsepower and capacity, and the available hydraulic flow to power the attachment.  Reach out to Stucchi’s hydraulic specialists with any questions about maximizing hydraulic flow with safe and efficient operation.

Standard Flow Versus High Flow Hydraulics

Standard flow hydraulics may work for light to medium jobs, although using an attachment with an underpowered machine will undoubtedly result in lessened productivity. Not only are you much less productive, you run the risk of damaging your skid loader equipment and pose safety risks to the operator. When operating a forestry mulcher, for example, not every skid steer or track loader will effectively operate the attachment.

Some forestry mulchers have the capability to handle large limbs of 8-inches or more in diameter, with a wide 5-foot cutting width.  Only a machine with high flow hydraulics will provide the horsepower needed for this attachment to get the job done correctly and safely. A skid steer with high flow hydraulics at a rate of 37 GPM with at least a 90 hp rating is the best choice for these heavier duty attachments.

Some equipment solutions may include installing a cooling system inside the head that maintains the proper temperature of the hydraulic system, while this might prevent overheating and catastrophic events that can cause, it does not necessarily help your equipment work more efficiently or with any more power.

Additional skid loader considerations include making sure the equipment can handle the weight of the attachment. This also includes considering the weight of any stabilizing counterweights required for heavy lifting.  In general, if you plan to use your skid loader for land management, clearing or mulching operations it is best to use a more powerful loader with high flow hydraulics.

Prevent Overheating and Fire with High Flow Hydraulics

Attempting to use a standard flow skid loader for heavy duty mulching applications requires a few alterations to minimize premature component wear and prevent safety concerns. Pushing a standard flow skid loader to the limit with heavy-duty land management attachments will overwork your motor resulting in overheating and can actually catch on fire. We have seen plenty of cases where this happens which poses serious safety risks to the operator, the environment and anyone in the area.

Check out this Mulching/Land Management Case Study on how Stucchi improved performance and lowered operating costs for one mulching owner / operator.

Even if your overheated machine does not catch on fire, you are still faced with downtime to let your loader cool off or be forced to operate much more slowly and less productively. Overheating and creating a fire risk can be prevented by properly equipping your skid loader with the right heavy-duty hydraulic solutions for mulching.

Stucchi’s solution with a heavier duty version of the Saturn Block and larger, 1” threaded, flat-face couplers are solving this problem for mulching operators.

The dirt and debris generated during mulching applications poses another safety risk and fire hazard, as this debris can act like a fire starter when exposed to overheated hydraulic oil. Tree sap is a unique extra hazard often seen when mulching and can build up on the rotor or the teeth and reduce the life of the bearing. It is important to keep machine coolers and air intakes clean to extend engine performance and to improve safety by minimizing the risk of fire. 

Stucchi’s Saturn Block HD Prevents Overheating When Mulching

The Saturn Block HD is a direct field replacement for many skid steer connect under pressure systems. The differentiating factor of Stucchi's Saturn Block HD vs. the Saturn Block, is that the HD features 1” VEP, threaded, flat-face couplings to support high-flow hydraulics.  The Saturn Block HD is proven to prevent the common failure of overheating when running your mulching head, thus reducing the safety risks of fire while also supporting optimal equipment performance for maximum productivity.

If your machine does not allow the installation of the Saturn Block HD, our VEP threaded flat-face coupling kit is another solution that provides the same benefits. No more waiting around for your machine to cool off or worrying about dangerous overheating, just call Stucchi for answers to all your hydraulic questions and challenges.

Preventing Contamination in Hydraulic Systems


Hydraulic oil is the lifeblood that powers hydraulic machinery and equipment used in a broad range of industry sectors around the world. Hydraulic fluid provides the pressure needed to hydraulic systems through hydraulic hoses and quick couplings at connection points. There are many reasons why contamination may occur in a hydraulic system, which could create minor disruptions or cause major equipment damage and extended downtime.

Contamination in Hydraulic Systems: The Aftermath

Preventing contamination in hydraulic systems should always be a top priority of equipment operators and maintenance technicians.  According to an article in Hydraulics & Pneumatics, 65% to 90% of all hydraulic system failures are caused by contamination as reported by industry experts. With numbers like that, preventing contamination in the first place is critically important to prevent costly consequences.

The aftermath of contamination in a hydraulic system can range in severity from causing intermittent malfunctions to expensive machinery damage with complete equipment downtime.  Hydraulic fluid contamination could cause:

 

       Costly equipment repairs

       Loss of efficiency

       System flushing

       Catastrophic failure

       Equipment downtime

 From minor inefficiencies to total equipment downtime, anytime your equipment is out of service, lost productivity negatively affects profitability. Regardless of the severity of equipment damage or failure, extensive troubleshooting is required to determine the cause of the contamination and hydraulic system failure.

What Causes Contamination in Hydraulic Systems?

There are many different possible sources of contamination in hydraulic systems. It is important to know the potential sources to deal with contamination effectively. Some of the most common causes of hydraulic fluid contamination include:

During production of hydraulic fluid - while it is rare due to strict quality controls, contamination during hydraulic fluid production can occur during mixing or processing. It is a good idea to filter all hydraulic fluid entering into a hydraulic system as even fresh hydraulic fluid could be contaminated.

Contamination during hydraulic fluid storage - of course you should always keep hydraulic fluid storage containers tightly sealed at a controlled temperature. Changes in temperature can create thermal expansion or allow moisture to access the interior of storage containers. Moisture contamination is not easy to notice visually but can significantly impact performance.

Contamination during handling and fluid transfer - anytime hydraulic fluids are exposed to the air, it is exposed to moisture, dust and airborne particles. Contamination will most definitely occur if the equipment and the area where fluid transfer is taking place are not clean. Never leave the lid off of fluid any longer than you need to and do not open fluid in an area that is not clean.

Contamination of fluid during maintenance and service - hydraulic fluid naturally degrades over time, requiring regular service intervals. Seals should be checked as leaking seals can be a source of contamination. Maintenance on hydraulic equipment provides an opportunity for many errors to allow contamination to occur. The best thing that maintenance technicians can do to prevent fluid contamination during preventive or repair maintenance procedures is to follow a meticulous checklist and always be aware of the possibility of contamination.

How to Prevent Contamination in Your Hydraulic System

All components should be thoroughly cleaned during each maintenance procedure, all hoses, hydraulic fittings and adapters should be handled carefully with a clean, lint-free cloth. Use dust caps on quick couplers and cap hoses as soon as they are opened.  Do not open new filters or seals until they are ready to be used.  Remember to always flush the system before adding fresh fluid, and always filter fluid before adding to your hydraulic system.

Flat Face Quick Couplers Limit Contamination

You can additionally reduce your risk of contamination in your hydraulic circuit by using flat-face hydraulic quick couplers, which limit contamination in any hydraulic circuit and are easy to clean.
