Product Description

Werk-Brau Hydraulic Loader Coupler | ACS ISO IT JRB | 300–1,500 PSI | 10–20 GPM | For Wheel Loaders

DESCRIPTION

The Werk-Brau Hydraulic Loader Coupler is engineered for fast, secure attachment changes without requiring the operator to leave the cab. Designed to O.E.M. specifications for major loader makes and models, this heavy-duty coupler combines a high-strength steel construction, hard-chrome locking pins, and a dual-acting hydraulic cylinder for dependable attachment engagement. Its open-frame design provides excellent visibility during attachment mounting, while protective guards help shield hydraulic components from demanding jobsite conditions. Supporting 10–20 GPM hydraulic flow through a machine pilot circuit, it operates with 300 PSI minimum, 500 PSI optimal, and 1,500 PSI maximum pilot pressure. Multiple coupler styles, including ACS, ISO, IT, and JRB, support diverse loader configurations. Ideal for rental fleets, municipal operations, construction, material handling, farming, and agriculture, this loader attachment coupler helps improve equipment versatility and reduce attachment-change downtime.

Key Features

  • Fast Attachment Changes Change from one loader attachment to another quickly without leaving the cab. The hydraulic loader coupler is designed for operations where frequent attachment changes are required, helping improve workflow efficiency and reduce unnecessary operator downtime on demanding jobsites.
  • Heavy-Duty Steel Construction Built with high-strength steel throughout the coupler assembly for dependable performance in demanding loader applications. The robust construction supports frequent attachment changes across construction, agriculture, material handling, municipal, and rental fleet operations.
  • Hard-Chrome Locking Pins Hardened chrome locking pins provide enhanced resistance against wear and corrosion. This durable locking system is designed for repeated attachment engagement while helping maintain dependable coupling performance in demanding operating environments.
  • Dual-Acting Hydraulic Cylinder The hydraulic loader coupler uses a dual-acting hydraulic cylinder to provide controlled attachment engagement. This design supports secure coupling while allowing operators to change compatible attachments efficiently from inside the loader cab.
  • Open-Frame Visibility Design An open-frame construction provides improved visibility while positioning and mounting attachments. Better visibility helps operators align the coupler with attachment connection points during attachment changes, supporting efficient operation and easier equipment handling.
  • Protective Hydraulic Guards Protective guards help shield hydraulic components and fittings from exposure to harsh working conditions. The guarded configuration is suited to demanding construction, material handling, agricultural, municipal, and rental fleet applications.
  • 10–20 GPM Hydraulic Flow Designed for loader hydraulic systems requiring 10–20 GPM, making the coupler suitable for compatible machines operating within this specified hydraulic flow range. Always verify machine hydraulic specifications and coupler configuration before ordering.
  • Machine Pilot Circuit The hydraulic system is designed to operate through the machine's pilot hydraulic circuit. This configuration allows the coupler to integrate with compatible loader hydraulic systems for controlled attachment engagement and release.
  • 300 PSI Minimum Pressure Requires a minimum pilot pressure of 300 PSI for operation. Confirm the loader's hydraulic system meets the required pressure specification before installation to support proper coupler functionality.
  • 500 PSI Optimal Pressure The specified optimal pilot pressure is 500 PSI, providing a reference point for hydraulic system compatibility. Operators and equipment managers can use this specification when verifying loader hydraulic requirements.
  • 1,500 PSI Maximum Pressure The coupler has a specified maximum pilot pressure of 1,500 PSI. Staying within the specified hydraulic pressure range is important for proper system operation and component protection.
  • Multiple Coupler Styles Werk-Brau offers multiple mounting configurations, including ACS, ISO, IT, and JRB styles. Selecting the correct coupler style helps match the attachment system to the loader and supports broad fleet compatibility.
  • OEM-Engineered Compatibility Engineered to O.E.M. specifications for major loader makes and models. This approach supports accurate equipment integration while giving fleet operators a practical solution for compatible loader attachment systems.
  • Fleet Versatility Designed for rental fleets, municipal operations, construction, material handling, farming, and agriculture. One compatible coupler can help loaders handle multiple attachment types, improving equipment versatility across varied jobs.
  • U.S.-Based Manufacturing Heritage Werk-Brau is proudly based in Findlay, Ohio. The loader coupler reflects the company's focus on heavy equipment attachments and durable construction for professional loader applications and demanding working environments.

Customer photo review of Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

easy buying process and great communication. Mulcher works great, easily clears overgrown brush and even mulched a 5" thick mulberry tree fairly easily. running it off of my old 331 bobcat with no problem powering the drum at all. Only small issue which isn't a big deal is that the supplied hoses are about 16" too short to operate a full range of motion.

Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

Over all built well. I like it is all cast iron and metal and not plastic. Had to modify fertilizer disc mount to fit correctly, nothing major, a little grinding. I modified the center link hitch point to accommodate my John Deere quick hitch. Have yet to plant with it but I’m sure it will work perfect. Love the grease fittings everywhere. Reminds me of the old farm equipment I grew up on, and still use periodically.

Cole 12 MX Multiflex Planter | Model B46-664A / 0120103 | Width 13" | Size: One Row | 3PT Hitch Planter Attachment | Horsepower 25–45 HP | For Tractor

My firminator RT was delivered in good condition in ND. I will be using it next week. I have a 45 HP John Deere tractor that is supposed to lift 2000 lb but really struggles to lift this 6 foot firminator RT. I will just have to use in as a two pass operation for now. I do wish there was a better operating manual for this unit. Maybe that is something you can work on. I will give you an update once I start using it in a few days.

Put this on Kubota 900 with winch hookup. This thing is a beast (within reason). I named it ‘Homie”, cause Homie don’t play. It will take care of stuff up to about 2” in diameter. You still have to remember that this is NOT like the ones on a bobcat or larger machinery. It does have its limits. But all in all I am very satisfied with it. Now on to the good part! The staff at Ripping It are outstanding! Especially Kayla in the office. She has gone above and beyond on making sure everything went right, from ordering to questions about installation. This young lady would be of great value at ANY company ! Her knowledge and personality are like over the top. This is my first experience with Ripping It Outdoors and I can only say positive things about them. With all that being said, I do fill out reviews on things I buy, AND I give a honest review. If it’s bad then you will know it. But if it’s good, well I tell the truth ! Again Kayla, from the bottom of my heart, a great big THANK YOU for all your help and just talking to you. I feel like we’ve know each other for years!

TENT is easy to put up , material is tuff as told....only complaint is that i wish the bottom had about 3 to 4 inches overlap towards the inside so i could install a 2 x4 or something to help hold the tent down in high winds we have here in virginia thanks

Hi, my name is Ken. I’ve had a great experience with Ripping It Outdoors. I purchased a Forax Hp40 Mulcher for my mini excavator. Kayla Patterson is who I dealt with from the beginning until I received it at my house. She has been wonderful to work with and looking forward to working with her with any other orders I purchase. Kayla answered any questions I had and kept me updated throughout the whole process, can’t say it enough just a wonderful person to work with!!

Forax Ultralight Mulcher | Model HP40 | Cutting Width 40" | Carrier 2-4-Ton | For Excavators

These are great feeders if you don’t have any feral hogs but if the hogs tear off the wiring harness from the timer to the feeder motor, you’re disabled. Then, if you ask for help from Outback, they refer you to the dealer but really you’re on your own for parts and repairs. I have three Outback feeders that work as designed. They’re 13 years old and have always served well but this feeder misses the mark by a very high margin. I’d NEVER buy this product again. Feeders need to be dependable and this unit is not.
