Briggs and Stratton 60 kW Fortress Standby Generator

Automatically starts in seconds when utility power is lost (Requires Automatic Transfer Switch)

When you are backing up a large home, light commercial building, or critical loads that cannot go down, a small air-cooled standby unit is not the right tool. The Briggs and Stratton 60 kW Fortress is a liquid-cooled, emergency-grade standby generator built to deliver serious, steady power with quieter operation, clean output for electronics, and the kind of warranty that actually helps you sleep at night.

This is the “lights stay on, business keeps running” solution, powered by a 5.7L V8 at 1800 RPM, configured for natural gas or propane (LP), and housed in a corrosion-resistant aluminum enclosure designed for real weather.


Why the Fortress 60 kW is the right generator when you cannot compromise

Starts automatically within seconds

The whole point of a standby generator is that you do not have to be there. With the required automatic transfer switch (ATS) installed, the system:

  • Detects utility power loss
  • Starts the generator automatically
  • Transfers the building to generator power within seconds
  • Transfers back when utility power is restored

No cords. No scrambling. No “did it start?” moments.

Liquid-cooled V8 power at 1800 RPM

At the heart of this system is a 5.7L 8-cylinder liquid-cooled engine designed to run smoother and more efficiently than high-RPM units.

What 1800 RPM gets you in the real world:

  • Better long-run durability compared to many 3600 RPM designs
  • Fuel-efficient operation for its class
  • Quieter sound profile for a high-output standby unit

Natural gas or propane configured

Connect to:

  • Your home’s natural gas line, or
  • A properly sized LP tank

That means no gasoline storage headaches and no refueling in the middle of a storm. Your runtime depends on your fuel supply and load, but the Fortress platform is built for true standby convenience.


Industry-leading warranty coverage

6-Year Parts, Labor and Travel Warranty (consumer)
This is a major differentiator. It is built to reduce the “what if it breaks and I’m on my own” worry that comes with big equipment.

Commercial warranty: 2 years.


Clean, stable power for modern electronics

Today’s homes and buildings run on sensitive electronics. This unit features a computer-friendly brushless alternator with automatic voltage regulation, giving you stable power for:

  • Network gear, modems, routers
  • Computers and office equipment
  • Security systems and controls
  • Modern HVAC boards and smart appliances

If you have a home full of electronics, power quality matters as much as wattage.


Smart controls that make ownership easier

The Briggs and Stratton AMF Controller (UL Recognized) gives you clear visibility into what the generator is doing and why.

You get:

  • Easy-to-read alpha-numeric scrolling display
  • Diagnostic monitoring and fault codes
  • Simple weekly exercise-cycle scheduling

This is the stuff that prevents surprises. If there is an issue, you see it quickly. If you want it to self-test weekly, you can set it once and move on.


Built for harsh weather and easier service

Corrosion-resistant aluminum enclosure

An aluminum enclosure helps protect the generator in extreme climates, including wet, coastal, and storm-prone areas.

Convenient service access points

Maintenance should not require unnecessary disassembly. The Fortress design includes service access points to reduce service time and hassle.

Pre-installed block heater

Cold starts are where a lot of standby systems struggle. The pre-installed block heater supports easier cold-weather starting and more consistent performance.


Turnkey extras included

This unit includes the extras you want already integrated:

  • Automatic battery charger
  • Hour meter

Less piecing together. More “installed and ready.”


Output and performance highlights

  • Rated output: 60,000 watts
  • Voltage: 120/240V single-phase
  • Frequency: 60 Hz
  • Rated amps: 250A
  • Noise level: 68 dB at 7m
  • NG power capacity: 55,000W
  • LP power capacity: 60,000W
  • Cooling: Liquid-cooled
  • Enclosure: Aluminum
  • UL listed: Yes
  • CARB compliant: Yes
  • Made in USA: Yes
  • Weight: 2020 lbs
  • Dimensions: 98" L x 39.4" W x 43" H
  • Circuit breaker size: 250A

Fuel consumption:

Natural Gas

  • 50% load: 561 ft³/hr
  • 100% load: 753 ft³/hr

Propane (LP)

  • 50% load: 7.03 gal/hr
  • 100% load: 9.56 gal/hr

These numbers matter for planning. Gas line sizing and LP tank sizing should be handled correctly during design and installation so the generator can deliver full output without fuel starvation.


Requirements and install notes (important)

  • Automatic Transfer Switch: Required, not included
  • Starting battery: Requires 775 CCA battery, not included
  • Mounting pad: Concrete pad required, not included

This is a heavy, high-output standby unit. Professional installation is the norm for safety, code compliance, and performance.


Best fit applications

The 60 kW Fortress is ideal for:

  • Large homes with substantial electrical demand
  • Light commercial buildings
  • Farms and ranches with critical infrastructure
  • Facilities that need reliable emergency-grade backup power

If you are backing up HVAC, refrigeration, well systems, security, office operations, or critical equipment, 60 kW gives you the headroom that smaller standby units cannot.


Bottom line

The Briggs and Stratton 60 kW Fortress Standby Generator is built for people who want automatic backup power with commercial-grade stability, clean output for electronics, and long-term confidence supported by an industry-leading 6-year parts, labor, and travel warranty.

If you are building a serious standby system, this is the kind of generator you install once and rely on for years.

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Great
Size: Medium, Number of Items: 1
I need something that was soft for my three year old and this ball is super great, it not only is the right size but it also fits in his mouth just right. Although he is a super aggressive chewer, the ball toy hasn't been totally destroyed yet and it is easy on his gums. The ball is so durable that got two of these toys just for fun.

The best!
UPDATE: 08/05/2025 - This is still one of my dog's 2 fav training/play toys. A couple of notes: 1. This is not a chew toy. If your pup is chewing up the rope, that's on you. That being said, you can get 100' of the poly cord rope at Home Depot for like $4.98. You can make nearly 100 ropes out of 100'. How hard is it to replace the rope????? 2. My pup is a now 15 month old Malinois. His original balls, purchase in September 2024 are still in everyday, multiple times per day, play. I did get careless and leave one where he got it and chew the rope. Easily replaced. Nothing to fret over. Yes, that was on me! 3.The foam ball is virtually indestructible! Replace the rope! 4. I noticed the price for the yellow large went from $12 each to $24. THIS will cause me to go elsewhere if they doubled in price. I LOVE these balls but not that much. I noticed they have a new yellow ball that has a strap vs. a rope. I might try that if I need one, but I have 6 of these balls, 2 never used yet, 2 that are virtually new looking, and 2 that have been in play since september 2024. I don't think I'll be buying more any time soon, but if I do need more, I hope they haven't gone up to $24 each. One of my top, go-to training tools. Quality is great other than the shrink wrap around the string joint. It's junk but not essential. Great tug and fetch toy. Essential to teaching a good "out" command (2 are recommended for this).

Best dog ball
This is our go to dog toy for our German shepherd. its great for training in sports as well as outings at the beach, considering it floats! Never had him destroy one, so its extremely durable. I like that its a bright color so its easier to locate when i accidently let go of the rope too late and end up whipping it 20 ft into the woods. Easy to clean, all around just a great toy. Also love the large size as having a dog accidently lodge a ball into its throat is a real fear of mine, I do not have to worry about that with this toy. I should also mention the rope is a must, as touching a slobbery ball isn't the greatest feeling in the world and it puts your hands out of harms way. I will forever order these.

Great ball, bad rope
Size: Medium, Number of Items: 1, Size: Medium, Number of Items: 1
My dog and I love the starmark ball on a rope tug toys. While this is one of the best tug toys we have found, I am continually disappointed with the quality of the rope. The plastic sleeve comes off the first day, and after that the stitching begins to weaken until the rope ends come apart and the rope slides out of the ball. Is there a way to improve this design so that this toy lasts longer? My dog is not left alone with the toy, it is only used as an interactive tug toy as a training reward. I am updating my review now several months later. I reinforced the rope with a paracord braid and the toy now lasts a very long time. My dog and I play with this toy everyday on our morning hike. He is a large German Shepherd with high ball drive. He carries this ball in his mouth several miles on our morning hike. We play fetch in the fields near our home and in the lake beyond the fields with this toy every day. This toy is his reward in obedience training and we play a lot of tug with it every day. Reinforcing the handle has made a huge difference as the toy lasts and lasts now with the improved rope. Great ball, we will always have a collection of them at our house!
