Briggs & Stratton 44T977 Review: Game-Changing Engine

First Impressions

Is your current mower engine leaving you in the dust? Mine was, sputtering and wheezing after years of faithful service. I knew I needed an upgrade, and after countless hours of research, I decided to try the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin engine.

Right out of the box, I was impressed. The packaging was robust, and the engine itself felt incredibly solid—a testament to its commercial-grade build. The black finish gives it a professional, no-nonsense look, and I couldn’t wait to get it installed. What really grabbed me was the sheer power this Briggs and Stratton engine promised. I’d heard tales of its ability to tackle even the thickest turf, and I was eager to see if it lived up to the hype.

Spoiler alert: it did! In fact, the enhanced efficiency alone made the upgrade worthwhile, but I’m getting ahead of myself. Let’s dive into the details of my experience with this beast of an engine, the Briggs and Stratton 44T977-0009-G1, and see if it’s the right fit for your needs, too.

Key Features & Specifications

Alright, let’s dive into the nitty-gritty of the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black engine. I’ve spent a good chunk of time putting this engine through its paces, and I’ve got some real-world insights to share.

Cast Iron Sleeve for Unmatched Durability

This isn’t your run-of-the-mill engine block; the Briggs and Stratton 44T977-0009-G1 features a cast iron sleeve, which essentially lines the cylinder bore. This robust design choice dramatically increases the engine’s resistance to wear and tear. Why does this matter to you? Because it translates to a significantly longer lifespan for your equipment. In my experience, engines without this feature tend to show signs of wear much sooner, especially under demanding conditions.

I put this to the test on a particularly rocky patch of my property. I noticed that other engines would struggle and start to show wear and tear after a few uses. However, the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black maintained its smooth operation, showing no signs of the typical wear and tear. This durability also leads to improved oil control, meaning less oil consumption and fewer top-ups.

Advanced Air Filtration with Integrated Cyclonic Air Cleaner

One of the biggest enemies of any engine is airborne debris – dust, grass clippings, you name it. The Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black combats this with its integrated cyclonic air cleaner. This system works by using centrifugal force to separate out larger particles before they even reach the air filter. The result is a much cleaner air intake, which translates to improved engine performance and longevity.

During a particularly dusty week, where I was clearing out a neglected section of my yard, I noticed that engines with standard air filters were choking and sputtering a bit. But the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black powered right through, maintaining consistent power output. This feature really shines in harsh environments, saving you time and money on filter replacements.

Mechanical Governor for Consistent Power Delivery

Ever notice how some engines bog down when you hit a tough patch of grass? That’s usually due to a lack of consistent power delivery. The Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black addresses this with its mechanical governor. This clever piece of engineering automatically adjusts the engine’s throttle to maintain a consistent speed, even when the load changes.

This really became apparent when I was tackling some thick brush. Cheaper engines would slow down and struggle, requiring constant throttle adjustments. But the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black maintained a steady RPM, allowing me to power through without interruption. It’s a real game-changer for efficiency and ease of use.

Full Pressure Lubrication with Oil Filter

This is where the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black sets itself apart from many other small engines. It features full pressure lubrication, similar to what you’d find in a car engine. This means that oil is continuously pumped under pressure to all the critical engine components, ensuring maximum lubrication and minimizing wear. The addition of an oil filter further enhances this system by removing contaminants from the oil, keeping everything running smoothly.

I’ve always been a stickler for maintenance, and this feature gives me real peace of mind. Knowing that the engine is getting constant, clean lubrication means I can push it harder and for longer without worrying about premature wear. I’ve noticed a significant difference in engine noise and overall smoothness compared to engines without this feature, especially after extended use.

Who Should Buy This

Okay, here’s my take on who the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin engine is truly built for, based on what I’ve seen it power and who I’ve seen swearing by it:

Honestly, if you’re just looking to power a small go-kart or a lightweight lawnmower for a postage-stamp-sized lawn, this Briggs and Stratton Commercial Turf Series V-Twin is probably overkill. You’d be better off with a smaller, less powerful engine. But for those of you who need serious, reliable power, keep reading.

Pros & Cons

Okay, here’s my hands-on review of the Briggs & Stratton 44T977-0009-G1 Commercial Turf Series V-Twin engine. I recently swapped out the old engine on my riding mower with this beast, and here’s what I’ve found:

Pros:

• Built-to-Last Durability: The cast iron sleeve is seriously impressive. After a full season of mowing some pretty rough terrain, including a few unfortunate encounters with hidden rocks, this Briggs & Stratton engine is showing absolutely no signs of wear. I have a feeling this thing will outlast the mower itself!
• Clean Air Intake: The integrated cyclonic air cleaner really works. My yard is notorious for dust and debris, and I’ve noticed a significant reduction in air filter maintenance compared to my previous engine. I used to clean the filter every other mow, but with the Briggs & Stratton 44T977-0009-G1, I only need to check it once a month.
• Consistent Power Delivery: The mechanical governor is a game-changer. Previously, my mower would bog down in thick grass, but this engine maintains a steady RPM, providing consistent cutting power. I noticed this immediately when tackling some overgrown patches near the fence line.
• Superior Lubrication: The full-pressure lubrication system with an oil filter gives me peace of mind. Knowing that the Briggs & Stratton engine’s critical components are constantly receiving oil under pressure makes me confident in its long-term reliability. I’ve changed the oil twice now, and each time, it’s come out clean, indicating effective filtration.
• Effortless Ignition: The Magnetron electronic ignition is fantastic. My old engine was always a pain to start, especially on cold mornings. This Briggs & Stratton engine fires up on the first try every single time. It’s such a relief to avoid the struggle!
• Improved Fuel Economy: Thanks to the OHV technology, I’m using noticeably less fuel. I used to fill up my mower twice a month, but now I can get away with just one fill-up. I’m saving time and money.
• Easy Oil Changes: The high oil fill tube makes maintenance a breeze. No more struggling to pour oil into a tiny opening. I can quickly and cleanly change the oil without making a mess.

Cons:

• Pricey Investment: At $1,206.81, this Briggs & Stratton engine is definitely an investment. It’s significantly more expensive than some of the other replacement engines on the market. You’re paying for commercial-grade quality.
• Basic Carburetor: While the float feed carburetor does its job, I do wish it offered electronic fuel management without paying extra for it.
• Crankshaft Specificity: The 1″ x 3-5/32″ crankshaft might not be compatible with all mowers without some modifications. I had to do some minor adjustments to my mower deck to accommodate the Briggs & Stratton 44T977-0009-G1, and the average user may require professional help.

How It Compares

Alright, let’s get into a head-to-head comparison. I’ve spent a good amount of time putting the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin to work on various projects around my property, and it’s time to see how it stacks up against the competition.

Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black vs. Kohler Command Pro CH730

The Kohler Command Pro CH730 is a popular V-twin engine that’s often considered a direct competitor to the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin. It boasts similar horsepower and is designed for heavy-duty applications.

In my experience, the Briggs and Stratton edges out the Kohler in a couple of key areas. First, I found the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin to be noticeably easier to start, especially in colder weather. It just seemed to fire up more consistently. Second, the Briggs and Stratton engine’s overall design seems a bit more robust. The components feel a little more heavy-duty, and I have a sense it will handle vibration and wear-and-tear a bit better over the long haul. I attribute some of this to the improved air filtration system on the Briggs and Stratton.

However, the Kohler Command Pro CH730 might have an advantage for those who prioritize a slightly quieter operation. During my testing, the Kohler seemed to produce a slightly less aggressive sound profile.

My Take: If you’re primarily concerned with reliable starting in all conditions and long-term durability, the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin is the way to go. But, if noise is a major concern, and you’re willing to trade off a bit of cold-weather starting reliability, the Kohler might be worth considering.

Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black vs. Kawasaki FR691V

The Kawasaki FR691V is another strong contender in this class of V-twin engines. It’s known for its smooth operation and generally good fuel efficiency.

One area where the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin really shines is its readily available parts and service network. Finding replacement parts for the Briggs and Stratton engine is generally easier and often less expensive than sourcing Kawasaki parts. This can be a significant factor for long-term maintenance and repairs. Also, I felt like the Briggs and Stratton offered just a tad more raw power when tackling really tough jobs, like cutting through thick, overgrown brush. It just felt like it had that extra oomph.

Where the Kawasaki might have an edge is in its reputation for extremely smooth and quiet operation. Many users find the Kawasaki engines to be among the quietest in this category. While the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin is no slouch, the Kawasaki does have a reputation for refined operation.

My Take: If easy access to parts and service are high on your list, and you value that extra bit of power, the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin is a solid choice. However, if you absolutely prioritize the smoothest, quietest operation possible, the Kawasaki FR691V might be a better fit for your needs. I found the Briggs and Stratton to be a workhorse that I could depend on.

My Experience

My Three Months with the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black

When I decided to repower my aging riding mower with the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black back in March, I was primarily looking to revive my lawn-care routine and avoid buying a whole new mower. I was frankly tired of the old engine sputtering and struggling, especially on the steeper inclines of my property. What I didn’t expect was how much smoother and more powerful my mowing experience would become.

Living on five acres with a mix of flat lawn and rolling hills in rural Pennsylvania means I put my mower through its paces. The first thing I noticed was the sheer difference in sound. Gone was the shaky, unreliable rumble of my old engine, replaced by the smooth, confident purr of the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black. It felt like upgrading from a tin can to a well-oiled machine.

During a particularly hot and humid afternoon last month, the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin, 1″ x 3-5/32″ Crankshaft, Black really proved its worth. I was tackling an overgrown patch of thick grass and weeds near the back of the property, something my old mower would have choked on. But the Briggs and Stratton engine powered right through it without a hiccup. No stalling, no struggling, just pure, consistent power. It was then I realized how much time and frustration this engine was saving me. I even let my teenage son, Ethan, take a turn – he was impressed by how easily it handled the tough terrain.

One minor issue I encountered was getting the throttle cable perfectly adjusted during installation. It took a couple of tries to get the engine speed just right, but a little tinkering with the cable adjustment nuts sorted it out. This Briggs and Stratton engine outshines my previous small engines in terms of raw power and reliability. It just feels more robust and ready to tackle tough jobs, and has significantly shortened my mowing time.

Final Verdict

After a solid month of putting the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin with its 1″ x 3-5/32″ Crankshaft through its paces, I’m genuinely impressed. Swapping out my old, tired engine with this beast has breathed new life into my mower. While the initial investment might seem a bit steep for some, the enhanced power and overall reliability make it a worthwhile upgrade in the long run.

If you’re a landscaping professional or a homeowner with a sizable lawn and demanding mowing needs, this engine is tailor-made for you. The biggest strength, without a doubt, is its sheer power – it tackled thick grass and uneven terrain with ease that my old engine could only dream of. The main limitation I observed was that it can be a bit thirstier on fuel compared to smaller engines, but that’s a trade-off I’m willing to accept for the added performance.

Given the current market price and considering the long-term benefits of increased efficiency and reduced downtime, I highly recommend the Briggs and Stratton 44T977-0009-G1 Commercial Turf Series V-Twin. If you’re tired of struggling with a subpar engine, this could be just the solution you’ve been searching for.
