This guide covers kawasaki vs briggs & stratton engine. Verdict: Choose the Briggs & Stratton 20hp Intek example if your mower needs a common replacement engine for a consumer riding mower or z-turn and the crankshaft size matches. Choose the Briggs & Stratton 25 GHP vertical shaft example if the cast iron sleeve, overhead valve design and full pressure lubrication matter more to you. The listings reviewed here give no Kawasaki example, so pick a Kawasaki engine only after comparing a Kawasaki listing on the same stated specs.
On a property where a riding mower does the weekly work, the engine decides whether the mower runs or sits in the shed. The kawasaki vs briggs & stratton engine question usually comes down to fit, power and build, but the listings reviewed here tell only part of that story: both examples are Briggs & Stratton engines, and no Kawasaki listing is included. This comparison works through what the two Briggs & Stratton examples state, where they differ, and what stays unstated about the Kawasaki side.

Briggs & Stratton 40N777-0027 20hp 656cc Intek Series
A 20hp Intek V-Twin replacement engine, listed as a common replacement engine for consumer riding mowers and z-turns, with a 1" x 3-5/32" crankshaft and 9 Amp charging.
Read the full review
The 20hp Intek example is the clearer replacement pick of the two listings: it states 20hp, 656cc, a V-Twin layout and a 1" x 3-5/32" crankshaft, and it names its job as a common replacement engine for consumer riding mowers and z-turns. The listing is also plain about fit: measure the old engine crankshaft first, because Briggs makes several sizes, and note that the mounting holes are drilled only.
Pros
- 20hp Intek V-Twin engine with 656cc stated
- Listed as a common replacement engine for consumer riding mowers and z-turns
- Crankshaft size stated as 1" x 3-5/32" for fit checking
- Weight and dimensions stated: 95.0 pounds and 24.0 inches x 20.0 inches x 20.0 inches
Cons
- Mounting holes are drilled only, so use a nut and bolt or the self-tapping bolts from the existing equipment
- The listing warns to measure the old engine crankshaft, since Briggs makes several crankshaft sizes
- No cylinder, lubrication or charging detail beyond 9 Amp is stated
- No warranty term is stated on the listing
Briggs & Stratton 44S977-0032-G1 25 GHP Vertical Shaft Engine
A 25 GHP vertical shaft engine with a dura-bore cast iron cylinder sleeve, overhead valve design, full pressure lubrication with oil filtered, a PTO bearing and a 16 amp charging system.
Read the full review
The 25 GHP example leans on build detail rather than fit detail: it states a dura-bore cast iron cylinder sleeve, an overhead valve design, full pressure lubrication with oil filtered, a PTO bearing and a 16 amp charging system. What it does not state is just as important: no displacement, no crankshaft size and no mower fit, so a buyer cannot check it against an old engine from this listing alone. The title states 25 GHP while the bullets give no horsepower figure, so the two power figures in this article use different labels, hp against GHP, and the listings give no shared basis for comparing them.
Pros
- Dura-bore cast iron cylinder sleeve for extended life, per the listing
- Overhead valve design for cooler operation and long valve life, per the listing
- Full pressure lubrication with oil filtered, plus a PTO bearing
- 16 amp charging system stated
Cons
- No displacement figure is stated, so power cannot be compared on cc
- Power is stated only as 25 GHP in the title, with no horsepower figure in the bullets
- No crankshaft size is stated for fit checking
- No mower fit and no warranty term is stated on the listing

Figures are as stated in the listings for the examples, collected 2 November 2026.
Power and displacement
The 20hp Intek example states both power and displacement: 20hp in the title and 656cc of displacement in the extracted facts. The 25 GHP example states power only as 25 GHP in its title, with no displacement figure anywhere in its bullets or spec table. That gap matters, because the two power figures use different labels, hp against GHP, and the listings give no shared basis for comparing them, so the listings alone do not settle which example is stronger.
Build and lubrication
Build detail runs the other way. The 25 GHP example states a dura-bore cast iron cylinder sleeve for extended life, an overhead valve design for cooler operation and long valve life, full pressure lubrication with oil filtered and a PTO bearing. The 20hp example states none of that cylinder or lubrication detail; its build case rests on the V-Twin layout and the stated replacement role. Neither listing states a safety feature or a warranty term.
Fit: crankshaft, weight and size
Fit is where the 20hp example earns its keep. It states a 1″ x 3-5/32″ crankshaft and warns the buyer to measure the old engine crankshaft, since Briggs makes several sizes, and it notes the mounting holes are drilled only, so the buyer reuses a nut and bolt or the self-tapping bolts from the existing equipment. The 25 GHP example states no crankshaft size at all, so its fit cannot be checked from the listing. Both listings state weight and dimensions: the 20hp example at 95.0 pounds and 24.0 inches x 20.0 inches x 20.0 inches, and the 25 GHP example at 83.996121822 pounds and 19.0 inches x 16.0 inches x 18.0 inches.
Charging
Charging is one spec both listings state clearly, and here the 25 GHP example states the higher figure: a 16 amp charging system against 9 Amp on the 20hp example. That is a stated difference, not a verdict on the whole engine.

Matching It to Your Property
- Measure the old engine crankshaft before ordering: the 20hp example uses 1″ x 3-5/32″, and the listing warns Briggs makes other sizes.
- Plan for drilled-only mounting holes on the 20hp example: reuse the nut and bolt or the self-tapping bolts from the existing equipment.
- Check storage space against the stated dimensions: the 20hp example measures 24.0 inches x 20.0 inches x 20.0 inches and the 25 GHP example measures 19.0 inches x 16.0 inches x 18.0 inches.
- Match the engine to the machine, not the yard alone: the 20hp example is listed as a common replacement for consumer riding mowers and z-turns, while the 25 GHP example states no mower fit, so confirm fit before ordering.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty, and a factor the listing does not state scores zero, which is why both examples score zero for safety and warranty. The 20hp example ranks first on stated displacement and fit detail; the 25 GHP example follows on build detail and charging.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Briggs 20hp Intek | 9.5 | 30 | 21 | 21 | 0 | 0 |
| Briggs 25 GHP | 9.5 | 29 | 21 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
If you mow open ground with a riding mower, see our riding mowers for the machines these engines fit.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
FAQ: mowing large lots
Which example states more power?
The listings alone do not settle it. The 20hp example states 20hp and 656cc, while the 25 GHP example states only 25 GHP in its title, with no displacement figure, so the two power figures use different labels, hp against GHP, and the listings give no shared basis for comparing them.
What crankshaft size does the 20hp example use?
The listing states 1″ x 3-5/32″ and warns the buyer to measure the old engine crankshaft first, since Briggs makes several sizes.
Does either listing state a warranty?
No warranty term is stated on either listing, so both examples score zero for warranty.
Why is there no Kawasaki example here?
The listings reviewed here include two Briggs & Stratton engines and no Kawasaki engine, so compare a Kawasaki listing on the same stated specs before choosing that side.
What should I check before ordering a replacement engine?
Check the old crankshaft size, the mounting holes, the stated weight and dimensions for handling and storage, and the stated charging figure. The 20hp example also warns that its mounting holes are drilled only.
