Technical Features of the Kohler KT19
The Kohler KT19 is a 770 cc, two-cylinder, air-cooled, four-stroke gasoline engine. Its L-head design and horizontal PTO shaft are defining characteristics. Fuel delivery is handled by a side-draft carburetor, and ignition is powered by a battery system. The engine boasts a power output of 19.3 PS (14.2 kW; 19.0 HP) at 3,600 rpm. Lubrication systems vary depending on the engine series. The KT19 utilizes either a pressurized spray system or a full-pressure system, depending on the manufacturing date.
The following table summarizes the key technical specifications:

Kohler KT19 Series Variations
The KT19 engine is available in several variations, each denoted by a suffix in the model code. These suffixes indicate additional features or configurations. Discussions on forums like www.mytractorforum.com often highlight the differences in performance and maintenance between these series. The information below is compiled from various sources including www.wersis.net and www.engine-specs.net.
| Suffix | Description |
|---|---|
| S | Electric starter |
| G | Tapered crankshaft |
| P | Threaded crankshaft |
| EP | Electric plant |
| Q | Quieter model |
Further differentiating the KT19 are the Series I and Series II models. The main difference lies in the lubrication system. Series I engines use a pressurized spray system, while Series II engines feature a full-pressure system with an oil filter. This upgrade improved lubrication and overall engine longevity, as evidenced by user experiences on www.mytractorforum.com.
| Series | Lubrication System | Oil Filter |
|---|---|---|
| I | Pressurized spray system | No |
| II | Full-pressure system | Yes |
KT17 vs. KT19: A Comparison
The Kohler KT17 and KT19 engines share a similar design philosophy, but key differences exist. Forums such as www.wfmachines.com often feature discussions comparing these models. While both have a 79.375 mm bore, the KT19 has a longer stroke (77.8 mm vs 69.8 mm for the KT17), resulting in a larger displacement and higher horsepower. The crankshaft, connecting rods, and pistons are all different between the two models. However, some parts, such as the piston rings, are interchangeable.
| Feature | KT17 | KT19 |
|---|---|---|
| Bore (mm) | 79.375 | 79.375 |
| Stroke (mm) | 69.8 | 77.8 |
| Displacement (cc) | ~680 | 770 |
| Horsepower | ~17 | 19 |
| Crankshaft | Different | Different |
| Connecting Rods | Different | Different |
| Pistons | Different | Different |
| Piston Rings | Same (generally) | Same (generally) |
Conclusion
The Kohler KT19 engine, with its various configurations and series, represents a significant piece of small engine history. While some users on forums such as www.mytractorforum.com have reported issues, particularly with older models and inadequate maintenance, many others have experienced long-term reliable service.

FAQs
1. Are Kohler KT19 engines reliable?
Reliability depends heavily on maintenance. Proper oil changes, filter replacements, and regular servicing are key. Older models (Series I) may have lubrication issues on slopes. Well-maintained KT19s can provide many years of service.
2. What are the common problems with Kohler KT19 engines?
Common issues include lubrication problems (especially in Series I on slopes), worn piston rings leading to blue smoke, and carburetor problems. High parts costs for older models are also a frequent concern.
3. Can I use KT17 parts on a KT19 engine?
Some parts, like piston rings, are often interchangeable. However, the crankshaft, connecting rods, and pistons are different and not interchangeable. Always refer to the parts manual for your specific engine model.
4. What is the difference between Kohler KT19 Series I and Series II?
The primary difference is the lubrication system. Series I uses a pressurized spray system, while Series II uses a full-pressure system with an oil filter. Series II offers improved lubrication and longevity.
5. Should I rebuild or replace a worn KT19 engine?
The decision depends on the extent of the wear and your mechanical skills. A rebuild is often more cost-effective for minor issues, while a replacement might be necessary for major internal damage. The high cost of parts for older models should also be considered.
