Choosing a single-cylinder diesel engine for small agricultural implements comes down to matching the motor to the machine you already own. A shaft that points the wrong way or an assembly job you did not expect can turn a simple swap into a weekend project. This head-to-head compares two single-cylinder diesel engines in this space, so you can see which one lines up with your equipment and your preferred level of setup.
Quick Verdict
The first engine is built for speed-minded buyers; the second is built for setup-minded buyers. Decide which trade-off matters more before you lock in a choice, then use the comparison table to confirm the mechanical details.

Product Notes
4 Stroke Diesel Engine Motor Single Cylinder For Small Agricultural Machinery
At USD 193.21, this engine carries the higher listed price of the pair. The listing specifies a horizontal crankshaft, forced air cooling, and a bore diameter of 68mm. Assembly is required, so plan on mounting and connecting the unit yourself. The recoil start system is a practical convenience for a small engine, and the listed 3800rpm output makes this the faster of the two. The clearest limitation is the assembly step: if you want a ready-to-run motor, this unit asks for more setup time before it can do the job.
Diesel Engine Motor Single Cylinder Air Cooled For Small Agricultural Machinery
At USD 138.60, this is the lower-listed-price engine in the pair. The listing calls out a vertical crankshaft, air cooling, and a bore/stroke of 68×54mm. It also includes a 22:1 compression ratio and a 3L fuel tank, with an aluminum alloy body described as durable and rust-resistant. The listed speed is 3000rpm, which is lower than the other engine's 3800rpm, so the trade-off is a slower output in exchange for a roomier fuel supply. If your job can run at that speed, the lower listed price and larger tank are the practical wins here.
Final Choice by Use Case
Use the comparison table to match shaft direction and cooling method to your equipment, then choose the engine whose listed price fits your budget. For a lower listed price, go with the Diesel Engine Motor Single Cylinder Air Cooled For Small Agricultural Machinery; for a higher listed price, go with the 4 Stroke Diesel Engine Motor Single Cylinder For Small Agricultural Machinery. The $54.61 gap between the two listed prices is the budget question you answer after the layout decision.
