The John Deere 4475 left the factory with the 3TNE84. Where that engine is no longer available, the Yanmar 3TNV88 is the established replacement - same engine family, same mounting layout, a little more displacement. We stock it in mechanical injection and in electronic common rail, new surplus and rebuilt.

WHAT WE FIT TO YOUR MACHINE.
On a skid steer the engine sits transversely behind the operator, driving the hydrostatic pumps directly. The bellhousing, pump coupler, oil pan and cooling package all have to match the machine - they are external parts and they come across from the engine you are replacing.
WHY THE 3TNV88 REPLACES THE 3TNE84.
Yanmar's TNV three-cylinder engines are one family on one architecture - same 90 mm stroke, same block design, same mounting and accessory layout. Only the bore changes: 82
