I couldnt find a reliable source for a YFT12 mini excavator model its possible theres a typo, or it might be a less common/local model. However, I found specs for very similar models (like YFE12, YT12, YFE12A/B) which may be close. I can piece together what a mini excavator of that size is likely to have, so you can compare with your machine and see what matches. If you want, I can try dig up specifics for your serial/model if you give more details (engine type, country of origin, photos etc.).
Heres a typical description/specification for a 1.01.2 ton mini excavator in that class (like YFE12 / YT12 etc.), with key features & performance. You can adapt based on what matches YFT12.
A mini excavator in the 12 ton / 1.2 ton class (or 12 in model number) is a compact crawlertype earthmoving machine designed for light construction, landscaping, trenching, pipeline work, and other jobs where space is limited. It has a small swing radius, can work in tight spaces, often with rubber tracks, and usually have options for canopy or enclosed cab, different bucket sizes, etc.
| Parameter | Typical Value |

| Engine power | 811 kW ( 1014 HP) |
| Bucket capacity | 0.020.03 m |
| Digging depth | 1,5001,700 mm |
| Max digging height | 2,4002,600 mm |
| Maximum digging radius (on ground) | 2,8003,100 mm |
| Travel / moving speed | 1.22.5 km/h |
| Width | 0.91.1 m (can vary, tracks may retract for narrow width) |
| Hydraulic system | Auxiliary circuit for attachments, often external piping for hammer, auger etc. |
| Boom / arm design | Usually articulated with swing, sometimes sideswing arm, good maneuverability. |
| Undercarriage | Crawler tracks (rubber or steel), stable in uneven terrain. |
| Additional features | Removable canopy / shed, options for canopy or cabin, dozer blade (float or nonfloat), tilt boom (on some), quick couplers, etc. |
Engine from a known brand (e.g. Briggs & Stratton, Koop, Kubota etc.) for reliability.
Rubber tracks to reduce surface damage and improve portability.
Strong hydraulic pumps with good response and likely energy saving features.
Good cooling/radiator system to maintain temperature under load.
Possibly side digging / side shift capability for working against walls or in tight spaces.
Structure built with robot welding or automated welding to ensure strength in joints.
Standard bucket plus optionally several bucket sizes.
If you want, I can try to find the exact spec of YFT12 if you can tell me:
what country or maker it is (manufacturer)
engine make/model (if you know)
weight or any dimension youve seen
