Kato HD excavators: how the number signals weight class and MR/LC the undercarriage
Kato has built hydraulic excavators since 1967, marking them with the "HD" code plus a model number. Across several model pairs in the SpecCodex database, the trailing digits of the number visibly track the approximate weight class in tonnes — the 40 recorded HD models span 10,500 to 46,200 kg operating weight, from compact to large building-site excavators.

Trailing letters denote the body configuration: "MR" (Minimal/Mid Radius) marks machines with an especially short rear overhang for tight job sites, while "LC" (Long Crawler) denotes widened, elongated tracks giving more ground contact on soft terrain. Further suffixes such as "E" or "V" mark additional equipment or control variants within the same weight class.
For the machines recorded in the database, engine output ranges from 61 to 235 kW, displacement from 3,298 to 11,946 cm³, torque from 294 to 1,245 Nm, and cylinder count from 4 to 6.
When buying an MR variant, check the condition of the short rear body and counterweight mounting; on LC models, check track tension and track-pad wear. In general, check the hour meter, hydraulic cylinder seal condition, and test the bucket and boom under load. Models such as HD512, HD820, HD513MR and HD820LC illustrate the range of body configurations.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
