SOMECA 450-N (DT) or UZINA TRACTORUL R-450 (DT)?
Which should you choose?
On performance, no comparable figure differs by more than its threshold: on this data the machines are level.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.
What decides it, question by question?

| Which may carry more ballast and load? | — | — | No figureNo call on maximum permissible mass: no figure on record for the 450-N (DT) and the R-450 (DT). |
| Which has the wider choice of gears? | 6 to 9Traktorenlexikon, “Someca 450 N” | 6 to 9Traktorenlexikon, “UTB 450 (DT)” | EvenEven on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap. |
| Which offers a creeper range? | — | — | No figureNo call on a creeper range: not stated for the 450-N (DT) and the R-450 (DT). |

| Which offers more PTO speeds? | 540 rpmTraktorenlexikon, “Someca 450 N” | 540 rpmTraktorenlexikon, “UTB 450 (DT)” | EvenEven on PTO speeds: the same speeds (540 rpm). |
| Which PTO runs independently of the ground drive? | — | — | No figureNo call on PTO independence: not stated for the 450-N (DT) and the R-450 (DT). |
| Which drives on both axles? | Two-wheel or four-wheel driveTraktorenlexikon, “Someca 450 N” | Two-wheel or four-wheel driveTraktorenlexikon, “UTB 450 (DT)” | EvenEven on drive: every machine is available with four-wheel drive. |
| Which is newer, and what about parts? | 1970–1977 | 1974–1981 | EvenSame era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts. |
What does this mean in plain words?
- Even on power at the PTO shaft (both power at the PTO, claimed): the difference is under the 10% threshold for claimed figures, too small to call.
- Even on hydraulic flow (both pump flow, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on three-point lift (both lift at the hitch ends, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on top speed (both top speed forward, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: every machine is available with four-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range and PTO independence.
