John Deere 2120 (A) or SOMECA 640 (TD)?
Which should you choose?
On performance, every comparable figure that differs favours the John Deere 2120 (A): three-point lift.
- The John Deere 2120 (A) suits loader and hydraulic implement work better on this data: 11% (210 kg / 463 lb) more three-point lift.
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 does this mean in plain words?
- The John Deere 2120 (A) has 11% more lift (210 kg / 463 lb) than the SOMECA 640 (TD) (both lift at the hitch ends, as stated by the source).
- The John Deere 2120 (A) is 36% heavier (762 kg / 1,680 lb) than the SOMECA 640 (TD) (both unladen weight, as stated by the source).
- The SOMECA 640 (TD) is newer: production began 5 years later. We hold no parts-availability data, so there is no call on parts.
- 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 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 figures vary by configuration and the ranges overlap.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: every machine is available with four-wheel drive.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
