Deutz (KHD) F1L 514/51 or John Deere Model B?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the F1L 514/51 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Model B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Deutz F1L 514/51 suits road haulage better on this data: 25% (4.0 km/h / 2.5 mph) more top speed.
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 Model B is 13% heavier (176 kg / 388 lb) than the Deutz F1L 514/51 (both unladen weight, as stated by the source).
- The Deutz F1L 514/51 has 25% more top speed (4.0 km/h / 2.5 mph) than the John Deere Model B (both top speed forward, as stated by the source).
- The Deutz F1L 514/51 is newer: production began 14 years later. We hold no parts-availability data, so there is no call on parts.
- Even on forward gears (both forward gears, as stated by the source): the figures vary by configuration and the ranges overlap.
- Even on PTO independence: every PTO is dependent.
- Even on drive: all two-wheel drive.
- Not comparable on power at the PTO shaft: the F1L 514/51 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Model B has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, three-point lift, maximum permissible mass, a creeper range and PTO speeds.
