Deutz (KHD) D 4506 or Porsche-Diesel Super L 318?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the D 4506 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super L 318 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Deutz D 4506 suits loader and hydraulic implement work better on this data: 37% (7.4 L/min / 2.0 gpm) more hydraulic flow.
- The Deutz D 4506 suits heavy draft work (ploughing, cultivating) better on this data: four-wheel drive.
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 Deutz D 4506 has 37% more hydraulic flow (7.4 L/min / 2.0 gpm) than the Porsche-Diesel Super L 318 (both pump flow, as stated by the source).
- The Deutz D 4506 is available with four-wheel drive; the Porsche-Diesel Super L 318 is two-wheel drive (as stated by the sources).
- The Deutz D 4506 is newer: production began 12 years later. We hold no parts-availability data, so there is no call on parts.
- 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 difference is under the 25% threshold, too small to call.
- Even on top speed (both top speed forward, as stated by the source): the figures vary by configuration and the ranges overlap.
- Not comparable on power at the PTO shaft: the D 4506 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super L 318 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the D 4506: lift at the hitch ends, as stated by the source (Traktorenlexikon, “Deutz D 4506”); the Super L 318: lift at an unstated point, as stated by the source (Traktorenlexikon, “Porsche-Diesel Super L 318”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, maximum permissible mass, a creeper range, PTO speeds and PTO independence.
