Agco RT-155 A or Deutz-Fahr AgroStar 6.81?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the RT-155 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the AgroStar 6.81 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Agco RT-155 A suits loader and hydraulic implement work better on this data: 40% (32.9 L/min / 8.7 gpm) more hydraulic flow.
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 Agco RT-155 A has 40% more hydraulic flow (32.9 L/min / 8.7 gpm) than the Deutz-Fahr AgroStar 6.81 (both pump flow, as stated by the source).
- The Deutz-Fahr AgroStar 6.81 offers 750 rpm at the PTO, which the Agco RT-155 A does not (as stated by the sources).
- The Agco RT-155 A is newer: production began 13 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.
- Transmissions differ in kind: the Agco RT-155 A is stepless (CVT) and the Deutz-Fahr AgroStar 6.81 has 18 forward gears — not called.
- 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 independence: every PTO is independent.
- Even on drive: every machine is available with four-wheel drive.
- Not comparable on power at the PTO shaft: the RT-155 A has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the AgroStar 6.81 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, three-point lift, maximum permissible mass and a creeper range.
