The 1635 lands between two common thresholds. Its 26.0 (HST) or 27.6 (Shuttle) PTO hp clears 25-hp minimums by a narrow margin and stays below 30-hp classes, while its 36.2-hp engine already exceeds some engine-rated upper limits.

FROM YOUR TRACTOR TO THE JOB
A 1635 opens the 25-PTO-hp chipper class, but only just: the HST clears MX-9900 and FH-BX62S by 1.0 hp, the Shuttle by 2.6. Its 36.2-hp engine also exceeds Wallenstein BX36S’s 30-engine-hp maximum, so a smaller chipper is not automatically the safer choice.
Read the guide →FIELD GUIDEA 1635 has outgrown the 25-hp flails and not yet reached the 30-hp class. Its 26.0 or 27.6 PTO hp exceeds FM-54’s 25-hp maximum, falls short of FM-78’s 30-hp minimum, and lands inside the 55–60-inch hammer and Y options. Several mowers do not say whether they mean engine or PTO horsepower, and on this tractor that choice changes the answer.
