    Serious injury or death to the operator or others could result if the operator is under the influence of drugs or alcohol. (SG-27) FN180/FN120 07/12 Operation Section 4-3 © 2012 Alamo Group Inc.

  • Page 110: Tractor Requirements

    For most mowing conditions, the FN180/120 NITRO mower requires a tractor with a minimum of 70 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 100 HP for a 540 RPM drive and 140 HP for a 1000 RPM drive may cause mower damage by overpowering the unit in heavy cutting conditions.
