Why does my Swift MAJOR MJ70-190 leave uncut grass?
- S
  shane80Aug 15, 2025
  Your Swift Farm Equipment may be leaving streaks of uncut or partially cut grass due to several reasons: * Dull or bent blades: Replace the blades. * Low carrier RPM: Ensure you are using the correct PTO speed. * Wet field conditions: Stop operation and wait until the field is drier. * Fast ground speed: Reduce ground speed by shifting to a lower gear. * Grass down from previous weather: Mow in only one direction. * Material build-up: Clean the machine. * Incorrectly mounted blades: Change blades so that the cutting edge faces the correct rotation.

Why does my Swift Farm Equipment discharge material unevenly?
- M
  Michael CollinsAug 28, 2025
  Uneven material discharge from your Swift Farm Equipment, resulting in bunches of material along the swath, can be caused by: * Material being too high or too much: Reduce ground speed while maintaining recommended RPM at the tractor PTO, or make two passes over the material, raising the machine for the first pass and lowering it to the desired height for the second pass, cutting at a 90-degree angle to the first pass. * Grass being wet: Allow the grass to dry before mowing, slow down the tractor's ground speed while keeping the engine running at full PTO RPM, and cutting lower may also help.
