Set the amount of knives used as described under Remove or Install Precutter Knives (10-, 15-, or 23-Knife Precutter) in Preparing the Baler section.

On 23-knife precutter, the cutting length depends on the number of knives engaged. When all 23 knives are engaged, the crop is cut at a length of 45 mm (1.77 in).

  1. Engage and run PTO at 1000 rpm.

  2. Wait until hydraulic circuit pressure has built up.

    • Press engage knives button (A) to move the knives in. The precutter knives engaged indicator (B) appears on-screen.
    • Press retract knives button (C) to move out the knives. The precutter knives engaged indicator (B) disappears. Retract knives button (C) appears only if knives have been previously engaged.

    Check at pressure gauges (D) or (E) that requested group of knives is engaged.

    • A pressure of about 12 500 kPa (125 bar) (1958 psi) at gauge (D) indicates that the group of 12 knives is engaged.
    • A pressure of about 12 500 kPa (125 bar) (1958 psi) at gauge (E) indicates that the group of 11 knives is engaged.
    • A pressure of about 12 500 kPa (125 bar) (1958 psi) at both gauges (D) and (E) indicates that the 23 knives are engaged.
