Balers may have two separate hydraulic systems powered by the tractor:

  • One system controls bale tension and operates gate.
  • The other system operates twine wrapping mechanism, if equipped with BALEWATCH™ System.

An optional hydraulic bale ramp is available. Bale ramp is operated by bale tension/gate control system.

Two sets of hydraulic outlets are required to operate baler.

An additional set of hydraulic outlets is needed if baler is equipped with optional hydraulic pickup lift.

The hydraulic system uses the following major components:

  • Tensioning valve (C)-Used to direct oil flow, check flow, and limit hydraulic pressures.
  • Tension/gate (double-acting) cylinders (F)-Used to raise and lower gate and to control bale tensioning.
  • Take-up (single-acting) cylinder (D)-Used to provide proper sequencing between the tension arm and gate opening. Also, it helps control belt slack during gate closing to avoid belt pinching.
  • If equipped, twine arm (double-acting) cylinder (B)-Used to actuate twine arms to wrap bale.
  • If equipped, flow control valve (L)-Used to regulate twine arm "sweep" time.
  • Optional pickup lift (double-acting) cylinder (K)-Used to raise and lower pickup using tractor SCV.
  • Optional bale ramp (double-acting) cylinder (G)-Used to automatically lower/raise bale ramp when gate is opened fully.
  • Optional regulator valve (E)-Used to regulate flow to and from optional bale ramp cylinder (G) for proper sequencing of ramp and gate positions.
  • Gate lock valve (J)-Used to block flow of oil to and from base ports of tension/gate cylinders (F).
