A performance check for the baler can be done after baler break-in period of approximately 50 bales.
1.
Set tractor tires at least as MegaWide as the baler pickup (inside tire-to-tire dimension). (See ADJUSTING TRACTOR WHEELS in Preparing the Tractor section.)
2.
Form a uniform windrow full width of baler pickup long enough to make one complete bale. Windrow width should be:
-
457 and 457S Baler
; 1.22 m (4 ft)
-
557 Baler
; 1.52 m (5 ft)
3.
If equipped with variable core valve, adjust bale density for maximum density. (See OPERATING VARIABLE CORE [IF EQUIPPED] in this section.)

4.
Run tractor at 1800-2000 rpm. Certain crop conditions may require reduced engine speed and shifting transmission to higher gear to maintain ground speed. Select a gear that will be approximately 6-8 km/h (4-5 mph).
5.
Bale windrow. Observe the bale shape indicators on the monitor.
As the bale is being formed, bale shape indicator needles should be toward the top of their range and at the same location.
6.
Bale should be tight with uniform density and even on both corners. If not, refer to Troubleshooting section.
