Low Speed Kit
Combinations of narrow row spacings, high cell count or
fingers per revolution, low populations and/or low field
speed can result in the hydraulic seed meter motor
operating at an rpm too low for consistent control by the
proportional valve.
If the remedies in the Troubleshooting chart (page 92)
are not available, order a low speed kit to replace the
standard motor output sprocket with one having fewer
teeth that increases motor speed by 160%.
See “402-520A Low Speed Kit Installation” on
page 175.
Markers
Markers are a standard factory-installed feature on the
YP40 planter, but may be optionally deleted (line item
401-569A), for example, if all planting is done via GPS
navigation.
If any possible future planting (or re-sale considerations)
might require markers, do not delete them from the initial
YP40 planter order.
For operations, see:
“Fold Cylinder Bleeding” on page 97,
“Marker Unfolding” on page 40,
“Folding the Markers” on page 41, and
“Marker Adjustments” on page 60.
Note: This option is compatible with the YP4025F.
Trailer Hitch Weldment
This accessory provides a 20 ton pintle hook intended for
use with either the PFC1600 or PFC2000 tank carts.
Note: This option is compatible with the YP4025F.
This kit applies to multiple implements, and includes a
step section that is not used on the YP40.
