PTO Pump Kits
For tractors lacking a sufficient number of remotes with
adequate continuous oil flow capability, kits are available
to operate the fan(s) optionally the hydraulic seed drive
motor, via mechanical Power Take-Off (PTO).
A 1000 rpm PTO is required with either:
1
3
⁄
4
inch. (44.5 mm) 20-spline shaft, or
1
3
⁄
8
inch (35 mm) 21-spline shaft.
Order one kit and one coupler.
Operation and installation of the PTO kits is described in
manual 411-015M, included with each kit.
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 81)
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 “Low Speed Kit Installation” on page 146.
