Steering
Never exceed 13 mph (22 kph) in turns. The 3PYP is
extremely heavy, and can cause “over-steer” with most
tractors. Above 8 mph the rear wheels caster and
provide only modest resistance to side sway by the
planter.
If not equipped with Steering, the rear wheels on the
3PYP are full castering at all times.
If your 3PYP is equipped with hydraulic Steering, it is
normally engaged at all times when speed is less than
8 mph. Although not used during forward motion in
transport, it MUST be engaged for any backing. See
“Steering” on page 151
Never exceed 3 mph (5 kph) in reverse.
Machine Damage Risk:
Never back up with the planter lowered.
Machine Damage Risk:
If planter has optional steering, never back up without
steering engaged.
