Contact Drive Wheel Update Kit
Yield-Pro Ground Drive Planters
Used with:
• Pre-2007 12- and 16-row Yield-Pro Planters with ground drive
General Information
These instructions explain how to install the Contact
Drive Wheel Update Kit. This feature is now standard on
new products, and is available as an upgrade to provide
more consistent ground-drive performance in unusually
challenging conditions.
These instructions apply to:
Before You Start
Each kit converts an entire planter. Inventory the con-
tents per the “Parts List” on page 4. You may want to
check tire pressure on the new tire before installation.
Raise and fold the planter. Install lift cylinder locks
Note: Although this update can be performed with the
planter unfolded, it is much more complicated that
way. These instructions assume a folded planter.
If necessary, move the implement to a dry well-lighted
location suitable for disassembly.
Park and secure the implement. Secure the tractor if left
connected. Disconnect any hydraulic and electrical
power to the implement.
“Left” and “Right” are facing in the direction of machine
travel.
Have the following tools at hand:
• Basic hand tools (including an assortment of roll-pin
punches)
Also have an assistant for the wheel assembly portion of
this upgrade. Removing the old wheel and installing the
new wheel is not easily done by one person.
Installation
