Tractor Requirements
To operate your Great Plains End Wheel No-Till Drill in
most field conditions, a tractor of adequate size should
be used. For 7’ drills, a 55 horsepower tractor is re-
quired. For 10’ drills, a 75 horsepower tractor is required.
7’ and 10’ drills require one set of remote outlets.
Tractor Drawbar Hook-Up
Refer to Figure 2-2 & Figure 2-3:
The Great Plains No-Till Drill is equipped with either a
single strap, Figure 2-2, clevis style hitch, Figure 2-3, or
a ball swivel hitch, Figure 2-5. For proper field operation,
the tongue of the drill should run level, parallel to the
ground in field position.
