Tillage & Cultivation


Part 1 – 78 | Unit 1.2


Basic tractor configurations:


Standard – basic 2 wheel drive (2WD) tractor in the
25 to 40 HP range


Row Crop – 2WD high clearance, adjustable tire
width, upright exhaust, 12-inch rear tires, 25 to 50
HP (occasionally with belly bar cultivators)


Compact Utility – 25 to 35 HP 4WD with front
loader, 16-inch rear tires, non-aggressive tire tread,
often hydrostatic transmission


Mudder – 80 HP 4WD “row crop,” front and rear
tires same diameter


Orchard – very wide tires, fenders, low clearance,
exhaust out the back


Vineyard – very narrow


Industrial – Front loader, 2 or 4 WD, painted yellow,
non-aggressive tire tread


Crawler – “caterpillar” or “track layer” tractor used
for high traction applications. Good stability on
steep slopes, minimal compaction, very expensive to
work on.
Many small-scale row crop operations (5–10
acres) use “Standard” and “Compact Utility” con-
figurations. Many medium-scale row crop opera-
tions (10–25 acres) use “Row Crop” configurations
and most larger row crop operations (25 acres and
up) utilize “Mudder” configurations.
