Functions of graders on agricultural land
- Precision land leveling: Removing undulations and establishing uniform slopes to improve flood and furrow irrigation efficiency.
- Farm road construction and maintenance: Clearing ruts, crowning farm roads, and maintaining ditches for heavy tractor and trolley movement.
- Drainage management: Cutting boundary ditches and watercourses to evacuate waterlogged fields during heavy monsoons.
- Field boundary shaping: Building robust earthen bunds and terrace ridges in undulating and sloping agricultural landscapes.
Motor graders vs tractor rear blades
Self-propelled motor graders are utilized primarily for major land contouring, large commercial farm development, and watershed earthwork. For routine field leveling and canal maintenance, farmers use three-point hitch tractor-mounted rear scraper blades, which can be angled horizontally and tilted vertically.
Operational guidelines and subsidy support
Land grading should be conducted when soil moisture is low to avoid soil compaction and blade clogging. Under the Sub-Mission on Agricultural Mechanization (SMAM), tractor-operated grading blades and leveling implements are eligible for government subsidies when purchased through authorized dealers.

Common questions
How does a grader differ from a standard scraper?
A grader features a multi-angle rotatable blade capable of shaping slopes and crowning roads, whereas scrapers primarily load and haul bulk soil.
Why is field grading important for irrigation?
Uniform grading prevents water pooling in depressions and ensures irrigation water spreads evenly across the entire cropped area.
Can farmers receive subsidies for tractor-mounted graders?
Yes, tractor-drawn scraper and grading implements are covered under the Sub-Mission on Agricultural Mechanization (SMAM) implement roster.
