Product Introduction
The GR1653 motor grader is a heavy-duty earthmoving machine with comprehensive performance, precise control and durability. It perfectly inherits XG's technological accumulation in the field of construction machinery. Its powerful performance, unparalleled operational flexibility, excellent leveling accuracy and driver comfort make it an indispensable key equipment in various large-scale earthwork leveling projects. Whether it is high-standard highway subgrade construction or large-scale site leveling, GR1653 can provide efficient and reliable solutions, and is a powerful assistant for users to create value.
Product Advantage
The articulation frame is adopted and matched with the steering of the front wheel, With small turning radius,maneuvering and flexible. The electro-hydraulic controls the power shift gearbox,with 6ahead gears and 3 back gears. The international matching hydraulic parts are adopted,with reliable operation. The motions of the blade are fully hydraulically controlled. The rear axle is the three-section driving axle which is provided with the NO-SPIN self-locking differential mechanism.

Product Uses
High-grade highways: Used for fine leveling and shaping of roadbeds.
Airport runway: The final leveling of large areas of land, with extremely high precision requirements.
Farmland water conservancy: Land leveling and ditch excavation for large-scale farmland.
Mine site: Maintenance of mine roads and leveling of working platforms.
Snow removal operations: After installing a snow shovel, large-scale snow removal operations can be carried out.
Product Operate Guide
Smart Leveling:
Calibrate the reference surface before enabling the automatic leveling system
Select laser/GPS positioning mode based on working conditions
Efficient Operation:
Use the standard angle of “15° forward tilt of the blade” for precise leveling
Maintain a constant speed of 3-5 km/h during layered leveling
Safety Points:
Engage the differential lock when operating in complex terrain
Replace the blade immediately if wear exceeds 30%
Maintain lateral stability when operating on slopes
Maintenance Tips:
Check the hydraulic oil level every 8 hours
Clean accumulated material buildup daily
Regularly lubricate the blade rotation mechanism
FAQ
1.How often should hydraulic oil be replaced?
A: Strictly follow the cycles stipulated in the official operation manual, usually based on working hours. For example:
First replacement: Generally around 500 hours (after the running-in period).
Subsequent replacement: Usually every 2,000 hours or once a year (whichever comes first).
Note: If the hydraulic oil is contaminated (water enters, turns milky white, has metal shavings) or deteriorates, it must be replaced immediately, regardless of whether the time is up or not.
2.When operating a motor grader, how to choose the correct Angle of the blade?
A: The Angle of the scraper needs to be adjusted according to the specific operation content
Leveling operation: The scraper can be set at a smaller positive Angle (with the tip facing forward), which is conducive to the forward rolling of materials and enables smooth pushing.
Slope scraping operation: It is necessary to utilize the rotation function of the scraper to form a certain Angle with the slope surface.
Soil transfer operation: A larger negative Angle (with the blade tip backward) can be adopted to increase the cutting depth and improve efficiency.
Principle: Start with a small Angle and make fine adjustments based on the actual effect and engine load to avoid engine stalling or severe impact on the equipment due to an overly large Angle.
3.Why does the traction of my motor grader feel insufficient?
A: Possible reasons include:
Improper tire pressure: Excessive pressure can reduce the ground contact area and cause skidding. If the pressure is too low, the resistance will be too large. Inflation should be carried out at the pressure specified in the manual.
The differential lock is not activated: When working on muddy and soft roads, the differential lock should be activated to prevent one side of the wheels from slipping and enhance the ability to get out of difficult situations.
The blade cuts too deep: The load is too heavy, exceeding the traction force of the engine. The blade should be appropriately raised or the cutting Angle reduced.
The transmission gear is too high: Under heavy-load conditions, a low gear should be used to provide greater torque.
4.How to troubleshoot if the scraper moves slowly or unstably during operation?
A: Possible causes:
The hydraulic oil level is too low: It causes the pump to suck air. Check and add it to the standard oil level.
Hydraulic oil filter element blockage: It causes poor oil passage. Check and replace the filter element.
Insufficient pilot pressure or main pressure: Professional technicians are required to use a pressure gauge to detect the system pressure.
If the valve core of the multi-way valve is stuck or leaking internally: The valve assembly needs to be cleaned or replaced.
