Working Principle of a 3 Point Hitch Tractor PTO Driven Disc Drum Mower

A 3-point hitch tractor PTO driven disc drum mower operates on a simple yet effective mechanism. Here??s a breakdown of its working principle:

• Attachment to the tractor: The disc drum mower is connected to the tractor using a 3-point hitch system. This allows for easy attachment and detachment and provides stability during operation.
• Power transmission: The mower is powered by the tractor's PTO, which transfers power from the tractor's engine to the mower through a rotating driveshaft.
• Cutting mechanism: The cutting mechanism of a disc drum mower consists of a set of rotating discs or drums that are equipped with cutting knives. These discs or drums spin rapidly when the PTO is engaged, creating a cutting action.
• Ground contact and movement: The mower is lowered to the desired cutting height using hydraulic or mechanical controls. The weight of the mower and the downward pressure exerted by the tractor's hydraulic system ensure good ground contact for effective cutting.
• Cutting action: As the tractor moves forward, the rotating discs or drums cut the vegetation in their path. The cutting knives mounted on the discs or drums make clean, precise cuts, and the cut vegetation is discharged to the side or rear of the mower.

Installation Guide for 3 Point Hitch Disc Drum Mower

Installation of a 3-point hitch disc drum mower to a tractor is a multi-step process that involves:

• Positioning the Tractor and Mower: Position the tractor on a flat, stable surface and align the mower so that its 3-point hitch arms are close to the tractor's hitch points.
• Attaching the Mower to the Tractor: Lower the tractor's 3-point hitch to easily align the hitch arms with the mower's mounting points. Attach the lower hitch points to the tractor's lower arms and the top link to the mower's top hitch point. Adjust the length of the top link to ensure the mower will be level with the ground once lifted.
• Connecting the PTO Shaft: Slide the PTO shaft of the mower onto the tractor's PTO stub, ensuring the locking pins engage securely. Adjust the shaft length if necessary and ensure there is enough clearance for the PTO shaft to move as the tractor and mower articulate over uneven terrain.
• Inspecting All Connections: Double-check all hitch points and the PTO connection to ensure they are secure. Lift the mower using the tractor's 3-point hitch and verify that it moves freely and that there is adequate clearance between the mower and the tractor.
• Testing the Mower: Start the tractor's engine and engage the PTO at a low speed to observe the mower's operation. Make any necessary adjustments based on the mower's performance during the test.

Common Troubleshooting Tips for Disc Rotary Mower

Troubleshooting common issues with a 3-point hitch disc or drum mower is crucial for its optimal performance. Here are some common problems and their solutions:

• Mower Won't Lift: This could be due to hydraulic issues in the tractor, incorrect hitch connection, or a malfunctioning hydraulic lift system. Check the tractor's hydraulic fluid level and refill if necessary. Ensure the 3-point hitch is correctly connected and inspect the hydraulic lift system for leaks or damage and repair as required.
• Uneven Cutting: This could be due to dull or damaged blades, incorrect cutting height adjustment, mower not level, or uneven ground. Sharpen or replace the blades, adjust the cutting height and ensure the mower is level by adjusting the top link or side links of the 3-point hitch. Mow at a speed suitable for the terrain to avoid scalping on uneven ground.
• Mower Vibrates Excessively: This could be due to unbalanced or damaged blades, loose hardware, damaged PTO shaft, or misaligned mower. Check and balance or replace blades, tighten any loose nuts, bolts, and other hardware, inspect the PTO shaft for damage or misalignment and repair or replace it as required.
• PTO Shaft Problems: The PTO shaft could be too long or too short, not properly secured, or have damaged universal joints. Adjust the PTO shaft length according to the tractor and mower manual instructions, ensure the PTO shaft is properly secured before use, and inspect and replace damaged universal joints or the entire PTO shaft if necessary.
• Mower Doesn't Discharge Cuttings Properly: This could be due to a clogged discharge chute, high moisture content in the grass, or cutting speed too fast. Clear any debris from the discharge chute, wait for drier conditions or reduce the mower's speed to allow for proper discharge of cuttings if the grass is wet.



• Difficulty Attaching or Detaching the Mower: This could be due to misalignment of hitch points, bent or damaged hitch pins, or insufficient clearance. Ensure that the tractor and mower are on level ground when attaching or detaching, check and straighten or replace any bent or damaged hitch pins, and adjust the tractor's hydraulic lift or move the mower manually to align hitch points correctly.
