The recommended PTO speed for optimal performance of the John Deere 1408 Rotary Cutter is 540 RPM.
To sharpen the blades, first disconnect the PTO shaft and remove the blades. Use a grinder to sharpen the cutting edge, maintaining the original angle. Reinstall the blades securely before use.
Use SAE 80W-90 gear oil for the gearbox to ensure proper lubrication and performance. Check the oil level regularly.
Grease all fittings every 8 hours of operation or daily when in heavy use to maintain optimal performance and longevity.
The cutting width of the John Deere 1408 Rotary Cutter is approximately 14 feet, allowing for efficient coverage of large areas.
Adjust the cutting height by changing the position of the skid shoes and the rear wheel assembly. Ensure both sides are adjusted equally for an even cut.
Excessive vibration can be caused by unbalanced blades or debris build-up. Check for damage or debris and ensure blades are balanced and securely attached.
To replace a belt, first disengage the PTO and remove any guards. Relieve tension on the belt and remove it from the pulleys. Install the new belt and adjust tension according to the manual.
Clean the cutter thoroughly, lubricate all moving parts, and store it in a dry, sheltered area. Disconnect the PTO shaft to prevent accidental engagement.
Always wear appropriate safety gear, ensure all shields are in place, and never allow bystanders near the operating area. Read the operator's manual for full safety instructions.
