Similarly, check the reel blades for nicks, dents, or bends. Any imperfections in either the bedknife or the reel will negatively impact the cutting performance and may require grinding or replacement.

The goal is to achieve a light, consistent contact between the bedknife and the reel blades without excessive pressure. This "kissing" action ensures a clean shear of the grass blade. To adjust the bedknife, typically you'll find adjustment screws or bolts located on the bedknife frame. Tightening these adjusters moves the bedknife closer to the reel, while loosening them moves it further away. Make small adjustments and rotate the reel by hand to check for even contact across the entire width of the bedknife. Listen for a slight, consistent whirring sound, indicating proper contact. Avoid over-tightening, as this will cause excessive wear on both the bedknife and the reel and will also increase the power required to operate the cutting unit.

After adjusting the bedknife, perform a paper test to verify proper contact. Insert a thin piece of paper between the bedknife and the reel and rotate the reel by hand. The paper should be cleanly sliced along its entire length. If the paper tears or folds, the bedknife needs further adjustment. Repeat the adjustment and paper test until a clean cut is achieved. Finally, lubricate the bedknife with a light oil or lubricant to reduce friction and prevent rust. Remember to consult the John Deere 2500B's technical manual for specific torque specifications for the bedknife adjustment screws.

Grinding and Sharpening Reels

Over time, reel blades will inevitably dull and lose their sharpness due to constant contact with grass and soil. Regular grinding and sharpening are essential for maintaining optimal cutting performance. There are two primary types of grinding: relief grinding and spin grinding. Relief grinding creates a defined relief angle on the back side of the reel blades, reducing friction and improving cutting efficiency. Spin grinding, on the other hand, sharpens the leading edge of the reel blades without creating a relief angle. The choice between the two methods depends on the condition of the reel and the desired cutting performance.

Before grinding, thoroughly clean the reel and inspect it for any signs of damage, such as cracks, bends, or excessive wear. Any significant damage should be addressed before grinding to prevent further complications. When relief grinding, use a specialized relief grinding machine that is designed to maintain the correct angle and profile of the reel blades. Follow the manufacturer's instructions carefully and always wear appropriate safety gear, including eye protection and a respirator. After relief grinding, it's essential to balance the reel to prevent vibration and ensure smooth operation.

Spin grinding can be performed using a handheld grinder or a dedicated spin grinding machine. Again, wear appropriate safety gear and follow the manufacturer's instructions. Focus on sharpening the leading edge of the reel blades, being careful not to overheat the metal, which can weaken the blade. After spin grinding, deburr the edges of the reel blades with a fine grit stone to remove any sharp edges or burrs. Regularly inspect the reel for wear and tear and adjust your grinding schedule accordingly to maintain optimal cutting performance. Improper grinding techniques can damage the reel and shorten its lifespan, so it's always best to consult with a qualified technician if you're unsure about the proper procedures.

Backlapping Procedures
