Checking and Adjusting the Cutting Unit Note: After extended running, a ridge will eventually develop at both ends of the bedknife. Round off or file these notches flush with the cutting edge of the bedknife to ensure smooth operation. The dual knob bedknife-to-reel adjustment system incorporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing performance.
Maintenance Lubricating the Machine Regularly lubricate the 5 grease fittings of each cutting unit (Figure 22) with No. 2 lithium grease. There are 2 lubrication points on the front roller, 2 on the rear roller, and 1 at the reel-motor spline. Note: Lubricating the cutting units immediately after washing helps purge water out of the bearings and increases bearing life. 1. Wipe each grease fitting with a clean rag. 2.
Servicing the Bedknife The bedknife service limits are listed in the following chart. Important: Operating the cutting unit with the bedknife below the service limit may result in poor after-cut appearance and reduce the structural integrity of the bedknife for impacts.
