OPERATION SECTION Operation Section 4-1
OPERATION The Rhino Disc Mower requires 540 RPM PTO power and is designed to mount on Category II 3-point hitch equipped tractors. Model DM82 mowers require a minimum of 40 HP for operation. Model DM95 mowers require a minimum of 45 HP. Model DM112 mowers require a minimum of 50 HP. Model DM124 mowers require a minumum of 60 HP. Connecting the Mower to the Tractor 1. Connect the 3-point frame to the lower links of the tractor and secure with klick pins.
OPERATION 6. Lower the mower so that the center of the lower linkage arm is 16" above the ground. (See Figure 5.) 7. Connect the Support chain (S) to the tractor's top link support bracket and adjust to maintain the ground-tolinkage height of 16" set in Step in 5. Plate attaches on righthand lower lift arm pin. Chain should maintain mower height, adjust as necessary. 8. Lower the mower to the ground and check the following: A. Cutter bar contact with the ground. B. Proper chain tension. C.
OPERATION IID Shaft Installation Adjusting Shaft Length (Con't) 4. Cut the shield and shaft of the mower half so the same amount is removed as the tractor half. Deburr the ends, lubricate the shaft halves with grease and reassemble the halves. 5. Install the IID shaft on the tractor and mower. Raise and lower the mower to check for shaft contact (bottoming-out) with the mower yoke end. At the maximum compressed point, the shaft should look like Figure 9.
OPERATION Adjusting Mowing Height The mowing height is adjusted by adjusting the top link of the 3-point linkage to move the forward portion of the disc up or down. (See Figure 11.) IMPORTANT: Do not allow the disc blade to contact the ground. On uneven ground, raise the blade tip by tilting the cutter rearward. Tipping the cutter too far rearward, over horizontal will result in premature blade wear. Cutting too close to the ground will cause excessive blade wear.
OPERATION BELT TENSION ADJUSTMENT The belt tension must be adjusted properly to prevent the belt from slipping. To adjust the belt tension, loosen the jam nut and tighten the nuts on the Tensioning Rod until each belt can be depressed 1/2" when a force of 11 pounds is applied to the belt at a point midway between the pulleys (See Figure 14). An Access Hole (V) is provided in the belt shield to check belt tension (See Figure 15).
OPERATION Swath Board The Swath Board (W) is located on the outer end of the cutter bar. The swath stick can be positioned at three settings to handle different crop conditions such as long, short or flattened crops. Remove the front bolt (Y), move the swath stick to the desired position and reinstall the bolt in the new hole. (See Figure 17.
OPERATION TRANSPORTING THE MOWER 1. Make sure the stand tube is secured in the "up" position. If not, pull clip and Pin (R) and slide Stand Tube (A) up. Secure with Pin (R) and clip. (See Figure 19.)
