SECTION I INTRODUCTION AND DESCRIPTION Drivetrain consists of a triangular, telescoping input driveshaft, 90 degree transfer gearbox, hexagon cross-shaft and a chain driven rotor. Protection is provided by an in-line shear bolt or slip clutch on the driveline. The chain is self-adjusted by a spring tension device. Major components of the tiller are identified in Figure 1-1 and specifications are given in Table 1-1. 1-2 INTRODUCTION We are pleased to have you as a Bush Hog customer.
SECTION II PREPARATION FOR USE NOTE If driveline is correct length, omit the following steps “G” through “J” and proceed to step “K”. G. Clamp driveline in a padded vice to prevent damage to shield. Cut of shield where marked. (Figure 2-3) 2-1 ATTACHING TO TRACTOR WARNING TO AVOID SERIOUS INJURY OR DEATH: NEVER STAND BETWEEN TRACTOR AND TILLER WHILE TRACTOR IS BEING BACKED TO HITCH.
H. Using cut off section of shield as a guide, cut shaft the same amount. (Figure 2-4) 2-2 OFFSETTING TILLER Figure 2-4 The tillers may be offset to the right up to 6 inches on Model RTS40, 12 inches on Models RTS50 and RTS60, and 18-1/4 inches on Model RTS74. Adjust as follows: A. Loosen U-bolts securing hitch lugs and gearbox stand to tiller frame. B. Slide hitch lugs and gearbox to desired position maintaining the distance shown in Figure 2-6.
SECTION III OPERATING INSTRUCTIONS Depth of till is regulated by moving adjusting bolt and adjusting skids up or down. (Figure 3-1) The holes in the adjusting plate are in 1 inch increments with the bottom hole being a 4 inch tilling depth. Average soil with reasonable moisture will allow depth of 4 inches in one pass with a tractor forward speed of 2 mph. Heavy or packed soil may require two passes to reach 4 inch depth. Using multiple passes, a maximum depth of 7 inches may be obtained.
3-3 OPERATION E. Place tractor in gear and proceed forward. Increase speed to 3/4 throttle. Lower tiller into soil. Increase speed to 540 PTO rpm. Average soil with reasonable moisture will allow travel speeds up to 2 mph. Hard soil will require low travel speed, less than 1 mph to ensure smooth operation and maximum possible depth. Shallow weed cultivation will allow speeds up to 3 mph. At the end of a pass lift tiller clear of ground before making a turn.
4-2 LUBRICATION (Figure 4-1) 4. Input Gearbox - Add EP80W-90 gear oil, if necessary, to bring oil level to check plug.
