(Ref. 28). 2. Assemble flat bracket L.H. (Ref. 69) to the power input side of the gear case with two bolts 5/8—11 x 1-1/2” long (Ref. 67) and lockwashers 5/8 diameter (Ref. 25). 3. Assemble offset bracket R.H. (Ref. 68) to the right hand side of the gear case with two bolts 5/8-11 x 1-1/2” long (Ref. 67) and lockwashers 5/8 diameter (Ref. 25). 4. Assemble the universal drive shaft assembly (Ref. 26) to the gear case with spirol pin (Ref. 22). Drive pin into the shaft with a hammer. The end of the universal drive shaft assembly with the square head set screw attaches to the power take off on the tractor. 5. Assemble cover bracket (Ref. 5) to the cover assembly (Ref. l)with sixcarriage bolts 5/16—18x1” long (Ref. 4), lockwashers 5/16 diameter (Ref. 6) and nuts 5/16—18 thread (Ref. 7). Assemble bolts and nuts loose until all six are started, then tighten. 6. Assemble cover and bracket assembly to the gear case with four bolts 1/2—13 x 7/8 long (Ref. 9) and lockwashers 1/2 diameter (Ref. 10). Assemble bolts loose until all four are started, then tighten. 7. Remove the solid pipe plug in the hole above the input shaft in the gear case and replace it with the vented pipe plug (Ref. 21). Refer to Figure 2 for proper location of the vented plug. This vented plug allows the gear case to breathe. 8. The lubricant level in the gear case should be checked after it is attached to the tractor. 2 ATTACHING YOUR ROTARY tlLLER TO YOUR TRACTOR (Models 193-966 and 193-967) 1. Before attaching your rotary tiller to your tractor, be sure the rear wheels on the tractor are all the way into the minimum rear wheel width. Refer to your tractor manual. 2. Remove the draw bar assembly from the three point hitch of your tractor by removing the two cotter-hairpins. 3. Place the rotary tiller behind the tractor in the approximate position shown in Fig. 2. 4. Attach universal drive shaft (Ref. 26) to the tractor power take off. Tighten set screw (Ref. 27). 5. Move the lift lever on the tractor until the draft bar assemblies line up with pivot brackets (Ref. 24). 6. Assemble pivot brackets (Ref. 24) to the rear of the tractor with washers and cotter-hairpins. ATTACHING YOUR ROTARY TILLER TO YOUR TRACTOR (Model 192-766). 1. Before attaching your rotary tiller to your tractor, be sure the rear wheels on the tractor are all the way into the minimum rear wheel width. Refer to your tractor manual. 2. Remove the “U” part of the plow hitch from your tractor by removing the two cotter-hairpins on the loose clevis pins and the two cotter-hairpins from the hitch adjusting rods. Refer to Fig. 1. 3. Adjust the hitch adjusting rods until 3 or 4 threads extend beyond the rear hitch ferrule. 4. Place the rotary tiller behind the tractor in the approximate position shown in Fig. 2. 5. Attach universal drive shaft (Ref. 26) to the tractor power take off. Tighten set screw (Ref. 27). 6. Assemble brackets (Ref. 68 & 69) to the rear of the tractor with the loose clevis pins, washers and cotter-hairpins. CHECK LUBRICANT LEVEL at this time. The gear case is lubricated at the factory but should be checked for proper lubricant level before each operation. Remove plug (Ref. 61) on side of gear case. Lubricant should be at this level, if not, fill through the vented pipe plug hole (Ref. 21) with SAE 140 oil until the lubricant overflows through the hole in the side of the gear case. Replace the pipe plugs. BE SURE THE VENTED PIPE PLUG IS IN THE OIL FILL HOLE. Refer to Fig. 3. Lift the rotary tiller with the lift h-adle on the tractor to transport it to and from the work area. Use caution when transporting the rotary tiller since your ground clearance has been reduced. The entire tiller unit is offset to the left to allow closer tilling with the left side. NOTE: BE SURE THE POWER TAKE OFF HANDLE IS IN THE “OFF” POSITION BEFORE STARTING THE TRACTOR ENGINE. Refer to the tractor manual for proper position of the PTO handle. GENERAL ROTARY TILLER OPERATION ALWAYS shut the engine off when removing a stone or anything that becomes entangled in the tines. All large stones or rocks should be removed from the area before you begin tilling. Tilling can be done with or without the outer tine assemblies. You can till 32^2?5 wide with the outer tines and 17” wide with only the inner tines. Use rear wheel weights when tilling. Part number 191-776. Maximum tilling depth is approximately 10” depending on the type of soil. This CANNOT be accomplished in one pass. Maximum tilling depth may be only 2-1/2” on extremely hard soil on the first pass. The more passes you make with the tiller over the same area, the deeper you can till and the finer you pulverize the soil. Change directions as often as you can to level out the ground and to prevent furrows. When tilling, the tiller will push the tractor and the transmission on the tractor will hold the tractor back. For easy lifting of the rotary tiller from the ground, shut off the power by disengaging ...
