Knife around sharpened so you can change quickly if you are caught in the middle of a mowing job That way you can keep a sharp Knife on your Sickle Mower and have a sharp Knife in reserve at all times To remove the Knife for sharpening remove the Knife Bracket Screws and slip the blade out either side WHEN YOU REPLACE THE BLADE ALWAYS BE SURE THESE SCREWS ARE TIGHT The Knife Sections should be ground at the same angle they were originally It is usually fairly easy to follow this angle Your Dealer has a hand Sickle Grinder that has a special grinding cone the right pitch for grinding the Knives or for a small charge he will sharpen your Knives for you ADJUSTING THE SWIVEL ACTION A very important feature of the Gravely Sickle Mower is the swivel action of the Cutter Bar This swivel action is adjusted by means of the two bolts on the upper towards the tractor part of the Crank Housing When these bolts are tight the Bar is held rigid When they are loosened the Bar will swivel and follow the contour of the ground The bolts should be adjusted tight enough so that the Bar will hold its position until lowered and loose enough so the Bar will tilt according to the slope or contour of the ground ADJUSTING THE GUARDS The Guards should always be kept in alignment If one Guard gets bent up and another down it will not cut fine grass Use a light hammer and knock the Guards up or down until the Knives on the Sickle lay fiat on t
5. Shank slips easily into place Move the Shank up or down until it meets your requirements then tighten the cap screw until the Shank is held firmly There are five Shank Holders already attached to the Cultivator in the proper positions These may be moved if desired although this is seldom necessary Additional Shank Holders may be purchased and attached to suit your needs if desired The Tools are divided into two classes those that require the One Hole shank and those that require the Two Hole Shank All Cultivating Tools except the Furrowers Hillers Shovel Steel and Turning Shovel require the One Hole Shank To attach to the Shanks simply bolt in place with the bolts and nuts provided Changing from one tool to another only requires the switching of the Tools on the Shanks unless you need a Two Hole Shank where you have a One Hole on the attachment In that case change the Shanks also ADJUSTMENTS Depth Wheels are part of the Cultivator whether used on the front or rear of the Tractor They are used to set the depth the cultivating tools penetrate the ground With the Depth Wheels toward you turning the Handwheel to the right will give deeper cultivation to the left shallower cultivation Usually the Depth Wheels are all the adjustment you need However if necessary you can adjust the Shanks in the Shank Holders up or down to meet your requirements PARALLEL BARS The Parallel Bars can be adjusted in several
6. adjustment of the Depth Wheel The cultivator will follow the contour of the ground closely and the last two steels shield foliage and vine crops so that they will not be bruised by the wheels PLATE 49 DISC HARROW The Rear Disc Harrow is used mostly for cultivation since the Gravely Rotary Plow gives a perfect seedbed without any type of harrowing or drag ging The Disc Harrow requires the Rear Hitch It is attached as shown An occasional squirt of Mobiloil on the Axle is the only lubrication required Pitch of the Discs is adjusted by releasing the Clamp Screw and adjusting the pitch of the discs to your requirements PLATE 51 FURROWERS are available in 10 or 12 inch sizes may be used front or rear to lay off rows for planting Many users also find it a good tool for digging potatoes For smaller furrows seven inch shovel steels are available These are very handy for laying off small seed crops and can be used for center row cultivation PLATE 52 1 Discharge Spout Clamp Wheel 2 Discharge Spout 3 Gear Housing 4 Pillow Block Screw remove this to lubricate Pillow Block Bearing SNOWBLOWER INSTRUCTIONS OPERATING INSTRUCTIONS GRAVELY SNOWBLOWER ATTACHMENT LUBRICATION On the Gear Housing of the Snowblower are two pipe plugs one large one small Remove both plugs Fill the Gear Housing through the large hole with Mobilube GX 90 until it begins to run out the small hole which is the oil level Avoid

8. different ways depending upon the task Usually it is necessary to disassemble the Parallel Bars from the Depth Wheels to make these different set ups OPERATING HINTS HOW TO CULTIVATE Cultivating depth and how close to plants to cultivate are individual problems and preferences However there are certain tips that may help you You can set the Shanks individually for example so your Cultivator will be going deep in the center and barely stirring the dirt next to the plants This will save a lot of hand hoeing and will not damage the plants when done with care Of course you must plant your rows wide enough to accommodate the Tractor when you intend to use the Cultivator The normal row width is about 32 36 inches Wider rows should be used for plants that spread widely unless you intend to shield the cultivator so you won t damage the plants Occasionally a User tells us that he is not getting good results in hard ground or very stony ground The Cultivator will have a tendency to bounce up when it hits an obstruction You can eliminate this very simply and inexpensively by filling a cloth or burlap bag with about 50 pounds of sand and laying it on the Toolholder This will hold the Toolholder down and does not make any appreciable difference in the handling of the Tractor Incidentally the Cultivator is very good for stirring deep litter in brooder houses REAR CULTIVATOR Many of our Users prefer the Rear Cultivator because w h
9. e n used on the rear of the Tractor the cultivator loosens the dirt previously packed down slightly by the wheels Set up of tools and adjustments for depth are the same as shown for the Front Cultivator Rear Hitch required PLATE 45 CULTIVATING TOOLS All Tools Used on the Same Toolholder PLATE 46 SWEEP AND HOE SET UP uses an improved Sweep in the center and a right and left Gravely Hoe on either side The Sweep may be obtained in 8 10 12 and 18 inch sizes The Sweep clears the center of weeds and trash and the special Gravely Hoes eliminate the majority of hand work close to the plants 5 PLATE 48 5 STEEL SET UP is the standard arrangement uses 11 4 steels Extra steels and shanks may be purchased The picture Plate 44 on page 19 shows the method of arrangement when seven steels are used Steels are available in 11 4 13 4 and 21 4 sizes All cultivating tools are used on the same toolholder are interchangeable PLATE 50 6 I N C H HILLER SET UP uses right and left hillers can be used for closing rows as well as hilling They throw dirt away from or around the plants as you desire You can use a furrower in the center at the same time bringing the dirt from the center of the row to the hillers which in turn heap it around the plants 20 PLATE 47 7 STEEL V SET UP uses one Depth Adjusting Wheel with the parallel bars arranged to form a V Depth is obtained by a single
