- 8. What Digging and Grading Hand Tools are Available and How are They Used? Discuss the types of digging and grading tools and their use.
- 9. Tools Early man created hand tools from stone, metal, and wood to simplify their work. Hand tools make our tasks much easier to accomplish. Learning to use the right tool for the job and using it correctly reduces frustration and increases the work that can be completed. A starting point is to learn to identify the tools that will be helpful in horticulture.
- 10. Shovels Versatile tools used for digging and scooping. Use a shovel to dig out areas and clean loose soil from planting holes. Round point shovels are shovels with rounded sides coming to a point. – They are better for digging especially a hole or into piles of landscape rock than are square point shovels. Square point shovels have straight sides with a square end. – They are designed to level off areas and to square off the bottom of digging areas.
- 11. Shovels Cont. Spades have shorter handles with narrower and flatter shapes than shovels. – They are designed to penetrate the soil but have less scooping and carrying capacity than shovels. – Use spades for digging holes, cultivating, edging, and for breaking up soil. – They are useful in planting small shrubs and trees.
- 12. Shovels Cont. Hand spades (trowels) have a short handle and are more pointed than a spade. – They are used in digging holes to plant flowers and vegetables. Scoops are generally flat with high sides and work well for moving materials such as peat moss, sand, and crushed stone. – They are not intended for digging purposes.
- 13. Garden Hoes Tools used for hand cultivation and grading. A garden hoe is rectangular with only the bottom edge of the blade sharpened. – It is used to break up the soil prior to planting and to loosen soil and remove weeds in planted areas.
- 14. Hoes Cont. A weeding hoe consists of two sharp prongs located on top of a sharpened blade. – The sharp prongs are effective for pulling weeds while the bottom edge is used as a regular hoe. – Use a weeding hoe for cultivating hard, stony soil.
- 15. Hoes Cont. A grading hoe is a hoe with a narrow, sharpened, and flat end. – It is particularly helpful in loosening hard or compacted soil. A grubbing hoe has two narrow, sharpened and flat ends. – Use a grubbing hoe to loosen compacted soil or to dig up shrubs.
- 16. Forks A spading fork is a tool with four heavy tines or prongs used instead of a spade for turning over the soil when it is not too hard or compacted. – When digging trees bare root, or lifting clumps of bulbs or herbaceous perennials, the use of a spading fork reduces possible damage to the bulbs, tubers, rhizomes, or roots. A pitchfork is a lightweight fork for moving coarse, lightweight materials such as straw and compost. – It is not strong enough for digging soil.
- 17. Rakes Leaf rakes are used for raking grass clippings and leaves. Metal garden rakes are used for heavy duty raking, leveling, and grading. – They are often used in smoothing seedbeds prior to planting.
- 18. Rakes Cont. Grading rakes are lightweight magnesium rakes usually 42 inches wide. – They are used for smoothing and grading prior to seeding a lawn and for lightly raking in the seed after it is sown. A thatch rake has metal blades and is used to remove thatch (clippings and dead grass) built up in a lawn.
- 19. What Pruning and Cutting Tools are Available and How are They Used? Explain the major types of pruning and cutting hand tools and their use.
- 20. Pruning Tools Anvil hand pruners are a hand held pruner usually six to eight inches long with a sharp top blade that closes onto the anvil-shaped surface of the bottom blade. An S blade hand pruner cuts like a pair of scissors with one blade passing by the other blade to cut the wood.
- 21. Pruning Tools Cont. Lopping shears (loppers) are long handled (18 to 24 inches), heavy-duty pruners used for cutting limbs up to 1 ½to 2inches in diameter. – The bottom blade is curved to help hold the limb while the top cutting blade cuts through the wood.
- 22. Pruning Tools Cont. A pole pruner is basically a lopper on a pole. – The jaws are closed by pulling a rope. – The pole comes in sections four to six feet long. – Branches as high as 16 feet in the air can be cut while you stand on the ground.
- 23. Pruning Tools Cont. Hedge shears have 8 to 10 inch blades with handles to match. – The shears work like a large pair of scissors with both blades being sharp. – These shears are used for pruning landscape hedges and shrubs with young, tender growth. Grass shears are a small version of the hedge shears. – They are operated with one hand and designed to trim grass near landscape beds.
- 24. Pruning Tools Cont. A bow saw is a pruning saw with four to five teeth/inch made to cut on the draw (pull) stroke. – It is designed to be used to cut medium- sized branches. A curved blade pruning saw has a curved blade with 4 to 5 teeth/inch that cut on the draw stroke. – This saw is designed to prune large branches.
- 25. Pruning Tools/Knives Pruning knives are curved blade knives with a long wooden handle. – They are used for removal of undesired stems and small branches. Grafting knives are 3 to 4 inches long with smooth, sharp edges designed for accurate cutting. – The accurate cutting is important to achieve a proper match of the graft shoot with the rootstock.
- 26. Pruning Tools/Knives Cont. The pecan budding knife is a specially designed knife with two parallel blades set about one inch apart. – This design allows for the precise removal of the bud shield from one tree and the bark of the other tree. – Budding is simplified with the use of this knife. A patch budding knife is a specially designed cutter for the removal of a ½ by1-inch rectangular patch bud from one tree and the same size patch area on another tree to be budded.

- 28. How are Miscellaneous Tools Used in Horticulture? Describe the types and uses of miscellaneous hand tools in horticulture.
- 29. Spreaders and Sprayers Hand crank spreaders are used for small surface areas where power spreaders cannot be used. – The canvass hopper contains the seeds or fertilizer, which is broadcast by turning the hand crank. Broadcast spreaders have wheel- driven gears, which turn a propeller and throw or distribute the seeds or fertilizer to a width of 8 to 12 feet.
- 30. Spreaders and Sprayers Cont. Drop spreaders have a tined roller in the hopper that is wheel-driven. – Since the material is dropped directly under the hopper, the spread width is equal to the width of the hopper. Pump up sprayers are one to three gallon sprayers that use air pressure created by hand pumping.
- 31. Spreaders and Sprayers Cont. Backpack sprayers are similar to the pump up sprayers except the pressure can be built up by pumping while the sprayer is on your back and while you are spraying. – Large areas can be sprayed faster with this sprayer.

- 35. Carts and Wheelbarrows Lawn/utility carts and wheelbarrows are used to move soil, soil amendments (sand, peat, moss, etc.), and mulch (shredded bark, wood chips, landscape rock, etc.). Lawn/utility carts are flat bottom carts with two wheels.
- 36. Carts and Wheelbarrows Cont. Wheelbarrows typically have one pneumatic (air filled) tire with a four to six cubic feet capacity in a metal or plastic container. – Larger wheelbarrows are now available with two wheels providing more stability for the heavier load.

- 38. Lawn Roller Round cylinder filled with water or sand that can be pulled over loose soil to firm it. A common use is after seeding a lawn. Rollers pulled by a riding lawn mower are often used on an established lawn in the early spring.
- 40. Measuring Wheel Allows one person to measure distances. Areas need to be measured to estimate purchases of seed, fertilizer, mulch, etc. Some wheels measure feet and inches while others require you to multiply the number of revolutions of the wheel times its diameter to figure the distance.
- 42. What are the Common Hand Tools That are Useful in Horticulture? Discuss common hand tools used in horticulture.
- 43. Common Tools Common shop hand tools are useful in horticulture. Have on hand hammers, wood chisels, cold chisels, files, pliers (diagonal side cutting pliers, needle nose pliers, and combination pliers), standard screwdrivers, Phillips screwdrivers, adjustable wrenches, vise grips, channel locks, and a tape measures. These tools may be used to help with tool maintenance and repairs.
- 44. Common Tools
- 45. How Should Hand Tools be Maintained to Extend Their Life and Maximize Their Effectiveness? Explain how to maintain hand tools.
- 46. Maintaining Hand Tools Clean any soil or other debris from tools. Check tool for dull or bent blades. Straighten bent blades in a shop vise. Use steel wool or a wire brush to remove rust. Use a flat file to sharpen the cutting edge.
- 47. Maintaining Hand Tools Cont. Inspect the handle for cracks and breaks. If the handle passes inspection, use a shop rag to rub linseed oil into the wood. Replace a damaged handle or replace the tool. Store the tools inside. Organize your tools so you know where to find them.
