In cooler climates, the most common types are the disc harrow, the chain harrow, the tine harrow or spike harrow and the spring tine harrow. Chain harrows are often used for lighter work, such as leveling the tilth or covering the seed, while disc harrows are typically used for heavy work, such as following ploughing to break up the sod.
Harrows, whether spring tooth, spike tooth or disc harrows can have a drag connection or have a 3 point mounting. A drag harrow is pulled and cannot be backed up. Three point implements can be raised and lowered hydraulicly and maneuvered more easily. A spring-tooth harrow is a type of harrow, and specifically a type of tine harrow. It uses ...
A 4-foot drag harrow A larger, 12 foot drag harrow simply uses three four foot sections that are connected. A drag harrow, a type of spring-tooth harrow, is a largely outdated type of soil cultivation implement that is used to smooth the ground as well as loosen it after it has been plowed and packed.
Spike mauls are akin to sledge hammers, typically weighing from 8 to 12 pounds (4 to 5 kg) with handles 30 to 36 inches (80 to 90 cm) long. They have elongated double faced hardened steel heads. The head is typically over 12 inches (30 cm) long to allow the user to drive spikes on the opposite side of the rail without breaking the handle.
Spring spikes or elastic rail spikes [25] are used with flat-bottomed rail, baseplates and wooden sleepers. The spring spike holds the rail down and prevents tipping and also secures the baseplate to the sleeper. [26] The Macbeth spike (trade name) is a two-pronged U-shaped staple-like spike bent so that it appears M-shaped when viewed from the ...
A disc harrow is the preferred method of incorporating both agricultural lime (either dolomitic or calcitic lime) and agricultural gypsum, and disc harrowing achieves a 50/50 mix with the soil when set correctly, thereby reducing acid saturation in the top soil and so promoting strong, healthy root development.
Spike pullers are self-propelled by a diesel engine and travel along the railroad tracks. A typical spike puller is a small, two axle machine. Most spike pullers are designed only to remove spikes on one side of the tracks, meaning that two machines must be used together to remove all the spikes from both rails.
A peavey or peavey hook is similar but has a spike in the working end. [1] Many lumberjacks use the terms interchangeably. A peavey is generally from 30 to 60 inches (0.76 to 1.52 metres) long. The spike is rammed into a log, then a hook (at the end of an arm attached to a pivot a short distance up the handle) grabs the log at a second place.
