Hay quality is a race against two things simultaneously: moisture level and weather probability. The faster cut forage dries to baling moisture \u2014 and the faster a rastrillo de heno<\/strong> can accomplish that (14\u201318% for dry hay, 45\u201360% for haylage), the fewer weather exposure events it faces during the critical drying window. A rastrillo de heno<\/strong> does not simply speed up drying as a convenience \u2014 it compresses the weather-exposure window by 30 to 40 percent, which directly translates to fewer rain events, fewer dew cycles, and fewer oxidative losses per cutting.<\/p>\n <\/p>\n El 9FZ-2.0 hay tedder<\/strong> mounts to the tractor’s rear three-point hitch Category I or II. The hydraulic fold uses one rear SCV outlet \u2014 no PTO shaft connection required. Tractor HP of \u226525.73 kW (\u224835 HP) ensures adequate drawbar pull at working speed and stable three-point hitch control during transport.<\/p>\n <\/p>\n The 30 to 40 percent drying time improvement of a finger wheel hay tedder<\/strong> over untreated hay is not simply a product of “turning it over.” The mechanism by which tine-disc tedders accelerate drying is more specific: it involves simultaneous swath inversion, mechanical swath expansion, and plant-stem fracturing at the nodes \u2014 three drying mechanisms that act in combination.<\/p>\n El 9FZ-2.0 hay tedder<\/strong>‘s three discs are each 1,500 mm (59.1 inches) in diameter. At this diameter, the 40 tines on each disc sweep the crop at a relatively shallow entry angle \u2014 approximately 15 to 22 degrees relative to the soil surface at standard working height. This shallow angle is mechanically significant: the tines slide under the hay mat rather than driving into it from above, which lifts the entire swath uniformly rather than creating patches of overtedded (shattered leaf) and undertedded (still-matted) material within the same pass.<\/p>\n Smaller-diameter discs at the same tine count produce a steeper entry angle, which increases the proportion of hay that is struck and thrown rather than lifted and turned. For legume hays (alfalfa, clover) where leaf shatter during tedding directly reduces protein content and therefore hay value, the shallow-entry geometry of a large-diameter disc is agronomically preferable \u2014 it moves more material with less impact force per tine contact.<\/p>\n Each of the three discs on this rastrillo de heno<\/strong> carries 40 spring-steel tines in two rows of 20, staggered to ensure continuous tine contact across the full disc rotation rather than gapped pulses. At 7 to 10 km\/h working speed, the 120 total tines across the three discs process the full 2.0-meter swath with approximately 160 to 230 tine contacts per square meter of hay mat \u2014 enough density to lift and aerate effectively without the redundant overlapping contacts that cause excessive leaf shatter at higher tine counts.<\/p>\n The spring-steel tine construction is critical for a second reason beyond lifting: as each tine runs through the hay stem, it creates micro-fractures along the stem wall at the leaf node positions. These fractures accelerate moisture loss from the stem interior \u2014 which dries substantially more slowly than the leaf surface \u2014 by providing additional escape pathways for internal moisture vapor. This stem-fracture mechanism is why tedded alfalfa dries more evenly across the full stem cross-section rather than producing the characteristic “dry leaf, wet stem” profile of untedded hay.<\/p>\n El 9FZ-2.0<\/strong> discs are ground-driven \u2014 disc rotation is powered by ground contact through the disc’s peripheral tines, not by a PTO shaft. This means: no PTO shaft connection needed, no risk of PTO overload events, and \u2014 most practically \u2014 the tractor’s rear PTO remains completely free for other implements during the same field session. The tractor’s 35 HP requirement is for drawbar pull at 7 to 10 km\/h working speed and three-point hitch load bearing \u2014 not for PTO power generation.<\/p>\n Ground-driven rotation also means that tine contact intensity scales directly with ground speed. At 7 km\/h, the tines make more rotations per meter of travel \u2014 more contacts, more intensive fluffing, suitable for dense alfalfa mats. At 10 km\/h, fewer rotations per meter \u2014 lighter treatment, appropriate for thin grass hay where aggressive tedding would shatter stems without benefit. The operator controls tedding intensity with the throttle and ground speed selector, without adjusting any mechanical setting on the implement.<\/p>\n <\/p>\n On a 100-acre operation with multiple small fields separated by county roads and farm lanes, the time spent transitioning between fields adds up across a cutting season. A manual fold mechanism requires dismounting, unbolting, repositioning, and re-bolting \u2014 typically 8 to 15 minutes per fold event. Hydraulic fold at the SCV lever from the cab takes under 2 minutes and requires no dismounting. On a cutting day with 4 to 6 field moves, that difference is 30 to 50 minutes recovered per cutting day, every cutting season.<\/p>\n<\/div>\n <\/p>\n Knowing when to run the rastrillo de heno<\/strong> \u2014 and when not to \u2014 determines whether the 30 to 40 percent drying benefit is actually realized. The most common finger wheel tedder<\/strong> timing errors are: tedding too early at excessive moisture (above 70%), which causes more leaf shatter loss than drying benefit; and not tedding at all on sunny days above 25\u00b0C because “it will dry anyway,” which wastes the weather window by accepting a slower natural drying rate when the machine could accelerate it.<\/p>\n <\/p>\n A rastrillo de heno<\/strong> is the second step in a four-step hay-making sequence. Its position in the chain is often skipped on small operations where every extra field pass seems like additional cost \u2014 but the pass it enables (a 1-day reduction in field time) typically recovers that cost in improved hay grade on every cutting where weather poses any threat.<\/p>\n <\/p>\n
