9LZY-9.0 Rake Jerami Roda Jari | V-Rake 15 Roda 9m

Where the 9LZY-9.0 Sits in Our Finger Wheel Rake Family

Most penggaruk jerami buyers start the selection process at the wrong place — they look at specs first, rather than identifying which machine class the operation actually needs. The three-model comparison below starts that conversation correctly: 9 meters wide is available in two configurations (15 or 17 discs), and choosing between these finger wheel hay rake options is not about spending more for better but about matching disc density to actual field conditions.

Spesifikasi Teknis

All values are factory-rated. The 9LZY-9.0 hay rake requires only a drawbar hitch and standard tractor hydraulics for lift/lower control. No PTO shaft required — all 15 discs spin from ground contact. No electrical harness beyond optional lighting.

Commercial Capacity Planning: Annual Program vs Machine Hours

Understanding how the 9LZY-9.0 finger wheel rake's productivity spec translates into your actual annual program — total machine hours per year, days per cutting, working days needed across the full season — is what converts a specification sheet into an operational decision. The table below uses a conservative 7.5 ha/hr mid-range rate (between the 7.2 minimum and 9.0 peak) to give realistic planning numbers.

V-Rake Windrow Geometry: Why the V-Configuration Produces a Better Windrow Than Side-Delivery Rakes

Itu 9LZY-9.0 hay rake is a V-rake — the two banks of discs are angled in a V-pattern, with the open end facing forward and the discharge point of the V centered behind the machine. Both disc banks sweep inward toward the center, depositing hay into a single, centered windrow along the machine's track. This geometry differs fundamentally from side-delivery rakes (which deposit the windrow to one side) in three ways that matter for downstream baling efficiency.

Disc Spacing and Forage Density: Why 600 mm Spacing Is the Right Spec for Most Operations

Itu 9LZY-9.0 hay rake's 15 discs across 9.0 meters of working width produce an average disc-to-disc center spacing of approximately 600 mm. This spacing is not arbitrary — it represents the design optimum for the forage density range that the large majority of commercial U.S. hay operations produce: 3 to 6 tonnes of dry matter per hectare per cutting on alfalfa, and 2 to 4 tonnes on commercial grass programs.

The 600 mm disc spacing means that each disc is responsible for a 600 mm column of cut forage as the machine passes. At typical commercial hay densities (3 to 5 t/ha dry matter), this column contains approximately 180 to 300 grams of dry crop material per meter of forward travel — a volume that the 60-tine disc handles cleanly without the tines bridging over dense mat sections or allowing material to pass between discs untouched. At forage densities above 6 to 8 t/ha (the upper end of exceptional-yield irrigated alfalfa first cuttings), the 600 mm spacing approaches its practical limit — which is precisely where the 17-disc 9LZD-9.0's 530 mm spacing provides measurable benefit.

How It Works: Ground-Driven Finger-Disc Raking Explained

Itu 9LZY-9.0 finger wheel rake operates on a fully mechanical principle with no PTO connection at any point in the operating cycle. The physics of the system are straightforward but worth understanding, because they directly explain both the machine's performance characteristics and its maintenance simplicity.

Ground Contact and Free-Spinning Rotation

Each of the 15 discs is mounted on a free-spinning hub bearing. As the tractor moves forward, the curved spring tines on each disc contact the stubble surface and crop residue simultaneously. The friction between the tine tips and the ground/crop generates a torque reaction that causes each disc to rotate freely on its bearing. The faster the tractor moves, the faster each disc rotates — ground speed directly controls tine contact frequency at any given point in the hay mat.

This ground-speed-driven rotation means the operator controls raking intensity simply by adjusting ground speed — no mechanical adjustment to the implement is required. Light crop at 12 km/h produces rapid disc rotation with light tine pressure. Dense mat at 8 km/h produces slower disc rotation with heavier tine engagement per rotation. The spring-steel tine construction absorbs impact from ground irregularities, rocks, and hard-pan sections through elastic deflection — each tine bends under impact rather than transmitting the load rigidly to the hub bearing, which dramatically reduces bearing fatigue under commercial-scale annual operating hours.

Lateral Crop Flow and Windrow Formation

Each disc is mounted at a fixed angle (typically 15 to 20 degrees) relative to the machine's direction of travel. This angle creates a lateral velocity component in the rotating tines: as each tine lifts the forage material, it imparts a sideways motion that carries the crop toward the windrow discharge center. The magnitude of the lateral velocity depends on the disc angle and the disc rotation speed — both of which are set by the manufacturer's engineering parameters, not by operator adjustment on this machine.

On the 9LZY-9.0 V-configuration, the left bank of discs is angled to sweep material to the right-center, and the right bank sweeps to the left-center. Both streams converge at the machine's centerline, producing the single centered windrow. The windrow width (0.8 to 1.2 m) is controlled by the exact disc angle and the degree of material overlap between the two banks at the center point — parameters set during factory assembly. Field windrow width is primarily adjusted by raising or lowering the machine's working height via the tractor's drawbar hitch height setting, which changes the effective tine contact angle on the ground.

Matching Your Windrow to Your Baler's Pickup Width

Itu 9LZY-9.0 hay rake's 0.8 to 1.2 m windrow width output is designed to match the standard pickup header width on the jajaran mesin pengepak jerami bundar — specifically the 1.4 m and 1.6 m wide spring-tine pickup headers used on commercial mid-range and large balers. Getting the windrow-to-baler width relationship right is one of the most directly impactful operational decisions in the hay-making chain. An undersized windrow relative to baler pickup width produces bales with low-density outer edges; an oversized windrow causes pickup bridging at the header sides.

For the 9YG-2.24D commercial baler, the standard operating procedure is to run the 9LZY-9.0 at 9 m working width in a parallel pattern, then make a merging pass with the rake at half-width displacement — or run a dedicated tedder on the first day and the rake on the second day as a heavier merged windrow. The same peralatan pemotong rumput layout that produces the cut-crop pattern also determines how many rake passes are needed to build the baler-compatible windrow for each machine class.

The round baler that processes the windrow downstream operates a 540 rpm PTO driveline on its pickup and bale chamber mechanism. A correctly spec'd gearbox penggerak pertanian in the baler's PTO circuit handles the sustained compaction loads and pickup surge events that occur when a well-formed dense windrow from the 9LZY-9.0 enters the chamber at full ground speed.
