Available Shaker Grids and Spare Parts

The shaker grids are essential filtering elements for optimal grain-straw separation. Our refurbished models include standard perforated grids and reinforced Graepel versions for heavy-duty use. Dimensions vary by brand: 30x40mm for John Deere series Z, while Claas Modern models feature specific perforations.

Wooden bearings are another key component of the shaking system. Their 25mm diameter guarantees smooth rotation of crankshafts across all references. The cock's crests and U-shaped supports complete our range of refurbished components, allowing a full restoration of your separation system.

Choosing Your Shaker According to Combine Brand

• Claas favors robust shakers with reinforced crankshafts, particularly suited for rough terrain.
• John Deere is characterized by a modular design facilitating preventive maintenance.
• Fendt employs variable amplitude technology to automatically adapt to throughput.
• New Holland favors high-speed systems optimized for large cereal farms.
• Massey Ferguson focuses on ease of maintenance with bearings accessible without full disassembly.
• Case IH distinguishes its models by self-cleaning grids reducing frequent blockages.
• Deutz-Fahr develops energy-efficient shakers to limit engine load.

Deutz Fahr and Laverda Shakers: Technical Specificities

Deutz-Fahr models incorporate automatic compensation systems that adjust amplitude based on terrain slope. This patented technology maintains constant separation even on uneven fields. The crankshafts undergo specialized heat treatment that extends their lifespan by 30% compared to market standards.

Laverda offers shakers equipped with self-lubricating bearings, drastically reducing maintenance interventions. Their perforated grids use a reinforced alloy resistant to abrasion, particularly suited for hard-stem cereals. The shaking frequency reaches 220 strokes per minute on recent models, optimizing the extraction of remaining grains.

New Holland Compatibility and Optimal Performance

• New Holland TX and CX feature variable speed shakers synchronized with forward speed.
• CR hybrid models combine conventional shakers and rotors to optimize field throughput.
• TC series includes shakers equipped with load sensors that automatically adjust amplitude.
• New Holland references use sealed bearings guaranteed for 2000 hours without preventive maintenance.
• The Twin Rotor system allows operation at 180 strokes per minute while preserving grain quality.
• New Holland sieves feature patented hexagonal perforation reducing losses by 15%.
• Upward compatibility permits fitting recent shakers on models before 2020.

The Role of the Shaker in Grain-Staw Separation

The shaker accomplishes its grain-straw separation task through a precise oscillatory motion that shakes the straw windrow. This mechanical action frees the remaining grains trapped in the ears after the passage of the threshing drum and concave. The ridges, resembling metal steps, create controlled agitation that moves straw backward while extracting the last grains by friction.

System efficiency relies on an optimal frequency of 150 to 200 strokes per minute with a 20° tilt. This rhythm generates enough jolts to detach stubborn grains without damaging their quality. The perforated grids beneath each shaker then filter the freed grains, which fall directly into the cleaning system.

A properly adjusted shaker processes about 10% of the harvest grains — those not passing through the concave during initial threshing. On a modern 6-shaker combine, this expanded separation surface ensures near-total grain recovery, limiting field losses to under 1%.

Reducing Grain Losses with a Suitable Shaker

• Check bearing wear every 500 hours to maintain constant shaking amplitude.
• Replace perforated grids as soon as holes widen beyond 12mm diameter.
• Inspect drive belt tension before each harvest campaign to avoid slippage.
• Adjust shaking speed according to moisture: 180 strokes/minute in dry conditions, 200 in wet.
• Monitor the condition of ridges as their deformation reduces mixing efficiency by 25%.
• Clean grids daily to prevent buildup of plant debris that obstructs flow.
• Install oversized shakers on farms exceeding 200 hectares annually to handle extra load.
