Agricultural Gearbox Manufacturer for Efficient Farming Solutions

Raydafon Agricultural Drive Systems

Agricultural Gearbox Manufacturer for Rotary Tillers, Mowers, Seeders and Feed Mixers

Raydafon builds agricultural gearboxes for the implements that actually do the work: rotary tillers, flail mowers, lawn mowers, fertilizer spreaders, seeders, TMR feed mixers and balers. Every unit is produced in our own factory, from housing casting and gear cutting through heat treatment, assembly and run-in testing, under an ISO 9001 quality system.

Buyers come to us with a tractor PTO rating, an implement drawing, a failed gearbox sample or just a working condition. We confirm the ratio, torque class, input/output interface and housing orientation, then manufacture against that specification.

Product Overview

What Raydafon Manufactures

Raydafon focuses on agricultural gear transmission systems. The current range covers lawn mower gearboxes, flail mower gearboxes (side-mounted grass shredder gearboxes), rotary tiller gearboxes, mower reducers and dedicated gearboxes for fertilizer and sowing machinery. Each housing shape, gear set and output flange is designed around a specific implement working condition rather than copied from a generic catalogue.

  • Compact housing, stable transmission — high-quality alloy steel helical or spur gears, low running noise, minimal vibration, longer mechanical life.
  • High torque output for harsh conditions — large module design with hardened tooth surfaces, suitable for heavy load, slippery, dusty ground: dense grass, forest edges, slopes and gravel.
  • Multiple mounting interfaces — standard PTO input (1-3/8" Z6 / Z21) with a range of output flange forms to suit different implement models.
  • Low maintenance design — optimised internal lubrication with oil level window and breather, reducing daily maintenance frequency.
  • Full customisation support — OEM and ODM service for ratio, mounting direction, input/output form and housing structure. Samples delivered in as fast as 15 days.

Raydafon agricultural gearbox range — housings cast and machined in-house, gear sets produced and heat-treated on site.

Raydafon products are widely used on small and medium tractors mounting agricultural implements, particularly on high-specification farm equipment for the European and American markets. Units are in service in Germany, Italy, the United States and Brazil with local brands and large OEMs. We supply single units as well as volume production and long-term supply agreements.

Alongside agricultural gearboxes, Raydafon manufactures precision transmission parts including plastic gears, bevel gears and screw gears for industrial automation, food machinery and medical equipment, so multiple supporting components can be sourced from one supplier.

Selection Guide

How to Choose an Agricultural Gearbox That Fits the Job

Price and appearance are the wrong starting points. What decides whether a gearbox lasts a season or a decade is how well it matches the implement, the tractor and the ground it works on. The four criteria below cover the questions our engineers ask on nearly every enquiry.

  1. Confirm the application type first Implement category drives the whole design. Lawn mower gearboxes need high-speed operation and impact resistance. Tiller and rotary tiller gearboxes emphasise torque output and structural strength. Seeders and sprayers use lighter structures with higher demands on transmission efficiency and maintenance convenience.
  2. Match the mounting and drive parameters Input speed and output ratio must match the tractor PTO. Input and output shaft diameter and connection type must be compatible with the existing PTO interface. Mounting hole spacing and installation direction must allow a clean fit to the implement frame. Rotation direction must be confirmed to avoid running the implement backwards.
  3. Check material and processing Quality agricultural gearboxes use ductile iron housings with internal gears in alloy steel such as 20CrMnTi, carburised and quenched for wear resistance. In dusty or muddy working conditions, the sealing structure must be specifically reinforced to stop lubricating oil leaking out and grit getting in.
  4. Verify torque carrying capacity Confirm the gearbox's maximum output torque against the actual implement load, especially in high-load operations such as deep tilling and heavy grass cutting. Heavy-duty gearboxes should be selected in preference to a lighter unit that will run hot and fail early.
  5. Consider serviceability Agricultural equipment works outdoors continuously. A gearbox with an oil level observation window and cleanly accessible oil drain port is significantly easier to maintain, and parts availability matters as much as the initial specification.

Performance Data

Maximum Torque and Speed Range of Raydafon Agricultural Gearboxes

Load-bearing capacity is the single factor that decides whether an implement survives a long season of high-load work. Raydafon has developed a series of gearboxes from light duty through to heavy duty, covering the full range of tractor-mounted implements. Every unit is load tested before it leaves the factory.

Output Torque Coverage

Light Series 100–300 N·m Sprayers, seeders and light-duty implements where weight and efficiency matter most.
Medium Series 500–900 N·m Mowers and rotary tillers working continuously across mixed field conditions.
Heavy-Duty Series Up to 1500 N·m Balers, fertilizer mixers and crushers running sustained high-load cycles.
Special Customised 2000+ N·m peak Extreme working conditions and complex environments requiring peak torque capability.
Standard PTO Input 540 / 1000 rpm Compatible with mainstream tractor PTO output interfaces worldwide.
High-Speed Custom Up to 2000 rpm For high-efficiency tractors and power machinery requiring faster input speeds.

Speed and Efficiency

Output speed depends on the selected reduction ratio, with output ranges covering from a few dozen up to several hundred rpm depending on model. Gears are ground to high precision with optimised tooth form to ensure smooth meshing at high speed, giving transmission efficiency above 96% and operating noise controlled below 72 dB.

Serviceability

Is the Agricultural Machinery Gearbox Easy to Disassemble and Repair?

In daily use, a gearbox eventually wears, leaks oil or develops an abnormal gear noise. What matters at that point is how quickly the unit can be opened, inspected and put back into service. Raydafon gearboxes are designed around that practical reality — compact overall, but straightforward to strip down and rebuild.

  • Modular design — input shaft, output shaft, gear set and housing are assembled from standardised parts. Conventional tools are enough for most disassembly and assembly work.
  • Simple shell and clear bolt layout — the housing is a symmetrical split cast iron structure with unobstructed, well-spaced bolts. Loosen them in sequence to open the cover and inspect internals.
  • High parts commonality — gears, oil seals and bearings are standard in size and highly interchangeable. Replacement parts are ordered by part number without custom manufacturing.
  • Documentation supplied — each gearbox ships with an exploded diagram and disassembly instructions covering part numbers, assembly sequence and precautions, for in-house repair or remote support from our technical team.
  • Recommended inspection interval — check oil seal wear after every 500 hours of operation, and inspect the gear meshing surface for abnormal wear or scoring. Timely treatment significantly extends service life.
Agricultural gearbox disassembly and maintenance
Modular construction with standardised internal parts keeps field service simple and replacement part costs predictable.

What we recommend for fleet operators

Keep one spare oil seal and bearing set per gearbox model in stock. On a 500-hour inspection cycle this turns a mid-season breakdown into a same-day repair, which is usually the difference between keeping a harvest window and losing it.

Buyer Questions

Agricultural Gearbox FAQs

What information do I need to send for a gearbox quotation?

Send the implement type, tractor PTO speed, required output speed or ratio, maximum working torque, input and output shaft dimensions, mounting hole spacing and installation direction. A drawing, sample photo or part number speeds up the confirmation considerably.

Can you build a gearbox to replace a specific brand?

Yes. We regularly produce replacement gearboxes matched to established models, including feed mixer gearboxes compatible with Comer and similar ranges. Send the original part number or a dimensioned drawing and we will confirm the match before production.

What is the sample lead time for a customised gearbox?

Customised samples are typically delivered in around 15 days, depending on housing complexity and gear cutting requirements. Volume production timing is confirmed along with the quotation.

How do you handle lubrication and maintenance requirements?

Every gearbox is supplied with an oil level window and breather. We recommend checking oil seal condition every 500 operating hours and inspecting the gear meshing surface for wear. Detailed maintenance instructions ship with each unit.

Do you supply other drivetrain components alongside the gearbox?

Yes. Raydafon also manufactures PTO shafts, planetary gearboxes, worm gearboxes, precision gears and hydraulic cylinders, so a complete implement drivetrain can be sourced from one supplier.

Can you supply volume production and long-term agreements?

Yes. We support single-unit purchases as well as large-volume customisation and long-term supply agreements. Contact us with your annual volumes and required specifications to discuss terms.
