Rear Mounted Disc Mower for Tractor | PTO Driven Forage Grass Cutter

Our tractor rear mounted disc mower is a professional heavy-duty agricultural grass cutting equipment specially designed for large-scale farm pasture, alfalfa, ryegrass and all kinds of forage harvesting. This PTO-driven rotary disc grass cutter connects to the tractor's rear three-point suspension frame, powered by the tractor power take-off shaft to drive multiple high-speed cutter discs for continuous, clean grass cutting.

Compared with traditional belt-drive lawn mowers, our gear transmission disc mower features stable operation, low breakdown rate and minimal maintenance cost, becoming the top choice for global farmers, ranchers, agricultural distributors and farm machinery importers looking for durable high-yield hay harvesting machines.

The high-efficiency tractor disc mower relies on 5 core matching parts to realize automatic pasture cutting, every component optimized for long-time farm heavy load work:

Support Tractor Power Source Matched with 35-90HP farm tractors, power output shaft transmits power to the whole mowing unit, supporting continuous all-day field operation without power lag.

High-speed Metal Cutting Discs 4-8 thickened metal cutter discs are the core cutting unit of the farm disc mower; each disc installs two sharp alloy blades, rotating at 2900rpm to slice thick grass, weeds and alfalfa neatly without winding grass.

Wear-resistant Cutting Blades High-hardness metal blades with strong cutting performance, fit tall forage and uneven pasture land, deliver uniform mowing effect and extend service life.

Heavy-duty Base Frame Thick steel base protects cutter discs and internal gearbox, adjustable cutting height & angle to adapt hills, flat pasture and complex farm terrain.

Full Gear Drive System Cancel unstable traditional belt drive, use full gear transmission to transfer power to each cutting disc, greatly reduce failure probability and cut later maintenance expense.

Simple operation design lowers farmers' learning cost, standard mowing steps as below:

Pre-operation inspection: Check tractor PTO connection, blade tightness and gearbox lubrication to ensure the disc mower works normally.

Adjust cutting height & angle via the side lever, match with local pasture growth height.

Start tractor power take-off, stand behind the mower and keep safe distance from rotating cutter discs.

Drive tractor forward evenly across the pasture, keep the mower base close to ground to get perfect clean cutting effect.

Maintain steady travel speed 4-12km/h for uniform hay cutting across the whole field.

After finishing mowing work, turn off tractor engine, wait all cutter discs fully stop rotating before leaving the farm machine.

1. Ultra-high Working Efficiency

Equipped with 4-8 high-speed rotary cutter discs, each disc carries two sharp blades. The mowing capacity reaches 1-2 hectares per hour, greatly shorten pasture harvesting time and save farm labor cost, ideal for large ranch & commercial hay farms.

2. Stable Gear Transmission Structure

All cutting discs driven by integrated gearbox instead of easy-wear belts. No belt slipping, no frequent replacement parts, stable running even on bumpy farmland, extremely low failure rate and save long-term repair cost for farmers.

3. Wide Adaptability for All Forage

Fit alfalfa, ryegrass, wild pasture, tall grass and all kinds of livestock forage; adjustable cutting width from 1.67m to 3.2m, match small, medium and large tractors from 35HP to 90HP, meet different farm scale demands.

4. Clean & Neat Cutting Result

2900rpm high rotating speed of cutter discs cuts grass smoothly without crushing or pulling forage, keep hay intact for subsequent drying and baling, improve overall forage quality.

5. Solid & Reliable Construction

Whole machine adopts thickened carbon steel frame, anti-collision base and sealed gearbox, resist mud, stone impact and long-time outdoor farm use, long service life for global agricultural users.
