9GD-2.5 Tractor-drawn Sickle Bar Mower
The Jummos 9GD-2.5 Tractor-drawn Sickle Bar Mower is a trailed reciprocating mower that cuts grass, alfalfa, and forage crops at a 2.5 m working width. As a sickle bar mower manufacturer in China, Jummos builds this model with a 34-section reciprocating knife, a 540 rpm power take off drive, and a towed frame that runs behind tractors from 15 kW, which puts high daily output within reach of small and mid-size tractors.
The cutter bar leaves a clean 50 to 70 mm stubble and lays the crop in an even swath ready for tedding, raking, and baling. At a working speed of 6 to 10 km/h, field capacity reaches 2.0 to 3.0 hectares per hour with a single operator, and the bar folds to the vertical transport position for road travel and storage.
Key Benefits
- 2.5 m cutting width – Covers 2.0 to 3.0 hectares per hour at normal working speed, enough capacity for medium farms and contract mowing without stepping up to a heavy self-propelled machine
- Low power requirement – A 15 to 35 kW tractor is sufficient, so the mower works with the compact and utility tractors most farms already own
- Reciprocating cutter with 34 knife sections – Shears the stem cleanly instead of tearing it, which protects regrowth and keeps leaf loss low on alfalfa and fine grasses
- Trailed design – The machine carries its own weight on its wheels rather than loading the tractor’s three point linkage, an advantage on lighter tractors and long working days
- Adjustable 50 to 70 mm cutting height – Set the stubble to suit the crop and field surface, leaving enough residue for quick regrowth
- Low fuel and power draw – A reciprocating bar consumes far less power than a rotary or disc mower of similar width, which shows up directly in fuel cost per hectare
- Vertical transport position – The bar folds upright to reduce transport width for road travel, gateways, and shed storage
- Simple field serviceability – Knife sections and guards are replaceable individually, so a damaged section is a quick roadside repair rather than a workshop job
- One operator – No second person is needed for normal mowing work
- OEM and customization available – Color, configuration, and branding can be adapted for distributors and brand partners

Applications & Use Cases
- Hay and alfalfa mowing – A clean shearing cut preserves leaf and protects the crown, which matters most on repeat-cut alfalfa stands
- Natural grassland and pasture – Handles mixed grass swards and rough pasture where stem thickness varies across the field
- Forage for livestock farms – Cuts and lays the swath for wilting before it goes to the baler, chopper, or TMR mixer
- Silage preparation – Mow, wilt, then bale and seal with a baler wrapper to produce quality wrapped silage
- Smallholder and cooperative use – The 15 kW minimum power requirement suits farms and village cooperatives running compact tractors
- Roadside, embankment, and field margin cutting – A sickle bar copes with uneven ground and light scrub better than a fine-tolerance rotary deck
- Contract mowing – Low power draw and low running cost per hectare keep margins healthy on custom work
Operation & Setup Notes
- Match the mower to a tractor of 15 to 35 kW with a 540 rpm power take off, and confirm the drawbar height so the machine tows level
- Check that the PTO shaft length is correct through the full turning range before the first pass, since an over-extended shaft is the most common cause of driveline damage on trailed implements
- Set cutting height between 50 and 70 mm according to crop and ground surface, leaving enough stubble for regrowth
- Work at 6 to 10 km/h; drop toward the lower end in dense or lodged crops and lift the speed in light, evenly standing grass
- Inspect all 34 knife sections and the guards before starting, and keep spare sections and rivets or bolts in the tractor toolbox
- Grease the pitman drive, bearings, and wheel hubs at the intervals given in the manual, since reciprocating drives depend on consistent lubrication
- Keep the knife sharp; a dull section tears the stem instead of shearing it, which slows regrowth and raises power demand
- Raise the bar to the vertical transport position and secure it before moving on roads or through gateways
- Plan for overall dimensions of 2000 x 4300 x 950 mm and a structure weight of 490 kg when arranging transport and shed access
Frequently Asked Questions
What tractor does the 9GD-2.5 need?
Any tractor in the 15 to 35 kW range with a 540 rpm power take off and a standard drawbar. Because the machine is trailed rather than mounted, it does not load the tractor’s three point linkage, so lighter tractors can handle the full 2.5 m width.
How much can it mow in a day?
Field capacity is 2.0 to 3.0 hectares per hour at 6 to 10 km/h. Actual output depends on field shape, crop density, and headland turns, but a full working day of 8 hours realistically covers 15 to 20 hectares.
Sickle bar or disc mower, which should I choose?
A sickle bar shears the stem between moving and fixed sections, which gives a cleaner cut, lower power demand, and lower fuel use. A disc mower cuts by impact, works faster in wet or lodged crops, and tolerates rougher handling. For hay and alfalfa where forage quality and running cost matter, and where tractor power is limited, the sickle bar is usually the better fit.
What cutting height does it leave?
Average cutting height is 50 to 70 mm. That range leaves enough stubble to support regrowth and keeps the bar clear of soil and stones on uneven ground.
Are knife sections replaceable?
Yes. The bar carries 34 individual sections that can be replaced one at a time, so a strike against a stone or hidden obstacle does not put the machine out of service. Keeping a set of spare sections on hand is standard practice.
How is it transported between fields?
The cutter bar folds to a vertical position, which reduces transport width and lets the machine follow the tractor through gateways and along roads. Overall dimensions in working position are 2000 x 4300 x 950 mm and the structure weight is 490 kg.
Can it handle tall or lodged crops?
Standing crops present no difficulty. In lodged or badly tangled material, reduce ground speed and, where possible, mow in the direction the crop is leaning so the sections feed cleanly instead of pushing the stems ahead of the bar.
Is OEM or customization available?
Yes. Color, configuration, and brand identity can be adapted to your operation or distribution brand, and OEM supply is available. Contact the Jummos sales team to discuss your requirements.
