DAYEE DY400-815SB-00 Diesel Crawler Mower
The DAYEE DY400-815SB-00 is a remote-controlled diesel crawler mower with a front swing-blade cutter 1000 mm wide. DAYEE lists a Chang Chai 195 engine described as horizontal, two-cylinder, four-stroke with electric start, swing-blade adjustment of 0–240 mm, 0–6 km/h travel, a maximum tilt of ≤45° and 150 m remote distance. The machine measures 1820 × 1140 × 760 mm and weighs 525 kg net, 555 kg gross. Start with the cutting job and the ground setting, then plan access and transport.

Build my procurement briefWhat the swing-blade cutter is for
The factory photo shows the front cutting assembly with its swinging blades exposed, working in a field. The table gives a 1000 mm cut and 0–240 mm swing-blade adjustment. Blade material, blade count, rotor speed, maximum stem diameter and residue capacity are not listed.
Tell DAYEE what you will cut, how dense it is, the ground condition and the result you need, and ask for the cutting-assembly specification. This is a mower; ask separately about stones or metal debris. The series introduction about 13–21 inch mowers is generic text and does not describe this machine. Machines from other makers for rough vegetation sit in our garden and forestry category.
The 0 mm ground clearance and blade setting
The table prints minimum ground clearance 0 mm, separately from swing-blade adjustment of 0–240 mm. It does not say where either is measured from, whether it describes a working or transport setting, or what touches the ground.
Ask DAYEE for the setting diagram and operating instructions. Get the lowest point of the machine, the blade-adjustment reference point and the allowed ground-contact conditions for your build in writing before cutting near soil, stones or obstacles.
Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Exact model | DY400-815SB-00 [1] [2] | Same table on the official page and in the brochure. The 815 in the code is not an engine size; the table has no displacement row. |
| Engine label | Chang Chai 195 [1] [2] | As printed. Ask for the engine maker's full designation, revision, displacement and rated output. |
| Engine type | Horizontal, two-cylinder, four-stroke, electric start; diesel [1] [2] | DAYEE's description. Check it against the nameplate and manual of the engine that ships. |
| Cutting width | 1000 mm [1] [2] | Width of cut. The machine itself is 1140 mm wide. |
| Swing-blade adjustment | 0–240 mm [1] [2] | Printed as the adjustable range of the swing blade, with no reference point. Ask how it relates to cutting height. |
| Driving speed | 0–6 km/h [1] [2] | Travel range. Working speed under cutting load and area per hour are not given. |
| Maximum tilt | ≤45° [1] [2] | No direction, grip, vegetation, braking or turning conditions are given. |
| Minimum ground clearance | 0 mm, as printed [1] [2] | The table does not say where this is measured or at what setting. Ask DAYEE to explain it. |
| Control and travel | Remote control; crawler; 150 m remote distance [1] [2] | Radio band, link-loss response and stopping come from the manual. No autonomous mode is listed. |
| Mass | N.W. 525 kg; G.W. 555 kg [1] [2] | Net and gross catalogue weights. Confirm for your configuration, with handling points. |
| Machine dimensions | 1820 × 1140 × 760 mm [1] [2] | Overall machine size. Turning space and service clearance are extra. |
| Package dimensions | 1880 × 1200 × 810 mm [1] [2] | Shipping package size, for freight planning. |
Machine size and weight for route checks
This model gives an overall size of 1820 × 1140 × 760 mm and 525 kg net, which is enough for a first route check. A clearance drawing will still be needed.
| Size or weight | What else your route needs |
|---|---|
| Gates and rows | Compare your route with the 1140 mm machine width, then get the configuration drawing and the side clearance needed. The 1000 mm cut is narrower than the body. |
| Turning near trees or equipment | Give DAYEE your turning area and ask for the turning sweep and any restrictions. No turning radius is published. |
| Ground loading | Actual mass and track contact figures for your build, to check soft ground. |
| Service space | Room needed to inspect the machine, service the cutter and reach the engine. |
Diesel engine and drive documents
The Chang Chai 195 label comes with a horizontal, two-cylinder, four-stroke, electric-start description. Nameplate, manual, power curve, tank size and driveline diagram are not provided.
Identify the engine
Ask for the nameplate designation, revision and manual that ship with your order, and check them against the catalogue description.
Get the drive layout
How the engine drives the cutter and the tracks, operating settings and service parts.
Get the ratings
Rated output and its conditions if you are comparing machines. Displacement, fuel use and cutting power are not given.
Set service duties
Engine and machine warranty and support split, maintenance schedule and spare-parts documents for this model.
Slope, remote range and stopping
The ≤45° tilt row gives no direction, grip, load or manoeuvre. The 150 m remote row gives no radio conditions or supervision rule. DAYEE publishes no autonomous navigation or obstacle avoidance.
Ask for the model's operating limits and the controller behaviour: what stops the engine, cutter and tracks, what happens if the signal drops, and how to stop and recover the machine. Ask for any stability or stopping test data, and keep demonstrations inside DAYEE's approved conditions. DAYEE's DY210-224SB-00 and DY330-764SB-00 crawlers and the DY210-3000SB-00 remote mower each carry their own tilt row, so compare them only under matching written conditions.
Transport at 525 kg net and 555 kg gross
Gross weight and package size are for transport planning. The packing that makes up the difference from net weight is not listed.
| Transport task | What to get for the shipped machine |
|---|---|
| Vehicle and package | Actual packed size and weight, packing list and your receiving limits. Book freight on those, using 1880 × 1200 × 810 mm as a first guide. |
| Loading | Approved lifting and loading points, ramp requirements and how the machine should be set for loading. |
| Securing and storage | Tie-down points and the transport and storage procedure, including the cutter, engine and electrics. |
| Recovery | How to recover a disabled crawler, with tow points marked. |
Acceptance and handover
The catalogue gives no area-output figure, price or warranty period. The order should settle the cutting job, the blade and clearance settings and the machine itself.
Fix the build
DY400-815SB-00 revision, engine, cutting blades, guards and drive and controller documents.
Attach the geometry
Blade-adjustment reference point, ground-clearance explanation, operating limits and machine and transport drawing.
Agree the trial
Vegetation or residue, ground, settings, result and how stops are counted. Judge it on work done, with 0–6 km/h as top travel speed.
Handover pack
Operating, maintenance and transport instructions, spare part numbers, market documents and written engine and machine support.
Buyer questions
Does 815 mean an 815 cc engine?
No displacement is listed; 815 is part of the model code. Ask DAYEE for the engine displacement and rating. [1] [2]
Is 0–240 mm the cutting height?
DAYEE calls it swing-blade adjustment and gives no reference point. Ask for the setting diagram to see how it relates to cutting height. [1] [2]
