Xinglaihe TC504-A8 / TC504B-A8 Compact Tractor
The Xinglaihe TC504-A8 is a compact wheeled tractor with an XY484 engine rated 36.8 kW at 2800 rpm, switchable two- and four-wheel drive and a category 1N rear linkage. Its product page links a design table headed TC504B-A8. The table lists PTO speeds of 644 and 812 rpm, a 1337 mm overall width and eight-speed high and low ranges. Before choosing implements, confirm the exact model, the PTO interface, lift capacity and the complete tractor mass with Xinglaihe.

Build my procurement briefWhich model name applies
Xinglaihe's page and its linked files use more than one model name. Ask which one goes on your quotation and nameplate.
| Where it appears | What it means for your order |
|---|---|
| Product heading and bonnet photo: TC504-A8 | The catalogue name. Confirm the build and options for your order. |
| Parameter image header: TC504B-A8 | All figures on this page come from that design table. |
| Parameter image filename: TA504B-A8 | A file name only; no TA504 product is listed. |
| Nongjitong industry page: TC504B-A8 | Names Zhejiang Xinglaihe and repeats much the same figures. |
PTO speeds: 644 and 812 rpm
The table lists rear PTO speeds of 644 and 812 rpm. These differ from the common 540 and 1000 rpm, so check your implement's required speed against them. Ask Xinglaihe for the PTO speed chart with matching engine speeds, the shaft and spline dimensions, rotation direction and approved operating setup. If the TA304-A9 is also on your list, request its PTO speeds too so both can be checked against the same implement.
The 36.8 kW figure is the engine rating; power at the PTO is lower after transmission losses. Compare a rotary implement's speed and power needs with Xinglaihe's tractor documents, and see the combination run in a demonstration before you buy.

Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Model names | Page/photo TC504-A8; design table TC504B-A8 [1] [2] [3] [4] | The image filename also says TA504B-A8. Ask which model name goes on your nameplate. |
| Engine design rating | XY484; 36.8 kW at 2800 rpm [2] | Engine rating. Drawbar and PTO power will be lower and are not listed. |
| Drive / chassis | Two/four-wheel switch; reinforced cast-iron chassis [2] | Traction and axle-load figures are not published. |
| Overall dimensions | 2920 ×1337 ×2010 mm [2] | Design values. Ask for the size of your build as delivered and transported. |
| Clearance / wheelbase | 330 mm / 1610 mm [2] | Design geometry. Clearance with a mounted tool depends on the tool. |
| Front / rear track | 1020 mm / 1060 mm [2] | Fixed values; no adjustment range is listed. |
| Turning radius | 2500 mm [2] | Test method, brake use and implement condition are not stated. |
| Tyres | Front 7-16; rear 11.2-24 [2] | Front tube and rear tubeless dry-land tyres. Ask about paddy or soft-ground tyre options if you need them. |
| Rear output | PTO 644 /812 rpm [2] | Engine speed at these PTO speeds, shaft size and PTO power are not listed. |
| Rear lift / linkage | Hydraulic lift; category 1N; GB/T1593-2015 cited [2] | Lift force, oil flow, pressure and remote valves are not listed. |
| Emission description | Fourth-stage label in design table [2] | Chinese emission stage as stated by Xinglaihe. Ask for the current certificate and any approval your country needs. |
| Mass shown within engine block | 187 kg [2] | Printed in the engine rows of the table. Ask for the complete tractor mass separately. |
Linkage, lift and hydraulics
The design table lists hydraulic lift and a category 1N three-point linkage to GB/T1593-2015. Lift force and auxiliary hydraulic data are not given, so work through these points with Xinglaihe.
Mechanical attachment
Get linkage dimensions, pin sizes, travel and clearance for the exact tractor and your implement.
Lift and stability
Give implement mass and centre of gravity. Ask for permitted lift and load data and a ballast and axle check.
Hydraulic tools
If the tool runs off the tractor circuit, ask for oil flow and pressure, remote outlets, couplers and return arrangement.
Combined demonstration
Watch mounting, lifting, clearance and the working functions together, following Xinglaihe's instructions.

Width, track and turning on your site
The tractor is 1337 mm wide overall, with a front track of 1020 mm and a rear track of 1060 mm. No adjustable track range is listed. Measure your rows, gates and tool width, and ask for a drawing of your configuration. Compare it with the TA254-A6 / TA254-A9 compact tractor in the same range, and ask for both drawings if row width is tight. With front and rear wheels on different lines, check how they run between your crop rows.
Ground clearance is 330 mm and turning radius 2500 mm, both design values. Ask how they were measured, and try the tractor with your implement on a similar site to check clearance, slopes and headland turns. If you need rollover protection, ask for the approved structure and its documents.
Gear speeds
High and low ranges each have four forward and four reverse speeds. Xinglaihe gives these as design values.
| Range | Speeds in km/h |
|---|---|
| High forward: gears 1–4 | 6.42 /8.10 /15.76 /20.42 |
| High reverse: gears 1–4 | 6.42 /8.10 /15.65 /20.32 |
| Low forward: gears 1–4 | 1.76 /2.38 /4.45 /5.90 |
| Low reverse: gears 1–4 | 1.76 /2.38 /4.45 /5.90 |

Buyer questions
Are TC504-A8 and TC504B-A8 the same tractor?
The page and photo say TC504-A8; the design table and industry listing say TC504B-A8. Ask Xinglaihe to confirm in writing which model you will receive. [1] [2] [3] [4]
Does the tractor weigh 187 kg?
The 187 kg figure is printed in the engine block of the table. Ask for the complete and loaded tractor mass. [2]
Will a 540 rpm implement work?
The table lists 644 and 812 rpm. Get the PTO speed and interface chart and check it against your implement before buying. [2]
Is category 1N enough to lift my implement?
Category 1N sets the hitch dimensions. Match your implement's mass and centre of gravity against Xinglaihe's rated lift and axle and ballast limits. [2]
Tractor mass, price and documents
The table's engine block lists the maker, XY484, rated power and speed, emission stage and then 187 kg. That figure sits with the engine rows; the complete tractor mass is not given. For shipping, trailers, ballast and implement stability, ask for the tractor mass, the configuration it applies to and axle-load information.
The Nongjitong listing shows no price or subsidy figure. Ask Xinglaihe for a quotation and the documents your country requires. Quoting the TB404-A9 / TB404-H1 at the same time gives a like-for-like price check within the Xinglaihe tractor range. Xinglaihe marks all table figures as design values, the emission stage included.
