Description
90 HP Elite Cab Tractor
A practical 4WD cab tractor with XinChai turbo diesel power, synchronised shuttle shifting, 50 L/min hydraulics and a matched TZ08D front-end loader package for property and field work.
TH Platform Overview
The AUPAX 4090-H features a compact TH-platform layout with high crop clearance, three selected rear remotes and a practical 12F + 12R drivetrain. The comparison page in the source material positions it as a wider-use field tractor with added rear-hydraulic flexibility.
Power & Field Performance
90 HP XinChai turbo diesel performance
The 3.47 L four-cylinder XinChai 4D35ZT turbo diesel is rated at 90 HP at 2,400 rpm and produces up to 360 N·m of torque. A synchronised shuttle transmission, selectable 4WD and differential lock help the tractor adapt to loader work and field operation.
- 12 forward and 12 reverse gears
- Double-acting clutch and wet brakes
- 540 / 1000 rpm rear PTO
- 120 L fuel tank
- Maximum forward speed 34.13 km/h
Hydraulics & Implement Versatility
50 L/min flow with rear-hitch control
The 4090-H specification lists a 50 L/min hydraulic pump flow, powered lift with pressure-down control, and three hydraulic valve functions with float. Rear lift control beside the hitch helps positioning while working with rear implements.
The source material shows two rear 3PL figures: a detailed technical sheet states 24 kN @ 610 mm, while a summary panel states 28 kN @ 610 mm. Both are kept distinct here and should be confirmed before external publication.
Engine, Cooling & Fuel Capacity
Practical service access, a Donaldson dry-type air filter and a large 120 L fuel tank support everyday operation and longer work cycles.
XinChai 4D35ZT Diesel
Turbo diesel engine producing 90 hp at 2,400 rpm and 360 N·m maximum torque for field and loader work.
Enhanced Cooling
A larger cooling area and separate chassis-oil cooler help manage heat during demanding operation.
Donaldson Air Filter
Dry-type intake filtration helps protect the engine and reduce maintenance frequency.
Large 120 L Fuel Tank
Supports longer operating periods between refuelling stops, with protective mounting around the tank area.
12F + 12R Synchronised Transmission
Synchronized shuttle shifting
Four main gears across three ranges combine with a forward / neutral / reverse shuttle. Side-mounted levers keep the controls accessible and provide a useful spread of working and transport speeds.
Clutch, PTO & Front Axle Design
Double-Acting Clutch
The 4090-H uses a 12-inch double-acting clutch for tractor and implement work. Source material also describes a torque reserve factor above 2.0.
Two-Speed Rear PTO
Mechanically selected 540 / 1000 rpm rear PTO speeds support a range of implement applications.
Front Axle & Chassis
The axle package combines a central spiral-bevel gearset with reinforced wheel-end reduction and wet braking components.
Positive-Pressure Lift
Twin external lift cylinders and shared-oil layout are highlighted in the TH-platform reference material.
Cab Comfort, Visibility & Durability
The enclosed cab combines air-conditioning, practical operator controls, broad glazing and service-friendly access for routine use.
Grammer Fabric Seat
Armrest-equipped fabric seating provides a comfortable operator position for long days.
Roof HVAC Vents
Integrated roof vents and air-conditioning support hot-weather comfort inside the enclosed cab.
Overhead Radio & Controls
The source references Bluetooth radio and USB connectivity; final installed equipment should be confirmed on the offered unit.
Accessible Side Controls
Shuttle, gear and hydraulic controls sit within easy reach of the operator.
Heating, Cooling & Skylight
Integrated climate-control hardware and roof skylight contribute to comfort and visibility.
Panoramic Cab Glazing
Sealed cab glass, front wiper and broad window area support visibility and help keep dust out.
Suspension Seating
Suspension-style seating, headroom and a spacious cab layout support reduced operator fatigue.
Bonnet, Airflow & Service
Streamlined bodywork and practical bonnet access assist routine servicing and daily inspection.
Front-End Loader Engineering
Matched TZ08D loader package
The supplied source material shows the 4090-H fitted with a TZ08D front-end loader and four-in-one bucket. The loader package is designed for handling, clamping, grading and day-to-day property tasks.
Technical Overview
Engine & Drivetrain
Chassis & Hydraulics
Specifications and descriptions are based on the supplied AUPAX 4090-H Features PDF. Comparison information against LOVOL 904 and several TH-platform illustrations are reference materials included in the source. The rear three-point lift rating appears as both 24 kN and 28 kN at 610 mm across the source set; please confirm the final published figure before external use.
