UHI AUPAX 4090-H Elite 90HP Tractor | Wet Brakes | Rexroth Hydraulics | A/C Cab

UHI AUPAX 4090-H 90HP ELITE 4WD TRACTOR WITH A/C CAB & FRONT END LOADER

The UHI AUPAX 4090-H is a heavy-duty 90HP Elite 4WD cab tractor designed for Australian farms, livestock operations, larger acreage properties and demanding agricultural applications.

Built on the reinforced AUPAX TH platform, the 4090-H combines strong turbo-diesel performance, a 12F + 12R synchronised transmission, wet brakes, versatile rear hydraulics and a heavy-duty front-end loader. It is designed for operators who need one tractor capable of handling loader work, PTO-driven implements and demanding hydraulic attachments.

Powered by a 3.47L 4-cylinder XinChai 4D35ZT turbo-diesel engine, the 4090-H produces 90HP at 2,400 rpm and up to 360Nm of torque, providing strong pulling performance for loader, field and implement work.

The 12 Forward + 12 Reverse synchronised transmission combines four main gears with Low, Medium and High ranges, giving the operator a practical selection of working speeds from approximately 1.95 to 34.13 km/h. A dedicated forward/reverse shuttle makes repetitive direction changes easier during loader operations.

Selectable mechanical 4WD and a mechanical rear differential lock provide additional traction when working in loose soil, paddocks, mud or uneven terrain.

HEAVY-DUTY FRONT END LOADER

The AUPAX 4090-H is equipped with a heavy-duty Front End Loader designed for everyday farm and property material handling.

The loader provides an 800kg rated lifting capacity and up to 1,286kg maximum lifting capacity, with a maximum lift height of 3,110mm.

Combined with a versatile 4-in-1 bucket, the loader can be used for much more than basic loading. It is suitable for moving soil, gravel, mulch, feed and other materials, as well as grabbing, clamping, levelling and general property maintenance.

POWERFUL REAR HYDRAULICS

One of the standout features of the AUPAX 4090-H is its rear hydraulic and implement-control package.

The tractor provides 50 L/min hydraulic flow together with three rear hydraulic remote circuits with float functionality, giving the operator greater flexibility when connecting hydraulic agricultural implements.

A Rexroth multi-way hydraulic valve with adjustable flow allows hydraulic response to be better matched to different attachments.

The rear linkage uses twin external lift cylinders together with a pressure-down control system, providing powered lifting and controlled downward pressure for rear-mounted implements.

The CAT II three-point linkage provides up to 24kN of lift force measured 610mm behind the hitch, while an external rear lift control assists when connecting and positioning implements.

540 / 1000 RPM PTO

The mechanically selected 540 / 1000 rpm rear PTO allows the 4090-H to operate a broad range of agricultural equipment including slashers, rotary hoes, spreaders, seeders, hay equipment and other PTO-driven implements.

WET BRAKES & HEAVY-DUTY TH PLATFORM

The AUPAX 4090-H features wet brakes integrated into the heavy-duty TH-platform driveline.

The oil-immersed braking arrangement is particularly well suited to demanding agricultural environments, providing consistent braking performance while helping protect braking components from dust, mud, moisture and external contamination.

The reinforced TH platform, heavy-duty axle arrangement and 12-inch double-acting clutch are designed to support both front-loader operations and demanding rear implement work.

HIGH CROP CLEARANCE & FIELD CAPABILITY

The 4090-H TH platform provides approximately 505mm of crop clearance, helping the tractor work across a wider range of paddock and crop applications.

Large agricultural tyres, mechanical 4WD, differential lock and a minimum ground clearance of 390mm provide a stable and capable platform for uneven Australian farm conditions.

COMFORTABLE ELITE A/C CAB

The fully enclosed air-conditioned cab is designed for operators spending long days in the tractor.

The operator environment includes a GRAMMER suspension-style seat, accessible side-mounted transmission and hydraulic controls, adjustable steering, roof-mounted HVAC and broad panoramic glazing for excellent visibility around the tractor and loader.

The spacious cab, flat-floor layout and wide glass area help improve comfort and reduce operator fatigue during extended loader and field operations.
