M8 Overview
The Atrac M8 Cab Chassis is derived from the Goldacres G8 Super Cruiser self-propelled model which forms the basis for a very versatile platform. This machine can be used for a wide range of accessories including spreader bodies or any other application that requires a high capacity, high clearance versatile tractor built to carry a load.
The M8 features a rigid chassis, suspension and mechanical driveline system which provides the machine’s foundation. The main chassis is a fully welded, torsionally rigid semi truss structure.
Combine this with a full mechanical driveline to give uncompromising power, reliability and tractability to the ground.
10 tonne carrying capacity

Cabin
Welcome to business class
The centrally located cabin with suspension and air ride seat help reduce operator fatigue. Features include the very latest in European styling and finishes, narrow profile four post frame with external truss Roll Over Protective Structure (ROPS), double skinned rear wall and extensive sound deadening provide a strong, yet peaceful uninterrupted view of the job at hand.
Seven way adjustable seat, adjustable side console and adjustable steering column ensure operators of all sizes can find a place to do their best work.
A padded training seat with seatbelt is fitted which is large and comfortable without hindering the operator’s vision or space. The seat also folds away to reveal a large storage area with optional cooling module for food and drink.
The cabin is mounted high on the chassis, with the bonnet mounted low. This gives an almost completely uninterrupted view from the front window.
Driveline
Engine / Transmission
Cummins Tier 3 QSB 6.7L – 6 cylinder engine rated to 194kw (260hp) and 987N.m (728 lb-ft).
Allison 3000 series 6 speed automatic transmission. Electronic push button selector. Double overdrive reduced engine RPM whilst still maintaining 50 km/hr transport speed. Lock up torque converter improves performance whilst drastically reducing heat build up and fuel usage.
Drivetrain
Large vertically stacked cooling system for fuel, transmission, water jacket, charge air and air conditioning. Optimised cooling fan to reduce noise whilst still providing maximum air flow.
Over the radiator (OTR) air cleaner system with twin stage filtration provides cool clean air to the engine.
Cummins Tier 3 QSB 6.7L – 6 cylinder engine rated to 194kw (260hp) and 987N.m (728 lb-ft).
Allison 3000 series 6 speed automatic transmission with electronic push button selector. Double overdrive reduces engine RPM whilst still maintaining 50km/hr transport speed. Lock up torque converter improves performance whilst drastically reducing heat build up and fuel usage.
450L polyethylene fuel tank with both left and right hand side filling points provides enough fuel for the longest spray days.
Full-time 4WD system with lockable centre differential provides a 50/50 power split between front and rear axles. An internal ratio step down of 30% reduces drive shaft speed, resulting in longer universal joint life, reduced noise, vibration and harshness (NVH).
Front axle features extreme rated planet hub reduction design with internal wet multi disc brakes. Fully incorporated suspension mountings and mechanical link between front wheels ensures correct Ackerman angles and alignment.
Rear axle features extreme rated planet hub reduction design with internal wet multi disc brakes, negative park brake and differential lock. Fully incorporated suspension mountings including the anti-sway bar and tow bar point round out the package.
