The 8165 a is powered by a six-cylinder diesel engine of 6,596 cm³ displacement, delivering 110.4 kW (150 hp) at 2,200 rpm. At an unladen weight of 5,575 kg, a wheelbase of 2,720 mm and a top speed of 30 km/h, the tractor is a strong representative of the upper mid-class of those years, at a ratio of roughly 50 kg of weight per kW of engine output.
Six-cylinder tractors of this power class handled heavy soil cultivation in the 1980s through the three-point linkage to ISO 730 and drove large implements through the 540 or 1,000 rpm power take-off, from heavy ploughs to large disc harrows, seed drills and forage trailers on bigger fields. The 30 km/h top speed limit was standard for this vehicle class and geared mainly toward field work rather than fast road transport between distant plots.
On a used 8165 a, it is worth checking the crankshaft and oil pan for leaks and the clutch for wear, since six-cylinder machines of this age often ran in continuous duty across many seasons. The front axle should also be closely assessed given the tractor's substantial unladen weight and years of field work.
