The T 800 was the first BM tractor with a dry air cleaner with paper filter, built-in cyclone pre-cleaner and pressure drop indicator, an alternator rated at no less than 475 W, cold starting operated electrically from the cab, and so on. It was also the first that could be supplied with proper front weights, ten at 47 kg (10 individual 47 kg weights). For markets that required a cab, there was a spacious, well-equipped steel cab. The industrial variant, the T 800 I, had nodular iron in the flywheel housing, rear axle casing and rear axle housing, industry-treaded tires and instead of the tubular axle on the agricultural machines, a steering axle from the two-wheel-drive loaders. Terra Trol Mark II, with major improvements, was introduced into production in February 1975. At the same time the cab was upgraded in various ways, including more headroom and greater glass area..
The new D 60 engine was introduced in the mid-1970s.
