Series 51 belongs to Eicher's production in Bavaria, with plants at Forstern and Dingolfing, and lists here the 3151 Tiger II and the Mammut 3551 HS/TL. Both names continue Eicher's tradition of predator naming: Tiger II as the revised second generation of the Tiger name, Mammut denoting the more powerful types in the marque.

The register lists 2 variants with 25.6 kW, or 35 hp, of power from three- and four-cylinder engines of 2,944 to 3,927 cc displacement at a rated speed of 2,000 rpm and 134 Nm of torque. Unladen weights fall between 2,150 and 2,800 kg, dimensions range from 3,180 to 3,670 mm in length, 1,650 to 1,960 mm in width and 1,550 to 1,720 mm in height.
By pairing the Tiger II with the Mammut, series 51 shows the transition between the mid and upper power classes within Eicher's 1960s line-up, competing directly with comparable models from Fendt and Deutz in the West German market.
When buying used, pay attention to the specific powertrain, as the three- and four-cylinder variants need different parts. Clutch, gearbox and hydraulic pump should be checked for wear and tightness, and the bodywork for rust around the wings and bonnet. Front axle bushings and steering linkage are worth inspecting for play built up over decades of field work. An active network of collectors and parts dealers exists for these Eicher classics.
