Eicher Mammut, Wotan

Eicher did not extract very high power from their engines. In the 1969 model, the updated Mammut's 3.9-liter direct injection diesel power increased to 62 horsepower. The following year it rose to 65 hp, and in 1971 Eicher introduced their first turbocharged model. The Mammut HS/TL had 75 hp.

The Mammut transmission was still ZF’s 8+4 or hydrostatic HR. The 1971 HS model was a completely different tractor. Massey Ferguson, which had become Eicher's owner, began to bring its own technology into Eichers, and in the HS and HS/TL models, the powertrain was sourced from the MF 185. The Multipower quick shift was always standard and was marked on Eicher as HS (Hydraulische Schaltgetriebe). The four-wheel drive model continued with the Eicher/ZF powertrain.

In 1968, Eicher introduced its first four-wheel-drive model. Named after a prehistoric god rather than an animal, the Wotan came in 80 and 95 horsepower versions, both available with rear- or four-wheel drive. The engine was 5.89 liters in displacement. The transmission was a partially synchronized ZF T 335, also used by, among others, IH and Schlüter. It had 12+5 gears (the highest gear did not work in reverse) and with crawler gears 16+7.

In 1973, Wotan’s power rose to 100 horsepower. Massey Ferguson sold this model in some countries under the name MF W II.
