DB 3800 & 4600 tractors

Post by Ozz-DB » Fri Mar 25, 2016 11:12 am

This subject has probably been discussed before-

The DB 3800 & DB 4600 tractors were built specially for the North American market in the late 1960s.
The only information I can find them is that they used 3 cylinder gasoline (petrol) engines.
Were there diesel versions?

What British DB models do they relate to?

Does anyone on this forum own, or has owned a 3800 or a 4600?

The 3800 was a petrol version of the 780 Selectamatic. The 3800 was produced from 1968 to 1971 and it had a 3-cylinder engine with 100 mm cylinder diameter and 102 mm stroke and a compression ratio of 6,75:1. The 4600 was a petrol version of the 880 Selectamatic. The 4600 was produced from 1968 to 1971 and it had a 3-cylinder engine with 100 mm cylinder diameter and 114 mm stroke and a compression ratio of 7,5:1. Both engines was used as diesel versions for other markets than the US.

There is / was one at the DBTC museum in Huddersfield, presumably an imported export model.
