The Iseki TS1910 appears to be the same tractor. With the same 2 cylinder engine (Isuzu 2AA1 1.0L) 3.8 quartsMy dad is changing the oil in his Bolens tractor and we don't have access to the user manual to find out how much oil it needs, and that is about the only useful info TractorData doesn't have. Can anyone tell us offhand?
