Unknown model number

Hi anyone who could help me, we recently have been given a zetor tractor but the model plates and stickers are all missing, and we would like to find out what it is, the only info I have it is 2wd, it's a 3 cylinder engine number is 3001004 and another number on it was 77974 please any info would be great we are also in australia if this makes any difference thank

Its a 3011 or a 3511 because the engine serial number starts with the engine type number: the 3011 and 3511 had the 3001 motor.

Being in Australia i suppose its a 3511. dont know when they started importing them down under but i guess its a 3511.

If it has a square nose its a 3511. round nose is 3011.

Thanks for that info, just wondering if this number means anything 77974 we found this number on the gearbox just back from the bell housing on the right hand side. We think it is the 3511 as it has more of a square shape. Thanks
