Andrew asks…


Having completed a full strip down and rebuild of the engine according to the dvd I have now bought the Hydraulics dvd and am about to start looking at that end of the tractor.

I noticed that Ian mentions using multigrade oil in the gearbox/hydraulics. Having Googled this and looking at a few forums I am now confused. Should I be using 32 grade hydraulic oil or multigrade engine oil?

Also what about my log splitter which I use on my Ford 4000 with 32 grade hydraulic oil in it. If I use it on the Fergy with different oil then the oil will surely get mixed?



Hi Andrew,

In the Fe35, the recommended oil is SAE50 in our climate (or SAE 40 in colder climates). However, these days you would just use 15w/30 farm universal oil (or possibly even a dedicated premium transmission oil such as 10w/40). Definately not 32 grade hydraulic oil – that would be used in specific hydraulic systems (ie. without a tractor gearbox running off the same reservoir). Also definately not dedicated engine oil or any dedicated gear oils.

As for the mixing of the oil when you swap the log splitter between the two tractors?? Well that’s one reason why the oil should be changed at regular intervals – so that the correct oil in the tractor doesn’t get too diluted/contaminated with incorrect oil from other systems.

Hope that helps.

Kind Regards,
