I think you mean an Iseki, as an Esky is a cooling box. I don't know this tractor and can't find any information on it, perhaps ask someone else on youtube that actually has one of those tractors or an Iseki dealer.
This has an upgraded engine which is the D850 rated at 18HP. Not sure what the PTO rating would be and over the years I am sure a few horses have run away.
It's 80cm I think, but you can get 90cm and 100cm too. Any tractor store has them. It's a Portuguese brand, I can't remember the name. You can also buy cutter attachments online, you will also need the 3 point hitch arms.
I was reversing as I did not know the terrain and cut in reverse in order to then be able to see where I am driving in case there is an unexpected drop off. I have mowed in reverse for years with no issues. I mowed steep sections where I could only go down in reverse and back up the hill forwards as there was no space to turn.
I don't know. The tractor is very noisy, it stinks and burns oil. Exactly what you left the Netherlands for. Moreover the thing is slow. You could have done the same amount of work in the same time with a french billhook. That thing will cut those brushes like butter, but quiet and without polluting half the country. And besides that, it's really good for your condition and muscle building.
It was really tough work, I have done it previously with just a 2 stroke brush cutter and even then it took 4 times as long. Of course a tractor is slow, but you don't buy a tractor to go fast. You buy a tractor to do heavy work for you and faster than doing by hand. I did not leave the Netherlands for the pollution, or the life. That is a very long story for another day.
