Hi and welcome from the Scottish Borders.
We have 9 acres ourselves, plus rent another 6 or 7 or so next door. We bought a new Foton tractor, 28hp, 2WD (we didn't want a front loader and the extra cost would have meant that we couldn't have bought any implements). We use it for rotovating (after pigs), topping and harrowing, as well as moving sheep between the fields when ground is too wet to use the car (not a 4WD).
We found it reliable so far, only slight probelm now was that two tyres were a bit flat, but got that sorted. Has so far done all we asked it to do, and our problem was that when we looked 2ndhand was also expensive and as tractor novices we wouldn't have been confident to buy... also found that in this part of the world not many small tractors are sold. This one also fits our standard garage door, so we can lock it into the garage (no cab, so needs cover). We are hoping this one will do us for as long as we need it, so were prepared to invest a bit.
We didn't go for Siromer, because if all built up its not as cheap as it looks. Kubota is VERY expensive, plus so are the implements. I wouldn't go for an older tractor, as my OH is not very good with tractors (and cars, lawnmowers etc etc), so repairs could be quite a hassle.
So we are fairly pleased with it, might try and save up for some hay cutting and turning equipment, once the friendly farmer who bales my hay finds that his baler is beyond repair we might need it...
