It looks great now - the workmanship and the amount of work you have done is impressive!
Your Agria 8900D has a very low profile style which is understandable due to type of work it was designed for.
Wouldn't rigid frame tractor likely mean lot smaller front wheels and less traction?
Looks like Antonio Carraro has similar style tractors, but the operator seating is little higher.
The rollover protection kind of defeats the idea of low profile tractor...

Thank you Arto!
These type of tractors are called isodiametric tractors because of the equal sized wheels.
Yes a conventional tractor would have less traction at the front, however the bigger rear wheels may make up for it. A conventional tractor has around 40% of the weight at the front axle and 60% at the back.
These isodiametric tractors it's 60% in the front and 40% in the back, so the front wheels do some work along with the rear as the implement puts weight on the rear axle. These are typically a bit lighter than a conventional tractor though, even after wheel weights, but they all have front and rear axle locks, which makes them great pullers as well.
Antonio Carraro was pretty much the inventor of this style of tractor. Up to this day, they're still the best isodiametric tractor out there, it does come with an hefty price though.
After them, Goldoni, Pasquali, Ferrari, Agria, and others started to build their own isodiametric tractors. All based on areas with hills and mountains.
Nowadays, most of these brands offer a reversible operators platoform which is a great feature to have, since you're now facing the attachment lets say mowing brush for instance.
You're correct on the roll over protection. The rear mounted one, pretty much defeats the purporse of these tractors. That's why most have mid mounted ROPS because it folds forward and makes a low profile tractor again.
