Hell sell the Kubota and buy a CAT D9. Go big or go home.
It is amazing how every time someone asks for help the solution is "you need a bigger tractor." Maybe that is the biggest tractor he can afford. Sure you can do it faster with a larger tractor but that does not mean the work can not be done with what he has to work with.
There is not a lot of information given as to what kind of work needs to be done but I bet a lot could be done with the
L3301. Large stumps or mountains of dirt may require some bigger equipment at some point but a lot of hard work and time the
L3301 will clean up a lot of a mess. After all isn't the reason for a tractor is to work it?
If I only had a bigger tractor I could
pave farm the world.
