I think the 485 is the perfect size for the 4035. I have been thinking about maybe upgrading to a 5035 tractor, but still wont go with a bigger backhoe. I agree with ranwin33 about taking time to do your job, after all it is a "compact tractor", not a full size backhoe. I have a 16"and a 10"bucket. The smaller bucket works better for digging stumps and the main thing is to take small bites and dig under them. Both of my buckets came with teeth at no extra cost. If you pop the relief valve then take less at a time or dig farther around under. There are ways to boost the hydraulic pressure, but be very careful. I have 55 gallons of window wash in each rear tire and have still picked one wheel off the ground using the loader with the backhoe on without touching the pump relief. You can get the 485 with a pto/hyd pump and reservoir from some Mahindra dealers if you want, but in my opinion, it's not needed. As far as the mounting system, I think taking the 3pt arms off is a small price to pay for a super heavy duty backhoe mount rather than a 3pt mounting system. Once you get things figured out, it only takes five minutes to take the arms off and another five to mount the backhoe. Good luck and I hope this helps.
