Re: jd 4410 3-point backhoe ?
If you add a subframe to help support the 3pt arm mounting area and tie it in with the loader frme. I'm not sure how the top link for your 3pt attaches to the rear axle but that area might need some re-enforcing also.
After looking at a lot of 3pt mounted 'hoe's and seeing some damaged tractors from using them without a sub-frame I determined that it seems that most of the problems came from putting too large of a backhoe on for the tractor.
When selecting a 3pt BH you have to size one that is smaller than what would normally be used with a sub-frame mount.
Kubota is usually very conservative with their equipment and offered a factory 3pt BH for the B32/3300 that wouldn't void the warrenty, if you looked at the specs. it was very detuned from the sub-frame mounted BH. 1.5ft less digging depth and a lot less dipper force.
I think you can use a 3pt BH without damaging the tractor, just brace it and/or size it a little smaller, I like the 3pt because you don't have to r&r the 3pt components. The only reason I'm going with a subframe mount is the 3pt puts the BH too far out the back for me.
