New 4320 owner

The attachments are the same as the machine, you get what you pay for.
I will follow the factory suggestion that it shoud be adjusted so that it takes three seconds for the TPH to decend. That should take the boom out of it.
I had the back lights installed on mine but left the front lights off because I feel that the factory mounting location is too low. I know we shouldn't drill or weld the ROPS so looking at the set up I figured that I would TAP the approx 3/4 inch hole on the back side of the ROPS and buy two more lights that are the same as the rear lights and mount them that way with two brackets. I will try and splice into the rear light circuit and see if the fuse can carry two more lights.
Any experts know what the load will be and if the fuse will carry the load?

Gary, OEM fuse size is normally 130% of circuit load. This number is rounded out to the next highest fuse size avalible.
It's the wire size, distance and fuse socket amperage capability that you should worry about. The circuit draw will be the highest when you first turn lamps on due to the low resistance of the cold lamp filiments. Be sure to test load current draw with tractor running due to higher then static battery voltage of the alternator. With tractor nothing runs on battery voltage. Instead, every thing runs on alternator voltage if the alternator is properly sized.
On another matter. Does the 448 back hoe boom a float mode for bucket dragging with the dipper when digging ditches?
Please check out my posts on the 48 hoe for details on what is hoe float.
Good luck with your new tractor.

thanks,
george

I really don't know exactly what you describe as floating the bucket. I wll look at the instructions and see if they show anything.
Could you describe the function in a little more detail?
All I have done is dig stumps and rocks so far but ditches are in the plans.

Gary, check out the post and tread below to get a fix on backhoe boom float. It is a comon feature on Bradco hoes.

I don't how to make acess to the above page direct but a search for the above post number should take you there.
What is odd is that Amerquip, who make the 48 hoe for JD, puts boom float on their hoe but appartantly not the 48 hoe they sell to JD.
I am thinking of buying a 4320 with the new hoe and would like to find out about the boom float option first.

cheers,
george

Keoke,

( What is odd is that Amerquip, who make the 48 hoe for JD, puts boom float on their hoe but appartantly not the 48 hoe they sell to JD. )

I believe that they also put float on the ones that they made for Bush Hog.

Jim, have you got any idea as to why JD does not want boom float on thier hoe? Do you suppose it has anything to do with the way hoe is mounted up, or possibly simply to save on cost?

George,

I can't think that it would affect the mounting.

Looking at the technical manual for the 48 hoe, I see that all six valve sections are equipped with load check valves. Can you use a load check valve on a float circuit?
