Yea just order the infinite kit listed for the '98 and newer machines. You can convert 800 head back to infinite or if you have 500 there used to be a kit with instructions. Kit is likly broke down into individual parts these days. Don't know if you will see the benifit you are looking for unless you ground is very uneven. You could think about spring rod senser on both sides and wire up accordingly if realing needing both side to sense on that 25' head
