How well does the L4060 handle the 273? Is it on the ragged edge or a good match, or somewhere in between? How flat your field is probably figures into the equation quite a bit too.
It did good, very little ram push, unlike the B2410 where you could see the tractor being pushed back and forth, only on a hard hit of heavy grass do I feel it in the cab. The baler only needs 18 PTO HP to run, so power isn't an issue, weight is, and why I went with the one I did instead of a John Deere, the Deere was several hundred pounds lighter at a cost of several thousand $$ more. I figured if my B2410 lasts 20 years without any issues, an L4060 should do the same.
Having 2 tractors is awesome too, really helped with getting the bales put away, I moved the trailer with the lil mule and used the HSTC and forks to gather the bales, 6 at a time to be stacked on the trailer. Eventually once the fields are growing grass instead of weeds, and the yields are higher, I can have the lil mule towing the trailer behind the baler picking up the bales as they come off. My fields are not big enough to triple up tractor, baler, trailer, not enough room to turn it around. Only baling 3 1/2 acres, but my neighbor may want me to do his 4 acres, so 7 1/2 acres of hay should fill a barn.
Now to find a right angle phillips screwdriver so I can attach the Seat pto switch.
