Disc mower

I'm currently using a new Holland 451 7' sickle mower on my 3020 John deere. I'm looking to see what would be a good fit for me in disc mowers for my 3020 to handle. Wanting to stick the sickle on my little Massey Ferguson 35 and run the disc mower on the 3020. Looking in the range of $1500 to $3500 range. Any opinions appreciated on any mowers. Thanks
