Small sickle mowers?

Do small sickle mowers that DONT cost thousands of dollars exist? I have a small tractor with an 18 horse diesel, cat 1 three point and two speed pto (540 and 1000) that id love to be able to mow with in tight spots. Problem is the only small mowers i can find are eithermid mounts meant for garden tractors or are new and $3500. Anyone know where i can find one or what i should be looking for???
