TOW BEHIND MOWERS

I have about 2 acres of pasture that is often too damp to cut with our 26 HP Cub Cadet tractor.

I have been fortunate to have my neighbor cut it occasionally with his 4 wheel drive (large) farm tractor with bush hog.

Options:

1. Offer to pay my neighbor $ (he is very old and I believe he cuts it to be friendly, but only when he can do it)
2. Hire someone else
3. Purchase a tow-behind mower and tow it with my Grizzly
4. Purchase a farm tractor (probably overkill for my needs)
5. ???

Anyone been down this road ?
