Welcome to the Forum bill.
there are several ways to improve the power of those.All three have Woods belly mowers attached, one 5 foot and 2 six foot. The farmall A's are a little underpowered for tall grass but they work great if I don't get too far behind.
I planted several acres of pine and hardwoods a few years ago and they are
just the thing for keeping it clean between the rows.
