Yep, go with the toolholder... I don't know about the larger tractors, but the Ls were 24" wide. The Kohler powered models are probably a couple inches wider due to the larger tires. You can drive between rows, or with short crops, straddle them. And with GRWs on an L you have 9" of ground clearance (and have 14" or so rows instead of 26" rows).
With a 566 you could go narrower than 36" rows depending on the plants. I don't think you could straddle too many crops - at least not for too long - due to the lack of ground clearance.
