Topping tomato plants?

[chiefbeaz]

I use the Florida weave system to hold up my plants. I use about 7 foot tall fence post aka T post. Once the plants reach the last string support they start droping towards the ground like a weeping willow tree. I would guess the plants reach on the average 10 foot tall, maybe more. This is not a big problem, but it is messy looking. I have no problem picking the tomatoes, I just get my arm under the hanging branches and raise them up and pick any tomatoes I find under the branches.

My question is, what would happen if I topped the plants once they reach a certain height? Do the plants quit producing or do they keep bearing fruit? I don,t have a clue . Any one have any idea about topping the plants ?
