can I cut back my hardy kiwi to the main stock. the plants are close to twenty years old and we need to replace the arbor that they where on. that process would make it easier and I really do not need the fruit this year.

Since these plants are not grafted to a rootstock you technically can cut them all the way back and train a new trunk. However, be aware that this is a very early year. Cutting the kiwivine all the way back to the trunk will lead to excessive sap loss ("bleeding") from root pressure as it's very late in the winter. I would recommend cutting most off (all on arbor) and leaving some branches if you can.
