A 914A should be a good combination with your TC29D. Be sure to make sure the deck is compatable with your tires. The 914A is made for many NH applications so make sure you order the correct deck and lift kit. Check the bolts often the first few hours and I would encourage you to Permatex the gear box mounting bolts before the deck is mounted (or ask the dealer to). One of the advantages of a belly mount deck is getting in tight spots. If you have a loader and leave it on, that will negate the advantages and add alot of weight to the front tires. Also, think about what tires you use. Ag tires or any non-turf tire will damage turf in wet conditions. We have two tractors with 914A decks and have been pleased with both decks, just keep up on the preventative maintenance.
