Long lane tractor in Elizabethtown PA is a NH graveyard and they had a few TC's in that class last time I checked. Give them a shout couldn't hurt.
I've called called all of the suppliers listed so far in this thread (and a couple of others), Long Lane is the only one with one in stock. The others mentioned (plus a couple more mentioned by my tractor mechanic friend) all said No, nothing in stock. A couple of them are searching around to see what they can find.
I do have one question: The part number which showed up in the All State Ag link posted by
@Sportsman762 for a NH TC33D is: SBA320111115 (They list this part as fitting a number of NH Tractors: Boomer 2030, Boomer 2035, T1510, T1520, T2210, TC25D, TC29D, TC29DA, TC30, TC31DA, TC33D, TC33DA, TC34DA, 1520, 1630, 1925)
Wenger does not have that part in stock, but shows that it is a newer version of the part number for a NH 1630 tractor, part # SBA320111440. The price was reasonable at $850. When I asked, can you confirm that this will also fit a NH TC33D, he said he was not certain, but when he looked up the part ending in "115", it showed a reference to the older SBA320111440 part from a 1630.
I want to make sure there is nothing about the older part that would prevent it from bolting on to a TC33D. Can anyone confirm that the older -440 part will also fit a TC33D? If it does fit, is there any reason to hold out and keep looking for the -115 part? Perhaps they upgraded the design to make it more robust in the later version.
I may have to make a call to my dealer or NH to check, but thought I'd ask here first.
