As far as productivity is concerned it really depends upon the property. The TTHP and the TT are completely different animals.
The TTHP is an extremely agile high production walk behind. The TT on the other hand is kinda the beast of the two. Bigger engine deck, heavier frame, deeper deck, bigger tires and more POWER.
The TT will do virtually anything the TTHP will do however the TT probably has an edge in all out cutting. The added 1/2" depth of the UltraCut deck should allow it to cut a little taller and thicker grass with out bogging down. Combine that with the added power of the 20hp or 23 hp engine options and it's tough to beat in these conditions. The TT will also hold a hill better and handle a riding attachment a little better in hilly terrain.
The TTHP 52 is available with the 17 Kaw. MSRP is between $5200 and $5300 depending upon electric start or pull start.
The TT on the other hand will range between $6000 and $6400 depending upon which engine you choose.
Let me know if I can be of any further assistance.
The Turf tracer Is a Lazer walk Behind, it shares alot of the same things. to name a few The ultracut Deck,The clutch 200Lb the higher horse power and the caster berrings. Its a great cutter with an attitude!!!
