The 2810HST is just being upgraded to 35HP, otherwise it will still be the same tractor. I am a dealer and I just ordered more 2810HST models for stock as we are getting low on these. Currently Mahindra still has these in the warehouse and dealers are still buying them at full invoice price, so I wouldn't expect lower prices on these unless Mahindra decides to give the dealers an incentive of some sort.
The dealer network is expanding rapidly and sales are soaring. If you have a good dealer near you, go take a look. If you are in Northern California come take a look at our place, we generally keep 40 or so new Mahindra's in stock.
