I have been out of pocket. Current price now on this machine has dropped to $3800.00 firm. I'm going to take another long look at it in the next few days.
The TY395 engine uses two different filters, the only difference is the thread. One is metric and the other is SAE. Mine is SAE and uses a NAPA 1515. You might have to take the old filter in to be sure. Also, Tommy at Affordable Tractor has an adapter available to convert the metric filter head to SAE. He also stocks the OEM filters.
For the engine, a quality multi grade (15w-40) motor oil that meets CJ4 or CI4 or CH4 standards. ie Chevron Delo, Shell Rotella, etc.
For the transmission, a quality multi grade EP gear oil (80w-90) that has an AGMA listing.
For the final drives, a quality multi grade EP gear oil (85w-140) that has an AGMA listing.
For the hydraulics, I use an ISO AW 32/46/68 multi grade hydraulic oil exclusively, however, an ISO AW 32 or 46 straight grade will work as well.
