It's possible that the balancer shafts bushings were overlooked on the overhaul.

What does the dealer say about it?

As previously stated. Install a known working calibrated
pressure gauge.
Drain and fill with straight 50 weight Shell Rotela .
Odds are the dealer rebuild was the economy version. New
sleeves because the owner never changed the coolant.
O'rings , gaskets pand bolt it back together.

Given the age of the tractor and the price/cost/value.
Just install an accurate robust gauge and keep an eye on the pressure. Run T1 50 weight. Install a new oil pump.
Not really worth major input unless everything else is in new pristine condition.
Given the obvious "care" the tractor had had previously. Make certain with a drain and flush that the trans/hydraulic is filled with Hy-Gard. Look for troubles both now and in a few hours trapped in the trans oil filter.
I'll bet the water pump pulley and alternator pulleys are 37+ years old and worn. If the belt is tightened enough to avoid slippage. The alternator and water pump bearings will soon fail.
1-800-522-7448 for the operator manuals. There is a grease fitting or two in vital areas that needs a wee dab now and again.
A $15 de-stroker screw and a coolant heater will ease winter starts. Don't use ether in those engines. They can't handle ether like a two stroke Detroit. Don't need broken piston rings.
