The TV-62 and TV-62M are Bulgarian ARVs built from T-62 MBTs.
The following can be found on various user-loaded sites:
"TV-62M - T-62M main battle tank converted into an armoured recovery vehicle. This vehicle is composed of a T-62M hull with a modified T-55 or T-55A turret which was cut in half and it's the upper part was bolted onto the hull in the 6 o'clock position. There's a large winch and a snorkel mounted on the rear of the hull. In TV they were called "tractors for tanks"."

From a more 'reputable' source:
TV-62M ARV
In 1988, Bulgaria took delivery of 150 T-62M MBTs armed with a 115 mm gun from Russia. Due to a number of problems, understood to be concerned with the 115 mm weapon system, these were soon withdrawn from service.
Some of these T-62 MBTs were subsequently converted into the recovery role and designated the TV-62M.
The modifications included the removal of the three-person turret, which was replaced by the fixed upper half of a T-55 or T-55A tank turret which for this role had the 100 mm weapon removed and the turret facing the rear.
The two cupola hatch covers have been retained and a 12.7 mm DShK machine gun is mounted on the cupola. On the left rear of the hull, above the exhaust outlet, has been located a small winch. Tow bars and other equipment is carried.
