Nice tractor..They are actually 72 HP. It's the previous 7A 5600 that is 68 HP. They were a gutless tractor except for the PowerPlus model that gained the 6600 engine. The 5610 was a better improvement over The 5600. The smaller 4600 & 4610 could run rings around the older 5600.
In Italy I had a 5600 with 74hp logo on the front, was it the 3,8 or 4,2? Now it has a 4,4 engine (cnh)because a lot of years ago it had a water fall in the cylinders and it had been replaced. His power now is around 90 hp
@@riccardo3212 Your 5600 was the PowerPlus model. The very last run off the 7As got a power increase between 1980 to 1981. The 3cyl tractors stayed the same, but the 4cyl models gained power. The 5600 inherited the 6600 engine going from 68 to 78 Hp. The 6600 went from 78 to 86 Hp. The 7600 went from 97 to 103 Hp. The later 10 Series 6610 and 7610 tractors then stayed at those power figures also, but the 5610 dropped down to 72 Hp. .
@@IncredibleClassicTractors if you look at 0:48 there is 4,4 written on the engine (sorry for my bad english). This is the only reason for me to say that is 4,4 but i’m not 100% sure
