Re: Spra coupe 7660

Yes. Very maneuverable machine, light weight, good visibility, good on fuel. Booms are light but they are strong enough (won’t take the abuse a Rogator boom will). Machine is capable of all kinds of acres as long as it is tendered good. The 7650 had some issues but that seems to be in the past. 50" of clearance with mechanical drive is a good thing. Transmission takes a bit to get use to. Nice Rig !

Re: Spra coupe 7660

The only real trouble spot I have found after 14000 acres is the front fender mounts are a joke. They vibrate so bad when you turn they destroy themselves. It is a little under-powered, and loud in the cab but it will get a lot of work done. Overall a nice machine. I had two GVM Predators before this and have not had 5% of the problems with the Spra-coupe.

Re: Spra coupe 7660

7650 coupe had/has a solid front axle. this put to much stress on the front suspension. there was also a small problem with the fuel pump it would tend to drain fuel back to the tank after an extended amount of down time. some guys put a inline pump that would pressure the fuel pump upon key power, this made a great difference during start up.

when the model changed to a 7655 Agco made the front axle pivot in the center which removed alot of stress from the suspension.

By the way, the Rogator boom and the 7000 series coupes booms are made from exactly the same plan in exactly the same factory... The Rogator sprayer has not changed in 15 years, the machine is an antique.

Re: Spra coupe 7660

I have a 7650 and I think the 7655 is the same except it is 4 wheel drive. The pivot points were changed when the 7660 were built. The 7660 is not as rough to ride in as the 7650. Other than being a little on the rough side the 7650 has been a great machine well built and easy on fuel. I have never had problems with the fuel pump

Re: Spra coupe 7660

the 7650 has a pivoting front axle, the 7655 has a solid front axle and hyd rear suspension other wise the same as 7650, 7660 has the suspension upgrades of the 7655 but runs a tier 3 engine. all 3 were available in 4wd.

Bought one of these machines new a couple years ago. Anyone ever had trouble with the booms chattering and eventually breaking?
