In reference to your comment:
"Putting that 2840 on a dyno and measuring fuel use is the only way to really know. The seat of the pants makes inaccurate dyno."
It does NOT necessarily work that way. I think a farmer that knows his tractor can certainly tell when it's using more fuel than ususal - or more than it ought to for certain tasks - as compared to other tractors.
I don't recall ever seeing a 2840 myself - why I don't know. But, we sold a pile of 10, 20, 25,26,27, and 29 series tractors - 40s, 50s, and 55s. I left the Deere dealership when we were selling the 55s new.
Many were using the CAV rotary pumps instead of Stanadyne's they copied - and many that we sold new got turned up at the buyer's request. Yes, we had a dyno - it was NOT a requirement, it just saved some guess work and jerking around. We'd often run them at full load for an hour to make sure there were no cooling-system issues.
And - about buying a bigger tractor and doing twice the work. Well yeah . . . - but usually, that bigger tractor will be a dog when it's used for low-horsepower work - including the newest ones.
About when Deere introduced the 40 series tractors - it was discovered that some models responded extremely well to fuel turn-ups as compared to older tractors. And, that became more true with the 50 series. In some models, Deere would use the same engine in several tractors of different horsepower ratings -and the fuel-delivery was the only major difference (and better cooling systems at times).
I'm sure we turned up hundreds of tractors - and I'm know other dealerships did also. Subsequently, I assume some are still out there - especially with CAV pumps - since they are built better than the Stanadynes and may have never been off for a repair-job.
