i've been cutting milo this week with my new 2388. using a 30 head the heads are in the leaves so i have to take alot of them. my question is 3.5 mph is all i can do. the rotor speed just falls off after that. is this normal for a 2388. the dealer says i can turn it up 40 horsepower. has anyone done this and how much does it increase fuel usage

If the rotor speed is falling off but the engine isn't, you don't have a hp problem but probably a weak spring in the driven pulley on the rotor drive.

If your engine speed is going down too then adding some hp wouldn't hurt. There are a couple threads on here about adjusting the pumps. Do a quick search and you'll find them.

Do you have a standard rotor, and are the plants still green? Last year we had an irrigated field that we cut while it was still green. It was making 150+ and I couldn't go any faster than you with an 853A. When I got to some 50bu dryland after a freeze I was doing 5 and not loading the engine very hard. From my limited experience I'd say your machine is about right, especially if you're taking a lot of leaves.

We'll be using the 36ft header this year. Everything will be cut after a freeze, so I don't anticipate any problems.

it is a 06 with afx rotor and yes the engine and rotor come down at the same time. i was running 6 mph in 150 bu corn with no problem but when i put the 30 ft table on i was dissappointed. it could be the green stalks,, they are plenty wet

I have a 1990 1680 and have been cutting 100 bushel milo that was single crop. The head was dry but the plant was still green and it really took a lot more power just simply because of all the green coming through the machine. I would guess if the head is down in the leaves and your having to run all this through it will take a lot more power. You probably don't have a power problem.
