I've never looked at or dealt with a 4750, but the baler should be designed to run at either 540 or 1000 RPM PTO speed from the tractor. At this rated input speed you should end up with the specified strokes per minute. Most tractors had the engine RPM at which you get the rated PTO speed listed somewhere (sometimes marked right on the tachometer). If it sounds like it is running much faster than you expect, make sure you aren't running a 540 RPM baler at the 1000 RPM tractor PTO speed. Most tractors can't do this without some tampering by the operator, but I have seen some that you could switch the PTO speed without swapping out the PTO shaft.

All this being said, our old JD 336 does not like to be run at a full 540 RPM (starts missing ties), we usually back off a couple hundred engine RPMs on the tractor and it will bale all day with no problems.

 

Don't know anything about the 4750, but I have had 3 NH sq balers and all of them have done the nicest, most consistent job at about 1900rpm engine spd and decent windrows at about 3 mph ground speed. I have gone faster, run it faster etc but it is most consistent at the stated speeds with 5 different tractors with different hp ratings.

 

hesston 4750

The inline Hesston balers put up nice bales.

What you ask should be in the ownern manual. If you do not have one your Hesston Dealer should be able to get one for you.

I think the JD remark is interesting, What I know of NH is we run it at the highest strokes per minute listed in the operators manual.

Factory Rep at a seminar said to do this for higher capasity and for a better momentum on the plunger.

What you do is find the best engine RPM s for your baler, and adjust your ground speed by changing rears.

I go up a gear when the baler ties at 18 strokes and drop back a gear at 12 strokes per bale.

If you have a hydro drive that is great, just keep adjusting your ground speed to have a bale for each 15 strokes.

I prefere to bale in third gear as that is where the hay feeds into the baler the best. I have baled a lot in first gear as well as in sixth gear. Actually have baled in seventh gear but the bales bounce when comming off the bale chute. Not good for picking up with a bale wagon.

I shoot for a 55 lb 34" long solid bale. I keep a tape measure with me and I get off and keep trac of the bale lengths. While I am on the ground I check the bale for weight.

Isn't the 4750 a big square baler (3'x3')?

 

Yes I read what I expected to rean and answered accordingly.

It is still a good answer but just for small square bales.

 

OP's baler is a 3x3. Can't imagine that it is 540 but I know little about Hesston. I run our mid size New Holland by the monitor indicated strokes per minute, and I always need to run about 100 engine rpm over rated pto speed to get rated baler speed. Just for fun, rated plunger speed on a New Holland D1000 2x3 is 46 strokes per minute.

 

Yes, this is a 3x3 square baler. I have both owners and service manuals. Strokes per minute are 41. Baler is a 1000 rpm. I guess when I start using it I will find the sweet spot.

Depends on the tractor though, 1900 on a Cat 3208 is about 2/3's of full throttle, pto speed is at 2800 engine RPM, my perkins run at 2200 for PTO speed, my 1855 is 2400 engine rpm for pto speed, my 1600 is around 1700 rpm for PTO speed.

 

My tractor is 2100 rpm for pto speed at 1000. Maybe I'm just used to 540 rpm . Ill check strokes per minute wheel I start baling in about 10 days. Thanks for the info gents.

I agree. Don't remember pto speed for all, but I am guessing around 2100-2200. All were deeres. I am running under "tractor" on my JD6100D 100hp and it does great, and just feels like the machinery isn't being beat to hell.

 

Yup, common sense goes a long way in keeping equipment running. A lot of times it's eyes and ears that works the best.
