omc 595 round baler?

are these balers any good? only need to bale about 10 acres a year

Yup became gehl baler. Our 1310 / mf version has been great for a 1000$ baler. Does 200-300 4x5 bales a year.

When new they were good simple fixed chamber baler. That said it would have to be 30 years old. So how good of a baler it is now will depend on past upkeep. Be aware likely no parts support.
I baled with one for close to 30 years and it is in the barn for backup. It will need 70 horsepower and more will be better. Will work best if the windrow is the same width as the pickup. If the windrow is narrow you will have to weave back and forth to get a good bale. If you want any particular information just ask and I will try to answer.

They are a Claas designed baler manufactured by OMC, MF and Gehl in the US. Some parts can be gotten through Claas. Most of the common parts can be sourced from other places. Chains, Sprockets, and bearings are simple to get. Drums can be repaired by about any good machine shop.

They are a fixed chambered baler. Meaning you can only make full bales. They just hold the door closed hydraulically so the rolls compress the hay. To make really tight bales it takes HP. 100 HP plus is best. I have run one with a stock JD 4020 and in heavy hay it was all it wanted. One trick/key to getting good bales with these balers. Do not tie/stop the bale from turning as soon as the pressure gauge shows you have a full bale. IF you are using a tractor you can slow down with then do so for the last bit of hay. The bale turning longer under pressure makes a much better bale. Fi your tractor can not slow the ground speed down then just stop and let the bale turn without taking in any hay. After minute or so you will see the pressure drop as the hay is compressed. Then fill the baler up again and then tie/finish the bale. You will have a good tight bale with a harder outside to shed water better.

This is spot on. With a powershift you can fly along on 10 mph in giant windrows with these things as they only need the power the last 1/8 or so of forming the bale. Slowing down to 2.5 mph or so you can pack another 100-150 lbs of hay in while it tightens up the bale.

With the pressure gauge pegged it will load up a 100 pto hp tractor a bit but makes a good bale with a soft centre that we?ve had less trouble with moisture/ dust than with hard core bales.

I don?t think it?s accurate to say it?s a exactly a Claas design, my understanding is the original design was licensed to vicon, Claas and OMC(later gehl and mf) and they all have that little roller baler icon somewhere on them showing they are licensed. The Claas is built metric and the Omc gehl are sae so many things don?t interchange properly.

Luckily very basic units, average machine shop can fab most of it as mentioned. I think the most common repairs are the pressure manifold thing with the relief valve leaking down, next is the double sprocket that?s down low spitting out the gib key and wrecking the keyways.
