I have turned grass into cylinders!!!
I will get the photos up in the morning. Here are my initial comments:
1) Making round bales takes some finesse! My first one was a cone, much larger diameter on one side than the other. I had a few awkward ones, which won't be in the photographs, but mostly I got the hang for it. You move your baler from side to side on the windrow so that the core forms evenly, then you can pretty much follow the windrow centered.
2) My concerns of pulling a 3700 lb baler + bale with a 3700 lb tractor was a non-issue. It pulls it without a struggle. When the bale gets larger diameter and you hit a mound to go over, I was having to give it some throttle. But, I kept the RPM's around the 1800 range most the time. It didn't feel like I was pushing the envelope on the tractor one bit.
3) A made 30", 3', 4' and 5' diameter bales. After some discussion and head scratching, we decided that the 4' would be best for half our hay and the 30" for the other half. Two people can lift the 30" diameter (the lenght is 46") without too terrible a struggle and they will fit in my front loader. I was thinking of using these for goats, sheep, and other animals who won't eat the big bales quickly like cows would. 48" was really manageable on the tractor, it didn't bog the PTO down; whereas going from 48" out to 60" I had to throttle up a bit to keep things running smoothly.
4) There was one problem with my plans. The 30" bales were not quite heavy enough to always activate the ramp and roll out. So, I either looked at the shadow to verify it rolled out, or I backed the tractor up 5' then reversed it forward and I could feel it roll out. As a last resort, the gate obviously won't close if the bale hasn't ejected, so always check your control box for the green light.
5) Mine does not have the auto-tie option installed. It wasn't hard on me or my neck to look back and manually set the tie points. However, I could see how you would want auto-tie if you were doing over 10 acres per day.
That's about all I can think to say right now, except I'm utterly thrilled that this 'project' has come to fruition. Yes, you CAN bale with CUT's; but remember to be safe and don't run machines out of specs or guidelines. Consider also that the John Deere 4x20 series really blurs the line between a CUT and a standard utility tractor. It's just a monster and I love all I can do with it.
[edit] one more thing, I still somewhat wish I had got the 1740 because the 39" bale length by a 30" diameter would have been really manageable with bale hooks to move around. that gives me options to use small amounts of hay without having to hook-up the spear. But, I think I should regret things less, and be less of an engineer and just keep trucking and make better bales each day!
