First attempt with the new bale spear this weekend was a bust. We knew going in that our 35hp tractor was not big enough to lift/stack the big round bales. Decided the extra cost wasn’t worth it when we considered the HP that’d be needed, and the low frequency of the task (with just 2 horses, we move a roundbale maybe 8-10 times a year).
My work-around was to build a sled that slides very easily along the ground. Before my Glorious Tractor Ownership Era :lol: , I’d position the sled in front of the bale (which is stored on the round), and using well-placed tow straps and our SUV, I can tip the bale onto its end, on the sled. This works, but I was (am!) hoping the tractor would let me place the haybale onto the sled with a little more precision. To do that, I just need to lift it about 2" off the ground.
The hay: Big 5x6’ round, all grass. The worst-case charts say a bale like this just out of the field, would be about 1700lb. And this is last year’s hay, stored under roof, so it’s very dry. I highly doubt we’re more than 1500# now.
The tractor: 35hp, max capacity 1800# at rear PTO hitch, where we have a 49" bale spear with 2 shorter stabilizer spears.
Now, I know that lift capacity goes down with every inch that you add between hitch and the center of gravity of your load, but sheesh, I couldn’t get the bale off the ground at all. With the rear PTO hitch fully lifted, the bale was still in solid contact with the ground, so when I moved the tractor forward, the bale stayed put while the spears just slid out of the bale. It’s not like I was popping a wheelie-- my front end was still on the ground (though certainly a bit bouncy, not unexpected. I can add some ballast to the FEL to reduce that).
I’m wondering if it’s just a height issue-- my PTO arms can’t be raised high enough off the ground to counteract the natural tendency of the bale to deform/sag a bit as it’s lifted. They’re net wrapped and baled tight, but still, it’s not like it’s a rigid cylinder. I could get more vertical lift at the FEL, but weight capacity is even lower up front than at the PTO.
If any more experienced folks see something obvious I’m doing wrong in the above, let me know. Bit of a bummer that it didn’t work at ALL, but I still have my Tip-and-Drag method which works ok.
