NI 5212 disc bine.......opinions?

Going to go check out a used NI 5212 discbine that's coming up on a local auction close by. It's a 12', side pull discbine. Supposedly the cutter bar has been rebuilt.

Just looking for tips on what to look for when checking out the cutterbar and gearbox on one of these, or any other discbine for that matter. I kind of had my heart set on a center pivot 10-12' machine, but the side-pull 5212's seem to be a lot more prevalent around here. I've heard a lot of good things about the New Ideas from a durability standpoint, and from being relatively simple to work on if something does go wrong with the modular cutterbar and shaft drive gearbox.

There's a Gehl 2412 on the same auction. I've run a few of these before and liked them, but have heard the cutterbar's are a bit more difficult to repair if problems occur.

I know buying a used discbine is playing with fire, but I really can't afford to drop the money required even for a new 9' disc mower.

I run over 30 acres of my own hay annually, and have somewhere in the area of 40 acres of custom work, which might increase, so I think a bigger discbine is justified.

Any thoughts you guys have are appreciated.

I picked up a Case IH 3309 this summer, same thing as the 9 foot New Idea (Case IH had New Idea make there mowers at the time). Had to fix one of the turtles (bolt was loose) but after that it ran fine. I'm going to check the grease in each cutter section before I use it again next summer.

The only downside I've heard about the cutterbars is that the hexshaft that runs accross and drives the cutter sections will twist after awhile and it makes it real hard to pull the sections apart.

Hope you make out good at the auction.

I dont know how many acres you are cutting but in my area the 9' discbines are going pretty resonable. The 12' and 14' are what all the "big time" guys want. Only the amish and the part timers want 9'. I was at a sale the other week and 2 deere 9' brought $1700 each. They werent shed kept but that had a fair amount of life left.

First check to make sure discs are actually at right angles to eachother to make sure one of the assemblies hasnt jumped time and to give an indication of gear tooth wear inside each unit. Then check free play in adjacent discs. While holding one try to wiggle the ones on either side. Shouldnt be more than a quarter inch of play. If there is the shim packs need changing or the gears are worn out.

If you get it, I'd open the cutter bar and check the grease level in each unit.

I'd love to know how it checks out and what it brings. Been wanting to upgrade a little bit with a longer bar (never had but an 8 footer, but I am running two of them). This year they've got to cut a little over 300 acres with half of that two cuttings and half alfafla at 4-5, plus whatever custom work comes along. But, I priced a new 12 foot Deere (with the way our ground lays a 12 foot bar is about all you want to keep from scalping spots) at a shade over 18,000. Thats too much for me.

Thanks for the tips. Auction is on the 17th. I'll at least let you know what the discbines go for if I don't end up spending some money myself.

Ditto on what kyhayman says about checking the gearboxes. It"s an annual thing- take off the turtleback (what I call them- you"ll see why), unbolt the head, refill with proper grease, and add/remove shims to get correct gear lash. You can compensate for a twisted driveshaft by resetting the gear, so all cutterhead tops are square with the machine. Make sure you locktite the four bolts that hold the head on, since tip speed of the cutters is about 160mph or more. Than can go through the rolls!- but may strip the threads of the ($$$) box below.

Had the 9 foot machine, the 5209, for over a dozen years, son has had it for about 5. He rebuilt the cutterbar this summer. 5212 likely has the better gearboxes- made a bit heavier and attached differently- an improvement.All in all, was very satisfied with the NI.
