main frame breaks on NH Boomer 1030 at 400hrs

yes my boomer has a cracked chassis

Hi John509,
This happened in June 2016. I took the Boomer 1030 to the dealer in Nambour Qld (David Evans) who were quite astounded to see it at 400hrs. They called New Holland even though it was out of warranty. It took New Holland 8 weeks to reply and send the warranty manager up from Brisbane (a 2hr drive). He walked in as if he owned the dealership and kicked the tyres and made an offer of supplying a new mainframe but I would have to pay the labour costs to have everything transferred across (approx $2,500).
When the frame finally arrived 4 weeks later (New Holland had 2 frames but could not find them in their warehouse), we were able to see the damage up close. It had broken about 8 inches up from where the main frame attaches to the rear hydraulics and gearbox case. It had sheared directly up from a cut in the frame and where another piece of metal had been welded on in the factory. This weld had not taken and was on the piece of the frame we retained. The cut became the source of the failure of the frame fracturing up.
We have used a small 4' Howard Nugget slasher which I was told by both New Holland and Howard representatives would be ok given it weight and capacity of the tractor.
What has happened to your's if you wish you can contact me directly and I can speak a little more frankly. 0412 733 737

IF you have a 7308 loader on the tractor, that is the issue in my opinion. I had a 1998 model 1925 Boomer with that loader. Cracked the subframe one and replaced it. Later broke the bell housing case where the engine bolts up to it later.

I finally decided the loader is the problem. Those two pins that stick out on either side up front transfer a lot of stress from the loader when lifting weight from down low to the front end of the tractor. That stresses the subframe, and the engine to bell housing point. I was lifting something out of a ditch when the bell housing broke....it immediately stopped the tractor dead as it bound up the flywheel.

That loader is a piece of crap design. Do not attempt to use it for any real kind of work, or you may well break the tractor.
