Golden Jubilee vs Ford 2810 diesel

I have both tractors and for some reason the 2810 will run a bush hog a lot better. For example runs the stew out of a BH 286 which is a 6' cutter with 110 hp gear box. Now my NAA or Jubilee will barely handle a light duty 5' cutter with 40hp box. This is comparing both in very thick high grass. The NAA was rebuilt a few years ago has great oil pressure too. Since both tractors have about same hp I'm confused as to why there is so much difference. Any ideas?
 
Well that's what I though also but what I found (and there's not much) says the Jubilee actually has 110 vs the 2810's 101. I'm not sure I believe this though considering how the two perform. Also the 2810 has a 158ci engine vs 134 for the Jubilee. Again makes me feel the 2810 has to have more torque. To my knowledge I've not seen anyone running 6 footers behind the Jubilees but maybe I'm wrong. I guess there could also be something wrong with my Jubilee but oil pressure is great and it runs perfectly otherwise. Just not sure I could ever envision it, even as new, running that heavy built BH 286 I have.
 
I use a Woods 6" finish mower behind my Jubilee and have no problems at all, but I am not cutting at hay heights with that as a rule.
 
You're running mowers with 40 and 110 hp gearboxes on a tractor that only puts out around 31 or 32 hp at the PTO. Hopefully you have a slip clutch installed that will slip way before the 40 or 110 hp marks are reached on those mowers, otherwise the PTO and transmission will not be happy if you hit something that stops the spinning of the mower.
 
The 3 will have more torque, no doubt about that. Otherwise I expect there's probably a bit of an allusion there between the feel of that torque and the gear selections you have as well as the engine speed. The 2810 shouldn't really do much more work than the NAA.

a rebuilt jube should swing a 5 thru anything you can drive over in 1st gear. my 8n surely will.

6' gets down to normal size stuff and a ld mower. i usually save 6' mowers for 172 jobs or 3 cy; jobs.. though my jube has certaintly clipped horse pasture weeds with a 6 with 0 issues.

Have you checked compression on that rebuilt jube? haveing trouble on a 5' mower is disturbing.. unless it was tall lush grass.. in which case.. that really EATS hp...
 
The diesel has much better torque at same rpms in the pto midrange which is where most mowing would be done. We have 860 gasser and 961 diesel and there is almost no comparison between them for brush mowing- not to mention the way lesser fuel use on the D.
 
ine never found anything my jubilee wont handle, i did have to mow one area twice once but that stuff was 2 feet taller than the hood of the tractor, , but it depends on torque and gearing, hp is not the important number on a tractor torque is, most diesels will out touque a comparable size gas engine,example, a 5.9 cummins diesel pickup, and a 5.7 gas engine pickup, both around 185hp back in say 1995, pulling power, there is no comparison the diesel wins by a giant margine, gearing also figures into it, my farmall cub [ 1949] is rated at around 10 hp, but thru torque and gearing it makes a 26 hp rated box store super tractor look, well, just silly
