3PT. weight limits
I have a little kubota b7510 at my farm. I think the front end loader has around a 400 lb. limit, it is a 272 I think, but what about the 3 point lift?,. My box blade, cultivator, brush hog weight around 400-500lb. each, but what is the limit?. And is there a safety valve that would prevent you from blowing the seals?. New to tractors and could use some advise.

Re: 3PT. weight limits
FWIW, the Kubota specs list 3 pt hitch capacity for the hydro version of the B7510 at 615 pounds at lift point and 480 pounds at 24 inches behind lift point. I run a woods GB60 box blade that weighs 495 pounds on my B7610 (which has the same lift capacity as B7510) and I have not had any issues to date.

Re: 3PT. weight limits
Pretty much every hydraulic control valve has a relief built in to prevent damage to the pump and seals, etc. This includes the 3ph control.

Re: 3PT. weight limits
I wouldn't count on -every- hyd valve having a relief.. but depending on how it taps the tractor system, the tractor system may still have a relief in line.
Dang.. those are some low lift numbers.. how much does that tractor weigh? soundguy |

Re: 3PT. weight limits
That can't be right. My little tc 21d is some 1200 lbs. rear lift.

Re: 3PT. weight limits
I agree.. they look real low. At those #'s.. i don't see how it can use most standard 3p implements. My little yanmar 1700 totes a 30" dirt scoop, and I know it must weight at least 200#.. maybee 225#.. I can lift it filled with dirt.. heaped over.. and I'm guessing total weight is nearing 750+ #.. all I need is front weight.. lift don't even groan at all.. yanks the scoop right up.. and that is a little ~19hp tractor

Re: 3PT. weight limits
It looks like Peter got his kilograms mixed up with his pounds. The 3ph on a B7510 has a lift capacity of 1356 lb at the lift point, 1058 lb 24" back. The 615/480 capacities are for our friends around the world who use the metric system.
