I recently put a Land Pride 54inch 420lb box blade on my Kubota B1750 4wd hst tractor. The manual said the weight limit for the rear lift arms are
380lbs so I'm over by 40lbs. I used the box blade to grade my gravel driveway with no problems. When I used it with the shanks down to plow up my small garden (very soft soil) I had no problems except once the box filled up partially and I tried to raise the box blade and it refused to budge. I
backed up a bit so the shanks were not biting into the dirt and that freed up the box.
When I got the tractor back in the barn, lowered the box
blade and shut off the engine I heard what sounded like escaping air and dripping. Hydraulic fluid was coming out from the area just above the pto
spindle where the top lift arm gets its hydraulic power from. Aprox. 3 ounces of fluid came out before the drip stopped. I restarted the engine, raised
and lowered the box blade, shut the engin., No more fluid came out at that time. I checked the hydraulic fluid level and it was in range on the
dipstick.
I was wondering if anyone experienced in these matters can advise me as to how serious this might be and what I should do to prevent any damage to
the tractor. Might I have damaged a gasket? I hope I don't have to get rid of the box blade due to its being 40 pounds overweight.
Thanks for any advise!
