With all of the talk of grapple weights I never have seen anyone mention the weight of a bucket either standard or heavy duty bucket.

Well.... some time ago I tried to figure out what all I have on board when loaded on my trailer, what it weighs and how it is balanced... below is my mostly complete calculations... Lots of numbers... maybe some will be of interest to you.
-
1.[FONT="] [/FONT]Flatbed bumper hitch trailer, 18’, hauls tractor/FEL/3PH attachment as needed. Manual winch at front, ramps pinned to sides and it is at its maximum load capacity for 2 xx lb axles. I haul tractor maybe 5 times a year else I’d need a better set-up. Pay load trailer carry weight needed is:
a.[FONT="] [/FONT]424 lbs measured 72” L2240 round back skid steer heavy duty bucket ( manual says 322 lbs). Specialist says shipping wt is 396 lbs, including 1”X3” planks for shipping, but this does not compute.
b.[FONT="] [/FONT]50 lbs quick attach, L2232A, best estimate from Kubota specialist.
c.[FONT="] [/FONT]139 lbs measured John Deere toothbar. Note I don’t have the optional edge, 45 lbs says Kubota specialist, because it is exclusive with the toothbar.
d.[FONT="] [/FONT]206 lbs measured Kubota QA hay spike.
e.[FONT="] [/FONT]52 LBS measured for long hay spike boom only.
f.[FONT="] [/FONT]1157 lbs LA 853 FEL frame says manual (1186lbs is shipping wt. including grill guard, under tractor frame, no hyd fluid, no QAttach coupler, says specialist )
g.[FONT="] [/FONT]15 lbs for 2 short pipes inserted into FEL QA pivot point crossbar.
h.[FONT="] [/FONT]24 lbs for 2 short axles inserted into FEL QA pivot point crossbar. Long axles are 29 lbs for two.
i.[FONT="] [/FONT]10 lbs front bumper, my estimate, I had welded on.
j.[FONT="] [/FONT]80 lbs 1 front weight, measured.
k.[FONT="] [/FONT]48 lbs for 2 round PVC pipes inserted into FEL large cross brace pipe for holding chain and 2 20 ft logging chains.
l.[FONT="] [/FONT]100 lbs estimated additional on board load (chains, diesel = 7.1 lbs*10 gal, tools, etc.)
m.[FONT="] [/FONT]4090 lbs (HSTC) from the manual: L 5030HSTC tractor, 4wd, cabin integrated ROPS. I guess this is distributed 40% front, 60% rear, thus 1636 lbs front, 2454 lbs rear. Plate under seat talking about ROPS says 4638 lbs reference weight, which Kubota specialist suspects means what the ROPS is qualified for, not weight of tractor. Shipping wt of HSTC tractor is 3540 lbs without tires or rims says specialist. I have been unable to get a better definition of what reference weight actually means.
n.[FONT="] [/FONT]200 lbs, operator, measured
o.[FONT="] [/FONT]1030 lbs rear tire fluids, 515lbs each, liquid filled, says manual.
p.[FONT="] [/FONT]833 lbs 3PH hay fork + carry all + Pat’s system + typical tool box load + 2 bolted in weights, measured
q.[FONT="] [/FONT]593 lbs extra weight, (measured) (3*80 weights + (218 + 105 concrete weights + 30 bucket of rocks) on platform for heavy FEL load.
??? 8595 lbs total, unloaded bucket. 3485 lbs front, 5110 lbs rear = 40%, 60%. So, front tires are at 3485/2/3500 = 50% of max tire capacity. Rear tires are at 5110/2/4400 = 58% max tire capacity.
2.[FONT="] [/FONT]Tractor weight distribution should be 60% front, 40% rear (G1235 Tractor Tire and Ballast Management, MU Extension ) for good tractive efficiency with 4WD/mounted implement when pulling an implement thru the soil. When lifting max with FEL I’m not pulling a soil engaging implement. Nevertheless, I really load the rear with weights. I look at the tractor as a see-saw. Either the front wheels or the rear wheels are the fulcrum. If rear wheels are very light, entire weight is on the lighter front axle. And if front end is very light, then she’s about ready to flip backwards. When moving under load, if the weight distribution is not right I get a “rocking chair” motion, front to rear, of the tractor that tells me to change weight or be more careful/slow. My weight distribution, ignoring moments of arc, calculated, not measured, for a FEL lift is:
a.[FONT="] [/FONT]With empty 72” HD round back bucket attached:
[FONT="] [/FONT]i.[FONT="] [/FONT] Front = 8595 lbs total, unloaded bucket. 3485 lbs front/8595, = 40%. So, front tires are at 3485/2/3500 = 50% of max tire capacity.
[FONT="] [/FONT]ii.[FONT="] [/FONT]Rear= 5110 lbs rear = 60% of load. Rear tires are at 5110/2/4400 = 58% max tire capacity.
b.[FONT="] [/FONT]With only Quick Attach, no bucket, but lifting 2800 lb concrete culvert
[FONT="] [/FONT]i.[FONT="] [/FONT] Front = 3485-322+2800 = 5963 total front weight. Total weight = 8595-322+2800 = 11073. Thus front = 54 % of total weight. Tires are at 5963/2/3500 = 85% of their max capacity.
[FONT="] [/FONT]ii.[FONT="] [/FONT] Rear = 5110/1103 = 46% of total weight and 5110/2/4400 = 58% of max rated capacity.
So, rear heavy when traveling with unloaded bucket but some front heavy when lifting max concrete culvert weight.
Just traveling without front bucket the distribution is front: 3163/8273 = 38% and rear = 5110/8273 = 62%.
This calculation matches my “seat-of-the-pants feeling when driving with and without bucket and or front load. Net: balance is always shifting depending on the FEL load, its height, etc.
??? So, all we have to do is add a little weight to the rear to take weight off of front axle and wheels when heavy FEL lifting. The moments of rotation are too complex for me to consider, so for a static load and targeting a load where 5963 lbs in front =
???? Well, I don’t have that laying around, so just add extra heavy stuff to rear carryall and go very slow in hopes I avoid damaging front axle or 4wd gearing. Calculation ignores both front and rear rotational leverage forces because weights are not directly over fulcrum.

I have not weighed mine but the bottom is 3/4 " steel. Sides are 3/16". One heavy sucker.

You will note that my HD bucket, quick attach and toothbar = 613 lbs, empty.
You WILL want a LOT of weight to counterbalance this. That's what I did all the calculations for. Note I have tires filled and lots of weight hanging off of 3PH .... and, every bit of it is needed, my opinion, when operating fully loaded. I can tell when I'm properly balanced.... If weight distribution is OK.... going down the ranch road, loaded bucket is reasonably smooth... if light on rear, then it's a forward/reverse rocking motion... feels like tractor wants to take a nose dive.. so, I slow down, lower load and add rear weight soon as I can.
