Weight Restrictions

carpetfarmer · Jul 12, 2016

Reading Dustyah's post about Too Much Weight got me thinking about my own ongoing project. I know tractors have a maximum weight rating, but what exactly does this entail? A tractor can be too heavy in regards to what (field work, traction, hp-weight ratio...)?

What problems are associated with being too heavy? Of course, short of way overdoing it and blowing out front hubs and spindles, snapping axles, etc.

I'm sure it depends greatly depending on the application, but what is the fudge factor with the specified max weight?

Think of your tires as big black slip clutches that protect the driveline from hurting itself. Add too much weight and it can tear itself up, especially in lower gears. Later on, Case recommended that if you couldn't pull something at 5mph, you shouldn't pull it.

You are correct.....didn't the Case Rapid Farming concept come out with the 90 series to keep speed up and relieve torque on the tractor rearend.

There was also a Max weight rating that the ROPS structures would safely hold during an upset.

you are Correct Steve,, Here when the 1270/1370's came out we as a dealer strongly suggested to use the same equipment the customer already had for their old tractor,, many of those we dealt with had bought 1030's from us, by running faster you covered more ground than before and most times as much as you could with a bigger implement and you reduced component wear Big time, as you see in the one pic Bill was thinking on these lines long before the 90 series came out

According to tractordata my 1190 is listed as shipping at 4620 lb and having a max weight capacity of 7000 lb. I won't be doing any "heavy" traction work when fully loaded, but in the winter months by my calculations it will be flirting with that 7000 lb mark. When pushing snow there will be some slipage and some weight will be lost on the front end because the plow will be sitting on the ground, so it shouldn't be an issue but like I said, it will be flirting with that 7000 lb max weight capacity.

Tractor - 4620 lbs
Front Weights - 3x 79 lb = 240 lb
Wheel Weights - Unknown
Snow Plow - 600 lbs (as I recall from talking to the manufacturer)
Ballast Box - iMatch Ballast Box w/ Sand = 616 lb
Steel Plate - 580 lb
Me - 200 lb

Total Weight (short wheel weights) - 6860 lb give or take 100 lb for guesstimation.

P.S. - Does anyone know what those rear wheel weights might weigh or what they came off of? Cast into them is - BW401A D22T

Yup. You folks are all correct about the Case statements at that time. I had 30 series Case on the farm then, I really liked them, and also 1 tractor of a different color, built in 1963 that had factory installed front assist. It would outperform the Case tractors in our normal daily uses in every way. So, at a Wis. Farm Progress at that time I questioned the folks at the Case display when we could expect powered front axles, was told we would never see a Case tractor with that feature as that concept was a total failure. Not needed except over 200hp. At that time I realized too many engineers(for most manufacturers) had no clue to real life on the farm. Dale
