Yeah it took me a while to type that I was on the phone too...
83GMCK2500-How big a plow? We ran 4 bottom JD in furrows no problem on ours. Dad ran a 5 bottom MF in furrow on the 4450 a bit and it pulled it ok but it was front end light. I made some brackets to bolt on the sides of the weight bracket so we could add 5 more on each side. That helped a lot. Thing was though the leverage of that longer plow was way hard on the rockshaft and we ended up having to do the seals on it after running that plow. Even with the weights it could throw the tractor around some.
Then I bought a on land 3 bottom MF parts plow and swapped all the stuff over from the in furrow and pulled 6 bottoms on land with the 8100. Much better. The MF plow is kinda neat in that it is 3 bottoms and then you keep bolting frame sections on to make it bigger.
We hardly use it now though except if we really need to plow stuff down. Use the soil commander disk ripper instead. Thinking about getting a strip till machine now. I miss plowing but I don't miss the water running off the field.
I'll have to ask my dad. I was small enough to sit on the armrest (lowered) of a JD of that series and ride comfortably...feet didn't reach the floor of the tractor. Oh, both of ours and my uncle's were 15 Speed Powershifts. Gawd I hate the 3-4 cluster change at 1,800rpm running that damned baler. NAR, have you seen those auxilliary fuel tanks that mount above the main weights? That is where my dad got the idea for the double-stacked weights, and where he put them.
For referrence my dad had:
310 Backhoe
2020
4230
4240??? (I'll have to double check)
2x4450
4850
+ a couple of ones around 4230 size for other field work
My uncle had:
4020 (damned fine tractor) Cultivator or Freeman 200, also had a 3-wheel Darf rake on the front.
4230 (Model 8827 Allen Rake)
4040 (Model 8827 Allen Rake)
2x4440 (Freeman 270 Baler)
4450 (Initially another Freeman 200, but graduated to Auto Align 4SR Bale Scoop)
4455 (Moved the Freeman 200 to this one because this tractor only had 2 remotes:mad2

4555 (Hesston 4790 3x4 Baler)
4960 (Hesston 4790 3x4 Baler, this tractor would give me half a stalk everytime I started it up. What a big beautiful bale making machine, I loved it. I know the 60 series is frowned upon for the frame length, but it made a helluva baling tractor.)
