In my neck of the woods in NWIA I used to pull a 5 shank Deere 910 ripper 10" deep with a 1086 running 150 HP at a shy 5 MPH but in my view it was brutal on the tractor. In the low heavy ground I'd be down to 3 MPH or even less. The 1086 was still a 135 horse tractor and that's what it was built for. I'd think a 4430 would be about the same. Today I pull that same ripper with a stock (I think) 4650 and it's a lot better match. It'll do 5.5-6 mPH in tough black ground at 12" deep and the tractor is stable as a rock. I've only had the front end up twice with only a medium sized rock box for front end weight.
Not saying you shouldn't pull 5 shanks with a 4430 but a ripper like mine is unforgiving and I just don't think a 135 horse tractor is generally built tough enough to take it in the long run. The harder the ground, the deeper that ripper wants to suck in. If the two 11Lx15 gauge wheels aren't pumped up to 45 psi they squish too much and the ripper will suck down more than you want it to. The lighter the ship you have in front of that anchor, the harder time you'll have controlling it. Jim

Today's Featured Article - Oliver 550 Purchaser Checklist - by Greg Sheppard. Pound for pound the 550 is better than anything I've seen. It has great power for its size and can really hunker down and lug. Classified as a 3-bottom plow depending on soil conditions. I personally don't think it can be beat for a utility tractor in the 40 HP range. They are extremely thrifty on fuel, at least my DSL is. Most drive train parts are fairly easy to get. Sheet metal is probably the hardest thing to
