Gardner, sounds as if the 4400 is a great tractor but I am getting grief from the budget department about the size of the 7800. Also, my more occasional woods use makes it harder to justify a larger tractor - unless there is great price on it.

I also look at my brother with his Ford 1710 runing a 4" chipper and claims he has rarely felt the need for more power.

Thanks for the numbers on the 4400, I will do some price comparisons between the two.

You are certainly putting in an impressive effort of research and TBN requests for assistance. I have no doubt that you will make the perfect choice.

I have noticed after pouring through a lot of threads on TBN that it is rare that anyone down sizes. It seems that most discussions center around someone upgrading to a larger, more powerful tractor.

However, you are absolutely correct that the tractor should be matched to the property and the jobs ahead.

Tractor size and strength can be translated into different categories. Aside from the obvious space constraints and issues whe working around obstacles and/or buildings, the larger the tractor the faster the job can be accomplished in most scenarios. If it's hauling materials, stumps, tree lengths, brush, boulders, etc. across a large property, the larger tractor will require fewer trips. It might equate to less initial chain saw cutting since the larger tractor can carry heavier limbs and/or tree lengths. The attachments can be larger which also reduces the number of passes, strokes, etc. to complete a job.

Many people are often quoted as saying you can never have too big of a tractor. I agree. This statement has under tows of being realistic, but it speaks volumes to the common occurance of people realizing that they's like a larger tractor than the one they presently own.

We sold our tractor to acquire a more modern one with features that were becoming essential. Our tractor was only 2WD, and it did not have a center PTO. Those were needed upgrades after 7 years of use. We moved from doing jobs around the house area [groomed acreage] to expanding our reach into our many acres of hilly, wooded acreage. 2WD, a center PTO, and more h.p. have become necessary to handle the expanded role the tractor must now serve. Horsepower has become the most important factor in our present search for a new tractor: [and, typically, horsepower = size]. We recognized that our previous tractor was performing at the limit of its capabilities on most projects. It required more trips, smaller bites, and more time.

Ideally, we could use two tractors: a B3030 and a Grand L. That tandem would address all areas of our property from tighter spaces, to open fields, to uneven, wooded acreage. Alas, it is unlikely that I could afford both tractors anytime soon - if ever. For this reason, I'll most likely opt for the Grand L. I'd rather own the larger tractor since I must choose. I am betting that the number of occasions where the tractor will be too big will be far fewer than the number of occasions where I would have preferred the larger tractor.

I could also opt for the B3030 and continue to rent out the bigger jobs to a hired hand who shows up with a huge excavator and bulldozer. That is a very nice option as well. The B3030 would perfectly match our groomed area. Either way, I'll be elated to have a Kubota on hand.

All food for thought ...

Best,
The Gardener

I run a Valby 6" hydraulic feed chipper on my Ford 2120, 35 pto hp. Even then it is not quite enough hp to run full length 5-6" hardwood trees through. When I put the chipper on mt TN, 62 pto hp, I really notice the difference.

Thanks Andy that fits with what dealers are telling me, hp anywhere from four to ten times the diameter equals what can be handled without slowing down. I had thought ten was excessive.

Any hardwood will be saved for firewood so I will be chipping coastal spruce which hopefully needs less hp. Any larger than 6" will get squared off for future building needs.

I run the Jima 6 Chipper behind my B 7800. The 30 HP engine is all I need for this work. Fed a solid 23 foot Sycamore limb through the chipper and the RPMs only dropped by a third. This being the largest & longest solid limb at 6 inches at the base tappering to 2 inches at the end was a deliberate test I wanted to try out on both the chipper and the Kubota. The chipper and the B 7800 have worked flawless on all I can feed it. The engine is superb. I have no trouble getting through tight places in my woods with this tractor. Have had my B 7800 for a year and a half now, with 172 hours. The LA 402 loader & 60 inch MMM also have been flawless.

Cal,

I think the tractor size would depend on the size of the chipper you require to chip your branches and trees. I have chipped a fair amount with mine and have found the info the chipper rep. gave me on the front end was pretty good. He said I need approx 7 hp per inch of dia. for hardwood. I agree with this requirment. I have approx. 40hp to my PTO and I can stall the tractor with a 6" hard maple if the branch is too long and I feed it too fast. With spruce you could get by with 1/2 to 2/3 that horse power. My tractor does not skip a beat with a 6" pine tree. I have plugged the chipper with lots of green needles though.

Good luck,

Jeff M

Ed and Jeff, thanks for the input. I have about 80% spruce and almost 100% of the trees that fall down are spruce. I will measure one next week but probably a foot plus in diameter at the base and a lot of branches in the top third. The rented chipper, with a four cylinder gas engine, did fine up through 6"-7" but slowed down on the needle full tops.

Not sure I am going to be standing there feeding anything much more than 6" trees but I like the larger openings to stuff the tops in. I prefer a 6" chipper but they get expensive and require a more expensive tractor. So I am tying to decide if the 6" is worth the extra bucks for part time chipping.

I also like the B7800 which I am seeing (ME) for 16000 but the previous coments about an L3400 (approx 2200 more) make it very tempting, plus it can run a larger chipper. Maybe time to go look at used again.

With all the talk about signs of inflation, I wouldn't be surprised to see a price increase this winter. Which makes the current 0% financing a very nice opportunity to buy new for the next few weeks.

When shopping for your tractor be sure to consider everything you want to do with it and not just the 1 task. What might be perfect for 1 job might be imposable for another. Keep the big picture in mind. The other thing and this is just my personal opinion. If I have the option of going new or used I will always go new. Tractors can have a rough life in the wrong hands
