GUIDE: Shopping/Sizing A Tractor (development version)

I have been revising this screed for three days.
I seek outside criticism and input.
FIRE AWAY!


The best way to shop for tractors is to determine your tasks first, then determine how much bare tractor weight you need to SAFELY accomplish as many of your tasks as possible. Bare tractor weight is a tractor specification easily found in sales brochures and web sites.

Hillside work demands more tractor weight than flat land work. Heavier tractors have greater wheel spread making them more stable. Heavier tractors have larger wheels and tires better able to bridge holes and ruts without the tractor rolling over. Larger wheels and tires provide a much smoother ride over rough ground. Heavier tractors have greater inertia to resist rollovers when moving heavy loads in the FEL, the most hazardous of routine tractor tasks, especially hazardous on sloped land.

For most tasks greater tractor chassis weight is far more important than tractor horsepower. This tractor fundamental is difficult for people new to tractors to comprehend.

Shop your weight range within tractor brands. Budget will eliminate some choices.

Tractors under 3,000 pounds bare weight are offered in one basic configuration. Tractors over 3,000 pounds bare weight are generally offered in a utilitarian configuration and a deluxe configuration, on a common chassis. Deluxe kit enhances productivity and operating comfort ~~~ but you have to pay.

I like to spreadsheet tractor and implement specs, often a revealing exercise. I have a column for cost per pound.

It takes a 50% increase in tractor weight before you notice a significant tractor capability increase. It takes a 100% increase in tractor weight to elicit MY-OH-MY!

Selling a used tractor is easy. Selling multiple light implements in order to buy heavier, wider, implements for a heavier tractor is a pain and often a big hit in depreciation. ((Ask me how I know.)) Many who buy too light tractors buy too light implements.

A quality dealer, reasonably close, is a priority for me; less so for others, well experienced with tractors, who do their own maintenance. For most new to tractors a quality dealer, reasonably close, available for coaching, is essential. My kubota dealer is six miles away.

Horsepower is a primary consideration only operating PTO powered implements.

BUY ENOUGH TRACTOR.​

Excellent guide Jeff. My only input is that there are some deluxe tractors under 3000lbs bare tractor weight; the Kubota B 50 series and Yanmar YT235 to name a few.

Thank you for working up this excellent guide.

Very good summary Jeff. I am right in the middle of this process trying to figure out how much I need, vs. budget, vs. how much I want. Those three items seem to not get along very well in my life. Maybe the spreadsheet will work. I frequently find your in put very helpful.

I make spreadsheets for everything. Quite enlightening! Got one going now for my future tractor & implements.

DRAFT REVISION

Tractors under 3,000 pounds bare weight are offered in one configuration. Most, such as the high volume Kubota standard L series, are prosaically equipped to hit competitive price points. Others, such as the Yanmar YT235 and Kubota B2650/B3350 series, are better adorned. Most tractors under 3,000 pounds bare weight are used in residential applications on one to five fairly flat acres. These "residential tractors" fit in a typical garage.

Tractors over 3,000 pounds bare weight are generally offered in a utilitarian configuration and a deluxe configuration, on a common chassis. Deluxe kit enhances productivity and operating comfort ~~~ but you have to pay. Many are too tall to fit in a typical garage, even with ROPS folded down.

My thinking is to keep this guide to less than one page, so personalized recommendations relative to specific tasks and situations can be inserted toward the bottom of the page.

"In my opinion neither Kubota L2501 nor L3901, both with a bare tractor weight of 2,600 pounds, has enough weight to accomplish your hillside tasks SAFELY. You need a tractor of whatever brand with a bare tractor weight of 3,500 to 4,000 pounds.
In Kubota this would be the utilitarian MX series or the superbly outfitted 'Grand L' series. Same heavy chassis; different kit.

As usual, your thread makes sense. I wish the manufacturers would settle on common terminology for frame size. That more or less also correlates to weight and tire size. Here is how I would state it...

Acreage............. Kubota ..........Deere ......Frame Size
1-3 acres ..............BX................1xxx.......SCUT
3-5 acres,..............B01..............2xxx ......Small Frame CUT
5-10 acres.......... L3X01............3xxx ......Mid Frame CUT
10 acres+........ L Grand 60........4xxx ......Large Frame CUT

 

[jeff9366]

I do not comprehend BO1 and L3X01.

I like your categories but I would substitute Light Chassis, Medium Chassis and Heavy Chassis for Small/Mid/Large Frame to keep consumers focused on researchable WEIGHT.

WEIGHT is easy to determine and shop. Your Small/Mid/Large Frame descriptors rarely appear in tractor specifications.

I like your inclusion of Deere models. Deere's tiers are clearly more understandable to the inexperienced, relative to Kubota's nomenclature. It is all I can do to keep current with Kubota ~~~~~~

 

[airbiscuit]

I agree that Deere's nomenclature is easier to follow. I was using Kubota B2601 vs L 3301 for small vs mid chassis example. Weight is a good differentiator, but the diameter of the wheels and tires also makes a big difference. That also seems to correlate with chassis size. Are you thinking about creating a master guide spreadsheet?

I like it..

The only think I would say on the dealer quality and local is that it is especially important if you use your tractor to make a living. If you do not it is less important IMO.
