Questions about tractor rutts.

[ArtVandelay]

Hello, I am new to these forums.

I have about 11 acres of flat/rolling land in the pacific northwest, 9 acres pasture and the rest trees. A lot of the soil is clay. The clay gets softer and wetter during the fall/winter but it becomes really hard during the spring/summer. There is reed grass on the land also. The reed grass can grow to 6 feet tall. The grass doesn't grow much at all during fall/winter, but it grows really fast during the spring/summer.

I am thinking that a full size utility tractor would be my best bet, especially if I go on vacation for a month during the summer, and the grass grows over 2 feet tall. I like the Mahindra 5500 4WD, 5530 4WD, and 5520 4WD. And I will be pulling a heavy duty 6 ft brush hog to mow the grass. I like the full size utility tractors better than compacts because they seem like they would be able to handle tall grass better, and can handle bigger tasks. But since these tractors weigh over 6000 lbs. (and even a couple thousand pounds more if I get a loader) could they make really deep rutts in the clay? especially during fall/winter when the ground is softer? or is the whole tires rutts thing just exaggerated and no big deal?

I know compact tractors are lighter, but I want a tractor that is more versatile and is not going to get stuck in tall grass.

Any suggestions?

Thanks

Not so sure you really need a utility tractor. I've never heard of any size compact tractor getting "stuck" in tall grass. You might need to mow in low gear/range but so long as you have a matched rotary or flail cutter you should be able to handle 12 acres with a 30-45 hp CUT without any problem at all. I'd think that something like the Kubota B3030 and a 5 ft cutter would be about the smallest and lightest tractor for what you are planning and you could probably justify going up to a 45 hp CUT with a six foot cutter but anything bigger would just be unnecessary unless you are planning to do a lot of plowing or other ground engaging work.

Welcome to TBN ArtVandelay.

Unfortunately, the simple answer is YES....you will make big beautiful DEEP rutts with the tractor if the ground is wet & soft. I also have pretty much the same conditions in my area although of course it freezes in the winter. But in the fall & spring I cannot get the tractor out for weeks at a time because I'll just create a mess & I have a lighter tractor than what your thinking of purchasing.

I do have turf tires & that helps a great deal. It's not so much the back tires but the front dig in deeper because they are narrower. Now if you keep the FEL off that would also help. Most first time buyers opt out for the R4 tires as a compromise between the better traction of an Ag style & the least amount of compaction with the turfs.

The best solution would be to have two tractors (one lighter & one big heavier beast), but most cannot afford it.

Personally, I recommend that you like the grass grow during the wet seasons, because once you made those ruts in that clay soil, you will be cursing yourself the next time that you try to mow over those old ruts. Whenever my Dad or myself get stuck and/or "plow-thru" a wet spot out in the farmland, we hate it come harvest time (with ruts). We also have to try and "level it out" come next spring IF it is dry enough to get thru. Usually, you drive around on the uphill side and disc downhill so you have gravity on your side if it is still to wet.

Best solution: Never make the ruts in the first place.​

PS: I just got a 150 HP tractor with a 14 foot windrower/cutter stuck on May 30th in 3 1/2 to 4 foot tall winter rye. I found the "wet spot". I should have gotten off of the tractor and physically walked that area first before driving thru. We did get it out with 75 feet of log chain and another tractor.

How bout a Mahindra 4110 4WD? I know it's not the lighest CUT out there, but it seems really heavy duty and nice. What size brush hog would I want to use for the 4110?

Welcome to TBN ! I agree with IslandTractor as to a tractor similar to the Kubota B3030. A 4WD/MFWD tractor that can handle a 5' rotary cutter would probably meet your needs. I maintain 12.5A's mixed woods (~5 A's) and sloped open field and "lawn"
(~7 A's) with a NH TC29DA (weighs ~ 3K#'s with weighted rears and FEL). I maintained this same property with a Ford 1100 (13HP/11+PTO HP) for over twenty years. My tractors never got stuck in the "grass" which can grow to over 6' or the numerous softwood saplings
(1" - 2" diameter), and I was always able to cut everything with a rotary cutter. I can not say the same about the mud or snow with the Ford when it came to getting stuck . Any tractor can leave ruts if the ground is wet enough especially if you have clay based soil and weighted R-1's. I have to be real careful on my "lawn" with my R-1's. Tire selection is important as to its impact on the soil, but tire selection should be based on primary uses. There have been many, many posts as to the relative merits and/or demerits of the different types of tires (weighted and unweighted) and primary use on surface soil. What is important is the tractor weight, ground clearance, and "footprint". If mowing will be your primary task you should look at lighter tractors and if you are interested in ground engaging tasks I would recommend a heavier tractor. You should share with the readership what your short term and long term projects are and the membership will assist you in spending your money. I will warn you that there are many HP junkies in TBN land . By the way my avatar is me coming out of my lower field while brush hogging. Keep the posts coming . Jay

If your main task is mowing tall grass than there's no question you don't need a utility, unless you're planning a mower in the 8' and wider range (which would be rather large for 9 acres).

A CUT in the 30hp range should handle a 6' mower without much trouble. Go up to 40hp if you really want - something like a Kubota L4400 would be good - but anything beyond that is needlessly big for a 6' mower. Just ask me, I have 47 PTO hp on my 6' cutter and it never bogs down while mowing at less than 1/2 throttle. Fortunately I have been doing some heavier tillage and loader tasks so my capability isn't all wasted. Once you get to a 7' or larger mower you are into medium duty mowers with high price tags and lots of weight, and a utility would probably be necessary for the weight if not the hp requirement.

It is best to stay off wet ground. I can tell you that loaded R1 tires will leave serious ruts on wet soil - they have the traction to keep going, but it damages the ground in the process. I mowed an area early this spring when soil was still wet and now I regret it when mowing in dry conditions - it is much bumpier than another part of the same field that I didn't mow in spring. Having said all that, R4 tires with nothing but air in them would be a lot better choice than loaded R1 tires for mowing on wet and soft ground. But it will still leave ruts. Only way to really avoid ruts would be a track machine, but that puts you into a whole new kind of pricing.

Mahindras are excellent tractors. Don't know that you really need that big a machine though. Depending on how often you need to mow and how much time you have I'd personally be looking at lighter tractors or at least something in the 30-40 hp range. Kubota, JD, NH, Mahindra, Kioti and a few other decent brands all make tractors in that range that would serve you well. Check out your local dealer situation as that should be a more important factor frankly than just horsepower. I don't think you need to worry about undersizing so long as you don't go below the Kubota B series 30hp and for my tastes anything over 40hp would be touching on too big. If you are just beating back weeds by bush hogging a few times a year I'd go for the 30hp end of the spectrum with a 5ft hog or maybe a light duty 6ft flail mower like a Caroni. If you want to cut so the pasture starts to resemble a lawn and want to keep it cut every 2-3 weeks then the bigger tractor and bigger mower would make sense.

I want to be able to run a 6ft Bush Hog at a good speed so that I get the 9 acres mowed in a reasonable amount of time, even if the grass is 3 feet tall. I will be mowing the entire 9 acres once every 2 weeks during the entire spring and summer. I might till about a 1/2 acre to grow some fruits and vegetables. And, I may need to remove a stump once in a while. That's what I will be using the tractor for.

Well, if you are mowing every 2 weeks it is unlikely you will be mowing 3ft tall grass except the first time in the spring. Depending on how rough your pastures are, you could either use a 6ft bush hog for a rough pasture with about a 35hp tractor or alternatively a 30hp tractor pulling either a 6ft light duty flail if there are not a lot of rocks or even a 6ft finish mower if the pasture is clean. Tilling half an acre is no sweat even for a 20hp tractor. Removing the occasional stump probably doesn't justify owning a backhoe but if the stumps are more than 6 inches or so you'll have trouble getting them out efficiently with just your FEL. Perhaps consider renting a BH occasionally.
