SCUT Mowing - Ground Speed?

[DK35vince]

Isn't that odd. The Land Pride website I linked to above clearly speaks differently to the blade tip speed.

I got my Land pride mower used several years ago and do not have an owners manual to look it up.

Here's a question for ZTR fans who get their mowing done quicker. The ZTR's advantages for trimming around obstacles are obvious. But if you figure you're going faster over open ground too, either the quality of cut is being sacrificed by going so fast or your mowing deck runs at much higher rpm's to keep up with the higher ground speed. Or maybe you mow more often so the grass isn't so heavy. I honestly want to know. At my place, the grass is heavy and going too fast means either disharge clumping or poor cut quality.

I'm using a ZD326P-60 and it will cut nicely at full speed 17kph (10MPH). The trick is to avoid wet grass, keep your deck clean and blades sharp. The other thing is that it's better to keep the grass trimmed regularly instead of letting it get really long. If it's too long you will need to cut it 2x at 90 degrees. It's just easier and faster to cut every 5 or 6 days in the growing season and you get no clumps on your lawn. I rarely cut twice, usually only after the first mow in spring if I let the grass get too long.

If your cut quality drops then its time to scrape the deck clean.

No trees? You can really fly.

Before the ZTR I had a 3ph 72 inch finishing mower on a CUT. What used to take me 3+ hours to cut about 3 acres on the CUT now takes me 45 minutes on the ZTR with a 60 inch deck. BTW I have lots of trees. On the straightways I run full tilt. I always run full throttle.

The negative on the ZTR is grass tear-up around sharp turns. It can also be a little hairy cutting on slopes and wet grass. It's like riding a pogo stick if you have rough ground but it feels like a racing cart on open ground.

The biggest advantage of the ZTR is speed. Around here all the commercial guys use the ZD's and there's a good reason why.

Oh and one big bonus for cutting fast - no bugs. No deer fly, black flies or mosquitos at 17kph. I used to get eaten alive.

So you are mowing an acre in 15 minutes with a 60" deck?

It's possible if you are truly averaging 10mph and there is little to no overlap. I would be surprised if one could do it unless they were mowing a grass airstrip!

 

[mikester]

It's about 3 acres with rows of trees included. Turns and mowing around trees slows you down. Wide open spaces go real fast.

Mike's in Canada. Probably has something to do with a Metric Minute, Imperial Acre or something that's different there.

I don't care who you are, that's funny.

No, stupid - it's the metric grass up here. It just cuts easier and is shorter!

Each of your machines has each own specific task.
Your Z can maneuver around fence posts, trees and other objects with ease.
It, further, can out distance your MMM due to two variances your tractor doesn't have....ground (forward) and blade tip (spindle rotational) speed.
Your tractor, as was explained to me by a tractor sales person, can accomplish several things on it's given platform.
Your Z has but one task.
To mow grass around many obstacles or in a straight line efficiently.
In short, a dedicated machine as opposed to a multi-functional but still needed one.

To answer another querry you posted, as I recall, mowing knee high grass is not so much mowing as brush hogging.
For that purpose, use your tractor with a dedicated rear mounted brush hog or, certainly, with your Z's deck raised to it's highest setting.
Z mowers utilitze blade tip speed to slash at grasses while tractors use more torque to accomplish the same task but without the finish you'll find with your Z's capability.

Then, with a wink to the Mrs., see?
I've saved us the funds by not purchasing a MMM and....
What we really need is an enclosed tractor with a Cab {Heat and AC}.

I rest my case
We're all pulling for you, Bro.

Can't thank everyone enough for all the advice. This thread really took off!

Looks like the consensus is keep the Z or be prepared to spend more time mowing. Since saving time is the driver for this whole thing, and I'll be mowing 80% of the time, I'm sure keeping the Z and renting a tractor when needed (as much of a pain as that is) will require less time overall, and certainly less $$$.

Will continue to keep me eyes open for a used SCUT, but going to hold off on a new one for now.

Thanks!

Trust me, I mow airstrips and farm/house layouts.

You will need both. But for pure time savings, the ZTR with ground and blade tip speeds cannot be beat.

Thanks! Lots of good info here.

@Code54 - My ZTR has a top speed of 8.5 MPH according to the spec sheet. I've never clocked myself, but when I'm mowing dry grass, I find that I'm pushing the controls 80-90% of the way forward while still getting nice cut quality and not bogging the engine at all. My yard is more or less wide open, and flat/smooth enough that I don't get too beat up even when mowing quickly. My ZTR does not have suspension. Glad to hear your comment at about 2 acres in 2 hours with your 60" MMM.

@TheMadOne / @rbtjr / @smstonypoint - Completely agree. 7-8 MPH is my guess at straight line speed. My average speed, including turns, is a lot less. My yard is pretty flat/smooth with the exception of one section (steep slope), and there are minimal obstacles. Based on tractors I've rented and driven in my yard, I could keep the pedal down for most of it, provided the engine and mower could keep up. I could also change my mowing pattern to avoid making 180-turns to increase the SCUT's average speed.

@Phillip w - Thanks. The enticing financing from some manufacturers ($0 down, 0% for 84 months) is what got me thinking about this in the first place. If a buy a SCUT, it will be financed. In reality, I could afford to keep my other toys, but it's just too much stuff and my wife wouldn't come close to agreeing to that.

@ovrszd / @newbury - You guys are getting at the core of my decision. I have some projects around the house appropriate for a FEL and backhoe - probably 50-60 hours of tractor work (grading, removing stumps, moving dirt/rocks, etc.). Once those are complete, unless I come up with new projects, the backhoe wouldn't get as much use, though I'm sure the FEL would come in handy. I would also be using the FEL for snow removal, and the 3PH might come in handy in the future if we start gardening more seriously. From a straight economics perspective, renting is cheaper. However, renting is not the easiest for me, as I have to borrow my brother's pickup to trailer the rental and dedicate a full day to make the most of it. With a full-time job, two-year-old daughter, and many other (non-tractor) projects, there's something to be said for being able to run out to my workshop, fire up the tractor, do an hour of work in between other stuff, and then put it away.

The issue is, if I keep the ZTR for mowing, sell the ATV, and buy a SCUT w/ FEL (no backhoe, no MMM), I've basically spent ~$11K for a really cool wheelbarrow/grader, and I'll still need to rent something to pull stumps. Thus, this seems, to me at least, to be an all or nothing conundrum. Either keep what I have and rent extra capability, or sell it all and replace two pieces of equipment with a "Swiss army knife."

How's the market for used backhoes attachments?

If you truly want a back hoe and you think the SCUT will work for digging, then get the TLB but skip the belly mower. Keep your ZTR for mowing which is what it is good at. Then you will have a good tractor for digging, hauling, pulling and the best mower for mowing. The best thing I ever did was buying my TLB. I didn't realize how bad I needed it till I got it. Sure sometimes it sets for weeks (months in winter) without use, but when I need it, it sure beats a shovel and wheelbarrow (my wheel barrow hasn't been used in almost 10 years). If you need to dig out stumps, pick up logs for trimming or cutting to fireplace size, dig out rocks, bury a pet or just dig a hole to plant a tree, a backhoe is a BACKSAVER. Most folks who say don't get one have never had one and only look at the cost and not the convenience. Digging with an FEL is a good way to damage the FEL, not very efficient and sometimes downright impossible to do.

I mow 7 acres with my JD x758. It isn't a SCUT, really, but it is pretty much the same size as one (i.e. JD 1025R). I have a 60" deck and mow about about 3 mph. I've learned this via both a GPS speed on my phone and the JD Mower Plus app that tracks your route and speeds. When I mow I'm mowing along at a good clip but I wouldn't call it 'fast'. Fast enough not to waste time but my yard is pretty bumpy so I don't go nuts. Lots of things can factor into your speed including grass type (thin, thick), wetness, height, bumpy lawn, how much stuff you have to mow around (trees, fences, gardens, sheds), etc. My yard is pretty busy and is not just a big empty rectangle.

I can mow these 7 acres in about 4.5 hours. Can vary from 4-5+ depending on grass height and wetness, but the 4.5 hour average is pretty consistent.

Hopefully this gives you some idea/info...
