Versatility meets quality of cut where the F-30 flail heads of the LT-F3000 score is in their ability to offer a great halfway point between the cutting finish of a commercial cylinder mower with the versatility and rough mowing abilities of a rotary.
Key changes made to the latest Stage V models relate to the power unit. ‘First generation’ mowers are powered by a four-cylinder 44.2hp Kubota turbo diesel, a 43.4hp Yanmar turbo triple with DPF diesel particulate filter driving the current models.
The other key change is fitting CrossTrax hydrostatic drive as standard. This unique Toro all-wheel drive system links drive between the front wheels and their opposite number at the rear, automatically modulating power between the wheel drive motors. This is claimed to reduce wheelspin and turf marking in slippery conditions plus deliver good traction over steeply undulating ground without creating wheel scuff in a tight turn.
These ‘traction without scuff’ claims proved difficult to put to the test during my drive but when turning the mower at speed at full lock the LT-F3000 proved easy to spin round without cutting up the turf in the process. The ability of CrossTrax to keep going over slippery terrain and inclines, plus working on sidling ground, should be good but CrossTrax will put turf care ahead of ultimate traction. Where the traction is a priority, Toro offer conventional differential lock and 4WD in reverse as an option.
Easy Mowing
With separate forward and reverse travel pedals, using the mower is as easy as you would expect. The triplex flail units are raised and lowered via individual toggle switches, with drive engaged to each via separate yellow paddles. All controls are laid out in familiar Toro fashion.
In work, the engine is throttled up to full speed via the electronic throttle, dropping the engine speed to a fast idle delivering the full transport speed of around 15mph. That is a fuel saving bonus.
The travel pedals are well-weighted, enabling the working speed to be easily matched to prevailing conditions. The key to getting the best from the flails is to allow them to spin at full speed. Longer patches of scrub could be tackled at speed, short dense patches of grass responding well to a slower mow.
The need to slow down in dense grass was in part due to the mower being set at its lowest cut height of just 20mm or around 0.75 inch. This ‘scalping’ of infrequently mown ground demanded full power to cope with what turned out to be a thick matt of tangled grass.
What about the finish?
The mower did a great job. Cut material was well lacerated, which should speed its decomposition, and it was also distributed evenly across the mown width. Think cylinder clippings but fluffed up. Clipping spread was extremely well controlled. Working adjacent to a track, the spread of material from the mown to hard surface was minimal, with no need for a post-cut clean up. You could confidently work this flail mower alongside parked cars or in a public space.
The flails will allow some long stems to pass through uncut and flattened long material was left in the odd spot. As with all mowing systems, there will be compromises but overall, the flails did a great job. I doubt a rotary mower would have done better and a cylinder mower would just not be the right tool for the work tackled on the day.
That said, it would be interesting to compare to the finish between the F-30 flails and Toro four-blade Mk3 commercial cylinders as fitted to the LT3340 cylinder mower (6- and 8-blade units also available). On regularly maintained turf the chances are the cylinder mower would put up a stiff fight but over the ground mown during this test it would have been a hands down win for the LT-F3000 over the rough patches.
Toro does offer a cylinder kit for the LT-F3000, incidentally, so you can do a swap if you want but most will be happy to stick with just the flails. Not only do they do a great job, but their reduced maintenance demands are also a further point to consider. There are 16 Toro Tempest flails per F-30 head. Allow a short morning with a couple of spanners and all the flails can be renewed. If you are the one signing the maintenance cheque, it is easy to see why a flail mower will have its attractions.
A point to note, is that opting for flails has a downside. The LF-T3000 has a more powerful engine than a triple cylinder commercial mower such as the Toro LT3340. Cutting the same 2120mm in a pass, an LT3340 is likely to use less fuel, particularly over regularly mown grass. Mixed mowing in less-than-ideal conditions? A harder call.
My conclusion following the drive of the original LT-F3000 back in 2016 was that the only way to judge the system is to try it out. My drive this time around saw me mow over a few hidden lumps of concrete hidden in the turf, tackling patches of long, short and matted grass, plus some scrub and heavily weed infested ground. The mower tackled everything without fuss, delivering a decent looking ‘maintained’ finish in a single pass.
Would the LT-F3000 do a better job than something like a Toro Groundsmaster rotary mower? Would a commercial cylinder mower with four-blade reels have produced a better finish? As I said last time around, I cannot answer that but can say if you have not tried a flail mower you could be missing out on a truly versatile piece of kit. The LT-F3000 is popular for a reason.
