Most remote-controlled brush mowers have a relatively low profile because they are designed with a low centre of gravity for stability while working on slopes.
The Timan, for instance, is 50cm high and will work at a maximum angle of 58 degs in all directions. When I saw it in action, the only limitation to it working on steeper gradients was fuel flow.
Power comes from a 15hp Honda petrol engine. The 75cm-wide cutting mechanism comprises 16 spade flail blades for short grass or 16 pairs of Y-blades for brushcutting. The machine weighs only 290kg. The Timan is available from Campey Turfcare of Macclesfield in Cheshire. List price is in the region of £20,750 + VAT.
Another machine I have seen working on banks is the German-made IRUS Deltrak, available from IPU Group of Oldbury in the West Midlands. It can tackle slopes of up to 50 degs. Standing nearly 1m tall, this machine is bigger and wider than the Timan, and it will cost more.
Two versions are available - 105cm wide with 30 blades and weighing 550kg or 125cm wide with 42 blades and weighing 650kg - both powered by 35hp Briggs Diahatsu turbo diesel engines maintained in an upright position by a "zero gravity articulating system".
At 75cm high, the RoboFlail rough cut remote mower from Simon Tullett Machinery is also worth a look. It is powered by a 25hp Kawasaki engine, gives a 122cm cut, weighs 540kg and is operable up to 45 degs.
An interesting variation is the Vario version with an out-front category 1 three-point linkage assembly that can be used to power post-hole augers, snow blowers, dozer blades or stump grinders. Prices start at around £30,000 + VAT.
Of a similar height is the Rotair Speedy-Cutter from Parts Depot. Two cutting widths are available - the 100cm machine is powered by a 24hp Honda engine and weighs 650kg while the 120cm unit has a 31hp B&S engine and weighs in at 720kg. Bank capability is 50 degs. Prices start at £24,175 + VAT.
With a height of 1.15m, the Robocut is a new remote from McConnel of Shropshire that will cut through material up to 30mm in diameter. It works to 55 degs and has the widest flail head in its class - 1.3m. There is a choice of Y or hammer flails.
If height is not a restriction, you might also like to look at the Kyoeisha Hammer Knife Mower from Roy Francis Plant Sales. This is a stand-on machine capable of mowing 35 degs banks.
