A fast, low-effort way to maintain a larger lawn, the Alpina BL51 SQ combines a substantial 51cm working-width with a roomy 55-litre grass-collector and a rear-wheel power-drive.
Powering the BL 510 SQ is an Alpina ST140 engine; a highly efficient and clean-running 139cc OHV unit that’s rated at an impressive 2.2kW; and which will prove quick and easy to start thanks to Alpina’s Auto-Choke system.
This high-quality but affordable lawnmower has been constructed around a robust steel chassis that confers a reassuring level of durability and provides a solid platform for the rest of the machine.
A vertically-adjustable handlebar ensures you’ll be able to mow in comfort, whatever your height; while single-point height-of-cut adjustment makes selecting the most effective blade-setting a no-hassle operation.
So as to help you manage a variety of grass-conditions, the BL 510 SQ has been equipped with four mowing-modes: mulching; bagging; side-discharge; rear-discharge.
