A: Cutting unit ground pressure can be varied within preset limits. It is controlled by the hand-wheel next to the lift/lower levers on the right-hand side of the operator's seat and is used to increase traction in wet conditions.
Turning it clockwise reduces the ground weight of the cutting unit, with more weight distributed to the drive unit. Traction is increased to better cope with a wet surface. Setting the weight transfer to maximum (+) will also help traction when mowing up and down slopes, but such work should be undertaken with care, keeping the speed low on the descent and never using the machine on a gradient greater than 15 degs.
Turning the hand-wheel anticlockwise will redistribute weight to the cutting units to reduce the likelihood of them bouncing when cutting undulating ground. The normal setting is midway between maximum and minimum.
You should find the instructions in the manual supplied with the machine. Alternatively, you can download a copy online at www.ransomesjacobsen.com/parkway2250-manuals.
It is wise to be thoroughly conversant with the safety instructions, controls, lubrication and maintenance of all machinery you use regularly. Such details are given in the user's manual and will help keep you safe and your machinery running smoothly.
