LOADER
The new MF11 front wheel drive loader has a high output 76 flywheel h.p., a 1 cu.m. (1-1/3 cu.yd.) bucket and a payload capacity of 1816 kg. (4,000 lb.).
Notable features include fast hydraulics, high manoeuvrability with

a small turning circle resulting from the use of small rear steering wheels, and a fine degree of operator comfort.
The bucket is automatically self- levelling. Good visibility is provided from the adjustable driving seat and speed and direction changes may be made on the run. Steering is fully hydrostatic.
Both rear fenders are hinged and can be swung clear to give total access to all components. The main braking system is self-adjusting; the batteries slide out on runners from a flap in the radiator grill; and all hoses are stand- ardised and fully interchangeable.
Dump height is 9ft. 2in. at a 45 degree bucket dump angle.
Hydraulic 'instant reverse' trans- mission is fitted, giving a two-pedal directional shift operated by the right foot. One pedal is for forward travel, the other for reverse; depressed to gether they accelerate engine revs for fast hydraulic response. The operator's left foot controls braking. Breakout force is 4540 kg. (10,000 lb.)
The makers are Massey-Ferguson Ltd., Banner Lane, Coventry, UK.
MIXER
A lightweight steel drum mixer produced by Millars' Machinery Co. Ltd., Bishop's Stortford, Herts., UK, is designed for mixing plaster or concrete in small quantities.
The drum has large paddles which ensure thorough mixing. A double grip lever provides the operator with easy control of drum loading /mixing and discharge positions.
Both drum and bevel pinion shaft are mounted in ball bearings that are lubricated and sealed for life. Chain drive via the bevel pinion provides con- stant mesh and speed with the engine and ensures against drum slip.
The compact dimensions of the machine, called the Bantam, enable it

to be handled by one person through doorways and its low weight makes it easy to load on to vehicles for speedy transport.
KERB MAKER
Kerbs and gutters can be laid at a fast rate by new machine which uses neither guide rails no formwork.
Made by Fowler Rex of Brookvale, N.S.W., Australia, it employs a method of extruding concrete. A patented re- ciprocating ram forces the concrete through a mould unit. This action simultaneously propels the machine forward.

kerb height. Level is maintained by the action of manually operated quick- acting height adjusting screws.
A variety of mould shapes can be fabricated to suit almost any desired cross section to 18in. high and 36in. wide with a sectional area not less than 50 sq. in. or more than 360 sq. in.
The Kerbmaker has a crew of three

one man controlling the machine. another the transit mixer guide chute and the third carrying out light finishing work with floats. It will lay kerb and gutter and the rate of 6ft. a minute.
CONCRETE STRESSING
A new automatic hydraulic jacking system enables a single operator to stress single wires or strands to pre- selected tensions up to 300 kN (30 tons) with an electronically-controlled accuracy of ±1 per cent. With the system, it takes less than 30 seconds to stress a 12,5 mm (in.) strand, lock off the anchor jaws, and retract the jack ready for the next operation. Any number of wires or strands in succes- sion may be stressed to the same ten- sion.
The system is manufactured by CCL Systems Ltd., Surbiton, Surrey, UK, under the name Stress-O-Matic Series II.
The basic system comprises a hydraulic pump-unit and three sizes of hydraulic jack which are known as 'stressing heads'; these have capacities of 6 tons, 16 tons and 30 tons and be- tween them can stress any wire or
