77-Series

Available with reach options from 5.5m to 7.0m and powered by high performance 70hp or 85hp hydraulic system, the new heavy-duty 77-Series has been designed for farmers, contractors and local authorities and features new design style which marks the arrival of McConnel’s next-generation Power Arms. 

The 77-Series also includes larger diameter pivot pins, allowing for a 48% increase in bush area for added durability and longevity. An 85hp hydraulic system is available as an option for those seeking more power.

Among the key new features of the machine is the restyled 180 litre hydraulic tank that incorporates a two-piece rear guard and sculpted polypropylene top cover.  Designed to improve access to the hydraulic system, the new rear guard is hinged at one-side to enable quick opening for easy access for maintenance. 

The new one-piece top-cover is sculpted from impact resistant polypropylene and designed to minimise material build-up and prevent the ingress of dust and moisture.

An optional integrated debris blower is located within the rear guard, which clears roadside debris and enhances cooling by drawing in cool air over the pumps and tanks. 

 

Overview

Seven different armsets including 5.5m and 6.0m straight-arms, 6.5m and 7.0m telescopic arms, and a 5.5m & 6.0m Variable Forward Reach (VFR) option.  VFR enables operators to position the flailhead alongside the cab for enhanced visibility and comfort.  VFR also aids manoeuvrability when cutting around obstacles and working in confined environments such as narrow lanes.

Advanced arm features that are synonymous with McConnel Power Arms such as; Hy-reach geometry, parallel arm geometry, and Power Slew are all standard features on the new 77-Series. 

At the heart of the machine is a 70hp or 85hp gear hydraulic system that utilises McConnel’s in-house designed and manufactured hydraulic valve block.  Designed specifically for McConnel Power Arms, the high-performance hydraulic system includes electric rotor control, Soft-Start rotor engagement and a high-capacity oil cooler as standard.

Mounting

All models utilise a heavy-duty mainframe that’s designed for 3-point linkage mounting.  Users looking to added further stability or to reduce stresses on tractor linkage can opt for either the 4-point hitch or 5-point axle mounting sub-frame, both of which can be retrofitted.

Innovation

The 77-series include an optional integrated debris blower located within the rear guard, which clears roadside debris and enhances cooling by drawing in cool air over the pumps and tank.
