Born to per­form

Massey Ferguson 7720 Dyna-VT trac­tor

Farms & Farm Machinery - - Contents -

While the Massey Ferguson 7700 se­ries is a rel­a­tively new model, it is largely just a con­tin­u­a­tion of the pop­u­lar 7600 se­ries with a few tweaks.

The range stretches from 140hp to 255hp with two dif­fer­ent spec lev­els – es­sen­tial and ef­fi­cient – and three dif­fer­ent trans­mis­sion op­tions – Dyna-4, Dyna-6, and Dyna-VT. I’d say that cov­ers all the bases. For this test I had the 7720 Dyna-VT in the ef­fi­cient spec.


Un­der the bon­net is what used to be a SISU en­gine. This was re­cently re­named an AGCO Power en­gine. It is a 6-cylin­der, 6.6-litre tur­bocharged com­mon rail en­gine rated at 200hp with an in­tel­li­gent EPM (en­gine power man­age­ment) that de­liv­ers an ad­di­tional 25hp when de­manded.

As we have no­ticed in the past and again this year, these en­gines al­ways per­form well on the dyno and the read­ings are close to their stated horse­power.

This time, the 7720 de­liv­ered an im­pres­sive 199hp to the PTO shaft or 211hp once it was dis­cov­ered how to turn the boost on when the trac­tor wasn’t mov­ing.

The torque curve is equally im­pres­sive. Rel­a­tively flat, it shows plenty lug­ging power across the en­gine rpm range.

Euro­pean Tier 4 fi­nal emis­sions stan­dards have been met by sim­ply us­ing SCR (se­lec­tive cat­alytic re­duc­tion), which in lay­man’s terms is AdBlue sprayed into the ex­haust. This is a great, sim­ple so­lu­tion that doesn’t re­quire re­place­ment down the track or down­time with burn cy­cles.

The one down­side that could be ar­gued will be higher AdBlue us­age lev­els than other ma­chines with mul­ti­ple lev­els of emis­sion con­trols.

The diesel tank has an im­pres­sive 430-litre ca­pac­ity along with a 40-litre AdBlue tank.


A re­li­able Dyna VT con­tin­u­ously vari­able trans­mis­sion (CVT) is used in the Massey Ferguson 7720.

This is essen­tially ex­actly the same as those found in the other pre­mium brand trac­tors sold by AGCO ex­cept it is priced cheaper, which sounds like a win to me.

In op­er­a­tion, it is ex­tremely smooth and ef­fec­tive at de­liv­er­ing the power to the ground un­der load. The field and road mode ranges limit for­ward speed to op­ti­mise torque and con­trol, depend­ing what the trac­tor is be­ing used for.

While there is a lot of func­tion­al­ity built into this trans­mis­sion — where most as­pects such as the ag­gres­sive­ness or the re­la­tion­ship be­tween for­ward/re­verse speeds can be ad­justed — my opin­ion is that these ad­just­ments are not very in­tu­itive and will re­quire some se­ri­ous study­ing of the man­ual to get the full ben­e­fits.

On the pos­i­tive side, though, it is straight­for­ward to get in the trac­tor and get mov­ing.

The move­ment is eas­ily con­trolled by the foot pedal or joy­stick on the right-hand arm­rest.

The joy­stick is sim­ply pushed for­ward or back­wards to con­trol the trac­tor’s speed, and it is great to see that there are but­tons on top of both joy­sticks to change direction as well as a left­hand shut­tle lever.


For a 200hp trac­tor, the en­gine is still slung nice and low to the ground. This not only in­creases sta­bil­ity but also makes ser­vic­ing and daily checks re­mark­ably easy to per­form from ground level.

The oil can be checked with­out open­ing the bon­net, and an­other great idea is a third ex­tra fuel fil­ter to en­sure that any con­tam­i­nates which might be in the fuel are re­moved be­fore get­ting to the en­gine.

Its fi­nal des­ti­na­tion was Mt Rid­dick sta­tion in the North­ern Ter­ri­tory, where it was put to work pulling stock crates through the never-never.

The Massey Ferguson 7720 is also one of the few trac­tors to use sep­a­rate trans­mis­sion and hy­draulic oils.

This has the ben­e­fit of rul­ing out any cross con­tam­i­na­tion to the trans­mis­sion when hitch­ing up im­ple­ments with oil in them, which is a great fea­ture.

Ser­vice in­ter­vals sit at 250 hours for the en­gine, 1000 for the hy­draulic oil, and a mas­sive 2000 for the trans­mis­sion oil.

A two-year or 2000-hour war­ranty pro­vides peace of mind for new own­ers.

I found it in­ter­est­ing that the cool­ing packs are fixed in place and don’t open out like many other trac­tors. Sup­pos­edly, this is be­cause Massey Ferguson be­lieves hinge points cre­ate weak spots and un­nec­es­sary wear, which I guess does make sense.

The ra­di­a­tors are still ar­ranged so they are easy enough to clean. Diesel and AdBlue tank fillers are where you would ex­pect to find them – log­i­cally be­side the left-hand steps to the cab and are colour-coded to help pre­vent con­fu­sion.


Massey Ferguson has stuck with its dis­tinc­tive six-pil­lar design cab. Al­though there are ex­tra pil­lars that get in the way for vis­i­bil­ity, many feel that the curved rear-side win­dows make up for any­thing that is lost. It’s the same story for the doors. Any­thing lost in terms of ac­ces­si­bil­ity com­pared to large sin­gle­piece doors on other trac­tors is made up for in how easy they are to open and close.

Once in the cab and on the air seat, the en­vi­ron­ment feels light and open. Vis­i­bil­ity out the front is good thanks to a slop­ing bon­net and a ta­pered chas­sis. Al­though the pas­sen­ger’s seat feels more like a perch than a seat, we all know they are there for train­ing pur­poses only.

Me­chan­i­cal cab sus­pen­sion of­fers up a smoother ride, as does the re­designed front-axle sus­pen­sion with more than 100mm of travel to soak up the bumps. This uses two hefty hy­draulics set out at an an­gle from the chas­sis to the axle, giv­ing good sta­bil­ity un­der load.

The dash tilts for­ward with the steer­ing wheel and is clear and well laid out. It now uses a colour dis­play, in­clud­ing in­for­ma­tion such as trac­tor per­for­mance, work rates, fuel con­sump­tion, and oper­at­ing tem­per­a­tures.


The con­trols are quite spread out around the cab, which some­what de­tracts from the func­tion­al­ity. First up on the arm­rest, the main joy­stick con­trols move­ment of the trac­tor.

Among other things, it has but­tons for the rear link­age, one pro­gram­mable re­mote valve, and two cruise con­trol set speeds.

Also on the arm­rest is a hand throt­tle and pre-set en­gine rpm but­tons, along with a sec­ond joy­stick that of­fers great con­trol for the front link­age or if a loader is fit­ted.

It is good to see but­tons to con­trol the direction of travel. Con­trols for the re­main­ing re­motes are found on the right-hand con­sole and are a mix of levers for the me­chan­i­cal re­motes and fin­ger­tip tog­gles for the elec­tric ones.

The rear PTO on this trac­tor has four speeds, which is more than many other ma­chines.

Speeds are se­lected via but­tons found at the top of the cab’s

‘B’ pil­lar, while the PTO on/off is found on the right-hand con­sole. Al­most all other con­trols are laid out down the ‘B’, which puts them in easy reach but slightly out of your eye line when driv­ing. The ig­ni­tion key is also found on this pil­lar.

The Data­tronic 4 dis­play mon­i­tor uses a 7-inch colour screen to dis­play in-depth info, form work rates to how the trac­tor is set up, and al­lows greater con­trol of var­i­ous func­tions.

It can also be used to set up head­land man­age­ment se­quences, al­low for a single-cam­era in­put, and is fully ISOBUS com­pat­i­ble,

al­low­ing im­ple­ment man­age­ment screens to be dis­played.

While this mon­i­tor is ad­e­quate, in com­par­i­son to most other trac­tors it is quite small, lacked func­tion­al­ity, and can be a lit­tle dif­fi­cult to nav­i­gate through the dis­played info.


A closed-cir­cuit load-sens­ing hy­draulic sys­tem uses a vari­able dis­place­ment swash plate pump, which is rated to put out 110 litres of oil per minute. Im­pres­sively, in­de­pen­dent tests man­aged to get a max­i­mum of 102L/min out of a single spool, which is more than ad­e­quate for most tasks.

Car­ry­ing seven sets of hy­draulic re­mote valves made up of four at the rear and three at the front, in­clud­ing one to op­er­ate the front link­age, pro­vides plenty of op­tions. Of the four rear re­motes, two are elec­tronic and two me­chan­i­cal.

The Massey also still has me­chan­i­cal re­motes. Re­lease levers on the rear cou­plers are great to see and make un­cou­pling hoses easy.

In the cab, con­trols for the hy­draulics are a lit­tle mixed and con­fus­ing. There is a cross-gate joy­stick on the arm­rest for two re­motes, some push but­tons on the top of the main joy­stick to con­trol a fur­ther set, and three fin­ger­tip but­tons on the right­hand con­sole.

Con­trol can be can be swapped and Massey has pro­vided lim­ited abil­ity to as­sign re­motes to dif­fer­ent con­trols through the mon­i­tor. The two me­chan­i­cal spools use levers found on the right-hand con­sole.

Flow rates can be ad­justed on the Data­tronic screen. Load­sens­ing power be­yond valves and a hy­draulic trailer brake at the rear were good to see.


Sim­ple and ef­fec­tive link­age con­trols are im­por­tant and they are fairly straight­for­ward in the Massey. There are up and down but­tons on top of the main joy­stick as well as a scroll wheel down the side of the arm­rest for fine con­trol of the height.

As you would ex­pect, there are con­trols for max height, raise/ drop rate, draft etc., which can all be eas­ily ad­justed. I don’t like the fact that the link­age must first be un­locked be­fore it will move even when us­ing the ex­ter­nal con­trols, but I know ev­ery­one will say it’s for safety.

The rear lift ca­pac­ity is stated at 9900kg at the Cat 3 hook ends, which made hitch­ing the trac­tor to a Sumo Trio straight­for­ward. Sta­bilis­ers were also eas­ily ad­justed.

Ex­ter­nal but­tons to con­trol the rear link­age are on both rear mud­guards, as well as a PTO stop but­ton – great to see and help­ful when hitch­ing im­ple­ments.

The front link­age has a re­spectable lift ca­pac­ity of 4000kg, which will prove more than am­ple for most tasks.

In­ter­est­ingly, this is one of the few trac­tors with a front link­age but no front PTO, which does limit use­ful­ness, but a front PTO is def­i­nitely an op­tion.


Put through its paces out in the field on a 3.5m Sumo Trio, the Massey per­formed ex­cep­tion­ally well. The 6.6-litre en­gine poked out plenty of power across a wide rpm range. The trans­mis­sion

is good at get­ting this power to the ground with min­i­mal losses and keep­ing the trac­tor mov­ing for­ward at a rea­son­able speed even un­der tough con­di­tions.

Hitched up to a Her­ron trailer (with a gross weight of more than 21 tonnes), the trac­tor once again proved it­self and was more than com­fort­able get­ting smoothly up to speed. It felt well bal­anced with this weight be­hind it and there were no prob­lems stop­ping with the help of the hy­draulic trailer brakes.

As men­tioned ear­lier, dyno re­sults were im­pres­sively close to the stated max en­gine rpm, set­ting the Massey apart as one of the few trac­tors where you ac­tu­ally get the horse­power that you have paid for. Fuel us­age on the dyno sat at 38.9L/h which, when worked out on a horse­power ba­sis, was an im­pres­sive 0.195 litres per horse­power per hour.


Over­all, there are some pleas­ing re­sults for the Massey

Ferguson 7720. The AGCO power en­gine did ex­cep­tion­ally well on the dyno and was close to its stated horse­power, giv­ing real value for money when it comes to power. These re­sults were in line with our find­ings in the field, where it got the power to the ground and pulled ex­cep­tion­ally well.

The build qual­ity is ex­cep­tional through­out and the sus­pen­sion setup of­fered a smooth, well-bal­anced ride. The hy­draulic sys­tem also per­formed well and the trac­tor had a higher num­ber of re­motes than most. While oth­ers are more func­tional in terms of cab lay­out, the de­ci­sion lies with how much func­tion­al­ity is re­quired and some­times good eco­nomic re­li­able horse­power is hard to beat.
