Despite the gelding's age, trainer Michael Trinder expects him to run well after two recent trial wins.

"His trial form has been exceptional." Trinder said.

"And, his synthetic track form is very good - his grass track form is very much inferior."

Spihro has been a great money-spinner for connections since being bought in Sydney for only $5000.

"He was a $180,000 yearling, being by Lonhro out of a Danehill mare," Trinder said.

"He's now won 10 races and more than $150,000.

"But this will be his last throw at the stumps.

"He will then be retired as a show horse and go eventing."

Trinder said a couple of unplaced runs before the shutdown had seen Spihro's rating drop and he was well placed in Sunday's Benchmark 66 Handicap.

"Considering his record, he's very well weighted (on 61kg)," the trainer said.

"And, Brendon (McCoull) has a good record on him, as he pointed out to me the other day."

Trinder has also booked McCoull for his two other runners at the meeting - stable newcomer Rubyranger in the Maiden Plate and Mag Wheels in the Benchmark 60 Handicap.

Trainer David Hayes has entered a new chapter of his harness racing career after joining forces with leading owner Mick Maxfield at his East Devonport stables.

Hayes took over the Maxfield team about a month ago and has 12 horses in work "at various stages of their preparations".

Two of them, Krafty Boy and Shaun To The Max, will run at Mowbray on Sunday night.

Krafty Boy had his first start for Hayes at the same track last week and the trainer thought he was a little unlucky.

"He was up there early but got shuffled back then didn't really get a run at them," Hayes said.

"But he's drawn bad in a pretty tough race this week."

Two-year-old Shaun To The Max had three unplaced runs for Maxfield's former trainer Paul Ashwood earlier in the year.

"We haven't been able to trial him but he's had those previous starts so we decided to put him in," Hayes said.

"All the horses have been well educated by Paul - I've just had to work out my own way of working them.

"They were kept jogging during the shutdown and they all seem to be ticking along pretty well."

Hayes said he was looking forward to the challenge of training for one of the state's biggest-ever owners.

"It's another chapter for me - I'm working on a beautiful property with great facilities," he said.

"And, Mick is a great supporter of harness racing - he has bought and bred a lot of nice horses."

Jockeys will wear black armbands on Sunday as a mark of respect for three industry stalwarts who have passed away in recent weeks.

Tasmanian sporting icon Paddy Martin, 92, was a former treasurer of the Devonport Racing Club and a successful racehorse owner and trainer.

Devonport sports commentator and administrator Shane Yates, 60, also had a lifelong involvement in racing including 44 years as a racecaller.

Long-serving Victorian clerk of the course Graham Salisbury, 76, became famous for his community and promotional work with Melbourne Cup-winning cult hero Subzero.
